Hormonal

Daily supplementation with 300 mg of Palmitoylethanolamide (PEA) combined with 8 weeks of resistance training does not improve upper-body maximal strength (1-RM bench press) compared to placebo.

Do not take PEA expecting to get stronger. The study found that people taking the placebo actually got slightly stronger in their bench press than those taking PEA. PEA is useful for pain and power, but not for maximal strength.

GoodRefutesHIGH confidence
The PLA group had higher 1‑RM bench press post‑intervention compared with the PEA group (ITT: 2.24 kg [0.12, 4.37] p = 0.039; PP: 2.73 kg [0.40, 5.06] p = 0.023).
