Acetyl L-Carnitine Capsules give you acetyl L-carnitine on its own, the form of carnitine that crosses into the brain. Each capsule provides 550mg and you take two capsules once a day before eating, which is 1,100mg. One pot holds 60 capsules, which is a 30 day supply.
Carnitine carries fats into the mitochondria to be burned for energy. The body makes it from the amino acids lysine and methionine, with meat the main food source. The acetyl form carries an extra acetyl group and is the form that crosses into the brain, which is why people interested in brain and nerve support choose it over plain L-carnitine.
Acetyl L-Carnitine Capsules are most useful for:
For a sports training routine where carnitine tartrate is the usual form, Creatine Monohydrate Powder is the partner most people start with.
Each capsule provides 550mg of acetyl L-carnitine hydrochloride. There is nothing else in it apart from the vegetable capsule shell. ALCAR, ALC, acetylcarnitine and acetyl-L-carnitine hydrochloride are other names for it. There is no authorised health claim for carnitine, so Nutri Tailor describes it by what it contains.
Take two capsules once a day before eating. An empty stomach improves absorption, while the morning suits it because it supports alertness through the day. If you take it around training, take two capsules about an hour before the session.
The capsules are suitable for vegans and vegetarians. They are free from gluten, dairy and nuts. Anyone under 16 should not take them.
The capsules are made in the UK in a GMP certified cleanroom facility accredited to ISO 9001 and ISO 14001. Every batch is traceable from raw material to finished product. Like every supplement Nutri Tailor stocks, they are practitioner grade and guaranteed additive free.
Acetyl L-carnitine or L-carnitine tartrate?
Both supply carnitine, which carries fats into the mitochondria. L-carnitine tartrate is the form used in sports research and taken at gram amounts. Acetyl L-carnitine carries an acetyl group, crosses into the brain more readily and is the form used in research on memory, attention and nerves. Choose the tartrate for training and acetyl L-carnitine for brain and nerve support, or if you eat little meat and want the form that does both.
How much acetyl L-carnitine should I take a day?
Take two capsules a day, which gives you 1,100mg. A pot of 60 lasts 30 days.
When is the best time to take it?
In the morning before eating, or an hour before training. Taking it late in the day can keep some people alert when they want to wind down.
Can I take it with other supplements?
Yes. It works alongside Coenzyme Q10 Capsules and Acetyl CoA Support Formula Capsules, which support other stages of the same energy pathway. If you take a protein shake, take the capsules at a different time, because absorption is better away from protein.
Does acetyl L-carnitine have side effects?
It is well tolerated at these amounts. Some people notice a fishy body odour at high intakes, which two capsules a day is well below. If you take prescribed tablets, are pregnant or breastfeeding, speak to your GP or pharmacist first.
Why capsules rather than tablets?
A capsule is a cellulose shell around the powder, so it needs none of the binders or coating that hold a tablet together.

Acetyl L-Carnitine provides amino acids that serve as building blocks for proteins.
Often best on an empty stomach for optimal absorption.
Yes, though taking separately may improve absorption.
Amino acids build proteins, neurotransmitters, hormones, and enzymes. Each has specific functions beyond protein synthesis.
Generally yes for most people. Those with certain metabolic conditions should consult a practitioner.
Both supply carnitine, which carries fats into the mitochondria. L-carnitine tartrate is the form used in sports research for exercise and recovery and is taken at gram doses. Acetyl L-carnitine carries an acetyl group, crosses into the brain more readily, and is the form used in research on memory, attention and nerve health. Choose the tartrate if the aim is training; choose acetyl L-carnitine if the aim is brain and nerve support or you eat little meat and want the form that does both.
Tablets need binders, fillers and a coating to hold their shape. A capsule is a cellulose shell around the powder, so it carries no binders and breaks down quickly once swallowed.
