Life Extension Super K, Vitamin K1, Vitamin K2 mk-7, Vitamin K2 mk-4, Heart Health, arterial Health, Calcium Balance, 3-Month Supply, Gluten-Free, 1 Daily, Non-GMO, 90 softgels

Local stores are not selling plain vitamin K. They are only selling combo Vitamin K3 + Vitamin D2. Vitamin D is produced by our skin if we go outdoors at all. Vitamin K is found in green leafy vegetables. Type MK7 works in the liver & bone marrow. Type MK1 works in the brain. Most Vitamin K supplements are only type MK7. They are small, easy to swallow, no side effects, no stomach upset, & a decent price. The quality appears to be good.

Great product

I wasn’t sure if it would work. I donate blood at the Red Cross and everytime I would go they would verify I didn’t take aspirin because I would not stop bleeding for a couple of minutes and I would always tell them I don’t use aspirin. So I bought the vitamin k1,2 because k1 is good for clotting. I took it for a week and I went to Donate. For the first time they but the band aid over the needle hole and that was that. It’s either a strange coincidence or this brand actually works.

It's a supplement, I have to assume it is helping get calcium into my bones. I have osteopenia, my last bone scan showed that I am the same, osteopenia, but it was noted that my lumbar spine appear to have a higher density than my scan 2 years earlier!! I also take 5000 Vit D and Citrical. I heard that they may allow hormone therapy again, I will check into that as osteoporosis isn't something I plan to deal with. The bad: I ordered this last in January 2025, ordered enough to get through the summer heat because reviews stated they melt into a clump during shipping. I paid just under $14 a bottle, they have OVER DOUBLED the price!!! Super unhappy with the high price of Super K.

I added these to my regiment and love the way I feel.

Un suplemento increíble no necesitas inyectarte con este producto recomendado

With vitamin K1 and two forms of vitamin K2, this one of the best ways to get your daily requirement of Vitamin K if your diet is lacking in it. Like most Life Extension products, this is Gluten-free, non-GMO, and manufactured in the USA. I will continue to be a customer!

Great value! Doctors forget to tell you tha you need to take vitamin K , if you are taking Vitamin D. I love that these are tiny gel caps.

good product, well priced.

I don't know how or when I will know if this is actually beneficial re the calcium absorbion !? Will try to monitor and hopefully update this accurately later . Hope I haven't left this to late as already have significant vascular issues .
