Vitamin B3 (Niacin)
Health Benefits of Vitamin B3
- Energy Production: Essential for converting food into energy by aiding in the function of coenzymes NAD and NADP, which are crucial in cellular metabolism.
- Supports Heart Health: Helps improve cholesterol levels by raising HDL (good cholesterol) and lowering LDL (bad cholesterol) and triglycerides.
- Maintains Skin Health: Promotes healthy skin and helps in preventing skin conditions such as dermatitis.
- Brain Function: Supports cognitive function and may help reduce the risk of neurodegenerative disorders.
Interaction with Other Vitamins and Minerals
Key Interactions
- Other B Vitamins: Works synergistically with B1 (Thiamine) and B2 (Riboflavin) to enhance energy production and maintain overall health.
- Vitamin B6 (Pyridoxine): Supports the conversion of niacin from tryptophan, an amino acid, thereby boosting niacin levels in the body.
- Magnesium: Essential for the proper functioning of enzymes that require niacin in metabolic pathways.
- Zinc: Contributes to the enzymatic activity involving niacin for DNA repair and metabolic processes.
Potential Effects of Imbalances
- Deficiency Issues: Can lead to pellagra, characterized by dermatitis, diarrhea, dementia, and, if untreated, can be fatal.
- Excess Intake: High doses of niacin can lead to side effects such as flushing, liver damage, and gastrointestinal discomfort.
