I appreciate that this is a proper formulation — not just one or two ingredients thrown together. The combination of plant extracts and B vitamins makes sense to me and I feel good taking it.

Why supporting your metabolism beats focusing on calories alone

Product option image

Your metabolism is the rate at which your body converts food and drink into energy. The higher your metabolic rate, the more efficiently your body processes the nutrients you consume — throughout the day, not just during exercise.

Metabolism Booster Extreme is designed for people who want to support this process from multiple angles. Rather than relying on a single ingredient, it combines plant extracts, zinc, and a full B-vitamin complex to contribute to fat metabolism2, normal energy-yielding metabolism (niacin), and the reduction of tiredness and fatigue (vitamin B6).

Instead of choosing between different supplements, this formula brings it all together in one daily capsule:

  • Green tea extract (Camellia sinensis)
  • Guarana extract
  • Panax ginseng extract
  • Ceylon cinnamon
  • Zinc
  • B-complex1 (B1, B2, B3, B5, B6, B7, B9, B12)

Give your body more — for a more complete approach to your goals.
