Amino Acids: Effects, Benefits, and Products from MST Nutrition

What are amino acids?

Amino acids are the basic building blocks of proteins and are essential for numerous processes in the human body. They are composed of carbon, hydrogen, oxygen, and nitrogen. Some also contain sulfur or selenium. We distinguish between essential amino acids, which must be supplied through diet, and non-essential amino acids, which the body can produce on its own. There are a total of 21 proteinogenic amino acids.

Amino Acid Complex: What are amino acids used for?

1. Muscle Development & Recovery
Essential amino acids, particularly branched-chain amino acids (BCAAs: leucine, isoleucine, valine), are proven to promote protein synthesis and reduce muscle damage. In a meta-analysis, a significant reduction in muscle soreness (DOMS) was observed after taking BCAAs – an average of 33% compared to the control group [1].

2. Energy Production During Sports
Isoleucine and valine contribute to energy production, especially during intense efforts. In a study with trained men, taking 6g of BCAAs before a workout improved physical endurance by an average of 17% compared to the placebo group [2].

3. Strengthening the Immune System
L-glutamine is the most important energy source for immune cells. In 21 martial arts athletes, a daily supplement of 0.3g/kg of glutamine for 3 weeks led to a significant improvement in immune parameters (e.g., sIgA level +35%) and a lower infection rate after intense training [3].

4. Mental Performance
Tyrosine, as a precursor to dopamine and norepinephrine, can improve cognitive performance under stress. In a double-blind study, 2g of tyrosine improved reaction time under cognitive stress by 20% compared to the placebo [4].

5. Wound Healing & Tissue Repair
Arginine and proline are essential for wound healing because they activate collagen synthesis. One study showed that 30 days of daily intake of 9g of arginine in surgical patients accelerated wound healing by 40% [5].

6. Synthesis of Hormones and Enzymes
Threonine and methionine are precursors to enzymes, neurotransmitters, and hormones. In nutritional studies on protein deficiency, targeted supplementation with these amino acids led to a normalization of liver enzymes and an improvement in nitrogen balance [6].

7. Cardiovascular Support
Taurine has been shown to reduce blood pressure. In a placebo-controlled study, daily intake of 6g of taurine for 7 days reduced systolic blood pressure in hypertensive patients by an average of 9 mmHg [7].

8. Skin, Hair, and Nails
Cysteine and glycine are crucial for the formation of keratin and collagen. In a 12-week study, a daily supplement of 500mg of cysteine and 1000mg of glycine significantly improved hair density (+13%) and skin elasticity (+9%) [8].

Amino Acids and the Thyroid Gland

Tyrosine is a component of the thyroid hormones T3 and T4. In studies on latent hypothyroidism, a daily intake of 500mg of tyrosine normalized TSH levels in 34% of patients in 8 weeks [9].

What Amino Acids Does MST Nutrition Offer?

MST Nutrition offers all 21 proteinogenic amino acids:

Essential Amino Acids (EAAs):
Leucine, isoleucine, valine, lysine, methionine, phenylalanine, threonine, tryptophan, histidine

Non-Essential Amino Acids:
Alanine, arginine, asparagine, aspartic acid, cysteine, glutamine, glutamic acid, glycine, proline, serine, tyrosine, taurine

Semi-Essential Amino Acids:
Arginine and cysteine, as their synthesis may be insufficient under conditions of stress and illness.
