Green Coffee Bean Extract in Sodaslim: What the Evidence Really Says

Quick answer

The best summary of green coffee bean extract is a 2011 meta-analysis of three small trials: people lost about 2.47 kg more than on placebo, but all three trials were poor quality. One study behind the hype led to an FTC settlement. Trials used 180-200 mg a day; Sodaslim has 130 mg.

Pale green unroasted coffee beans with fresh coffee leaves — Green coffee extract comes from beans that were never roasted. Sodaslim lists 130 mg of extract, standardized to 50% chlorogenic acids.

The short answer

Does green coffee bean extract help with weight loss?

Maybe a little, but nobody can say for sure. The few trials that exist pointed to a small loss, and every one of them had serious flaws.

Sodaslim lists 130 mg of green coffee bean extract (Coffea robusta seed, 50% chlorogenic acids) in each capsule. That is about 65 mg of chlorogenic acids. It is one of five printed amounts on the Sodaslim label.

The NIH Office of Dietary Supplements says green coffee "might help you lose a small amount of weight" (NIH ODS: Weight-loss supplements (consumer)). That careful wording is a fair place to start.

The ingredient

What is green coffee bean extract?

It is an extract of coffee beans that have not been roasted. Raw beans are rich in chlorogenic acids, a family of plant compounds that roasting partly breaks down.

Researchers have looked at these acids as a possible aid to weight control. Interest is not the same as proof in people, though. Only human trials can answer that.

Green coffee extract also contains some caffeine (NIH ODS: Weight-loss supplements (HP)). The Sodaslim label does not state how much comes from this ingredient, so the capsule's total of about 140 mg is an estimate. The green coffee bean ingredient page has the full profile.

The meta-analysis

What did the green coffee meta-analysis find?

It found about 2.47 kg (5.4 lb) more weight loss than placebo, pooled from just three trials. Onakpoya and colleagues published it in 2011 (Onakpoya 2011: Green coffee meta-analysis). They found five eligible trials and could include only three.

Trials found	5 eligible
Trials included	3
Risk of bias	High in all three
Average extra loss vs placebo	2.47 kg
Range of likely effect	0.72 to 4.23 kg
Results between trials	Varied a lot (significant heterogeneity)
Authors' view	"Promising", but poor quality; better trials needed

The trials lasted 4 to 12 weeks and used 180 to 200 mg of extract a day (NIH ODS: Weight-loss supplements (HP)). Short, small and flawed trials can make a weak effect look bigger than it is.

Why it matters

Why were the green coffee trials called poor quality?

All three had a high risk of bias, meaning the way they were run could have skewed the results. The authors themselves said the evidence was not strong enough to rely on (Onakpoya 2011: Green coffee meta-analysis).

Very few people

Small groups make chance results more likely. One unusual person can move an average.

Short follow-up

A few weeks says nothing about whether weight stays off over a year.

Results disagreed

The trials did not line up well, which weakens any single pooled number.

The FTC says health claims need competent and reliable science, ideally randomized trials that match the product (FTC: Health products compliance). Three shaky trials of a different dose fall short of that bar.

The FTC case

What was the FTC green coffee case about?

In 2014, the Federal Trade Commission settled with Applied Food Sciences, a green coffee supplier, over a study the agency called "hopelessly flawed" (FTC: Green coffee study case). The company agreed to pay 3.5 million dollars.

The study ran in India in 2010. According to the FTC, weights were altered, the trial length was changed and the placebo assignment was misstated (FTC: Green coffee study case).

The famous claim

Marketers said people lost 17.7 lb and 16% of body fat in 22 weeks "without diet or exercise". The FTC said participants had in fact been told to diet and exercise (FTC: Green coffee study case).

The settlement requires at least two well-controlled human trials for any future weight-loss claims from that company. The NIH notes that one trial was retracted after the FTC action (NIH ODS: Weight-loss supplements (HP)). Much of the early green coffee buzz rested on that study.

The dose

Is 130 mg of green coffee extract enough?

It is below what the trials used. Studies gave 180 to 200 mg of extract a day (NIH ODS: Weight-loss supplements (HP)); Sodaslim has 130 mg, roughly two thirds of that range.

Each "Label" bar is drawn to scale against the research dose or daily guideline beside it. All five amounts are printed per 1-capsule serving; percentages come from the label's own standardization. Raspberry ketone is left out because no human study tested it alone. Studies tested each ingredient alone, not Sodaslim.

Extracts can also differ in strength, so milligrams of one product may not match another. Sodaslim's is standardized to 50% chlorogenic acids, printed on the label.

Being under the trial dose has an upside. The NIH consumer fact sheet says green coffee extract seems safe up to 200 mg a day for 12 weeks (NIH ODS: Weight-loss supplements (consumer)), and 130 mg sits inside that.

Safety

Does green coffee extract have side effects?

Mild ones were reported. Headache and urinary tract infections came up in the trials, the NIH says (NIH ODS: Weight-loss supplements (HP)).

The larger issue in Sodaslim is caffeine. Each capsule has 138 mg of caffeine anhydrous plus a little more from the extracts. Stack it with coffee and the total adds up. The FDA says healthy adults can usually have up to 400 mg a day (FDA: How much caffeine is too much).

Too much caffeine can cause jitters, poor sleep and a fast heartbeat. Chest pain, a racing or irregular heartbeat, or fainting needs a doctor right away.

The verdict

How should you weigh green coffee extract in Sodaslim?

Treat it as a small extra, not the reason to buy. The research is thin, the dose is lower than studied, and the best-known study collapsed.

Every amount is printed, so you can see exactly what you get.
No trial has tested Sodaslim itself.
Caffeine is the ingredient with a measurable effect on calorie burn, and it is small.
Steady loss comes from eating and activity: about 1 to 2 lb a week, the CDC says (CDC: Steps for losing weight).

FAQ

Green coffee bean extract: questions

Is the green coffee bean extract in Sodaslim enough to work?

Probably not on its own. Trials used 180-200 mg of extract a day (NIH ODS: Weight-loss supplements (HP)), and Sodaslim has 130 mg. Even at trial doses, the three studies were poor quality, so the true effect is unclear.

How much weight can green coffee bean extract help you lose?

A 2011 meta-analysis found about 2.47 kg (5.4 lb) more loss than placebo, but from only three flawed trials (Onakpoya 2011: Green coffee meta-analysis). The real figure could be smaller. The NIH calls it a possible small loss.

Was green coffee bean extract a scam?

The best-known study was. The FTC called one 2010 study hopelessly flawed and settled with the supplier in 2014 (FTC: Green coffee study case). The extract itself is a real ingredient with weak, uncertain evidence behind it.

Who should avoid green coffee bean extract?

Anyone who must limit caffeine, and everyone the label excludes: people under 18 and pregnant or nursing women. Green coffee contains some caffeine (NIH ODS: Weight-loss supplements (HP)), and Sodaslim adds 138 mg of caffeine anhydrous on top.

Is green coffee bean extract safe to take every day?

At moderate doses it seems safe for most adults for up to 12 weeks, per the NIH consumer fact sheet (NIH ODS: Weight-loss supplements (consumer)). Headache was reported. Long-term safety is not well studied.

Does the 2.47 kg green coffee result apply to Sodaslim?

No. That figure came from three small trials of green coffee extract alone at 180-200 mg a day (Onakpoya 2011: Green coffee meta-analysis). Sodaslim has 130 mg mixed with four other ingredients, and no trial has tested Sodaslim itself.
