As discussed earlier, Vitamin K2 cleans calcium deposits from your arteries and deposits it in your bones. The good news is Vitamin K2 has been clinically proven to provide extraordinary benefits for bone health and cardiovascular health, plus it is a powerful anti-oxidant and some emerging science indicates it might help your joints and intestinal health.

Usually, I recommend a D3/K2.  This is why one should not consider D2; Vitamin D2 is far less effective than Vitamin D3. It’s not absorbed well by the body, but “mainstream medicine” continues to treat Vitamins D2 and D3 interchangeably. This study from The American Journal of Clinical Nutrition couldn’t be more clear in its conclusion about the inferiority of Vitamin D2:

“Despite an emerging body of evidence suggesting several plausible explanations for the greater bioefficacy of vitamin D3, the form of vitamin D used in major preparations of prescriptions in North America is vitamin D2. … Vitamin D2, or ergocalciferol, should not be regarded as a nutrient suitable for supplementation or fortification.”

In the above study, it was revealed that D2 and D3 do not follow the same metabolic pathway as previously thought. In addition, D2 was shown to be quite unstable and prone to toxic contamination due to the way it’s manufactured. “Vitamin D2 is synthetically produced from irradiation of ergosterol derived from the mold ergot” the authors state in the study. In contrast, “vitamin D3 is manufactured in a similar manner to that which occurs naturally in human and animal skin.”

Regarding the source of K2 in Algae, the seaweed has over 72 other trace minerals and provides a bioactive calcium.

By getting calcium naturally from plants – rather than from limestone, the source of many calcium supplements – your body recognizes it immediately as a natural food and absorbs it better.  The plant-based calcium also has a porous honeycomb structure, which allows easier digestion and absorption by your body for the best result.

Consider the most natural plant based source for your vitamin intake. We recommend Thorne 3-K Complete. It helps maintain bone mineral density and supports healthy blood vessels, contains three clinically studied forms of vitamin K – vitamin K1, and two forms of vitamin K2 (MK-4 and MK-7). It also contains significantly more MK-4 than most other multiple-K products on the market.
