Mypre Ingredients & Nutrition Profile

Below we provide a breakdown of the active ingredients used in the Mypre workout formula. With our in-depth analysis, find out why these ingredients are included and how they work to boost your performance in the gym.

Mypre label

Thiamin: 165 mcg – Known as thiamin, or vitamin B1, this first ingredient is one of eight B-complex vitamins. Thiamin’s primary role is to convert carbohydrates into glucose (energy) for the body to use. Further, thiamin metabolizes proteins and fats and plays a role in muscle contraction. Sometimes referred to as an ‘anti-stress’ vitamin, vitamin B1 may play a role in strengthening the immune system and helping the body function under stress.

Riboflavin: 210 mcg – Riboflavin, or vitamin B2 is another b-complex vitamin that works to convert food into energy and fuel for the body. Riboflavin is critical for athletes as it assists in fat and protein metabolism. Riboflavin is an important nutrient for body growth, development and production of red blood cells. In addition to supplying the body with energy, riboflavin has also been identified as an antioxidant which helps fight potentially harmful particles, known as free radicals.2,3

Niacin: 2.4 mg – Commonly known as vitamin B3, niacin is a water-soluble B vitamin not stored in the body, making it essential to obtain through diet and supplementation. In the body, niacin helps the digestive system and central nervous system function. Proper nerve function is critical for muscle contraction and building muscle strength. Along with other B-complex vitamins, niacin also assists in converting glucose into energy.4

Vitamin B6: 210 mcg – Required for more than 100 enzyme reactions, vitamin B6 is important for the breakdown of proteins, making antibodies and maintaining nerve function. Vitamin B6 also contributes to hemoglobin production and helps regulate blood sugar levels. In the body, hemoglobin is responsible transporting oxygen from red blood cells to the tissues.5,6

It’s suggested that as you consume more protein, you should increase levels of vitamin B6 to ensure proper protein breakdown.6

Folic Acid: 40 mcg – A type of B vitamin, folic acid or folate, plays an important role in the production of new cells. Experts think that folic acid may also be beneficial for maintaining a healthy heart and preventing cell change or damage that can lead to cancer development. A deficiency in folic acid has been linked to muscle weakness, weight loss, anemia and depression.7,8

Vitamin B12: 0.6 mcg – As an essential, water-soluble vitamin, Vitamin B12 maintains nerve and blood cells and helps DNA synthesis occur within the cell. A deficiency in vitamin B12 may lead to anemia and make individuals feel tired, weak and affect sports performance.9

Biotin: 30 mcg – Important for the formation of glucose and fatty acids, biotin helps produce fuel for the body. Biotin also helps metabolize amino acids and carbohydrates. For adolescents and adults, 30-100 mcg is recommended as the normal daily nutrient intake.10

Pantothenic Acid: 1 mcg – Pantothenic acid, or vitamin B5 is another B vitamin important for producing energy within the body. B vitamins help metabolize fats and protein in the body and maintain the nervous system.

In addition to manufacturing red blood cells, vitamin B5 is essential to producing stress-related and sex hormones, like testosterone.11

Calcium: 10 mg – As the most abundant mineral in the human body, calcium is important for development of strong bones, but also maintains proper function in the heart, nerves, muscles and other body systems.12

In the body, calcium helps muscles contract and assist nerves with delivering messages between the brain and different body parts. Calcium is used to release hormones and enzyme reactions that affect almost every part of the body.12

Magnesium: 4 mg – A cofactor in more than 300 enzyme reactions, magnesium has a variety of benefits including regulating blood pressure; assisting in tissue repair; protein synthesis; maintaining muscle and nerve function; and metabolizing protein, fats and carbohydrates.13

Magnesium is also important for the transportation of other nutrients such as calcium and potassium throughout cell membranes, a function critical to athletes as it facilitates muscle contraction, impulse conduction and maintaining a normal heart rhythm.13

Did you Know: Estimated sales of chromium supplements reached $85 million in 2002, 5.6% of the total mineral supplement market.14

