HYDROXYCITRIC ACID

OTHER NAME(S):

1,2-Dihydroxypropane-1,2,3-tricarboxylic acid, HCA, Hydroxycitrate.

Overview

Overview Information

Hydroxycitric acid is a chemical that is found in fruit rinds of Garcinia cambogia, Garcinia indica, and Garcinia atroviridis. It can also be found in parts of the flowers of Hibiscus subdariffa and Hibiscus rosa-sinensis plants. It is similar to the chemical citric acid.

Hydroxycitric acid is used to improve exercise performance and weight loss.

How does it work?

Hydroxycitric acid might improve weight loss by preventing fat storage and controlling appetite. It might improve exercise performance by limiting the use of stored energy in the muscles, which seems to prevent fatigue.

Uses

Uses & Effectiveness?

Insufficient Evidence for

  • Exercise performance. Taking hydroxycitric acid (HCA) for up to 5 days might increase how long untrained women or elite athletes are able to exercise.
  • Weight loss. The effect of hydroxycitric acid on weight loss is not clear. Some research shows that taking hydroxycitric acid for 8 weeks might improve weight loss. However, other research suggests that it doesn't decrease fat breakdown or energy expenditure in overweight people when taken for only 2 weeks.
  • Other conditions.
More evidence is needed to rate the effectiveness of hydroxycitric acid for these uses.

Side Effects

Side Effects & Safety

Hydroxycitric acid is POSSIBLY SAFE for most people when taken by mouth for 12 weeks or less. Hydroxycitric acid can cause nausea, digestive tract discomfort, and headache when used short-term. Long-term safety is unknown.

Special Precautions & Warnings:

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

Bleeding disorders: There is concern that hydroxycitric acid might slow blood clotting. This might increase the risk of bleeding or bruising in people with bleeding disorders.

Diabetes: Hydroxycitric acid might reduce blood sugar. Monitor blood sugar levels closely. Doses of conventional antidiabetes medications may need to be adjusted.

Surgery: Hydroxycitric acid might affect blood sugar levels and slow blood clotting. This might make it more difficult to control blood sugar and bleeding during and after surgery. Stop taking hydroxycitric acid at least 2 weeks before a scheduled surgery.

Dosing

Dosing

The appropriate dose of hydroxycitric 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 hydroxycitric 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.
