D3 Serum – natural vitamin D3 

A natural vitamin D3 that is derived from entirely natural sources and is suitable for vegetarians.

Product benefits 

  • Contains only live, natural sources of vitamin D3
  • Contains absolutely no synthetic vitamin D3
  • Just one drop is enough
  • Contains no excipients such as magnesium, corn, milk, soy, salt, sugar, wheat, yeast, artificial colours, flavours or preservatives 
  • Comes in a liquid form and is thus incredibly easy to take 

Suggested use 

Take one drop of vitamin D3 daily at mealtimes. Gently tilt the bottle and wait for a drop to drip from the bottle. Store in a cool, dry place.  


Vitamin D is found in very small quantities in certain types of food, in particular oily fish such as herring, mackerel, sardines and tuna. Vitamin D is also sometimes added to processed foods, including milk and fruit juices. We obtain most of our vitamin D through exposure to sunlight. 

Quantity and dosage 

Take 1 drop (0.022 ml) of vitamin D3 serum daily, which is equal to 1000 IU per serving (250% RDA). One bottle of PR Labs Vitamin D3 Serum contains 12,6 ml, so can last up to over 572 days, depending on your daily intake.  


  • Dr. Greg Plotnikoff, director of the American Penny George Institute for Health and Healing, Abbott Northwestern Hospital in Minneapolis and Dr. Soram Khalsa, an internist and director of the East-West Medical Research Institute have written much about vitamin D
  • Clinical laboratory specialist Dennis Mangan and vitamin D expert Dr. Cedric Garland have also written many articles about vitamin D
