HCA

How You May Benefit:

Block fat storage
Suppress fatty acid mobilization, blocking the conversion of carbohydrates to fat, resulting in less fat storage
Suppress appetite
Support weight loss as a natural appetite suppressant—reducing the urge to overeat

Overview

Although the debate regarding the potential benefits of HCA is ongoing, that doesn't mean we have to ignore its documented potential to help block the conversion to and storage of fat—leading to accumulation—or its influence on appetite suppression. These effects may make HCA a worthwhile choice as a natural weight-loss aid.

Usage

Amount:

The suggested amounts range from 1,500 to 3,000 mg per day, divided in 3 doses.

Studies typically use 1,500 mg (as hydroxycitric acid or HCA), divided in 3 doses throughout the day.

Timing: HCA should be taken about 30 minutes before meals and should not be consumed with high-fiber supplements or meals because this may reduce its effectiveness.

Tip: Check the actual milligrams of hydroxycitric acid (HCA) on the label if using a standardized extract form of Garcincia cambogia. It should contain at least 50% extract (e.g., a 50% extract of 500 mg Garcincia cambogia would yield approximately 250 mg of HCA).

Active individuals use HCA to both support fat loss and increase energy levels and because, unlike many other weight-loss or stimulant products, HCA doesn't cause negative side effects, such as the jitters. But that doesn't mean it's a miracle worker. In fact, claims for how (and even if) it works are still hotly debated. Critics profess that further studies need to be conducted on humans, while proponents of this "fat-loss" aid stand by their animal research. So, the jury is still out on this one, but it might be worth a try regardless.

Safety Information

If you are pregnant or lactating, HCA is not recommended.
