What Is HCA (Hydroxycitric Acid) in Garcinia Extract?
HCA, or hydroxycitric acid, is the acid in the rind of the garcinia fruit that extracts are standardized to. SodaSlim lists 130 mg of garcinia extract at 50% HCA, so a capsule holds about 65 mg of it. A pooled review found a difference of 0.88 kg against placebo, which its authors called small.

What is HCA in garcinia?
HCA is hydroxycitric acid, the compound that garcinia cambogia extracts are measured by. It comes from the fruit rind of the plant.
The SodaSlim label reads "Garcinia Extract (Garcinia cambogia)(fruit)(50% HCA)". Half of the extract by weight is HCA, and that percentage is what lets two bottles be compared.
SodaSlim is a capsule, not a drink. This line is one of five in it.
How much HCA is in one SodaSlim capsule?
One capsule holds about 65 mg of HCA. The label prints 130 mg of extract, and 50% of 130 is 65.
| Item | Amount |
|---|---|
| Garcinia extract per capsule | 130 mg |
| HCA at 50% | About 65 mg |
| Share of the capsule | 19.8% (130 of 658 mg) |
| Per 30-capsule bottle | About 1,950 mg HCA |
| Verified daily study dose | Not found in our sources |
The last row matters. The review we read pooled nine trials, but we did not read their daily HCA doses, so we draw no bar and set no target.
Where does the garcinia line sit next to the rest of the label?
It sits level with three other lines. Garcinia, green coffee, raspberry ketone and green tea extract each print 130 mg, and caffeine prints 138 mg.
The scale below sets the label next to reference amounts for the lines that have one.
Label vs reference amounts
Garcinia has no reference bar, because no verified daily study dose exists in our sources. See the garcinia extract page for the full profile.

See packsDoes HCA work for weight loss?
The effect is small at best. A 2011 meta-analysis found HCA beat placebo by 0.88 kg on average, and its authors called the effect small and its clinical relevance uncertain (Onakpoya 2011, Garcinia (HCA) meta-analysis).
The NIH says garcinia cambogia has little to no effect (NIH ODS, Weight loss supplements (consumers)). The NCCIH says it is unclear whether garcinia products help with weight loss (NCCIH, Garcinia cambogia).
The NCCIH also reports numerous cases of liver toxicity, several severe, and possible interactions with drugs that affect the liver or serotonin (NCCIH, Garcinia cambogia). Ask a doctor or pharmacist first, and keep taking prescribed medicine. Yellow skin or eyes, dark urine or belly pain need care now.

How much HCA is in garcinia cambogia?
It depends on the extract. In SodaSlim the label says 50% HCA of a 130 mg extract, which works out to about 65 mg per capsule. Other products may use another strength, so read the percentage.
