Everything You Need to Know About Protein and Bone Health

Nutrition / Nutrition / July 3, 2020

There’s a common misconception that could be wreaking havoc on your bones… 

The misconception? That a high protein diet is bad for bone health. 

But nothing could be further from the truth! In fact, years of research show that getting plenty of protein is crucial for bone density — provided you get enough of a certain key mineral. And that increasing your protein intake can help you stay strong, healthy, and independent as you age.  

That’s why we’re taking a deep dive into the research on protein and bone health, including the truth behind the much debated “acid-ash hypothesis”. We’ll also break down exactly how much protein you need and the best places to get it. 

 So let’s get started!

The Basics on Protein and Your Bones

Proteins are your body’s “building blocks”. In fact, they form the foundation of every living thing!

Yes, bone, muscle, hair, blood, tissue, immune system antibodies, and vital enzymes are all built with proteins. So without them, your body’s ability to maintain, grow, and repair tissues is compromised. But what are proteins, exactly? 

Under a microscope, proteins are made out of long chains of amino acids linked together like lego blocks. All told, there are 20 amino acids needed for metabolism and human growth. 

Eleven of these are classified as nonessential — meaning your body can produce them, so you don’t need to get them through your diet. Nine of these are classified as essential — meaning your body can’t produce them, and you have to get them through your diet! 

And when it comes to your bones, protein is especially important. Protein makes up roughly one third of your bone mass (the amount of protein your bones contain) and half of your bone volume (the amount of space protein takes up)! 

The protein in your bones is continuously broken down and built back up, as part of your bone remodeling process. And unfortunately, the protein that’s broken down isn’t reabsorbed and reused. That’s why you need a daily supply of protein to maintain your bone density. (We’ll go over the ideal amount a little later on!)  

Protein also works closely with calcium. And of course, calcium is a key mineral for bone health. So next, we’ll take a closer look at the relationship between protein and calcium. Plus, we’ll debunk the common misconception I mentioned earlier…

Calcium and Protein Work Together

You need a balance of calcium and protein for strong, healthy bones. 

Research shows these nutrients complement each other. Specifically, when you get adequate calcium in your diet, a higher protein intake benefits bone mineral density (BMD) and reduces hip fracture risk. 

Let’s break down the research:

Studies on protein intake and bone mineral density

  • Study Link: https://academic.oup.com/ajcn/article/75/4/773/4689385

    Design: Randomized placebo-controlled trial 

    Summary: The goal of this study was to determine the effect of calcium and vitamin D supplementation, along with protein intake, on bone mineral density (BMD). 

    The participants included 342 men and women, aged 65 and older. Half of these participants supplemented with calcium and vitamin D and the other half took a placebo pill. Participants’ protein intake was established using a food-frequency questionnaire and BMD was assessed every 6 months by DEXA scan. 

    At the end of the three-year study period, researchers found that higher protein intake was significantly associated with a favorable change in BMD — but not in the placebo group! These results indicate your bones need both adequate calcium and protein to thrive.

  • Design: Expert scientific paper

    Summary: Dr. Robert P. Heaney was a distinguished professor of medicine, a leading researcher in the field of bone health, and an expert on calcium and vitamin D. He wrote an insightful review on the relationship between protein intake and calcium balance. 

    In this review, he established the interdependence of these two nutrients for bone health. He pointed out that a large body of evidence shows beneficial effects of protein intake on BMD, including the well-respected Framingham Osteoporosis Study. He also cited the calcium and protein intake trial we just discussed. 

    But Dr. Heaney took his analysis a step further. He delved into his database of metabolic balance studies in mid-life women to explore the interaction of calcium and protein. From this data, he established that, “calcium intake without adequate protein showed no significant relation to bone mass”. That’s a pretty notable statement!  In other words, you can take all the calcium in the world and it does no good for your bones if you don’t also eat adequate protein.

    All in all, Dr. Heaney concluded that studies show high protein intake is osteoprotective, if calcium intake is adequate. And of course, he noted this relationship goes both ways — the bone protective effects of calcium are evident only when protein intake is high.

  • Study Link: https://link.springer.com/article/10.1007/s00198-018-4534-5

    Design: Expert consensus paper — a summary of systematic reviews and meta-analyses 

    Summary: In one of the most comprehensive reviews of research to date, a group of bone health experts looked into the relationship between protein, calcium, and bone health. They analyzed over 100 high-quality studies to come to their conclusions. 

