Raspberry ketones

Also known as: raspberry ketone, rheosmin

Raspberry ketone is the aroma compound that gives raspberries their smell; in supplements it is almost always synthetic. It is promoted as a fat burner based on cell and animal experiments, while good human studies are lacking.

What it is used for

  • Fat burning and weight loss – no evidence in humans
  • Appetite control – no evidence

Forms and how they differ

single-ingredient capsules

usually a synthetic compound

combined fat burners

often with caffeine and other stimulants, quality depends on the label

When to take it

If at all, with food as per the label.

Pairs well with

No combination is known to give it a proven effect.

Do not combine / separate

Do not combine with stimulants and other fat burners.

Watch out for

Long-term safety is not well studied. Not suitable in pregnancy or while breastfeeding. With heart, kidney or liver disease and when taking medicines (e.g. anticoagulants), consult your doctor.

Safety

Do not exceed the label dose.

Practical tip

This is one of the supplements with the widest gap between marketing and evidence – spend your money elsewhere.
