All about fruitarianism with a long-term fruitarian, Lena

Based on available biochemical, clinical and epidemiological studies, the current US recommended daily allowance (RDA) for ascorbic acid ranges between 75 - 120 mg per dayto achieve cellular saturation and optimum risk reduction of heart diseases, stroke and cancer in healthy adults

  • Males - 90 mg a day,
  • Females - 75 mg a day,
  • Smokers - +35 mg a day (35 mg/day more)

Fresh fruits, vegetables and also synthetic tablets supplement the ascorbic acid requirement of the body. However, stress, smoking, infections and burns deplete the ascorbic acid reserves in the body and demands higher doses of ascorbic acid supplementation.

Ascorbic acid and its derivatives are widely used as preservatives in food industry.

Vitamin B3 Niacin

Vitamin B3, Niacin, nicotinic acid, helps to convert food into energy and is essential for healthy skin, blood cells, brain, and nervous system. It is one of 8 B vitamins. It is water-soluble, which means it is not stored in the body. It has 2 other forms, niacinamide (nicotinamide) and inositol hexanicotinate, which have different effects. 

Niacin occurs naturally in food and can also be made by your body from the amino acid tryptophan, with the help of B6

It is rare for anyone in the developed world to have a Vitamin B3 deficiency; alcoholism is the main cause of it in the US.