    Here are the key takeaways from their analysis: 

    • “Hip fracture risk is modestly decreased with higher dietary protein intakes, provided calcium intakes are adequate.” 
    • “Bone mineral density (BMD), which is an important determinant of bone strength, appears to be positively associated with dietary protein intakes.”
    • “Protein and calcium combined in dairy products have beneficial effects on calciotropic hormones, bone turnover markers, and BMD. The benefit of dietary proteins on bone outcomes seems to require adequate calcium intakes.” 
    • “There appears to be no direct evidence of osteoporosis progression, fragility fractures, or altered bone strength with the acid load originating from a balanced diet.”

    In plain English, a high protein diet with adequate calcium protects your bones!

Bone Health Benefits of Protein

So we’ve seen how protein is crucial for your bone remodeling process. We’ve also seen how a high protein diet along with adequate calcium can protect your bones! But that’s not all… 

Here are three more bone health benefits of protein:

Icon of bone structureProvides the Structural Framework for Bone

Your extracellular bone matrix is primarily made of collagen, and yes, collagen is a protein! This soft collagen matrix is like a flexible framework for bone. Calcium hardens this framework and adds strength to it. Together, collagen and calcium make your bones strong, yet flexible enough to withstand stress. 

Of course, there’s more to bones than collagen and calcium, but they’re undoubtedly two of the key ingredients! This is yet another example of how protein and calcium work together to support your bone health.

Icon of growth factor

Increases Insulin-Like Growth Factor 1 (IGF-1) Levels

We touched on IGF-1 briefly a little earlier on. If you recall, protein stimulates the production of IGF-1 — and IGF-1 boosts calcium absorption! Of course, this function favors your bones. 

But IGF-1 does much more than that. This hormone is key for bone growth. It also enhances muscle tissue and strength, which in turn, supports bone strength. Remember, your muscles and your bones are tightly intertwined… that’s why it’s called your musculoskeletal system! More on this point next.

Icon of muscle mass

Crucial for Your Muscle Mass and to Prevent Sarcopenia

Just like protein is crucial for the structure of your bones, it’s also a building block for your muscles. And just like your bones, your muscles are constantly rebuilding in response to the daily stressors of life. 

So when you don’t consume enough protein, your ability to produce new muscle and replace damaged muscle is compromised. Over time, this leads to a lower rate of muscle protein synthesis and a loss of muscle mass. 

Plus, as you age, your ability to use the protein you consume to build muscle (called your anabolic response) lessens. That’s why, older adults need to consume more protein than young adults to maintain muscle mass.

The point being, if you’re not proactive about getting enough protein as you age, it can lead to sarcopenia — a condition where your muscle mass shrinks and your muscle cells are replaced by fat. 

What does all this have to do with your bones? Well, like I mentioned in the previous bullet, your muscles and your bones are closely linked. After all, muscle contractions put stress on your bones and stimulate them to rebuild! 

So you can see how sarcopenia is bad news for bone health. In fact, sarcopenia and osteoporosis are strongly associated with each other, as well as with the frailty syndrome — a condition characterized by weakness, slowness, reduced physical activity, reduced energy, and weight loss. 

All this to say, it’s worth making sure you get enough protein every day. For your bones, your muscles, and your overall quality of life.

Debunking the Acid-Ash Hypothesis

There’s been much debate over the “acid-ash hypothesis”.  

In brief, this hypothesis suggests that high protein intake (particularly from animal sources) leads to increased acid production and bone resorption. This is attributed to high levels of sulfur-containing amino acids in animal proteins, which generate an acid load.

The idea is that the body tries to neutralize this “acid load” by recruiting calcium from bone, which leads to hypercalciuria (excess calcium in urine), bone loss, and osteoporosis. (For a more in-depth explanation of the acid-ash hypothesis — also called the alkaline diet theory — visit this page.) 

Now, this hypothesis is supported by animal and cellular studies. But not so fast! This is a perfect example of how preliminary research can be misleading. See, animal and cellular studies don’t always translate to humans, and this is one of those instances.

First off, your body is well-equipped to regulate your acid load. Your kidneys and lungs work as a team to maintain “acid-base homeostasis”. That is, a healthy balance of acid and alkaline (neutral) substances in your body. So generally, excess acid from food is easily dealt with. (Note there are exceptions to this rule, like for people with chronic kidney disease.) 

All this to say, acid production from a high-protein diet is unlikely to (even slightly!) affect this balance. 

So what gives with the studies that show high protein intake increases urinary calcium loss? Well, for starters, excess calcium in urine doesn’t necessarily come from increased bone resorption — like the acid-ash hypothesis suggests. There are several alternate mechanisms that could be at play. 

