Fat isn’t your body’s public enemy #1 like you were taught it is.
Sure, the unhealthy trans fats in processed foods are definitely on the “foods to avoid list.” After all, they cause cardiovascular disease and obesity. But not all fat is out to get you.
In fact, some fats are actually out to help you…
They might not get the same level of attention as the bad fats, but omega 3 fatty acids work wonders for your entire body. You may have heard that omega 3 fatty acids can help reduce your risk of cardiovascular disease, ease the pain in aching joints, and protect your brain against age-associated cognitive decline. Not a bad resume, right? But it gets a whole lot better.
Omega 3 fatty acids also play a key role in your bone health and may even help protect you from osteoporosis! So, if you lack omega 3 fatty acids, you’re missing out on a whole host of health benefits.
I’ll cover how omega 3 fatty acids can help protect you from osteoporosis in just a moment. But first, let’s take a step back and look at essential fatty acids in a slightly broader sense.
What Are Essential Fatty Acids?
You need fats to keep functions from your brain to your toes running smoothly. And different functions need different fats.
Your body can make some of these fats itself, but not all of them. So you need to give your body a helping hand by providing them via your diet. These are called essential fatty acids. And the omega 3s are one of these essential fatty acids.
The History of Omega 3s and Omega 6s
The Husband-and-Wife Team Discovery
The husband-and-wife team of George and Mildred Burr discovered essential fatty acids in 1929. But the discovery wasn’t what they intended…
The Burr’s were initially trying to show that vitamin E is vital for reproduction, by feeding a group of rats a vitamin E-free diet. But the rats in their study were not always sterile. So the Burr’s came to the conclusion that some of the fat in the rats diet must be providing some vitamin E.
In the next stage of their research, the Burr’s removed all fat from their rats’ diet too. But they stumbled upon a whole new discovery…
After several months without dietary fat, the Burr’s rats developed scaly skin, their tails became inflamed, their paws reddened, and their fur was full of dandruff. The animal’s fur fell out soon after, they lost weight, and eventually, they died. George and Mildred concluded that fat is an essential part of diet for the maintenance of normal physiological function and the prevention of disease… Not just a source of energy as was previously thought.
George and Mildred weren’t finished there though! They wanted to unearth exactly what it was about dietary fats that’s so vital. The Burr’s continued their research and published another paper in 1930. They proposed that only one fat could be missing from the diet that the body could not make itself– linoleic acid. The Burr’s described linoleic acid as an essential fatty acid, and the term was born!
Essential Fatty Acids As We Know Them Today
George and Mildred Burr’s discovery was groundbreaking. But their proposal that linoleic acid is the only essential fatty acid was incorrect. In fact, George himself was part of the team that discovered alpha-linolenic acid is also an essential fatty acid.
And so the foundation of what we know about essential fatty acids (and their effects on bone) was laid. Since George and Mildred’s discoveries, research has uncovered the link between alpha-linolenic acid and linoleic acid and the omega 3 and 6 fatty acids:
The Omega 3 Fatty Acids
We now know that George’s second discovery– alpha-linolenic acid –is actually a “parent” omega 3. See, alpha-linolenic acid produces two “offspring” omega 3 fatty acids:
- Eicosapentaenoic acid (EPA)
- Docosahexaenoic acid (DHA)
It’s these two omega 3 fatty acids that provide you with the numerous health benefits I outlined at the start of this post. AND, they can help protect you from osteoporosis too.
How? Well, EPA and DHA benefit your bones in a few ways. (I’ll go into more detail in the next few sections). But the most notable quality of these two omega 3 fatty acids is that they help protect you from inflammatory diseases. And that includes osteoporosis.
See, anything that promotes chronic, low-grade inflammation activates your osteoclast cells– specialized cells that break down your bones. EPA and DHA counter this inflammation in many ways. The main ones are:
- EPA and DHA compete for the same enzymes that the omega 6 fatty acids (more on those below) would use to produce pro-inflammatory compounds.
- EPA and DHA use these enzymes to produce anti-inflammatory compounds– the resolvins and protectins. The aptly named resolvins resolve the inflammatory process. And the protectins protect you from chronic inflammations’ harmful, bone-removing effects.
