The Solgar Natural Vitamin K2 (MK-7) 100μg is a dietary supplement in plant capsules, with 100μg of vitamin K2 per capsule, an amount corresponding to 133% of the Recommended Daily Allowance. K2 is in its natural form of menaquinone-7, derived from natto, a traditional Japanese fermented food. The package contains 50 phytocapsules.
It is aimed at adults who want to cover their vitamin K intake with one capsule per day, often alongside a vitamin D supplement, and those who consume few fermented foods.
Vitamin K is not a single molecule but a family. K1 or phylloquinone comes from green leafy vegetables, while K2 or menaquinone has various subcategories differing in the length of their side chain, from MK-4 to MK-10. MK-7 has a long chain, which gives it a clearly longer circulation time compared to MK-4 and K1.
In the body, vitamin K acts as a cofactor of an enzyme that performs γ-carboxylation, a chemical modification of certain proteins. Without it, the so-called vitamin K-dependent proteins, including clotting factors and osteocalcin of bone tissue, cannot bind calcium. The MK-7 in the supplement is produced by fermentation, just as in natto, the dietary source with the highest concentration of MK-7 worldwide. It is a fat-soluble vitamin, so taking it with a meal matters.
According to the product presentation by Solgar, the vitamin K2 in this supplement is presented as follows:
The above statements are attributed to the producer, except for the two approved health claims of vitamin K, which are valid under Regulation (EC) 1924/2006.
With 100μg per capsule, i.e., 133% of the Nutritional Reference Value, the supplement comfortably covers the limit required to qualify for these claims. Attention, the formula contains soy and milk, which matters for anyone with a related allergy or intolerance.
It suits adults who take vitamin D and want to add K2 to the same protocol, one of the most common combinations in the pharmacy. It suits those who do not consume fermented foods like natto or certain mature cheeses, the main dietary sources of K2. It also suits older people interested in dietary support for their bones. This is a dietary supplement. It does not replace a medical diagnosis or treatment, and anyone monitored for bone density needs a doctor's evaluation.
