Stability of vitamin K2 (K2VITAL®)
Vitamin K2 appears to be a very sensitive substance. Particularly in combination with calcium and/or magnesium, the activity of this vitamin in a tablet or capsule can decrease rapidly. Using vitamin K2 in a product with calcium and/or magnesium is certainly technically challenging. That is why Free Choice uses a high-quality K2 ingredient with the brand name K2Vital Delta, which is even 100% stable in a formula with a lot of calcium and/or magnesium.
