One of the most impressive buffers against your muscles calling it quits is carnosine, a dipeptide that helps to reduce fatiguing acid build up when strength training. And carnosine is composed, in part, by beta-alanine, so the greater the pool of this amino acid, the better your body’s ability to fight muscle fatigue.

In a 2010 study in Nutrients1 researchers found taking beta-alanine multiple times throughout a day elevated muscle carnosine levels by as much as 66 percent. Beta-Alanine helps reduce muscle fatigue so you can work out harder and longer.

Laboratory of Applied Nutrition2 found that taking beta-alanine supplements can help your muscles endurance, specifically performance during high intensity anaerobic exercises like sprinting, jumping, and weightlifting.

When researchers from The University of Oklahoma3 combined beta-alanine supplementation with high-intensity interval training, they found that athletes were able to train at 90 to 110 percent of their VO2 max—the maximum volume of oxygen your body can use—for the first three weeks, and then at 115 percent of their VO2 max for another three weeks. Not only did their threshold increase, but they also reached their peak oxygen consumption faster after the first three weeks.

STRONG Performance Fuel contains 1600mg of Beta-Alanine, the precise amount your body can absorb at one time, any more and you’ll simply pee it out. However, taken 1-3 times a day and you’ll be stocked up, ready to slay dragons and crush muscle fatigue.

BCAAs  – Leucine, Valine and Isoleucine

BCAAs enhance strength, endurance and decrease fatigue. This is because the body burns BCAAs as energy to replenish ATP (Adenosine Tri-Phosphate) levels. This is the prime energy molecule in the human body. They also delay fatigue by inhibiting tryptophan receptors in the brain. They preserve the integrity of muscle fibres that decreases muscle soreness and can allow you to train more frequently1

Additionally, BCAAs reduce muscle catabolism (degradation) by protecting lean muscle tissue2 and increase the formation of new mitochondria and thus reduce age related muscle loss3. The body metabolises BCAAs predominantly in the muscles, this is why they are so important in the energy supply of muscle tissue.

Leucine plays a vital role in the generation and preservation of muscle tissue by supporting protein synthesis in the muscle and liver, as it blocks the breakdown of muscle tissue. It regulates the energy supply of the body and plays a part in the synthesis of glucose.

Valine is important in the biosynthesis of protein and the proper conversion of food into energy and plays an important role in building physical strength and muscle.

STRONG Performance Fuel contains the most effective ratio of 2:1:1 of leucine to valine and isoleucine, to enhance muscle protein synthesis. This results in greater muscle hypertrophy and maintenance of lean muscle during non-training periods. This happens especially when consumed with amino acids beta-alanine and glutamine.

A naturally occurring amino acid, is one of the main catalysts for building protein and essential for athletic performance and building lean muscle.

During strenuous physical activity, glutamine levels drop; by supplementing glutamine you can maintain adequate levels. It can take up to five days to get back to baseline level, so it is important to consistently get enough L-Glutamine when engaging in strenuous physical activity. It also helps keep muscles hydrated and helps shorten your recovery process post-training.

L-Glutamine also helps your body recover from wounds and illness. Studies have found that taking L-glutamine can help boost the immune system while reducing the probability of infection and L-Glutamine has been shown to have a positive effect on repairing the intestines of people suffering from leaky gut syndrome as it helps to repair tissue and reduce inflammation.

Note: Always see a physician before taking any supplement. L-Glutamine should not be taken by people suffering from Reyes syndrome, who have liver disease, and/or kidney disease.


Glycine has been found to help inhibit the deterioration of valuable protein tissue that forms muscle and boosts muscle recovery. Known also as an anti-aging amino acid because of how it helps maintain lean muscle mass into old age, stimulates the secretion of human growth hormone, prevents loss of cartilage in joints, and even improves daytime energy, physical performance and mental capabilities.

Glycine is used during the biosynthesis of creatine, which provides muscles with a direct source of fuel to repair damage and grow back stronger. It also helps provide cells with energy thanks to its role in the conversion of nutrients from your diet, helping feed hungry muscle tissues and boosting endurance, strength and performance. It also has benefits when it comes to hormone production and regulation, helping the body naturally synthesize steroid hormones that regulate the ratio of fat to muscle and control energy expenditure.

Glycine is beneficial for supporting cognitive performance and the central nervous system because it helps regulate the metabolic synthesis of certain nutrients that the brain and nerves use for energy. It helps regulate nerve impulses throughout the body by balancing electrolyte levels, such as calcium, chloride and potassium.

Glycine also has implications for helping improve sleep, mental performance, bodily sensations, moods, memory and behaviors. Glycine works with other amino acids, including taurine and gamma-amino butyric acid as an inhibitory neurotransmitter.

Due to its roles in the central nervous system and the digestive system, glycine can help boost energy levels, balance blood sugar and prevent fatigue. It helps directly bring nutrients to cells and tissue for energy at all times of the day.


Taurine helps muscles work harder, longer and safer. Taurine increases muscle contractility resulting in more powerful workouts. Taurine also helps to remove lactic acid build-up which means you can train for longer. It helps fight against oxidative stress due to its cellular protective properties, protecting muscles from damage and delaying onset muscle soreness.


Creatine is a substance that exists naturally in the body, helping to fuel our muscles, particularly during heavy lifts and high intensity work. One of the most well researched supplements, it has been shown to have serious benefits for both power and strength outputs.

One recent review published in the journal Molecular and Cellular Biochemistry looked at over 500 creatine studies to find that even short-term supplementation resulted in strength gains of up to 15 percent, and improved single effort sprint performance by around five percent.

Nearly all of the studies that demonstrate creatine’s effectiveness use creatine monohydrate.  This particular type of creatine has been used for decades and is considered in many circles the “original and the best,” and is by far the most well-researched.

Of particular importance for women seeking to lean out are the gains in lean mass seen in athletes with creatine use. Over 4-12 week training cycles, subjects have been shown to gain twice the amount of lean mass compared to those receiving a placebo. These findings have been consistently reported in studies performed by the International Society of Sports Nutrition.

Creatine is responsible for increasing metabolic activity in the body which boosts the energy supply to chemical processes. Increased metabolism helps in using the extra fat in the body and protects the breakdown of muscle. Women usually lose weight slowly so creatine can help increase metabolism which may lead to faster weight loss and increasing lean muscle.
