Analysis

This supplement provides 330 mcg of bioactive d-biotin, which is intended to support the enzymes that process sugar and fats. It is paired with alpha-lipoic acid in a sustained-release tablet to provide steady support throughout the day. It fits someone focusing on metabolic efficiency and cellular defense.

Because the biotin dose is much lower than in beauty supplements, it is not the best choice for hair or nail concerns. However, it is an excellent professional-grade option for those wanting to support their internal metabolic pathways. The sustained-release feature is a practical touch for consistency.

Pros

  • Sustained-release delivery
  • Uses bioactive d-biotin
  • Includes 300mg of alpha-lipoic acid
  • Supports metabolic enzymes

Cons

  • Biotin dose is too low for hair/nails
  • Contains more fillers for release
  • Focused only on metabolism

Warnings

  • Can lower blood sugar levels
  • Not for intensive beauty support
  • Consult if taking insulin
