VITAMIN B3
Vitamin B3, also known as niacin, is a water-soluble vitamin essential for various physiological processes. It plays a critical role in energy metabolism, DNA repair, and the synthesis of key molecules such as nicotinamide adenine dinucleotide (NAD) and its phosphate form (NADP). NAD and NADP are vital for cellular energy production and redox reactions.

Vitamin B3 is found in various foods, including animal products (e.g., meat, poultry, fish), plant-based sources (e.g., whole grains, nuts, seeds), and fortified foods (e.g., breakfast cereals).

VITAMINS B6 and B12
Vitamins B6 and B12 are also water-soluble vitamins and, like vitamin B3, are essential for various physiological processes. Specifically, vitamins B6 and B12 are involved in energy production, brain function, and DNA synthesis. They play particularly crucial roles in maintaining optimal health.

Rich food sources of vitamin B6 include poultry (e.g., chicken and turkey), fish (e.g., salmon and tuna), potatoes, bananas, and fortified cereals.

Rich food sources of vitamin B12 include meat (e.g., beef), dairy products (e.g., milk and cheese), and fortified plant-based foods (e.g., soy milk).

Vitamin B3 is a vital nutrient with diverse roles influencing human health, and, when used strategically, intelligently, and safely as a supplement, can offer potential powerful benefits influencing and impacting cardiovascular health, cancer prevention, and aging-related diseases.

Both Vitamin B6 and Vitamin B12 are fundamental for optimized human health, in particular, due to their roles in metabolism, neurological function, and disease prevention. While deficiencies can lead to serious health issues, such as anemia or cognitive decline, supplementation (under medical guidance) can very likely restore ideal levels effectively.
