Bio-Tech Pharmacal D3-5 (5000 IU), 250 Capsules – All-Natural Supplement – Supports Bone & Immune Health – No Dairy, Fish, Gluten, Peanut, Shellfish, & Soy – No Artificial Colors

Only D vitamin I’ll buy. Ive always been deficient but once I started taking these, my bloodwork comes back in the normal range. I’ve gotten lazy and stopped taking them and I notice a huge difference and then I get my bloodwork done and it shows I’m deficient. To bring me back up to the normal range, and in the winter months, I take three of these then back off to 2 in spring through fall. I’m now fairly consistent taking them daily.

Great vitamin D, I just had my labs done and my vitamin D levels were good! I was surprised because the pill is so small I thought I wasn’t getting enough vitamin D, I take two supplements of vitamin D daily.

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.

Great quality and value

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.

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!

This stuff saves me! My knees and joints cannot operate without Vitamin D. Our Dr. recommends this brand.
