Supplements

Mechanism

Dimethylated analog of resveratrol with 4x greater oral bioavailability. Activates SIRT1 and AMPK, reduces oxidative stress, and improves lipid profiles. Superior pharmacokinetics compared to resveratrol due to methyl groups protecting against glucuronidation.

Contraindications

  • Hormone-sensitive conditions (mild estrogenic activity)

Mechanism

Redox-active cofactor that supports mitochondrial dehydrogenase complexes, glutathione recycling, and glucose disposal.

Contraindications

  • Monitor in clients prone to hypoglycemia
