What Are Amino Acids?
Amino acids are organic compounds that occur naturally in food proteins and are commonly described as the building blocks of protein. In food supplements, amino acids are also supplied individually as free-form nutritional ingredients.
Amino acids are generally classified as essential, non-essential, or conditionally essential. When supplied in supplements, they are regulated as food ingredients rather than medicines.

Free-Form Amino Acids in Food Supplements
Free-form amino acids are isolated compounds supplied independently rather than as part of whole proteins. They are commonly produced using microbial fermentation or controlled synthesis.
Examples commonly used in UK food supplements include:
- L-Theanine
- L-Tyrosine
- Glycine
- Taurine

Measurement & Accuracy
Accurate measurement is essential when handling amino acid powders. Many powders are fine and concentrated, requiring suitable digital scales designed for small quantities.
Capsule products remove the need for manual measurement but offer less flexibility than powders.
Manufacturing & Quality Standards
Most amino acids used in UK food supplements are produced using fermentation or controlled synthesis. Quality assurance typically includes identity testing, purity verification, and batch traceability.

UK Regulation & Safety Context
Amino acids supplied as food supplements in the UK fall under general food safety legislation and must not be marketed as medicinal products.
Regulatory guidance: UK Food Standards Agency – Food Supplements
Caffeine & Amino Acids
Some food supplements combine amino acids with caffeine. Caffeine requires clear labelling and appropriate safety warnings due to its concentrated nature.
