Too soon to tell

I have been taking this only a few days now and have not noticed anything yet. I feel I need to give it more time to see if it in fact works as it should. I will have to come back once it’s been a little longer to see/feel the benefits.

I like this overall. The only concern is the high level of Vitamin D3. This one has 5000 IU which could be too much for some people. I would really like if this was maybe half the dose. Unfortunately Sam's do not carry similar product in lower dose.

Good combo

If you’re looking to do a combination of 2 needed vitamins this is for you. It’s an easy to swallow, dye free caplet. It leaves no nasty aftertaste. After taking for a couple of weeks I noticed some hair growth and energy boost.

Vitamins

So far seems to be working. Have a little more energy. Have only been taking 2-3 week. Need to stay on it a little longer probably to get full effect of the vitamins. Need to stay on them daily to ensure work

I see the differences after taking this vitamins. Worth for the money and recommended. It is cheap comparing to other brand and that too combination of K2 and D2 vitamins..............................

High Level Vitamin D3 Supplement

After 7 months of daily use, blood work revealed I had toxic levels of Vitamin D… Users beware and talk to your PCP’s if this dosage is right for you.

I have been taking vitamin k for a few months now, because I've been having a lot of problems with my bones and calcium. My doctor was very pleased to see me taking vitamin k. Thank you Sams for carrying this vitamin and having it where I could afford. And it seems like it is helping me more and more each day.
