Doc Frank Mega D3 capsules are provided in sealed plastic containers, containing 30 capsules each. Each capsule provides 40,000 IU cholecalciferol in a highly-available formulation.

Many studies show that Vitamin D3 (cholecalcifero) is important in relieving depression, as well as fighting osteoporosis, diabetes, heart disease and cancer.  Most people nowadays do not get enough sun exposure to activate Vitamin D into Vitamin D3. 

It is becoming increasingly clear that the Recommended Daily Allowances for Vitamin D are inadequate for the daily demands of most people.


Contains Pure Vitamin D3 (Cholecalciferol) 40,000 IU (1,000 mcg) per capsule.

    Very Satisfied with this product. I like the idea of only taking it once a week and not feeling as if I am taking pills constantly

    I've been using Doc Frank's Mega D3 since September 2022. For the first time in years, my blood tests show a dramatically improved Vit D count. I feel amazing, and it has been the first winter season in more than 10 years that I didn't get horrible flu, bronchitis or pneumonia. Will never use another brand of Vit D3. Super product!!!

    I have been taking Mega D3 since joining the Fire course. I have made a lot of adjustments, so I cannot really comment on the D3 specifically. Easy to swallow and no side effects. I take it with a fatty meal.

    My follow up blood tests will reveal if my very low Vit D levels have improved.
