This blend stacks three forms of carnitine to a combined 1,400mg per two-capsule serving, putting your daily intake at 1,400 to 2,800mg depending on whether you take it once or twice a day — right inside the 1–3g range used in research on energy, fatigue, and exercise recovery. Carnitine's job is to shuttle fatty acids into your cells' mitochondria so they can be burned for fuel, and the bulk here, 800mg, is **Acetyl L-Carnitine**, the form that crosses into the brain and carries the strongest evidence for mental sharpness and age-related cognitive support.

The remaining 600mg splits between two specialized forms. **Glycine Propionyl L-Carnitine** has been studied for blood flow and exercise output, and the arginate form pairs carnitine with arginine. Both absorb well, so the full dose counts toward your daily total.

The honest caveat: your body makes its own carnitine from amino acids, so if you're young, healthy, and eat meat regularly, the noticeable lift may be modest. The clearest benefits, less fatigue and better recovery, show up in older adults, in people who run genuinely low, and during hard training. If that's you, this reaches a clinically meaningful dose.
