DM –
Very good vitamin D
I take a lot of supplements and never know if some of them make a difference. I feel like this is one that makes a difference. 2 weeks in and I feel like this helps me think more clearly. Love this brand and will stick with their vitamin D.
Aaron –
Very good vitamin D supplement from Biotest
I take one capsule daily and this brought my low vitamin D level up to 35.6 ng/mL. I know this could be higher but I was <20ng/mL when I was originally tested. I'm going to continue with this vitamin D supplement and see if my levels go even higher.
Yohanne –
Great source to get your Vitamin D
My Vitamin D level check for my annual physical came in at 60. I took one AM and one PM. I started with one daily and had a 45 result. I went to the AM PM and achieved the 60.
Chad Bubak –
It sucks I could not try this.
Unfortunately I can only give this product 1 star because this is the second unusable bottle that has been shipped to me. Both separate bottles had the pills inside melted together rendering them unusable.

Excelente producto lo recomiendo
John C. Landry –
It’s tested
But the cheapest, but I’ve been reading about the cheaper brands possibly not being absorbed well by the body. I’m paying extra for the peace of mind that this has been tested for that attribute.
