NutraBio Acetyl L-Carnitine delivers 500mg per capsule, 1 gram per 2-capsule serving, in a clean vegetable capsule with no excipients, no fillers, no artificial colors, flavors, or sweeteners, and no preservatives. Acetyl L-Carnitine (ALCAR) is a stabilized, more absorbable form of L-Carnitine, and the key difference is that it crosses the blood-brain barrier far more readily. That is why it gets used for cognitive support rather than just fat metabolism. Its molecular structure resembles acetylcholine, so supplementing may support acetylcholine production alongside protein and membrane phospholipid synthesis. It also does the standard carnitine job of shuttling fatty acids into the mitochondria for energy. 90 veggie capsules, 45 servings.†

ALCAR vs. Standard L-Carnitine
Both support mitochondrial function, but Acetyl L-Carnitine is more easily absorbed and crosses the blood-brain barrier far more readily. That single difference is why ALCAR shows up in nootropic stacks while plain L-Carnitine stays in the fat-loss aisle. ALCAR also decreases lipid peroxidation and oxidized nucleotides, which standard L-Carnitine does not.†
The Acetylcholine Connection
Acetyl L-Carnitine's molecular structure resembles acetylcholine, the neurotransmitter central to memory, learning, and focus. Supplementing may support acetylcholine production along with protein and membrane phospholipid synthesis, which is the mechanism behind its use for cognition, visual memory, and attention.†
The Performance Side
ALCAR facilitates the metabolism of fatty acids for energy. Greater reliance on fat for fuel can spare muscle glycogen, which supports endurance and exercise performance and may contribute to reduced stored body fat. It has also been studied for reducing the respiratory exchange ratio and lactic acid accumulation during training.†
No Excipients, No Fillers
This is the NutraBio standard and it is worth noting. A lot of capsule products are padded with flow agents and binders that make manufacturing easier. NutraBio leaves them out, so what is in the capsule is the ingredient you paid for.†
Frequently Asked Questions
-
Should I take it on an empty stomach?
Yes, that is the label recommendation. Take 2 capsules 1 to 3 times daily, preferably on an empty stomach.† -
Is this better than regular L-Carnitine for fat loss?
Both support fatty acid transport. ALCAR's advantage is brain penetration, so choose it if you want the cognitive benefits alongside the metabolic ones.† -
Can I stack it with a stimulant fat burner?
Yes. ALCAR is stimulant-free and commonly stacked with thermogenics or taken before fasted cardio.† -
Is it appropriate for tested athletes?
Acetyl L-Carnitine is not prohibited by WADA or NCAA.†
