This creatine and acetyl-L-carnitine powder delivers a full 5g of **Creatine Monohydrate** alongside 2,000mg of **Acetyl-L-Carnitine** per scoop, with both actives sitting at the top of their clinically studied ranges, so you're getting effective doses of each rather than a token amount. The 5g of creatine lands right at the gold-standard maintenance dose backed by hundreds of trials for strength, power, and high-intensity output.

Acetyl-L-carnitine is the form of carnitine that crosses into the brain, which is why this leans toward mental energy and focus as much as physical performance. At 2,000mg you're at the upper end of the range used in cognitive and exercise studies, supporting daytime alertness while helping move fatty acids into your cells for energy. Between the two, you're covered for both the muscle and everyday-energy goals this is built around.

One nuance worth knowing: creatine's emerging cognitive research typically uses higher doses, around 10g a day, so the 5g here is dialed in for training benefit more than brain-specific goals. The powder mixes into any drink, making it an easy single-scoop way to hit clinical doses of both actives at once.
