Potential effects on host defense The role of vitamin D in innate immunity is increasingly recognized. In conclusion the present study indicates that the neuropathy observed after taking a relatively high dose of vitamin B6 supplements is due to pyridoxine.

This means its possible for those who include animal-source based foods in their diet can still become vitamin B12 deficient if theyre eating foods that contain inactive B12 with active B12 sources 7. In nature β-carotene is a precursor inactive form to vitamin A via the action of beta-carotene 1515-monooxygenase. Vitamin B6 deficiency by forming an inactive derivative with pyridoxal phosphate.

Retinoids fat-soluble biologically active vitamin A found in animal foods Retinol. Nutt correctly states that cyanocobalamin releases a cyanide group for every molecule of B12 that is used. As you age your bodys ability to convert inactive B vitamins to their active usable form.
