yes it probably is safe. that said i want to add if you're taking raspberry ketones for weight loss you need to know there is absolutely no scientific evidence (studies) to support the claim that raspberry ketones cause weight reduction in adults. because raspberry ketones aren't well-studied in humans it's impossible to say for certain if the product will negatively interact with st. john's wort. also be sure to read the raspberry ketones label carefully to determine whether or not the supplement contains any other active ingredients. hope this helps!
is it safe to take take raspberry ketones and saint john's wort together?
