Raspberry Ketone: What the Research Says
Published September 30, 2026 · Updated October 02, 2026 · Soda Slim Editorial Verification Desk
Quick answer:
Each capsule has 130 mg raspberry ketone. Evidence comes mainly from rodent and cell studies. Almost no human trials exist, so a weight-loss effect in people is unproven. Treat this ingredient as an unknown, not a proven driver of results.
Evidence ladder for raspberry ketone
| Evidence type | Status |
|---|---|
| Cell (in vitro) | Some activity reported |
| Rodent studies | Reported changes at high doses |
| Human trials, alone | Almost none |
| Human trials, combined formulas | Few, cannot isolate effect |
| Conclusion | Human effect unproven |
What it is
Raspberry ketone is the aroma compound in red raspberries. The amount in real fruit is tiny, so supplements use a concentrated or synthesized form. Soda Slim lists 130 mg per capsule with no standardization percentage, because it is a single compound. See the whole panel in the label breakdown.
It became popular through viral marketing, not through strong clinical results.
Where the claims come from
Early excitement came from lab and rodent experiments in which very high doses relative to body weight changed fat-related markers. Mouse results frequently fail to carry over to people, and the doses used often far exceeded what a capsule provides.
NIH and NCCIH reviews of weight-loss supplements note that there is little to no reliable human evidence for this compound. See NIH ODS.

How to treat it responsibly
- Do not assume it adds benefit; the formula's other effects, mainly caffeine, are better understood.
- Do not take extra raspberry ketone products on top.
- Report any unusual symptoms such as palpitations or jitters; stop and call a doctor if severe. Caffeine, not raspberry ketone, is the likelier cause, see the caffeine article.
What this means for the rest of the formula
If raspberry ketone contributes little in humans, then whatever you notice from the capsule is more likely related to caffeine, with smaller possible roles for green tea catechins and others. That is not a flaw in disclosure; it is exactly what disclosure lets you see. It also means you should not judge the whole product by the marketing of one ingredient.
Ask three questions of any ingredient: is there a human trial, was it independent, and was the dose similar to the capsule? For raspberry ketone alone, the answers are mostly no. For caffeine, the answers are much better, and its effects, including side effects, are well documented.
A fair approach is to try the product for a defined period, keep daily notes, and compare your trend against baseline. If you see nothing, use the guarantee. The daily log helps with this.
One more practical point: because the ketone has no standardization, quality depends on the manufacturer's testing. Soda Slim is made in an FDA-registered cGMP facility in the USA, which describes manufacturing practice, not proof of efficacy.
Bottom line on raspberry ketone
Plain summary: interesting chemistry, unproven in people. Whether it is present at 130 mg or not, your best predictors of progress are still total calories, protein, sleep and daily movement.
Why we say this plainly
This journal covers the evidence as it exists. For raspberry ketone the answer is: promising headlines, thin human data. No supplement replaces nutrition, protein, sleep and movement, and results vary. A 60 day guarantee exists for that reason.

Frequently Asked Questions
Is raspberry ketone proven to burn fat?
No. Evidence is mainly from rodent and lab studies at high doses. Almost no human trials exist, so any weight-loss effect in people remains unproven.
How much is in Soda Slim?
Each capsule lists 130 mg raspberry ketone, one of five actives in a 658 mg total. It is a single compound with no standardization percentage.
Is it the same as eating raspberries?
No. Whole raspberries contain only tiny amounts of the ketone. Supplements use concentrated or synthesized forms, and fruit does not deliver comparable amounts.
