How it works, simply
It interacts with cardiolipin, a lipid in the inner membrane of mitochondria, the cell's energy-producing structures.
What the evidence tells us
FDA accelerated approval is indication-specific and based on a surrogate endpoint. Confirmatory evidence is required to verify clinical benefit.
Forzinity has a narrow accelerated US approval for Barth syndrome in patients weighing at least 30 kg. This does not validate general anti-aging or recovery claims.
Approved use: United States: Forzinity to improve muscle strength in adults and children with Barth syndrome weighing at least 30 kg, under accelerated approval. Other mitochondrial research and RUO SS-31 vials do not inherit this approval.
