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

Worth and effective

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..............................

Vitamin K + D

They help with supporting heart, bone and immune system. The sizing of the vitamins is good. They aren’t big like some of the other vitamins I’ve taken in the past. I like that they are softgels. These vitamins don’t have any unappealing scent.

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.

Truly a life saver! Great product!

Have been taking this for a while! I am Deficient and I have to take this. This combo is the best to help your body absorb the vitamin D3! I feel so much better since I started taking these! Thank you Sam’s Club for giving us affordable supplements like this!

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.

Just need D3 - Go to Walmart

I bought this after looking for the 400-count 125 mg D3 that Sam’s usually has. This was the only product available in that dosage. Cost more than twice as much for 150 gel caps. Not so much a product issue as an availability issue. I returned this product after finding the larger and cheaper product at Walmart.

This mix didn’t work for me.

Yes, mix of vitamins did not work for me. Actually they only gave me headaches. I liked it when it was just vitamin D. Why can’t we just have a single supplement. BeCause for the last two visits to Sam’s they did not have the regular single vitamin D supplement on the shelf anymore. I think it still might be available for order. But who wants to go through that?