The Omega 6 Fatty Acids
Remember George and Mildred Burr’s first discovery- linoleic acid? Well, we now know that linoleic acid is an omega 6 fatty acid. It’s a “parent” essential fatty acid of arachidonic acid.
Now, the omega 6 fatty acids play an important role in your health too, and have protective effects of their own. But get this; if your levels of omega 3s and omega 6s are unbalanced, the omega 6s can actually cause bone loss! See, omega 6 fatty acids, like arachidonic acid, produce inflammatory compounds. The exact opposite of omega 3 fatty acids!
So your levels of omega 3 fatty acids and omega 6 fatty acids need to be in balance, or there will be an overload of pro-inflammatory compounds which will cause bone loss.
How Omega 3 Fatty Acids Protect Your Bones From Inflammation
As I mentioned in the last section, anything that causes inflammation activates osteoclasts, the specialized cells that break down your bone.
Now, foods containing pro-inflammatory fats (like too much of the omega 6s), environmental toxins, and certain diseases can all cause inflammation in your body. You can check out our “Top Causes of Osteoporosis” page for more information on each of these categories. They all cause inflammatory signals to tell your bone removing osteoclast cells it’s time to get to work.
Your osteoclasts are only supposed to remove old and brittle or damaged bone. A job they do very quickly. Then, they’re supposed to clear out and let the bone-building osteoblast cells start the more time-consuming job of rebuilding new bone to replace the bone your osteoclasts have removed.
But when inflammation is chronic, your osteoclasts go into overtime. Since building new bone takes much longer than breaking down old bone, too much osteoclast activity can result in bone thinning (or osteopenia) and, ultimately, in osteoporosis. That’s where the omega 3 fatty acids come in.
EPA and DHA tune down the inflammatory signalling that causes your osteoclast cells to activate. This effectively sends the osteoclasts home and prevents excessive bone loss.
What’s more, EPA and DHA increase the production of the bone-building osteoblast cells, invite them in and give them enough time to lay down new bone.
It all sounds quite straightforward, but in reality, the process is very complex.
We now know that an intricate dance is constantly occurring within our bodies that enables inflammatory signals to be sent when needed and shut down when further inflammation could cause harm. Both types of essential fatty acids – the omega 3s and the omega 6s – are partners in this inflammation-regulating dance. When they move together in balance, damaged bone is removed while new bone is continuously built.
But when omega 3 isn’t available to partner omega 6 in this dance, the inflammatory side of omega 6 spins out of control. Osteoclasts go on overtime. Osteoblast production and activity is inhibited, and you lose bone.
The bottom line is that it’s all about balance. And I’ll tell you the exact ratio of omega 3s and omega 6s you should aim for– plus where to get them from– in just a moment. But first, there’s a beneficial side effect of the omega 3s inflammation fighting …
Omega 3 Fatty Acids Help You Build Bone Instead of Fat
As we’ve discussed, the omega 3s encourage the production of osteoblasts– the special cells that build bone. Here’s how it works…
In your bone marrow, you have cells called mesenchymal stem cells (MSCs.) MSCs can become osteoblasts, or they can become adipocytes, which are fat cells. Obviously, you’d prefer healthy bones to unhealthy amounts of fat.
But what makes your MSCs become osteoblasts or adipocytes? That’s where the omega 3s and omega 6s come in.
MSCs are influenced by the compounds derived from both omega 6 (linoleic acid [LA]) and the omega 3 (alpha-linolenic acid [ALA]) fatty acids.
Remember, LA (omega 6) and ALA (omega 3) are the “parent” compounds all the essential fatty acid “children” are derived from. The “offspring” of LA convince MSCs to become fat cells, while those of ALA convince them to become osteoblasts.
The first compound produced from omega 6, arachidonic acid (AA) is rarely a friend to your bones! See, AA promotes bone resorption in several ways:
- AA “suggests” to MSCs that they become fat cells, which results in fewer MSCs becoming osteoblasts
- If some MSCs still try to become osteoblasts, AA throws up roadblocks that make it really hard for them to do it
- AA is very pro-inflammatory. It lowers the production of an anti-inflammatory compound called osteoprotegerin (OPG), which is produced by mature bone-building osteoblasts
OPG looks just like another, but very pro-inflammatory, compound called RANK (receptor activator of nuclear factor-kappa B). For RANK to become active, it has to be turned on by another compound called RANKL, which stands for the RANK ligand. When RANKL binds to RANK, this sets off a whole series of inflammatory events that results in the production of osteoclasts ready to remove bone.
