Misleading advertising
I've just stumbled on an advert for this on Facebook suggesting that it can replace methylphenidate. The fact that I'm the first person to write a trust pilot review on this adds more evidence that this looks to be another snake oil peddler trying to take advantage of people with a disability that makes them more susceptible to such scams.
The active ingredients mostly don't have any research to suggest they're helpful for ADHD. We've got Gingko biloba which may be helpful but the research told us that it is significantly less effective than methylphenidate so very much not a replacement. Lemon balm we have some research for children with sub-clinical symptoms so weren't on medication and they experienced some benefit.
A general rule of thumb is that if they infer it can do a similar job as ADHD medication is to ignore it because the only thing that follows will be lies. At best this is a product intended as a nootropic for neurotypical people and at worse it's a grey market scam pretending that the supplement is intended for people with ADHD.