For example, higher protein intake leads to higher calcium absorption. That’s because protein stimulates the production of something called insulin-like growth factor 1 (IGF-1). In turn, IFG-1 increases the production of calcitriol — an active form of vitamin D that increases intestinal calcium absorption!

So the resulting excess calcium in urine could, in part, be due to increased calcium absorption. Of course, this theory requires more study, as the research so far has been small-scale. But an alternate mechanism (or combination of mechanisms!) seems more likely in face of the many human studies that show the benefits of a higher protein diet for bone health.

(Incidentally, this relationship between protein, IGF-1, and calcium absorption may contribute to the positive effects of high-protein with adequate calcium we saw above! More on IGF-1 coming up in the next section.) 

Still not convinced? Here’s a snapshot of studies that cast doubt on the acid-ash hypothesis:

Studies on the acid-ash hypothesis

  • Study Link: https://asbmr.onlinelibrary.wiley.com/doi/full/10.1359/jbmr.090515

    Design: Meta-analysis 

    Summary: In this meta-analysis, researchers identified five clinical studies that looked at calcium balance in relation to the acid-ash hypothesis. These studies manipulated the amount and/or the type of protein participants consumed. Then, they assessed the effect of different protein intakes and types on net acid excretion (NAE), urinary calcium, and calcium balance*.

    *Note calcium balance refers to the difference between calcium intake and output in the body. 

    Now, the researchers did find an increase in NAE and urinary calcium. BUT this relationship didn’t extend to calcium balance or markers of bone metabolism. In other words, this analysis found that excess urinary calcium didn’t reflect a loss of whole body calcium! 

    The researchers concluded there was no evidence increasing diet-derived acid load leads to bone resorption, bone loss, or osteoporosis.

  • Study Link: https://pubmed.ncbi.nlm.nih.gov/18689384/

    Design: Randomized Placebo-Controlled Trial

    Summary: Now, if the acid-ash hypothesis is true and a high acid load leads to bone loss, then the opposite should also stand. Namely, that a low acid or high alkaline diet would have bone protective effects. So researchers set out to investigate the flip side of this theory… 

    They conducted a randomized placebo-controlled trial, including 276 post-menopausal women between the ages of 55 and 65. Participants were assigned to four groups: high-dose potassium citrate (alkaline), low-dose potassium citrate (alkaline), placebo, or 300 grams of additional fruits and vegetables a day (alkaline). Blood and urine samples were collected throughout the study to assess bone markers, and BMD was measured at baseline and after two years. 

    In the end, they found the average BMD loss wasn’t significantly different between the placebo group or any of the intervention groups. They concluded that an alkaline treatment doesn’t slow bone loss or increase BMD in postmenopausal women. 

    Of course, we know your body needs multiple minerals and vitamins to increase BMD, so these results aren’t terribly surprising. But if the acid-ash hypothesis were true, you’d expect to see at least a small reduction in the rate of bone loss for the intervention groups!

  • Study Link: https://pubmed.ncbi.nlm.nih.gov/21529374/

    Design: Systematic review and meta-analysis

    Summary: The objective of this study was to evaluate whether there’s a causal relationship between dietary acid load and osteoporosis. The researchers identified 22 randomized controlled trials, two meta-analyses, and 11 observational studies that met their quality standards. They also examined 19 cellular studies to access the hypothesized “acid-ash” mechanism. 

    All in all, a very thorough investigation! 

    The randomized controlled trials, meta-analyses, and observational studies measured bone health outcomes, including: urinary calcium, calcium balance, BMD changes, and fractures. These measures were taken for participants whose acid and/or alkaline intakes were manipulated or observed. 

    Now, urinary calcium excretion rates were consistent with osteoporosis development. But, and this is a big but, calcium balance wasn’t affected by higher net acid excretion. What does this mean? Well, participants developing osteoporosis were certainly excreting more calcium… but acid load wasn’t the culprit! 

    In fact, none of the intervention studies provided direct evidence of osteoporosis progression due to acid load. (And that includes fragility fractures and bone strength.) The researchers concluded that the acid-ash hypothesis for osteoporosis isn’t supported by evidence.

So How Much Protein Do You Need?

Despite all the benefits of a higher protein intake discussed so far, you’ll find most official health organizations and websites recommend a modest amount. 

The current recommended daily allowance (RDA) for protein intake is 0.8 g per kg of body weight. But this RDA was set over a decade ago, and experts now believe it’s not an adequate amount. Especially for older adults…

The original RDA for protein was set with preventing a deficiency in mind. Not for promoting optimal health. And the recommendations were based on studies conducted in young, healthy adults. So the RDA fails to take into account the physiological changes that occur with aging.