But the good news is that when RANKL binds to OPG instead of RANK, no inflammatory signals get sent, and no osteoclasts get produced.
It’s important to note here though, that you do want to have some RANKL to RANK binding. You need osteoclasts to remove old brittle bone, so there’s room for new, healthy bone to be laid down to replace it.
And, RANKL’s binding to RANK is also necessary for the activation of immune cells (your T and B cells, specifically). You must have functional immune systems to survive after all. What good are great bones if you’re easy prey for destruction by infections or cancer?
Again, the key here is BALANCE. The nifty way our body has worked out this balancing act among RANKL, RANK, and OPG is just one example.
In contrast to the parent omega-6, linoleic acid, and its offspring, (AA), the parent omega 3, alpha-linolenic acid, and its offspring, EPA and DHA, combat inflammation.
The omega 3s inhibit the production of osteoclasts, and this slows the rate of bone removal. Plus, the omega 3s encourage MSCs to become osteoblasts, increasing the number of the cells that build new bone, and reducing the amount of fat cells. It’s a win-win!
Omega 3 Fatty Acids and Bone Density- The Studies
One of the most recent studies on the relationship between omega 3 fatty acids and bone health involved 117 healthy, postmenopausal women.
The women were allocated to one of two groups:
- The intervention group – The women in this group consumed 0.5 liters a day of a low-lactose skimmed milk enriched with 40 mg (100 ml) of EPA and DHA and 0.54 g (100 ml) oleic acid– an omega 9 fatty acid.
- The control group – The women in this group consumed 0.5 liters a day of a semi-skimmed milk enriched with just vitamins A and D.
After 12 months, the intervention group saw a 5.78% decrease in total cholesterol, while the control group saw no change.
That’s encouraging news for cardiovascular risk, but here are the important findings as far as bones were concerned…
The intervention group saw a 28.20% decrease in C-reactive protein (a marker for inflammation), and a 17.64% decrease in RANKL– remember, when RANKL binds to RANK, it sets off a chain of inflammatory processes which results in more osteoclast activity and bone loss!
Another recent study focused on the relationship between omega 3 fatty acids and bone density in 1,865 Spanish women aged 20 to 79.
Each woman underwent a dual-energy X-ray absorptiometry (DEXA) to measure their bone mineral density (BMD). One hundred and ninety four women had osteoporosis, 707 had osteopenia, and 964 had a normal bone density.
In addition, each woman recorded her dietary intake of calcium, vitamin D, the omega 3s (ALA, EPA, and DHA) and the omega 6s (LA and arachidonic acid) in a food journal.
The study found that women with a normal bone density consumed more EPA and DHA combined than the women who had osteopenia or osteoporosis. Plus, the women who had osteopenia consumed more EPA and DHA combined than the women who had osteoporosis.
Now, the researchers couldn’t pinpoint EPA and DHA intake as “significantly correlated” with BMD in the women with osteoporosis. Their calcium and vitamin D intake, their age, and their menopausal status (post-menopausal women lose much more bone each year than premenopausal women) all are variables that could contribute to their low BMD. Still, the fact that the women with osteoporosis generally consumed less EPA and DHA is telling.
But, the researchers did conclude that omega 3 fatty acid intake was “significantly associated” with BMD at both the hip and the lumbar spine in women with a normal bone density and women with osteopenia.
Are You Getting Enough Omega 3s?
There’s currently no universal recommendation for the daily intake of EPA and DHA. But current research shows you gain the optimal health benefits of omega 3 fatty acids when you consume 2.6 to 3 grams combined of EPA and DHA a day.
And remember, optimal bone health requires a balance of omega 6s and omega 3s. You want to make sure your ratio of omega 6 to omega 3 intake is no more than 4:1. Ideally, the ratio would be more like 2:1! So keep your intake of omega 6s (think processed vegetable oils like corn, canola, and soy) in check.
