Raspberry ketone is the compound responsible for many flavoring and aromatic qualities of cosmetics and processed foods.
It should be noted that all evidence for the effects of raspberry ketone has only been observed in vitro (in a test tube). Though researchers are able to raise the concentrations of ketones in a single cell during studies, these same concentrations cannot be replicated in the human body, particularly through oral supplementation.
- 4-(4-hydroxyphenyl) butan-2-one
- p-hydroxybenzyl acetone
- Ketone Monoester
- Ketone Diester
- Ketone Salts
There is no human evidence for the effects of raspberry ketones. Studies on rats have used a dosage range of .545-2.18g/kg, which correlates to a human estimated dose of 80-340mg/kg for humans. This dose is very high compared to other fat burning compounds, so for that reason the standard supplemental dose of raspberry ketones for humans is in the 100-200mg range. There is no solid evidence for the effectiveness of the doses listed below. Rat dosages correlate to the following human doses:
- 870-3,700mg for a 150lb person
- 1,100-5,000mg for a 200lb person
- 1,500-6,200mg for a 250lb person
There is no human evidence for the effectiveness of raspberry ketones. Raspberry ketones cannot be concentrated in the human body the same way they are concentrated during studies done outside the body, on single cells.
