AlgaeCal™ Research Summary

Changes in Total Body Bone Mineral Density Following a Common Bone Health Plan With Two Versions of a Bone Health Supplement: Comparative Effectiveness Research Study

This human study compared two AlgaeCal formulations (one of which is AlgaeCal Plus and Strontium Boost). More than 200 healthy people were involved in this study including men and women from age 18 to 85. The primary outcome measure was bone mineral density and a secondary measure was safety as reported in a panel of 43 blood tests along with quality of life questionnaire. AlgaeCal Plus and Strontium Supplement Boost group achieved an outright increase in bone density of more than 2%. Calcium studies often report an “increase in bone density”, but it is never an outright increase – it is an increase compared to the placebo group which is declining. This can be confusing, because although it is generally reported as an increase in bone density, the participants are actually losing bone. To be very clear, this AlgaeCal Plus and Strontium Boost study is a landmark result with a real increase in BMD. This study has been published in a prominent peer-reviewed journal Nutrition Journal – and in Pubmed –

A Comparative Effectiveness Study of Bone Density Changes in Women Following Three Bone Health Plans With the Same Novel Plant-sourced Calcium

This comparative effectiveness study involving post menopausal women compared three AlgaeCal formulas to published data on traditional calcium supplements BMD scores. Post menopausal women are expected to lose approximately 1% of bone density per year with traditional Calcium supplements only slowing that rate of loss slightly. This study shows each AlgaeCal group increasing bone density at one year.

This study has been published in the International Journal of Medical Sciences –

Comparative effects of a novel plant-based calcium supplement with two common calcium salts on proliferation and mineralization in human osteoblast cells

Researchers from the Harvard Medical School and University of Connecticut, collaborate on this landmark study which was accepted for publication in an upcoming issue of the peer-reviewed journal, Molecular and Cellular Biochemistry. In direct head-to-head tests, the scientists compared the effects of AlgaeCal with the two top-sellers, Calcium carbonate and Calcium citrate.

Focused on the proliferation, mineralization and oxidative stress in cultured human osteoblast cells, the study results showed that AlgaeCal®, increased alkaline phosphatase activity 200 percent more effectively than calcium carbonate and 250 percent better than Calcium citrate. In addition, AlgaeCal outperformed calcium carbonate and calcium citrate by 300 and 400 percent respectively on DNA synthesis – the ability of these osteoblasts to produce new bone building cells.

In other words, the AlgaeCal Calcium increased the number of human bone building cells by 400 percent more than calcium carbonate. The study findings provided evidence that AlgaeCal plant Calcium is superior to the two most popular forms of calcium in all test parameters – the first time in the history of Calcium research that a significant difference was shown between the many commercially available Calcium ingredients’ effect on bone cells.

Safety and Toxicological Evaluation of AlgaeCal, A Novel Plant-based Calcium

Six different safety studies have been conducted on AlgaeCal in the United States and Europe and combined into one manuscript which has been accepted for publication in the peer-reviewed journal, Toxicology Mechanisms and Actions.  These studies include one which tested the toxicity of AlgaeCal on pregnant and nursing females.

Plant source Calcium from Organic Wild Ocean Algae (Lithothamnium c.)

A Whole Food Calcium Source

Medical professionals agree the best source of nutrition is from foods rather than isolated elements. And Calcium is no exception – Calcium works much better together with all its co-factors and trace minerals. Now, for the first time in history, a Calcium complex from plants is available. Which would your customers  prefer – isolated calcium, or a symphony of nutrients in a natural balance?

Plant Versus Rock:   Your current Calcium supplement is either inorganic or laboratory-made. By far the most common form of Calcium in supplements is Calcium carbonate which is limestone – a rock. Which would your customers prefer – rock or plant?

Living Versus Dead:   AlgaeCal washes up on the pristine shores of South America where it is harvested live, just like vegetables from a garden, then cold processed to retain nutritional value.

Bio-available And Ionic: The porous nature of AlgaeCal dramatically increases the surface area where stomach acid can contact the calcium, making it easy to dissolve. Calcium must be completely dissolved in order to be absorbed, so this is an important first step. Dissolution tests mimicking stomach conditions show 97% of the calcium in AlgaeCal is dissolved in 30 minutes proving AlgaeCal is very bio-accessible!

AlgaeCal™ from a unique South American marine algae (Lithothamnium), is the first Calcium ingredient in the history of Calcium supplementation to show an increase in bone mineral density according to clinical studies.

Common Calcium supplements have been around for over 50 years. They are usually sourced from limestone, bone, coral, oyster or egg shell. But not one of them has been able to stand apart from the pack in anything other than bio-availability...except AlgaeCal

AlgaeCal™ has been studied for bioavailability, but also specifically to understand its effect on human bone building cells and bone mineral density (BMD), versus other Calciums.
