Built for energy, blood flow, and training output, this blend delivers 1,400mg of carnitine per serving across three forms — squarely inside the 1–3g range clinical trials use. The piece that sets it apart is **GlycoCarn**, a glycine-bound propionyl-L-carnitine studied for raising nitric oxide and blood flow, the angle that can translate to a better pump and more power during hard training.

Alongside it sits 800mg of brain-penetrating **acetyl-L-carnitine**, the one carnitine form that actually crosses into the brain — where the strongest research points to cognitive support in older adults and age-related mental decline. A third arginate-bound form adds 300mg of that same acetyl backbone, bringing your total acetyl-L-carnitine to 1,100mg per serving, a genuine dose for the energy-metabolism and mental-clarity side of carnitine.

Here's the honest fit note: your body makes its own carnitine, and meat-eaters top up more from food, so a young, healthy, well-fed person may feel little. The clearest payoff goes to older adults, hard-training athletes, vegetarians, and anyone running low. The label lets you take up to two servings daily, which pushes you toward the upper end of the studied range if you're specifically chasing the blood-flow and exercise effects GlycoCarn is built around.
