Product Information


ANDREW LESSMAN'S Vitamin D3 1000 contains 1,000 IU of Vitamin D3 in its most active and beneficial form – Cholecalciferol. Decades of overwhelming science has shown Vitamin D3 to be the single most important vitamin to supplement, since it is not readily available from even the healthiest diets. Vitamin D plays a multitude of vital roles in the body, including its essential role in all Calcium absorption, which makes Vitamin D as important as Calcium for bone and skeletal health. Vitamin D also possesses a long list of other benefits that have physicians and experts urgently recommending higher intakes. These other benefits include Vitamin D's essential role in supporting healthy immune system function, along with positive mood and brain function. Research has shown that we cannot rely on sun exposure to meet our Vitamin D requirements, and since there are also no abundant sources of Vitamin D in our diet, supplementation has become the only reliable source. Our extremely affordable Vitamin D3 1000 provides Vitamin D in its ideal form in an ultra-small, easy-to-swallow capsule. These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.

New formulation Very pleased to see the Calcium Citrate used in the newer formulation. Very pleased with this, as the kind of Calcium matters. Hope these can be on the TS in future, as this version far better than the original. The forms of Calcium and Magnesium do matter. Thank you.

A Light Bulb Went Off After experiencing a Sudden Death episode, I decided I needed to improve my health. On the advice of my neighbor, your best advocate, I started to watch and listen about your vitamins and supplements. When you discussed low Vit. D levels, A Light Bulb Went Off, and I decided to have my checked. Well, it was 10.5 very low. My doctor started me on 5,000 IU per day and I decided to take yours. Now, 2 years later, my level is 55.0. What a difference and I feel so much better, Most doctors do not discuss vitamins or supplements. We must educate ourselves. Please continue to educate and enlighten us because we hear you and it makes sense. They are the best and you get your moneys worth. Thanks again Judy K.

INCREDIBLE MIRACLE WORKER! During a visit with my doctor, it was discovered I was so vitamin d deficient I had none. (along with every other hormone / vitamins) My doctor prescribed 20,000 mg a day hoping this would help. Instead of using the prescription, I went to the website and ordered all of vitamins through ProCaps. Not only did it help, but the doctor wanted to know what I was using because he was so impressed with how my body reacted in such a short amount of time. I am now down to taking one capsules a week and still feel great, along with the levels being normal and stable. (I get my levels tested every three months) This product is amazing and for the price, a miracle worker. Who knew vitamin D plays such an important part to our overall health.

Great product but... I have taken your D for years now. I started out in single numbers.At my last Doctor yearly physical she did my D level count. My level was 100. She told me to stop them until our next visit. She told me my number was too high. For now, I stopped them, been three months now. When retests my level, I look forward to taking them again. I take your Calcium Magnesium too,so stopped both temporarily. It seems to work too good for my body. I am petite, thin, so I need to figure out my daily requirements. I know they certainly work, excellent product. Thank you for making them , and educating people at the same time.