Changes that occur with aging include:

  1. Sarcopenia – As discussed, you start to lose muscle mass every year as you age. The exact amount of muscle loss varies from person to person, but research suggests the average rate of muscle loss for people over 70 is 0.5-1% per year.
  2. Reduced Ability to Make Muscle – Again, as discussed, you start to develop an anabolic resistance to amino acids as you age. In simple terms, that means you become less efficient at turning the protein you consume into muscle.

So bearing these points in mind, more recent research recommends older adults consume 1-1.5 g of protein per kg of body weight. And here’s why you may want to err on the side of 1.5 g… 

In the latest double-blind randomized controlled trial (the gold standard of research!), 120 frail or close to frail adults, between the ages of 70 and 85, were assigned to one of three groups: 

  • Group one received 0.8 g of protein per kg a day
  • Group two received 1.2 g of protein per kg a day 
  • Group three received 1.5 g of protein per kg a day 

After the 12-week study period, the participants who received 1.5 g of protein per kg a day experienced the most beneficial effects (measured by muscle mass and walking speed). Notably, there were no significant differences between the 0.8 and 1.2 g of protein groups! This suggests a higher protein intake is necessary to counteract sarcopenia and frailty.  

So how much protein does 1-1.5 g equal in practical terms? 

Well, for your average 130 pound woman, 1.5 g of protein per kg would translate to about 30 grams of protein at each of your three meals during a day. (Check out the infographic below to see how to calculate your exact needs!) But there’s an important thing to note: To maximize your body’s ability to use this extra protein to produce muscle, it’s best to separate your meals by three to five hours.

But again, these are just updated guidelines. For the most accurate calculation of your protein needs, you must take your age, body weight, and activity level into consideration. That sounds complicated, but don’t worry! The visual below makes it easy for you.

How to calculate your protein needs

Top Food Sources of Protein

Calcium uses, effects - older couple making bone healthy food

What makes for a “high-quality” protein? 

Well, there are several factors to take into consideration, including the amount of protein per gram, whether it’s a complete or incomplete protein, and how it’s raised (grass fed vs. grain fed, organic vs. factory farmed, etc). 

Let’s take a closer look at how the different types of protein stack up…

Animal Protein Vs. Vegetarian Protein

Animal protein has a couple of advantages over vegetarian protein. 

First off, if you look at the amount of protein per gram, animal protein wins out. In general, vegetarian protein sources fall a short of the protein content animal sources offer so you need to eat more calories with plant proteins which can be an issue if you’re concerned about controlling body fat. 

Second, all animal protein sources are considered complete proteins. That means they provide all eight essential amino acids you need to get from your diet. On the other hand, vegetarian proteins are typically incomplete, meaning they lack one or two of essential amino acids. (Note there are a few exceptions to this rule, like quinoa and soy.)

Of course, that’s not to say you can’t fulfill your protein needs through vegetarian sources. It’s just a little trickier to do! 

If you’re a vegetarian or vegan, the key is to consume a variety of fruits, vegetables, grains, and legumes to ensure you get all the essential amino acids. For a more in-depth look at vegetarian protein, visit our “Vegetarian’s Guide to Protein and Collagen”.

It’s also worth noting that whenever possible, it’s best to choose grass-fed, wild-caught, and organic protein sources to minimize your exposure to pesticides and other chemicals. That’s because these chemicals can cause bone-damaging inflammation

Finally, as we saw a little earlier on, there’s been some debate about whether animal proteins increase acid load and urinary calcium excretion. If you recall, the theory is that animal proteins generate more sulfuric acid from sulfur-containing amino acids. But a strict vegetarian diet, with protein from grains and legumes, can deliver just as much sulfur per gram as a meat-based diet

What’s more, this theory is unsupported by science. In fact, studies published in several leading scientific journals, including The American Journal of Clinical Nutrition and Nutrition Today, discount the idea that vegetarian proteins are better for bone health than animal ones. 

Rather, research suggests the best course of action for your bones is to get a balance of both animal and vegetarian proteins! 

For example, a recent study followed 74,443 women and 35,438 men aged 50 and older for up to 32 years… and they found no evidence that higher animal protein intake increased hip fracture risk. On the contrary, plant and dairy protein were associated with significantly lower risk of hip fractures when results for both men and women were combined. 

This study shows the benefits of both animal and vegetarian proteins. And it’s only logical your body needs a balance of both. That way, you get all the essential amino acids, and the minerals and vitamins you need for strong bones!

AlgaeCal Plus provides all 13 minerals and three vitamins your bones crave in one convenient supplement. To learn more about this clinically-supported, bone-building supplement click here.

