Acetyl L-Carnitine (ALCAR) is an acetylated form of L-Carnitine which is similar to typical L-Carnitine but is able to cross the blood-brain barrier. L-Carnitine is a compound naturally produced by the body which plays a key role in the mitochondrial oxidation of long-chain fatty acids.

When taken as a supplement, ALCAR supports exercise endurance and stamina, particularly for resistance training. Since ALCAR can cross the blood brain barrier, unlike the non-acetylated L-Carnitine it supports cognitive function and attention.

Recommended Dosage

As a supplement for exercise endurance or cognitive support, take 2-4 capsules (1000 mg – 2000 mg) per day on an empty stomach. It’s not recommended to take over 6 capsules (3000 mg) per day due to increased risk of side effects.

Acetyl L-Carnitine Side Effects

ALCAR is safe and well tolerated at typical doses, and while side effects are rare reported side effects include upset stomach, nausea, dry mouth, headaches, and restlessness.

There is some evidence that ALCAR may worsen symptoms in people suffering from bipolar disorder so people with this condition should avoid ALCAR. There has also been some concern that ALCAR may interfere with the thyroid hormone at high doses so people with under-active thyroids may want to avoid ALCAR.

No issues so far.
Taking Acetyl L Carnitine hoping it will slow the rate of Alzheimer disease progression, improve memory, and improve some measures of mental function and behavior. Also for heart health
Acetyl L-Carnitine is very good for health and well being.
I have not been taking this long enough to rate it yet. I gave it five stars because you can't submit without doing so. I don't question the quality at all; I already know Double Wood has integrity and products that work.
Great Products. I take them every day. Great for you Mind.
I've used the product for several years and I use the Double Wood brand because it's Made in USA, non-GMO & purity tested. I think it helps reduce my brain fog and increase my attention span
