AlgaeCal Plus is a plant-based “superfood” calcium source naturally containing all 13 known essential bone supporting minerals (calcium, magnesium, boron, copper, manganese, silicon (silica), nickel, selenium, strontium, phosphorus, potassium, vanadium and zinc).

The marine algae naturally digests these minerals right from the ocean, in amounts similar to your bone’s composition. Magnesium, vitamins D3, C and K2, and boron are all added to the organic, milled powder in proper amounts to complete the multi-nutrient complex needed to nourish your bones.

Together, all these vitamins and minerals are clinically supported to maintain and improve bone mineral density.

How can this be? Continue reading below to better understand each ingredient and the role they play in bone health:

Lithothamnion superpositum (AlgaeCal)

The superfood calcium source making up AlgaeCal Plus is a rare marine algae called Lithothamnion superpositum (known to locals as Algas Calcareas). Algas Calcareas (or “AlgaeCal” for short) is a raw, kiwi-sized ball of algae found off pristine shorelines of South America. This unique algae species has a wide-range of uses– even as a healthy feed for the native livestock!

You may know calcium is the most plentiful mineral in your body. And 99% of all that calcium is found in your bones and teeth. But calcium does more than maintaining the very structure supporting your body.

Calcium helps muscles and blood vessels contract, enzymes and hormones secrete, and messengers pass through the nervous system. It helps our blood clot when needed, our heart pump, and helps nutrients move through the body. Without calcium, your body would literally stop functioning!

Naturally, we wanted to find an organic, plant-based calcium source that would not only provide all these benefits but would agree with our customers’ digestive systems. (Plus, not cause any side-effects like most traditional calcium supplements.) And that’s why we chose AlgaeCal.

Vitamin D

You probably know Vitamin D is an important ingredient for bone health. But like all the nutrients in this article, it’s responsible for a lot more than just strong bones.

Vitamin D has many effects on the immune system, keeping you healthy and protected from autoimmunity (where your immune system attacks your body, unprovoked).

What’s more, vitamin D promotes extra insulin secretion in times when insulin is required. Adequate vitamin D levels also may be responsible for decreasing high blood pressure.

According to the National Institutes of Health, vitamin D may play a positive role in battling osteoporosis, cancer and Alzheimer’s disease.

And of course, vitamin D is critical in calcium absorption and maintenance in the body.

The Relationship Between Calcium and Vitamin D

Calcium and vitamin D have proven that together they can drastically improve the absorption of critical nutrients in the bones. You’ve probably known that for years. But what you may not know is vitamin D and calcium pair up to do other helpful things in our body.

In fact, several recent studies prove vitamin D and calcium are connected with weight loss. The thinking is menopausal and postmenopausal women may be able to reduce weight gain because the two nutrients affect how the body breaks down and stores fat.

What’s more, two major studies in recent years show convincing evidence that increased calcium and vitamin D levels can reduce the risk of cancer. While these nutrients alone aren’t enough to ward off the disease, they can be helpful in treatment. Read more about these two studies that discuss calcium and vitamin D’s connection with cancer.

Additionally, vitamin D and calcium may lower the risk of type 2 diabetes in prediabetics as well. According to Dr. Anastassios Pittas of Tufts University School of Medicine in Boston, “Vitamin D and calcium may have direct effects on the pancreatic beta cells to enhance insulin secretion. “There may also be beneficial effects on insulin resistance, but the mechanisms are not clear.

Boron is actually a naturally-occurring carbohydrate in many fruits and vegetables. Often referred to as the “boron vitamin”, this trace element is shown to promote healthy bones and joints.

More recently, boron is thought to promote Vitamin D metabolism, improve prostate health and regulate steroid hormone levels.

Specifically relating to the bone, boron helps retain healthy calcium and magnesium levels. And that’s an important reason why boron helps maintain bone mineral density.

Magnesium is another “partner nutrient” of calcium. The two complement one another, as too little magnesium can interrupt calcium metabolism. Magnesium is also key in managing the hormones that regulate calcium.

In this way, magnesium deficiency may be a risk factor for developing osteoporosis. But- like all the vitamins and minerals on this list- magnesium’s effects are more than bone-deep. In fact, did you know magnesium is responsible for over 300 biochemical reactions in your body? It’s true.

As a quick list, magnesium helps muscle and nerve function … blood pressure and sugar levels … energy metabolism … steady heart rhythm … bone density, and many other things.