Chromium: 12 mcg – A trace mineral, chromium is a widely-used supplement which is only required in small amounts. Chromium is involved in fat, protein, and carbohydrate metabolism and is known to improve the action of insulin, a hormone critical for metabolic processes and nutrient storage.14

Electrolytes – Chloride, Sodium and Potassium: 170 mg – Chloride, sodium and potassium are three minerals, or electrolytes found in blood and other fluids of the human body that carry an electric charge.15

Electrolytes affect important processes such as muscle function, blood acidity and the amount of water in your body. Electrolytes maintain fluid balance within the body and are sweat out during physical exercise.15

Calcium, magnesium and phosphorus are also considered electrolytes.

Branched Chain Amino Acids: 2 g – According to the Myprotein website, Mypre includes 2 g of BCAA in a 2:1:1 ratio. The label also separately reports the three branched chain amino acids, providing some confusion for readers.

The official website reports they’ve added an additional 800 mg (400 mg per serving) of leucine on top of this ratio to support muscle protein synthesis. Evaluating the numbers, we assume Myprotein has also included more valine and isoleucine to the formula, to nearly double this 2:1:1 ratio.

L-Leucine: 424 mgL-leucine is one of three essential branched chain amino acids (BCCAs) that must be consumed through diet or supplements. Branched chain amino acids promote muscle-protein synthesis, increased muscle mass and decrease muscle damage, as well as delay fatigue.16

For increased benefits, L-leucine should be combined with other branched chain amino acids such as L-valine or L-isoleucine.16 In Mypre Pre Workout, L-leucine is combined with L-isoleucine and L-valine in a near 2:1:1 ratio.

L-Valine: 283mg – The second BCAA, L-valine helps promote muscle growth and repair and supports the other two BCCAs. Valine has rarely been tested in isolation but so far, has not demonstrated any unique benefits on body composition.17

L-Isoleucine: 217mg – An isomer of leucine, L-isoleucine has a wide range of functions such as contributing to wound healing, hemoglobin synthesis, regulating energy levels, stimulating the immune system and signaling the secretion of several different hormones.23

L-Citrulline DL-Malate: 1.5g – Commonly used in sports performance, the amino acid L-citrulline helps delay fatigue, maintain blood pressure, promote energy, and endurance. L-citrulline helps deliver energy to the muscles, synthesizes proteins and increases levels of muscle protein.18

Beta Alanine: 1.5gAs a modified version of the amino acid alanine, beta alanine has been clinically shown to improve muscular endurance. Beta alanine is a precursor to carnosine, an antioxidant molecule that works to buffer lactic acid buildup within the muscles. It also contributes to gaining lean muscle mass.19

In a meta-analysis of clinical trials, beta alanine has been shown to improve endurance by a median 2.5% in moderate to high aerobic activities.19 When combined with L-Histidine (as it is in this formula) beta alanine converts into carnosine in the body.

Studies have shown that the minor testosterone boost caused by taking D-aspartic acid may last 6-12 days in normal men, or up to a 30-60% serum testosterone concentration boost in infertile males. These raised levels of testosterone will normally return to baseline levels within 1-2 weeks of supplementation.20

D-Aspartic Acid: 1.5g – As one of two possible forms of the amino acid aspartic acid, D-aspartic acid’s (DAA) primary benefit is the ability to temporarily boost testosterone amongst the infertile and also male athletes. DAA operates in the brain and causes an increased secretion of growth hormone, luteinizing hormone and follicle-stimulating hormone.20
L-Arginine: 686mg – Classified as a conditionally essential amino acid, L-arginine can be obtained through food sources or supplementation. Arginine is directly responsible for nitric oxide activity (blood flow) and increased vasodilation (widening of blood cells) and is used to increase blood flow for conditions such as heart disease or erectile dysfunction.21

In the body, arginine also triggers protein production and has been noted to promote wound healing.21

In a 2014 clinical study, pre-exercise L-arginine supplementation was shown to increase time to exhaustion in competitive male wrestlers. The trial was based on a single-dose of 1.5 g · 10 kg-1 and measured the effects of arginine on time to exhaustion, heart rate and lactate levels when athletes underwent exhaustive exercise bouts.22

L-arginine, an ingredient in Myprotein Mypre pre workout, helps prolong time to exhaustion
A one-time dose of L-arginine prolonged time to exhaustion by 5.8% in male wrestlers.