Protein and Bone Health Takeaways

Don’t shy away from protein.

Protein is a crucial component of every cell in your body. You need it to repair and build tissues, and it’s a key building block for cartilage, blood, skin, muscles, and bones. In fact, the latest expert consensus stresses the importance of protein for strong, healthy bones! 

Don’t be afraid of animal protein either. After all, the acid-ash hypothesis is unsupported by science, so including high-quality animal protein as part of a balanced diet won’t hurt your bones.   

But no matter your diet or lifestyle, there are plenty of protein options for you! Just remember to think about what you don’t want from protein too… 

Pesticides, herbicides, hormones, antibiotics, and preservatives won’t benefit you or your bones. So make sure you choose high-quality, organic, grass-fed, and wild-caught options whenever possible.

What a comprehensive and informative article- Thank you! I have been vegan for a long time and now am questioning/blaming… that lifestyle for my osteoporosis ( I’m 55, very active and THOUGHT I was taking care of my body…) What is the protein-calcium ratio for bone support? I started a little over a month ago taking Algae Cal and already see an improvement in my nails…..

Hi Kaden,

Thank you for reaching out – we’re so glad you found this article informative!

The recommended calcium intake for adults is 1000-1200 mg per day. AlgaeCal provides 720 mg of calcium and additional vitamins and minerals which help in the absorption and direction of calcium. We also take into consideration that people will be getting about 500 mg of calcium from their diet – this means that you’re reaching the recommended amount of calcium all through natural sources!  

Protein consumption needs can vary from person to person. However, as stated in the article, “recent research recommends older adults consume 1-1.5 g of protein per kg of body weight.” Feel free to use the formula above to calculate how much protein you should be consuming!

Hope that helps! Let us know if you have further questions 😊

I read with great interest your comments and studies on consuming to much protein. I’ve been concerned regarding this issue, and with your studies have decided to add more proteins into my diet.
I have a question which I haven’t seen addressed.
When striving to strenthen our bones, how does ones sleep patterns figure into the process? Should we be trying to get 8 hours sleep, is 6 hours sleep a night enough to be building our bones?

Megan AlgaeCal
Megan AlgaeCal

Hi Janice!

We’re happy to hear that you found our article on protein helpful. With regards to sleep, it’s definitely important to be getting a good night’s rest. A recent study found that postmenopausal women who slept less than 5 hours a night had lower bone mineral density compared to women sleeping 7 hours a night. So it may be a good idea to aim for more than 5 hours, and closer to 7 hours of sleep per night! 🙂

I have recently been diagnosed with low bone density. I started weight training with a trainer, stopped drinking sodas, limiting sugar and salt in my diet and I’m taking a calcium supplement with Vitamin D every day. My goal is to stay off the bone medicine which my doctor recommends. How long should I wait before I have another Dexa scan?

Jenna AlgaeCal
Jenna AlgaeCal

We’re so glad you reached out, Trisha!

Based on our human clinical studies, measurable results on a DXA scan can be seen in as little as 6 months time when taking our Bone Builder Pack (AlgaeCal Plus & Strontium Boost). That said, AlgaeCal is unique in that it’s the only calcium supplement with clinical trials showing it can increase bone mineral density – all other calciums have only been able to slow down bone loss. For this reason, we aren’t able to provide a time frame on when you might see results with other products.

If you have any questions we encourage you to give our Bone Health Consultants a call at 1-800-820-0184!

Your message is very informative. What can you say about the food supplement that contains high amino acids in combinations in a tablet form can this replace the food we eat on daily basis? My daily breakfast is one hard boiled egg a slice of grass feed butter(Kerrygold) spread over 2 slices of toasted white bread; half a teaspoon of dark chocolate(cacao)powder; 1/2 tsp. virgin coconut oil cold expressed; 2 tbsp. of garlic extract & tea-bag of Japanese green tea in a beer-mug size cup of hot water.(the garlic juice comes from 3 bulbs of garlic(skin-out) into a blender set at liquid with a beer-mug size of water and set it up at room tempt.. until it turns greenish-blue(the color is due to sulphur) and take 2 tbsp. of this extract that passes thru a sieve. Keep refrigerated & sake it on use for the extract settles at the bottom of the jar. Thank you again for sharing such good food info.

Hi Rosalinda,

So great to hear you find our content informative! While amino acids can be beneficial when incorporated into your daily regimen, there is no replacement for a healthy and varied diet.

If you’re looking to refine your diet and supplementation for the best benefit, we’d suggest working with a naturopathic doctor or holistic nutritionist who can consider your unique needs 🙂
