Ingredients we group near Omega-3 fatty acids in our model - not interchangeable, but often read together.
- Alpha-lipoic acid (ALA)64/100Mixed evidence
Antioxidant used in research for diabetic neuropathy in some clinical contexts; OTC ‘metabolic optimizer’ claims are broader than proof.
- Curcumin66/100Mixed evidence
Bioactive curcuminoids have anti-inflammatory lab appeal; human absorption issues and mixed clinical outcomes limit certainty.
- Coenzyme Q10 (CoQ10)66/100Mixed evidence
Mitochondrial electron carrier; evidence clusters around statin-associated muscle symptoms contexts and some heart failure discussions - not a universal energy hack.
