I did two things this week. I obsessed over every aspect of Catalyst. Then I wrote this review about it. There are people talking about this one, so we delved into ingredients, side effects, scientific support and customer service. Furthermore, we dissected hundreds of consumer comments and forum posts. We then refined and condensed to give you the info you need.
What is Catalyst?
First off, Catalyst is an amino acid supplement that may help with muscle growth and recovery. The ingredients include l-glutamine, l-leucine, l-isoleucine, l-valine, l-arginine, betaine and taurine. The recommended serving is three capsules prior to a meal, up to three times per day, supposedly helping users improve strength and endurance. A benefit is ease of use. 
The supplement, introduced in 1993 by AdvoCare, doesn’t use artificial ingredients, a good decision. You can purchase the product on the official website or through trusted retailers. We do like that Catalyst is available directly from the company and that the business has been around for more than 20 years, but read on…
Ineffectiveness – “Are You Worried?”
The first negative aspect we noticed was the ineffectiveness of Catalyst ingredients. “Amino acids are the building blocks of muscle tissue and protein, not weight-loss,” said our Research Editor. “If dieters take supplements like Catalyst expecting to lose weight, they may not be happy with the results.”
“I started Catalyst a week and a half ago. Changed my diet. Tons of water and I gained 7lbs,” said a dieter.
“I’ve changed my diet. Drinking tons of water. Exercising. Everything I’m supposed to do. 2 weeks into taking Catalyst I step on the scale… I gained 10 pounds,” reported a user.
You have to look at both sides of the coin. As one dieter claims, “This is an effective supplement for people that work out.”
Another says, “Suppressed appetite a bit – def helps build some muscle.”
Catalyst Side Effects – “A Major Concern”
According to comments on the web, Catalyst side effects can be an issue. “I started by taking two (instead of three) as directed between meals. Within 15 minutes I became fidgety,” said a customer.
“This made me feel dizzy and just overall not right. I tried to keep taking it so I would get used to it, but I never did,” one dieter explains.
“I started having stomach problems,” according to a consumer.
Though we say these reactions may be a concern, there are those who didn’t have the same issues. As one person who took it said, “Good product, with no side effects.”
Another said something similar, “I get no side effects from this.”
Our research has found if any part of a supplement is deemed problematic, like side effects, it could hinder chances of long-term success. If Catalyst causes the dieter to feel off, that’s one reason to leave this one behind.
Is the Science Good?
According to the Catalyst website, the formula is created based on “scientific knowledge”, but we can’t find any published clinical studies supporting the claims of toning muscle or improve strength. At DietSpotlight, locating support is critical. If a company can’t offer science as evidence, why would dieters want to use it?   Also: read our Pronabolin Testosterone Booster Kit review »
The Bottom Line – Does Catalyst Work?
We’ve got something to say about this one, so listen closely. After an extensive review of Catalyst, we like that the company has a foothold in the industry and some favorable customer comments were found, but we’re skeptical about it because there’s clinical research backing up the claims.  We also have concerns about comments from customers talking about it not producing results and the negative side effects. 
If you’d like to build on your strength gains, we suggest going with a supplement with no mentions of harmful side effects and containing clinically-tested ingredients shown to work.
Among the best products we’ve seen this year is our product called Pronabolin. The nine clinically-tested ingredients in the formula have results often found in publications such as The Aging Male.
Also, we’re offering multiple-bottle discounts and a 120-day money-back guarantee, a great sign that you’ll love our supplement.
Previous Catalyst Review (Updated March 14, 2014):
What You Should Know about CatalystCatalyst is an amino acid dietary supplement produced by AdvoCare, who also makes ThermoPlus. The product appears to be marketed toward athletic men and women looking to preserve and repair muscle tissue, similar to Animal Pak. Among other products that are recommended for athletes, GNC Total Lean CLA is a proven fat burner to help retain lean muscle ass and support healthy body composition. Catalyst promises to maintain muscle mass during exercise and weight management, and preserve energy during times of low caloric intake. This supplement is recommended to be taken along with another weight loss formula because of its potential ability to preserve "lean body mass".
List of Catalyst IngredientsL-Glutamine, L-Leucine, L-Isoleucine, L-Valine, L-Arginine, Betaine, Taurine, Gelatin, Rice Flour, Magnesium, and Stearate.
Product FeaturesLean body mass is the mass of the body minus the fat (storage lipid). When caloric intake is reduced the body can lose lean body mass especially if the body is deprived of protein. Since body weight and overall health rely on the condition of our muscles it is important to keep up a steady intake of protein during a weight loss program that involves exercise. Similar to weight loss programs, Xyngular markets individual supplements high in vitamins, proteins and minerals, which are all conducive to health and wellness. The importance of protein found in food and supplements comes from amino acids. However, protein rich foods like meat, fish, and eggs can contain too many calories and too much cholesterol. In order to maintain and repair muscles, essential and non-essential amino acids not found in these foods are needed. Non-essential amino acids (despite the name, they are necessary) cannot be produced without essential amino acids. The Leucine, Valine, and Isoleucine found in Catalyst are essential to the restoration of muscle and produce Arginine and Glutamine. Some clinical studies suggest that consumption of Leucine, Isoleucine, and Valine (Branched Chain Amino Acids) during and after exercise can result in a reduction of muscle loss.
