Life Extension Super K, Vitamin K Supplement, 2000 Mcg Vitamin K and 1180 Mcg Vitamin K2, Heart Health, Once-Daily, 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.

I like Life Extension products. I use the Super as well as other products. The quality is good and I am satisfied with the pricing.

It has both K's ..great stuff

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.

Great brand

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.

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

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 .
