Reviews
Acetyl-L-carnitine (ALCAR), the short-chain ester of Carnitine, is a common dietary supplement readily available in health food stores, claimed to improve energy levels and muscle strength. ALCAR has numerous effects on brain and muscle metabolism, protects against neurotoxic insults and may be an effective treatment for certain forms of depression. Boosts brain power: ALCAR is an anti-ageing nootropic or smart drug that helps your brain perform better. Burns fat and builds muscle: ALCAR can also give you an edge in the gym. It shuttles fuel (in the form of fatty acids) to your mitochondria, where it’s burned for energy.
L-carnitine is not only good for weight loss & fitness, but it is also beneficial for heart health. With this product I didn't notice any smell or taste at all, and it didn't upset my stomach - even when taken on an empty stomach. They are very easy to swallow. I am very happy with this supplement. It is high quality, and it does seem to help. I can tell the difference when I take this; my energy level seems to be more stable.
I've been taking L-Carnitine off and on for a few years, often together with Alpha Lipoic Acid. Acetyl-L-Carnitine is also good for helping my energy.
Bought this many times, it actually works and seems to burn away fat and makes you hungry earlier.
Great only one per day needed. Don’t know if they work yet as not been taking long enough