Results indicate that when compared against a placebo, arginine prolonged the time to exhaustion by 5.8%. While heart rate and lactate levels did not reach significance, arginine remains one of the most popular ingredients in ergogenic aids.22

L-Arginine Alpha-Ketoglutarate: 500 mg – L-arginine alpha-ketoglutarate (AKG) is a combination of the salt from amino acids combined with the nitrogen-free component of glutamine. AKG is formed in the Krebs (energy-producing) cycle and is critical for healing muscle tissue. When administered through an intravenous, AKG prevented a decline in protein synthesis in post-surgery patients.24

Due to these clinical findings, L-Arginine and AKG combined and together are thought to increase available energy, improve blood flow and enhance muscle mass.24,25

Betaine Anhydrous: 500 mg – Betaine anhydrous, also referred to as betaine or trimethylglycine (TMG), is a naturally occurring substance that plays a role in cellular reproduction, carnitine production and liver function. This substance also helps metabolize certain amino acids.26

Creatine Hydrochloride, Monohydrate and Ethyl Ester Hydrochloride: 1500 mg – Mypre pre workout formula includes 500 mg of Creatine Hydrochloride, Monohydrate and Ethyl Ester hydrochloride each.

Creatine is a molecule that is commonly known to rapidly increase energy production and contains performance-enhancing properties.

Creatine monohydrate is the most popular and most potent form of creatine. Known for its ergogenic (performance-enhancing) properties, it’s often used in clinical trials. According to a meta-analysis of clinical trials, creatine monohydrate is able to increase a 12% improvement in strength to 20%.27

Both creatine hydrochloride and creatine ethyl ester hydrochloride are known to dissolve faster in the intestines than creatine monohydrate, reducing stomach cramping. Creatine ethyl ester hydrochloride allows for nearly 99% absorption in the body.28

When combined with a resistance training program, consuming creatine in doses of at least 3 grams can increase power output, strength, lean muscle mass and performance in anaerobic exercises.27 Taking two servings of Mypre can achieve this dosage.  

L-Lysine: 326 mg – An essential amino acid, L-lysine or lysine, must be consumed through diet or supplementation. Lysine acts as a building block of protein and is important for proper growth and the formation of collagen, a substance important for maintaining connective tissues surrounding joints.29

Some studies suggest that lysine contributes to muscle tissue recovery after exercise-induced damage.29

Caffeine (including Guarana Extract 12%): 200 mg – As the number one consumed stimulant, caffeine has been shown to increase endurance, speed and body coordination during physical activity. Caffeine also delays fatigue and decreases the perception of pain which may allow for training at higher intensities for extended periods of time.30,31

Studies have shown that 200-350mg of caffeine supplementation can increase endurance. This may be caused by the body using fat as fuel rather than glycogen stores.30

Guarana Extract 12%: 100 mgOriginating from Northern Brazil, guarana is a south American plant that contains naturally occurring caffeine. Known for its stimulant properties, guarana has been claimed to enhance cognitive performance and improve fat metabolism but research is still ongoing.32

L-Threonine: 163 mgL-threonine is a lesser known essential amino acid which contributes to the formation of collagen, enamel and elastin protein. Threonine also helps the central nervous system, fat metabolism in the liver and maintains digestive tract functionality. This amino acid has also been used to reduce symptoms of anxiety and depression.33

L-Phenylalanine: 136 mg – Classified as an essential amino acid, phenylalanine plays a critical role in amino acid biosynthesis. This amino acid also assists in the functions and structures of numerous enzymes and proteins. It is a precursor of dopamine, which regulates movement and emotional responses such as rewards and pleasure.34,35

L-Methionine: 113 mgL-Methionine is a sulfur-containing essential amino acid required for tissue development and repair. It is also critical for the absorption of trace minerals zinc and selenium and is used in several detoxifying processes.36

