That Core Ingredient Is: Vitamin B3 (Niacin)

Vitamin B3, called niacin, is a water-soluble vitamin linked to energy metabolism and nervous system function.

This form is a pure niacin supplement delivered in capsule form to support normal physiological roles and without any dosage instructions.

What Does Vitamin B3 Do?

Vitamin B3 helps support energy metabolism and plays a role in maintaining normal cholesterol balance, in line with EFSA and NHS guidance.

Dr. Carlson of Mayo Clinic Proceedings found that niacin can influence lipid profiles, contributing to HDL, LDL, and triglyceride balance in some populations. Niacin also acts as a precursor to NAD and NADP, which are involved in energy production and cellular processes.
