Works Great! Pill Size Same As Davinci ADK!

My vitamin D is low. I love the combination of ADK Vitamin in one small capsule (A&K necessary for proper absorption of vitamin D). The small bottle and the small pill is a plus: it's easy to swallow, no after taste, and no upset stomach.

Excellent supplement

Very absorbable form of D3. My family has been using it for several years, never get sick. D3 blood levels have been shown to be one of the most important factors in whether an individual contracts viral infections, including the current covid sars virus. The darker the skin, the more D3 is required. Do the research and find out for yourself.
