SUMMARY: It is our opinion that this probably should be a scam, but we have a lower bar for ingredients you can feel, since you can try them yourself and be the judge. enfinity is the trademark name for paraxanthine, a metabolite of caffeine. The website compares enfinity to caffeine and claims to have all the benefits of caffeine without any of the downsides. However, none of the research directly compares enfinity to caffeine, it's all misdesigned studies against a placebo. The studies were designed to get a positive outcome for marketing claims, not to answer whether enfinity is actually better than caffeine.
enfinity studies have the inventors listed as authors (to their credit, they do disclose this conflict) and a whopping 4 disclosed conflicts of interest, which is actually an impressive number of conflicts. Science without independence is pointless. It's like when the tobacco companies put out human clinical research showing smoking was healthy for you here. The need for independence is so obvious that Dilbert even did a comic about it here. These studies are just an advertisement by the creators in disguise.
We would be very skeptical of enfinity, the reviews from users of the energy drink product on Amazon are very conflicting. Some say it's better, and some still experience the negative effects of caffeine. Maybe try buying one can to see how it works for you before you commit to more.
What is a TLDR review?
A full ingredient review takes weeks to research and weeks to write up as they are 2000–4000 words in length. We love the research part but don't have a full mastery of the English language and loathe the writing. TLDR means "Too long, didn't read". We are going to try doing the same research and just writing a summary. If an ingredient gets enough views, we will expand this to a full write-up. We hope this allows us to give our opinion on more ingredients and prioritize novel new ingredients that just launched.
