D3-5 (5,000 IU)

I love this product!! Great company and easy to swallow. It keeps my Vitamin D levels within range of my blood work. I have been using for about 5 years. No side effects.

My daughter has to take these for her cf and we take 4 capsules once a week and they are really good! They are super tiny but I open the pill and just sprinkle it in her food!

I've tried prescription vitamin D and injections and I've stayed below normal D levels for YEARS. This is the first supplement that actually got me in the normal range because you don't have to take it with food! I take it at night with the rest of my pills and it works perfectly. No smell, no after taste, easy to swallow!

Arrived quickly and packaged with care.

I had a Duodenal Switch procedure 15 years ago. I had consistently run a vitamin D deficiency until trying this product. It has way more vitamin D then the product my physician had recommended, it's absorbed very well and it's a tiny capsule. Because of this, I was able to lower my calcium/vitamin D combo to 3 times daily instead of 4. Vitamin D and Calcium levels have been consistently excellent. Lastly, the price cannot be beaten if you buy these in bulk. Overall I'm very happy with all of Bio-Tech's dry vitamins (I take their A, E, and K, too) and I recommend them without reservation.

This D3 is very easy for me to digest and get into my system. Much better than the oil based D3 I've tried. However, this is the third time I've bought the "2 pack" but first time they shorted me one bottle. The Amazon sticker over the UPC label on the one 250 count bottle I did receive says "2 pack 500 count" too. So, someone made an error. A call to Amazon customer service got me a refund for their mistake.

This is the only OTC brand of vitamin D that has ever raised my levels to where they should be. I've encouraged many friends and family to switch to this brand.

I've taken these tiny pills for years and my doctor says keep taking them since my tests all look great...It is so very convenient to just click on Amazon, type in the name and click on order a bottle. It couldn't be any easier.
