Yes, amino acids do expire. While they may not become immediately harmful after the expiration date, their potency and effectiveness decrease over time. This means you may not receive the full benefits advertised on the product label.
Understanding Amino Acid Expiration Dates
The expiration date printed on amino acid supplements signifies the manufacturer's guarantee of full potency and quality. After this date, the product's effectiveness might diminish, although it may not necessarily become unsafe. Several factors contribute to this degradation. Exposure to heat, light, and moisture can accelerate the breakdown of amino acids, reducing their efficacy.
Several sources confirm this:

Practical Implications
- Reduced Effectiveness: The primary concern with expired amino acids is a loss of effectiveness. You might not see the desired results from your supplement.
- Potential for Contamination: Although less likely, the risk of bacterial or fungal contamination increases with time, especially if storage conditions are not ideal.
Recommendation
Always check the expiration date on your amino acid supplements and discard them after the date has passed. While they might not immediately become hazardous, their effectiveness will likely be compromised.
