Acetyl L-Carn X500 comes in jars of 100 capsules that each contains 500mg of pure Acetyl L-Carnitine (ALCAR). This is an amino acid naturally produced in small amounts inside your body. X500 is sold by VitaXtrong, a company based out of Los Angeles, California.

The founders claim to be bodybuilding enthusiasts searching for the best and highest-quality ingredients to make supplements that work. VitaXtrong is well-regarded and active people often purchase their products.

On their website, the company says, “offer full label transparency, so you always know how much of each ingredient you’re getting. The quality of our ingredients is nothing less than pure, pharmaceutical-grade.

Each formula is built with ingredients clinically proven to work in real athletes.” So far, we haven’t seen anything that would contradict this statement. VitaXtrong does seem to have high standards and quality products made from good sources.


1) What is Acetyl L-Carn X500?

Each capsule of X500 contains nothing but 500mg of natural Acetyl L-Carnitine. No chance of contaminants or byproducts. VitaXtrong promises that these will help you burn unwanted fat and convert it to energy, improving your workouts while supporting cognitive functions.

ALCAR is not used for fat-burning. However, it gives you additional energy when active, keeping you alert and staving off fatigue. It’s also possibly useful for improving memory, reducing pain, and increasing sperm count in men.

Both women and men use Acetyl L-Carnitine, although men may see more benefits overall.

Pregnant or nursing women shouldn’t use this supplement due to insufficient research on children’s potential impact. It’s likely safe, but it’s always best to stay on the safer side.


2) Details on Acetyl L-Carn X500 Ingredients and Uses

Acetyl L-Carn X500 contains the following ingredients: Acetyl-L-Carnitine

3) Is Acetyl L-Carn X500 Right for You?

Each bottle contains 100 pills. It’s nothing but 500mg of Acetyl L-Carnitine, and the capsule itself is made of cellulose. VitaXtrong promises that these will help you burn unwanted fat and convert it to energy, improving your workouts while supporting cognitive functions.

One of the most significant benefits of X500 is that it’s a pure product. You won’t find any filler or ingredients that might interfere with each other.

By itself, ALCAR is proven to work and have positive results. It has various uses, both physical and mental, and is known to help with your energy levels.

As is typical with supplements, pregnant or nursing women should not take ALCAR, as interaction needs more study. Rare side effects include an upset stomach. You also shouldn’t use this if you have an under-active thyroid.

Taking X500 daily while going about your usual diet and exercise routine has noticeable improvements. You won’t lose as much energy, and you’re likely to burn unhealthy fat. It’s considered safe to use with most other supplements, and many supplements include ALCAR for its benefits.

X500 could be viewed as a replacement for caffeine in the diet of workout enthusiasts due to its physical energy and mental clarity effects.
