An anti-oxidative, energy-boosting, and anti-aging nutraceutical composition containing fullerene substituted with functional groups, a medium chain triglyceride (preferably black seed oil), and the composition optionally includes one or more energy molecules not bound to the fullerene. Preferred functional groups and energy molecules include beta-hydroxybutyrate (more preferably D-beta-hydroxybutyrate) and carboxylic acids (e.g., caprylic acid and/or capric acid).