L-Histidine: 108 mg – A semi-essential amino acid, L-histidine is required for protecting nerve cells, tissue repair and growth. Histidine is metabolized into the neurotransmitter histamine which plays an important role in sexual functions, the immune system and protects against tissue damage.37

L-Tryptophan: 44mg – In adults, L-tryptophan is important for nitrogen balance (protein utilization) and is a precursor to serotonin. A biochemical messenger, serotonin is an important neurotransmitter that regulates hemostasis and maintains cardiovascular integrity.38

Tryptophan is a naturally occurring sedative that may help balance out, or ‘take the edge’ off stimulants such as caffeine.


For best results, mix one scoop of Mypre pre workout with 10-17 oz of cold water depending on your desired sweetness. Consume the mixture 30 minutes before exercise from a glass or shaker cup. Supplement Analysts suggests starting with ½ to one scoop to assess your tolerance.

Side Effects

While the ingredients used in Mypre are all regarded as safe, minor side effects may still occur.

Those sensitive to caffeine may want to start with a ½ a dose to reduce possible side effects such as nervousness, jitteriness or irritability. Due to the amount of caffeine per serving, Mypre pre workout should not be taken within four hours of going to bed. For those that train in the evening, this product may delay fatigue.

Creatine may cause stomach cramping, but the addition of more water-soluble forms will help reduce this effect in some people. Nausea and diarrhea may occur when too much creatine is taken at once. To reduce these side effects, consume with the recommended amount of water and spread doses out.27

The presence of electrolytes will also help keep you hydrated, maintain fluid balance and replace any electrolytes lost through physical exercise.

Mypre also contains 2.4 mg of niacin, which in some users may result in a harmless, temporary flushing sensation known as a ‘niacin flush.’ This normal flush will go away after 1-2 hours.

Projected Results

Based on the active ingredients, a recent user reviews, below are the projected results for Myprotein Mypre Pre Workout.

One scoop of Mypre contains 200mg of caffeine per serving. Compared to other product we’ve reviewed, 200mg falls in the middle of caffeine doses but is the same effective dose used in clinical trials. This combination of caffeine and guarana extract is enough to boost endurance, keep you mentally alert and dialed in to your workout.

With 1.5 grams of Beta alanine per serving, users may experience an increase in performance time from 60-240 seconds and additional 1-2 reps when training in sets of 8-15 repetitions.20

The Mypre formula contains a large variety of amino acids that act as the building blocks for protein and will help protect and repair exercise-induced damage in connective tissues.

The multiple B-complex vitamins will aid muscle contraction, nerve function, fat and protein metabolism.

Three different types of creatine are included in this formula to enhance pumps in the gym, and promote muscle growth. Combined, they total 1.5 g which falls 0.5 g short of the recommended dose of 2-5 g to maintain body composition. According to Health Canada, the ideal dose for athletes in a loading phase ranges between 3-5 g per day.

Final Review

Ingredients & Nutritional Profile: 8.9 / 10
Taste / Mixability: 8.7 / 10
Manufacturing: N/A
Value: 9.3 / 10
Final Rating:

For delivering diverse nutritional profile, containing a good number of stimulants and maintaining an affordable cost per serving, Mypre Pre Workout earns a 9.0/10.

In terms of ingredients and nutritional profile, Mypre garnishes a 9.0/10. While this formula includes three different sources of creatine, it tops up at 1.5 grams total, which is less than the recommended dose to increase muscle mass. The total creatine amount is less than other pre workouts we’ve seen on the market and lost points for Mypre.

However, we do like that Mypre offers several amino acids that act as fuel for muscle and promote protein synthesis. With 200mg of caffeine per serving, Mypre provides users with a good amount of caffeine to increase energy and endurance.

Minor points were lost for taste and mixability as some readers have commented that Mypre containers have arrived with several solid clumps and certain flavors may be strong. While we didn’t experience this with our product, Supplement Analyst values the feedback we get from our readers.

We recommend Mypre for users looking for a great value pre workout, that offers a bonus of numerous vitamins and amino acids.
