Great product, recommended by my Doctor.

I’ve been taking these for a few weeks now after sometimes with a vitamin d deficiency told me about the need to have vit k as well … glad I listened to her because I can feel the difference. I’ve always been either deficient or right at the low normal range, and think these will do the trick without needing a prescription potency one. Easy to swallow and no issues with my tummy.

The product is great and I don't like to run out of it. Glad to have it easily accessible from this seller.

Very effective

Highly recommend. After taking it consistently daily for a few months, I tested on the high end of the scale and was able to drop down to 2 days a week to maintain.

A lot of us take Vitamin D3. What most of us don't know is that Vitamin D3 can't be properly absorbed in your body without Vitamin K. If you need D3, you also need K.

The whole family takes these! My energy has really increased since being consistent!

The product came on time and is exactly as depicted. I use these capsules daily.
