D3-50 Cholecalciferol by Bio-Tech Pharmacal is a high-potency vitamin D3 supplement that may work to support general health in several ways. Notably‚ vitamin D may help maintain strong bones by promoting the absorption of calcium and phosphorous; at the same time‚ vitamin D might work to maintain steady serotonin production‚ which is important because serotonin is a neurotransmitter that’s involved in managing your mood as well as other bodily functions.

Every capsule of D3-50 Cholecalciferol provides 50‚000 IU (international units) of vitamin D3‚ which is the form of vitamin D that the human body naturally produces when your skin is exposed to natural sunlight.

Unlike other vitamin D supplements (which are fat-soluble)‚ D3-50 Cholecalciferol contains a dry‚ water-soluble preparation of vitamin D3. As a result‚ this formula may be easier to absorb.

Take one capsule per week unless otherwise recommended. At the standard dosage‚ each 100-capsule bottle of Bio-Tech Pharmacal’s D3-50 Cholecalciferol should last for about 14 months.

      I am 63 and have been taking one a week for probably 3 years. Four months ago I had blood work done. The physician asked me how I was keeping my Vitamin D so perfect. I showed her D3 50 Cholecalciferol by Bio-Tech Pharmacal and she told be to keep doing whatever I was doing. I have got a few friends and family taking it.

      Pros

      The results! Vitamin D is very important at my age and I have never eat right. Originally I got on it for muscle cramps. Will never stop taking it Also the cost. Bottle of 100 lasts almost 2 years taking it once a week.

      Cons

      Nothing

      D3 50 Cholecalciferol by Bio-Tech Pharmacal is a great product to take when getting sick to quickly boost D3 for immune support.

      Pros

      High D3 content in one pill. No need to take multiple pills for temporary D3 loading when sick.

      Cons

      Nothing

      I just started the D3 50 Cholecalciferol by Bio-Tech Pharmacal, and I only take it once a week, so I am not really aware of its effectiveness yet. But it is easy to take, and I am pleased that I found this recommended product at an economical price.

      Pros

      It is easy to take, and I am pleased that I found this recommended product at an economical price.

      Cons

      I have not found anything that I dislike about the product.

      I take D3 50 Cholecalciferol by Bio-Tech Pharmacal once a day because I have Hypoparathyroidism. It works great, my Vitamin D levels went from a 5 to an 8.5 in a short time. This is the only pure form I have found that doesn't have any bad additives. I was originally prescribed Calcitriol but because of the artificial coloring (I am allergic) I couldn't take it and I was sick on and off for a while until I found this at Nutrition Unlimited. I couldn't be happier, it's literally a life saver.

      Pros

      Pure, no bad additives, inexpensive, great quality.

      Cons

      None

      A year ago I was able to buy this product from a local pharmacy but they decided to go with a much higher retail price similar product. I got D3 50 Cholecalciferol by Bio Tech Pharmacal for my wife and I and over the past year it has helped our Vitamin D levels tremendously. I am just glad I could still get it at PureFormulas at a really great price. Thanks!

      Well I have only taken D3 Cholecalciferol by Bio Tech Pharmacal for a week. These are pills that my Doctor told me to get. I had mentioned to him that I was going to get my flu shot! Well folks I thought he was going to have a stroke. He said that the shots were full of Mercury! He recommend these pills and said if I thought I had the flu to take 3-5 of these a day for 3 - 10 days. These pills would take care of the flu. Then he said since I live in northern Michigan we have a lot of gray days durning the winter months. So I will let you know if they work.

      Pros

      Only have been taken them for about week!

      Cons

      See above.