All this points to why magnesium plays important roles in diabetes, cardiovascular health, and bone health. (It’s also why we’ve included the maximum daily amount of magnesium in AlgaeCal Plus.)

Vitamin K2

Vitamin K2 (the MK-7 form) is the world’s most expensive vitamin. At $218,000/lb, it’s easy to see why.

But AlgaeCal Plus has a full daily dose of vitamin K2-7. What’s so special about this vitamin? Well, think of vitamin K2-7 like a “recycling plant” for the calcium coming into your body.

When calcium is deposited in the body, vitamin K2-7 comes along and transports it in proper amounts, to the proper areas. For instance, K2-7 directs calcium into the bones where it’s needed, and away from soft tissues it’s prone to collect, like your arteries and kidneys.

In this way, it’s also a positive ingredient for improved cardiovascular health too.

You can learn more about vitamin K2- like where to find it and how much you should take- at the link below:

Vitamin C

Vitamin C is an important antioxidant with several crucial roles in our body. And since it’s found in AlgaeCal Plus, it’s naturally shown to influence bone health.

Specifically, vitamin C helps trabecular bone building (the spongy, interior part) by promoting bone expression genes in our osteoblasts– they’re the specialized cells that build bone! In fact, recent studies show a vital link between vitamin C and bone genetics, with vitamin C playing a positive role in bone development.

You may know vitamin C is critical to maintaining a healthy immune system. But did you know it quite literally helps keep our body from falling apart? Vitamin C helps collagen synthesis, and collagen is a key ingredient in the connective tissues throughout your body. (Collagen also helps your wound healing too.)

When you add protein synthesis to this list, you’ll see just how important vitamin C is not only to your bones but to everyday function!

Trace Minerals

You know about calcium. You know about magnesium. And now you know about boron too. But did you know there are another 10 minerals your bones must absorb to stay dense and strong?

That’s 13 minerals in total making up your bone mineralization. And while there are minuscule amounts of the other 10 minerals in your bone (called trace minerals), that doesn’t mean they aren’t important.

In fact, lacking any number of these can lead to lowered bone density. And when your bones lose an average of 1% mineral density each year after age 40, they take the 13 minerals with them.

(It’s little wonder then that a calcium supplement with just calcium and vitamin D can’t increase bone density as time passes.)

So, short of purchasing all 13 minerals to maintain and improve bone density, what can you do to get enough of them? Well, you could try putting together the perfect meal plan that might just give you enough.

Or, you can take AlgaeCal Plus. Remember, this plant-based, whole food calcium naturally contains all 13 minerals in proper proportions (plus, added vitamin K2, D3, C, and boron). In fact, the marine algae in AlgaeCal Plus pre-digests these minerals in very similar amounts as those in your bones.

That’s why AlgaeCal recommends a multi-nutrient approach to bone-building. Any one-, two-, or even 12-ingredient combination won’t provide you the proper nutrition for your bones.

Strontium is another natural, earth element found in trace amounts in your bones. But strontium has a bone-health “claim to fame” that other minerals don’t.

You see, strontium is the only known mineral to have a dual effect on bone. While strontium can increase the amount of healthy new bone you build, at the same time it naturally slows down bone loss!

Taking the proper amounts of natural strontium is like turning back the clock on bone density loss. But notice I said “natural” strontium. That’s because there are man-made forms of strontium that aren’t effective in this way– and cause a host of adverse side effects. Read all about strontium, its various forms, and the natural form’s positive effect on bone health in our comprehensive strontium guide.

But for now, just know that natural strontium citrate- taken together with AlgaeCal Plus- is the reason we can guarantee increased bone density in 180 days. That’s thanks to Strontium’s dual effect in natural bone remodeling.

Now, AlgaeCal Plus already contains trace amounts of natural strontium. And that’s good for your bones. But it takes higher doses of strontium to really kick-start bone building. That’s where Strontium Boost comes in. When combined with AlgaeCal Plus, the natural strontium inside Strontium Boost makes the whole food calcium work better, and faster.

There you have it. You’ve just seen the full ingredients list behind the only calcium supplement that can increase bone density, no matter your age. Thanks to the 13 naturally-occurring minerals in our protected ocean algae- and the added vitamins- your bones absolutely can return to youthful density.

With AlgaeCal plant calcium, there are no secret ingredients or unsubstantiated claims– just natural goodness with real results. After all, nature knows best.
