1. Bioavailability

This supplement provides the acetylated form of L-carnitine, which is better able to cross the blood–brain barrier than standard L-carnitine.

• Acetyl L-Carnitine (ALCAR) — more neurologically active than plain L-carnitine

• Supports energy metabolism, mitochondrial function, and brain health

• HPLC lab tested for potency and purity — ensures consistent quality

• Free of harmful impurities, reflecting NutraBio’s clean manufacturing standards

2. Dosage / Potency

It delivers a strong, research-aligned dose of ALCAR suitable for daily support.

• 1,000 mg per 2-capsule serving (500 mg per capsule) — common clinical range for cognitive and energy benefits

• Ideal for stacking with other mitochondrial or nootropic supplements

• Not a megadose — fits well as a maintenance or performance-support dose

• Flexible dosing — 500 mg single capsule or 1,000 mg two capsules
