Rapa and grapefruit juice

I believe many members are taking this combination, but I wonder how much juice they take, do they take it at the same time as the rapa, how do we think it affects the dosage, how about other alternatives such as having some oily fish at the same time as the rapa?

Hoping someone can help out with advice on this.


Hi Richard. This has been discussed a lot on the past. I recommend you start with this thread:

Here: Rapamycin and Grapefruit Juice

Here: Grapefruit interaction with longevity meds?

and then review the search results on our site for “grapefruit”, and you’ll find a lot of discussions on issues related to the use of grapefruit juice (GFJ). The search button is the magnifiying glass in the upper right corner of the website.
