Acetyl L-Carnitine (ALCAR) is a highly bioavailable form of L-Carnitine that supports both physical energy and cognitive function. Unlike standard L-Carnitine, the acetyl group allows it to cross the blood brain barrier, making it effective for brain health as well as cellular energy production.

ALCAR works by transporting fatty acids into the mitochondria, where they are burned as fuel. This process is central to how your cells produce energy, particularly in the brain and muscles where mitochondria are most concentrated. It also assists with the conversion of choline into acetylcholine, a neurotransmitter involved in memory, learning and muscle coordination.

Each capsule provides 550mg of Acetyl L-Carnitine HCl in a clean formulation with no fillers or binders. The body's natural production of carnitine declines with age, and vegetarians and vegans tend to have lower levels as carnitine is found primarily in meat and eggs.

ALCAR is commonly recommended for people experiencing mental fatigue, brain fog, low physical energy, or those looking to support cognitive function as they age. It is also used by athletes to support fat metabolism during exercise.

Take 2 capsules once per day before eating.

Taking ALCAR on an empty stomach improves absorption. For energy and cognitive support, morning dosing works best as it supports alertness and focus throughout the day.

If you are using ALCAR to support exercise performance, take 2 capsules approximately 1 hour before training. This allows time for the fatty acid transport mechanism to become active before your workout begins.
