Perfect size vitamin

For the mere fact that these vitamin tabs serve dual purposes for k2 and d12 vitamins in an easily congested tab is great for people who have a vitamin regimen. It has no particular flavor, and is something id buy to keep my health going strong in 2025

Vitamin K2 and D3 easy to take softgels

Just started taking this a little over a month ago so I'm hopeful this will bump up my D3 its been low recewntly. Vitamins have become a daily regimen for me and make a difference after age 50. Sam's Club has a good variety and pricing on most of their vitamins. Pleased with it so far.

Vitamin D

My vitamin D level was low so I started taking this product and at my next physical my level was where it needed to be.

Good quality and price

I read that most people are deficient on vitamin k. So this product is perfect to try. I’ve only been using it for few days so I haven’t felt any noticeable difference. I’m having a physical soon and am curious what the blood work says.

Amazing!

Gave this to my mother-in-law and she loved it! And finding something that she likes is rare! She has bone density problems and although we haven’t gotten a test done again, I see a visible difference in the way she feels.

K2 is For You!

Great item! Taking K2 D3 combination is very important for bone health whereas just taking the D3 doesn’t help as much. The K2 helps deliver the D3 to the bones

Vitamin d meds that my son says give him energy!!!

I got these for me and my son. I have been taking them and don’t notice much of a difference but i am not as religious of taking them as my son. My son said he really likes them because they give him more energy and he feels better!

Vitamin K2+D3

Members mark vitamin K2+D3 I gave these to my husband to try and although he says he doesn’t see a difference I can tell he has more energy since taking these! Pros: -small softgels -no strange aftertaste -good value at 150 servings per bottle Cons: -bottle could be smaller due to the small size of the softgels doesn’t look full upon arrival -bottle opening in my opinion is too large So overall this is a good product but I think the packaging could definitely improve upon arrival the bottle is only about a quarter full seems like a smaller bottle would be better and the opening at the top of the bottle is quite large compared to the size of the soft gel perhaps a screw on lid without an opening would be better! My husband didn’t experience any side effects from taking this and hasn’t complained about any aftertaste… all In all I’d recommend this product I just think the packaging could use some revamping!

Vitamin

I have been struggling to keep my vitamin D elevated for the past several years and have been consulting my pcp about it to monitor the levels. This bulk bottle of high dose vitamin D is convenient and what my doctor recommended for me. I look forward to feeling better as time goes on.
