When to Take Amino Acids


All living things use amino acids, which are molecules used to make protein. Humans need 20 different amino acids to function. That’s because amino acids do so many things for our bodies, including:

  • Helping to break down and digest food
  • Growing and repairing muscle and body tissue
  • Producing hormones and neurotransmitters
  • Providing energy
  • Supporting our immune system
  • Supporting normal digestion
  • Supporting healthy skin, hair, and nails

While we need 20 amino acids, our body only produces 11 of them. The other nine, which are known as essential amino acids, must be derived from other sources, either through diet, supplementation, or both.

Essential and Non-Essential Amino Acids

The 11 amino acids our bodies can produce are known as non-essential amino acids. Those 11 amino acids are:

  1. Alanine
  2. Arginine
  3. Asparagine
  4. Aspartic acid
  5. Cysteine
  6. Glutamic acid
  7. Glutamine
  8. Glycine
  9. Proline
  10. Serine
  11. Tyrosine

Conversely, the nine amino acids our bodies do not produce by themselves are known as the “essential” amino acids. These nine essential amino acids (and some food sources that provide them) are:

  1. Histidine
  2. Isoleucine
  3. Leucine
  4. Lysine
  5. Methionine
  6. Phenylalanine
  7. Threonine
  8. Tryptophan
  9. Valine

A healthy and balanced diet can provide most people the essential amino acids we require. For those who may not get enough amino acids via diet, including vegetarians or vegans, or for those who are looking to further support other health and wellness goals, like better sleep, relaxation, athletic performance, and immune system function, amino acid supplements may be an option.

When to Take Amino Acids

You can and should get many or most of your amino acids throughout the day and by eating a healthy diet. For those taking amino acid supplements to support a particular health goal, such as athletes looking to support performance and muscle growth, you might be wondering if there is a best time to take amino acid supplements.

Research indicates that branched-chain amino acid supplements (BCAAs) may support less muscle soreness and damage following strenuous workouts; help burn more fat during workouts; limit workout fatigue, and reduce delayed onset muscle soreness after a workout.

For these amino acid supplements, which can be taken in powder or capsule form, the ideal time to take them may be up to about 15-30 minutes before beginning a workout. Some amino acid supplements, like leucine, may also be incorporated throughout a work (by mixing the supplement powder with water) to help support optimal muscle gain.

If you are taking amino acid supplements to primarily support fat loss through exercise, you can take the supplement about 30-45 minutes before a meal.

Some high quality amino acid supplements to consider include the three below from Pure Encapsulations, Premier Research Labs, and Metabolic Maintenance.
