Potential Risks of BCAA Supplements

Side Effects of BCAAs

Branced-chain amino acids (BCAAs) are commonly used to support muscle growth and reduce muscle soreness and fatigue after exercise. When taken orally within recommended dosages, BCAAs are generally considered safe; however, they may cause certain side effects, such as fatigue, digestive issues including nausea, vomiting, diarrhea, bloating, elevated blood pressure, headaches, or in rare cases, changes in skin color.

Precautions for Using BCAAs

There are several precautions associated with BCAA use, including the following:

• Pregnancy and breastfeeding: There is insufficient evidence to confirm the safety of BCAAs during pregnancy and lactation, so it is advisable to avoid them during these periods.
• ALS patients: Individuals with amyotrophic lateral sclerosis (ALS) are advised against using BCAAs, as their use has been linked to respiratory failure and increased mortality rates in affected individuals.
• Maple syrup urine disease: Excessive intake of BCAAs can trigger seizures and lead to severe intellectual and physical developmental delays in people with maple syrup urine disease; therefore, BCAAs should not be used by those with this condition.
• Surgery: BCAAs may affect blood sugar levels, potentially interfering with glucose control during and after surgery. It is recommended to discontinue use at least two weeks before any scheduled surgical procedure.

Recommended BCAA Dosage

A daily intake of 5–12 grams of BCAAs is sufficient for most individuals and can typically be obtained through diet. However, athletes may benefit from dietary supplements that provide approximately 10–20 grams per day.
