Uses & Effectiveness
Insufficient Evidence for
- Muscle strength. Taking D-aspartic acid does not seem to improve muscle strength in trained male athletes. The effect of D-aspartic acid in untrained athletes or women is not known.
- Athletic performance.
- Fatigue.
- Increase absorption of minerals.
- Withdrawal from heroin, morphine, and other opioid drugs.
- Other conditions.
Side Effects & Safety
When taken by mouth: Aspartic acid is LIKELY SAFE when consumed in food amounts. Aspartic acid is POSSIBLY SAFE when taken for a short time. There isn't enough reliable information to know if aspartic acid is safe when used long-term or what the side effects might be.Special Precautions & Warnings:
Pregnancy and breast-feeding: Aspartic acid is LIKELY SAFE when consumed in food amounts. It is POSSIBLY UNSAFE when taken as a supplement during pregnancy or while breast-feeding. Aspartic acid supplements have been linked to possible brain defects in newborn infants in animal research. Don't use aspartic acid supplements if you are pregnant, trying to become pregnant, or breast-feeding.Children: Aspartic acid is POSSIBLY UNSAFE when given by mouth to infants. It has been linked to possible brain defects in animal research. Don't give aspartic acid supplements to infants. There isn't enough reliable information to know if aspartic acid supplements are safe in older children and adolescents or what the side effects might be. Stay on the safe side and avoid use.
Interactions
We currently have no information for ASPARTIC ACID Interactions.
Dosing
The appropriate dose of aspartic acid depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for aspartic acid. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
