Amino acids are nutrients that make up all the proteins in the body.

What are amino acids and when are they appropriate?

The body obtains amino acids from food and protein products. Individual amino acids or complexes are often chosen as a convenient “pre-workout” format or as a point supplement to the diet — especially during periods of high training volume, a tight schedule, or a calorie deficit.

Quick navigation: BCAA · Arginine · Beta-alanine · Citrulline · Glutamine · Taurine · Glycine · Tyrosine · Tryptophan · Lysine · Methionine · Cysteine · coming soon: EAA · Complex amino acids

• Target selection: endurance, “pump”, recovery, focus
• Formats: powders, capsules, tablets
• Conveniently combines with protein, creatine and electrolytes (if needed)

Subcategories: what for what

• BCAA is a light format before/during training, when you want an “intra” without a heavy shake.
• EAA (coming soon) is a universal complex of essential amino acids when a more “complete” profile is needed.
• Complex amino acids (coming soon) — a selection of complexes where amino acids are combined “for the task.”
• Arginine and citrulline are more often chosen for “pump” and high-intensity training (separately or in complexes).
• Beta-alanine is a popular choice for endurance and high-intensity workouts; it sometimes causes a tingling sensation, which is typical of the ingredient.
• Glutamine is often taken in recovery programs, especially during periods of high exertion.
• Taurine is a versatile ingredient often used in sports programs; convenient in powder/tablet form.
• Glycine and tryptophan are more often considered for evening mode and relaxation (without stimulants).
• Tyrosine is a popular choice for focus/productivity (before work or training).
• Lysine , methionine , cysteine — “point” amino acids: appropriate when a specific component is needed.

How to choose for your purpose

• Endurance and volume work: beta-alanine + convenient “workout” format.
• “Pump” and muscle feel: citrulline or arginine (or complexes).
• Recovery during difficult periods: glutamine + control of the total protein intake in the diet.
• Focus/performance: Tyrosine as a spot-on option.
• Evening regimen: glycine or tryptophan (without stimulants).

FAQ

BCAA or EAA?

If you need a broader amino acid profile, you often choose EAA. If you need a simple “intra” format, you choose BCAA.

Do I need amino acids if I drink protein?

Not always. Protein often covers the need for amino acids. Individual amino acids are a convenience and targeted support for the task.

Can I combine several products?

Yes, but check the compositions of the complexes so as not to duplicate the same components, and don't do "everything at once" - it's better to use 1–2 products for a specific purpose.
