Peak PerformanceAdvanced Vitamin D 5000 IU with All 3 Types of Vitamin K Vitamin D3 and Vitamin K2, K1, MK-7 (MK7), MK4 Supplement. 60 Small and Easy to Swallow Vegetable Pills (5000 IU)

I take this particular vitamin D3 regularly and just got tested, my numbers were within range. That’s enough reason for me to continue taking this brand.

Great for those who live in ohio and never see the sun

No sun D up

I decided to try this product because the price is very affordable, and it seems like they use high-quality ingredients. The packaging is also nice,and capsule size is tiny easy to swallow. So far, I’m impressed with the value for money. I will update this review after using it for a longer period to see how effective it is.

My labs came back and it showed that I was vitamin D deficient. I started taking this product and now my levels are normal. Clean ingredients. One tiny pill a day that's super easy to swallow. No smell. A VERY faint taste of black pepper. No stomach upset/irritation. Effective and Great value for money. I do recommend!

My psychiatrist recommended additional Vitamin D to help with my energy levels, and this stuff does the trick. The other vitamins are a good bonus too. No issues here, can recommend!

My doctor had been on my case for over a year about my low vitamin D levels. As a result I was taking some of the gummy D vitamins - at least several times a week. But my numbers really didn’t go up much. Since I have lab work coming up again, I thought I would try a “better” vitamin so I bought these. Never tried them before. Well I have no lab results yet but after being on these capsules for about a month, I really am feeling and seeing a difference. My skin was really acting up before - very dry and some dermatitis in places. My hair was getting thinner and thinner and my nails were looking yellow and brittle. Also I was always feeling tired. And my lower back had been really hurting for about a year despite ongoing Physical Therapy, massage and chiro at various intervals. I also saw an ortho doctor for my back and took various muscle relaxers and steroids to get it “under control” at the worst points. I even bought a very expensive new mattress that didnt help much. All of these symptoms seem to be better now that I am taking this D capsule. I don’t think this could be a placebo effect. It’s all very noticeably better now. The most surprising is my back. It didn’t happen overnight and I didn’t see these results with the other meds. Was I that low on D that it was really messing me up - maybe so....

Great product. Been using it for a year I take 1 daily with a miss here and there. Just got blood work done. Here in the east coast we are well into our cold months with limited sunlight and my Vitamin D levels are in optimal range. This product keeps my levels where they’re supposed to be and is very affordable. Also has the ideal vitamin D to K2 ratio. I highly recommend!
