The packaging appears reliable—the tablets are neatly packaged, and the information is clear. Ingredients: 1 tablet contains vitamin K1 (1,820 mcg), vitamin K2 in both forms—MK-4 (200 mcg) and MK-7 (180 mcg), plus calcium (63 mg).

My Go-To Vitamin K1 & K2 Supplement
Verified Purchase
I have been taking Source Naturals Vitamin K2 Advantage for years. They are great quality. Ingredients include Vitamin K1 and both K2 MK4 and MK7 in adequate quantities. Tablet size is small and easy to swallow. Dosage is one a day. I buy the 120 tablet bottle. Tablets are smooth and have no taste. I credit my vitamin K and vitamin D supplements with keeping my cardiac arteries free of calcium deposits. My cardiac calcium score is zero. Can’t get a better benefit than that.

I am taking this to help with my bone health. I have osteoporosis. It will be a while until I can tell if it works.

Great
Verified Purchase
Fish oil is very beneficial and necessary for the health of the heart, skin, and hair. Omega 3 (ingredients, composition) is especially important for those who suffer from inflammation in the body. That's why my mother and I take this supplement in courses and also give it to our children. It's excellent quality.

A very comprehensive vitamin K supplement, containing not only K1 but also two different forms of K2, MK4 and MK7. In fact, if you learn more about the relevant knowledge, you will find that different types of vitamin K can actually play different roles in the body. Supplementing them as a combination is very scientific and brings great benefits to the body.

I take it in combination with vitamin D3. MK7 forms are best.
