Vitamin B3 Niacin


Use Life Extension Vitamin B3 Niacin because inadequate vitamin B levels impede food-to-energy conversion which is essential for bodily functions. Maintaining sufficient B vitamins is vital for overall performance, as energy fuels cellular processes throughout the body. Niacin is pivotal in metabolising glucose, fat, and alcohol into cellular energy and is important for overall health and energy metabolism.


Supplementing with niacin in your training program is beneficial when seeking improved endurance and cardiovascular health. Niacin aids in energy metabolism, which is vital during intense workouts. It can also help manage cholesterol levels, supporting heart health - a key consideration during rigorous training.


Life Extension Vitamin B3 Niacin is well suited to individuals pursuing intense training, especially those aiming to enhance cardiovascular fitness and endurance. It is particularly valuable for athletes and fitness enthusiasts seeking improved energy metabolism during workouts and better cholesterol management to support heart health.
