Overview Information

Aspartate is a vitamin-like substance called an amino acid. As a dietary supplement, aspartate is combined with minerals and is available as copper aspartate, iron aspartate, magnesium aspartate, manganese aspartate, potassium aspartate, and zinc aspartate.

Aspartates are used to increase absorption of the minerals they are combined with and to enhance athletic performance. Some forms are used to reduce brain damage caused by cirrhosis of the liver (hepatic encephalopathy) when given intravenously by a healthcare professional.

How does it work?

There isn't enough information to know how aspartates work.


Uses & Effectiveness?

Insufficient Evidence for

  • Liver cirrhosis. Developing research suggests L-ornithine-L-aspartate given by IV (intravenously) might reduce brain damage in some patients with liver cirrhosis.
  • Enhancing athletic performance.
  • Increasing mineral levels. So far there is not evidence that aspartates increase mineral absorption. Except in cases of mineral deficiency, such as iron-deficiency anemia, a well-balanced diet typically provides the recommended daily allowance (RDA) of minerals.
  • Other conditions.
More evidence is needed to rate the effectiveness of aspartates for these uses.

Side Effects

Side Effects & Safety

It is not known if aspartates are safe.

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.



We currently have no information for ASPARTATES Interactions.



The appropriate dose of aspartates 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 aspartates. 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.
