Summary of Raspberry Ketone
Primary Information, Benefits, Effects, and Important Facts
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.

Recommended dosage, active amounts, other details
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.

Human Effect Matrix
The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what effects raspberry ketone has on your body, and how strong these effects are.
|Grade||Level of Evidence [show legend]|
|Robust research conducted with repeated double-blind clinical trials|
|Multiple studies where at least two are double-blind and placebo controlled|
|Single double-blind study or multiple cohort studies|
|Uncontrolled or observational studies only|
Level of Evidence
? The amount of high quality evidence. The more evidence, the more we can trust the results.
Magnitude of effect
? The direction and size of the supplement's impact on each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect.
Consistency of research results
? Scientific research does not always agree. HIGH or VERY HIGH means that most of the scientific research agrees.