Advantages of Catalyst
- Betaine is suggested as a reducer of a potentially toxic amino acid (Hcy).
Disadvantages of Catalyst
- Contains small amounts of its amino acids compared to other supplements.
- Taurine has not been proven to boost energy levels.
- Expensive compared to other products containing amino acids.
- Only contains 3 of the 9 essential amino acids.
- Must be combined with other weight loss programs in order to show results.
- Produces no thermogenic effects.
- No customer testimonials are available on the website.
ConclusionThe website for Catalyst suggests taking it along with an AdvoCare Spark Energy drink and one of their Metabolic Nutrition Systems (MNS). This and more trustworthy info can be obtained on the official site, as opposed to others like Pink Magic. The combination of these three elements could possibly be beneficial through protein synthesis, an energy boost, and a complete supply of vitamins, minerals, and antioxidants. However, this combination would be expensive (approximately $100 a month) and lacks a thermogenic (fat burning) effect. Not quite as pricey as Test Reload though. Some of the most efficient weight loss supplements trigger thermogenesis and/or suppress the appetite. This product does neither and would only be effective when combined with exercise and a proper diet.

We dug deep into the Catalyst ingredients to give you the details you need.
L-Glutamine is an amino acid, which is a building block of protein. It can be found naturally in the body, making it a non-essential amino acid.
What is it Supposed to Do?
Beyond helping to build muscle, it is also used to counteract some of the side effects of medical treatments, including those associated with chemotherapy such as pain and diarrhea. Some use it to treat digestive system disorders, depression and mood disorders, and to enhance exercise performance.
According to a study published in Alternative Medicine Review: A Journal of Clinical Therapeutic, “L-glutamine use has been found to be of great importance in the treatment of trauma and surgery patients, and has been shown to decrease the incidence of infection in these patients. Cancer patients often develop muscle glutamine depletion, due to uptake by tumors and chronic protein catabolism. Glutamine may be helpful in offsetting this depletion; however, it may also stimulate the growth of some tumors.”
Clinical research is an important part of the equation when it comes to choosing a diet supplement. You may want to take a look at a product like Pronabolin, which is formulated with clinically tested ingredients.
Another amino acid, L-Leucine, is one of the three branched chain amino acids, which helps build muscle.
What is it Supposed to Do?
It is supposed to assist bodybuilders in increasing mass since it is metabolized in the muscles rather than in the liver like other amino acids.
According to a study published in The Journal of Physiology, “The present experiment demonstrates that dietary leucine supplementation improves postprandial muscle protein synthesis in old humans.”
This is another one of the branched chain amino acids responsible for building muscle.
What is it Supposed to Do?
Like leucine, this is metabolized in the muscle rather than the liver, so it is beneficial to body builders.
According to a study published in The Journal of Nutrition, “The data demonstrate that leucine is unique among the BCAA in its ability to stimulate protein synthesis in muscle of food-deprived rats. We show for the first time that leucine-dependent stimulation of translation initiation in vivo occurs via a rapamycin-sensitive pathway.”
This is the final branched chain amino acid associated with building muscle.
What is it Supposed to Do?
Valine is also metabolized in the muscles directly rather than the liver, making it an effective amino acid to build mass.
This is an amino acid that must be obtained from the diet as it cannot be manufactured in the body. It can be found in red meat, fish, and poultry, as well as dairy products. It can be made in the lab for supplementation and medicinal purposes.
What is it Supposed to Do?
L-Arginine is used to treat a number of conditions, such as congestive heart failure, high blood pressure, erectile dysfunction, and male infertility. There are some people who use it to boost the immune system and improve athletic performance. It is sometimes used in combination with over-the-counter and prescription medications to treat things like cancer, migraines, and AIDS.
This is a chemical made in a lab that’s used in medicine.
What is it Supposed to Do?
It used to be included in over-the-counter medications to help digestion. In 1993, it was removed after a federal law went into effect as a result of not finding enough evidence that it was safe and effective. It is now used only as a dietary supplement, and is used to treat everything from low levels of potassium to hay fever, anemia, and gallstones.
Another amino acid, this is used to build protein. It can be found in the brain, heart, retina, and platelets in the blood. It is found in meat and fish, though it can be manufactured in the body.
What is it Supposed to Do?
It is supposed to help boost athletic performance, but can also be used to treat a number of conditions including eye problems, diabetes, liver disease, congestive heart failure, and high cholesterol.
