ASPARTIC ACID

OTHER NAME(S):

Acide Aspartique, Acide L-Aspartique, Asp, Aspartates, Aspartatos, Aspartic Acid, D-Asp, D-Aspartic Acid, L-Asp, L-Aspartate, L-Aspartic Acid, Magnesium Potassium Aspartate, Spartase.<br/><br/>

Overview

Overview Information

Aspartic acid is a type of amino acid. Amino acids are typically used as building blocks to make protein in the body. One type of aspartic acid, called D-aspartic acid, is not used to make protein but is used in other body functions.

Aspartic acid is commonly used to reduce feelings of tiredness, improve athletic performance, and increase the size and strength of muscles. But there is limited scientific research to support these uses.

How does it work?

There isn't enough information to know how L-aspartic acid works. D-aspartic acid might increase levels of the chemical testosterone in the body.

Uses

Uses & Effectiveness?

Insufficient Evidence for

  • Muscle strength. Taking D-aspartic acid does not seem to improve muscle strength.
  • Increasing mineral levels.
  • Enhancing athletic performance.
  • Reducing tiredness.
  • Other conditions.
More evidence is needed to rate the effectiveness of aspartates for these uses.

Side Effects

Side Effects & Safety

Aspartic acid is LIKELY SAFE when consumed in food. However, it is not known if aspartic acid is safe when used as medicine.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Not enough is known about the use of aspartates during pregnancy and breast-feeding. Stay on the safe side and avoid use.

Interactions

Interactions?

We currently have no information for ASPARTIC ACID Interactions.

Dosing

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.