The top sources of EPA and DHA are predominantly seafoods, especially oily fish. Refer to the table below to see which seafood contains the most:
|Type Of Fish||Grams of EPA + DHA in 3 ounces|
|Trout (freshwater, wild)||3.0|
|Mackerel (N. Atlantic)||2.5|
|Anchovies (European, canned in oil)||1.7|
|Salmon (Wild, Chinook)||1.4|
|Salmon (Wild, Sockeye)||1.2|
|Salmon (Wild, Canned)||1.0|
|Crab (Alaska king)||0.4|
|Oyster (Eastern, Farmed)||0.4|
Can you see why it’s difficult to achieve the optimal recommended intake of 2.6 to 3 grams of EPA and DHA a day? Unless you’re eating trout or North Atlantic Mackerel every day, you’d need at least two 3 oz servings of the other top sources… Every day! That’s a lot of fish, even if you love seafood! Not to mention how much that amount of fish would add to the weekly grocery bill…
That’s why omega 3 supplements, like Triple Power Omega 3 Fish Oil, are a more convenient, realistic way to meet your daily needs.
Triple Power Omega 3 Fish Oil provides 1200 mg of EPA and DHA combined in every tablespoon. (There are 1000 milligrams in a gram, so a couple tablespoons of Triple Power a day and you’ll be well on your way to that optimal recommended intake of 2.6 to 3 grams).
And remember the high level of mercury in many fish I mentioned earlier? Well, Triple Power only uses fresh, wild anchovies, sardines, and mackerel from small, local fisheries in the Pacific. These fish already contain a very low level of contaminants like mercury. But to be on the safe side, Triple Power is molecularly distilled to produce a pure, ultra-refined oil with virtually no contaminants. It’s a safe, effective way to get your omega 3s.
What’s more, Triple Power provides a further 280 mg of other omega 3 fatty acids. Plus astaxanthin and curcumin; two of the most powerful anti-inflammatories on the planet! Remember, chronic inflammation activates your bone-resorbing osteoclast cells.
Triple Power is a liquid emulsion too. That means the anti-inflammatory curcumin and astaxanthin are better absorbed. And, it can be flavored. Triple Power’s mango flavor is truly delicious. No nasty fishy burps with Triple Power! I actually like to drizzle my Triple Power over my morning granola, but I’m always on the lookout for new uses, so please let me know how you use yours in the comments section.

Animal vs Plant-Based Omega 3s
Remember the “parent” omega 3 fatty acid– alpha-linolenic acid? It’s important we clear up a common misconception about it…
Alpha-linolenic acid (ALA) is an important omega 3 fatty acid in its own right. But it’s not a suitable substitution for EPA and DHA. It just won’t provide you with the same bone-protecting benefits.
You get EPA and DHA from animal sources, like the table of seafood above. But ALA is primarily a plant-based omega 3. You can find ALA in:
- Brussel sprouts
- Chia seeds
- Pumpkin seeds
- Free-range chicken eggs
Many people think these plant-based omega 3 sources will fulfill their EPA and DHA needs because they contain ALA, and ALA can be converted to EPA and DHA. While it’s true your body uses alpha-linolenic acid to produce EPA and DHA, you only convert a very small amount.
In fact, studies show humans who eat a diet high in saturated fat convert as little as 6% of dietary ALA to EPA. And just 3.8% of ALA is converted to DHA. A diet high in omega-6 rich vegetable oils inhibits ALA’s conversion to EPA and DHA further. Research shows the conversion of ALA to EPA and DHA is reduced by 40% to 50% in such diets!
The bottom line: You should include plant-based omega 3 sources in your diet. But you need to make sure you include EPA and DHA specific sources (like seafood and Triple Power Omega 3 Fish Oil) too.
You may have heard of other health benefits of omega 3 fatty acids before. They reduce your risk of cardiovascular disease, ease the pain in aching joints, and protect your brain from age-related diseases. But now you know omega 3s play an important role in your bone health too!
EPA and DHA are the two omega 3s that provide the most benefit to your health and bones. Oily fish like mackerel and anchovies provide the most EPA and DHA. But to reach the optimal recommended daily intake of 2.6 to 3 grams you’d have to eat a lot of fish!
That’s why a fish oil supplement like Triple Power Omega 3 Fish Oil is the most convenient, realistic way to reach your daily target. Triple Power contains a combined 1200 mg of EPA and DHA. And it tastes absolutely delightful!
