Brief summary

The aim of this study is to assess the effect of orally-dosed palmitoylethanolamide (PEA) on allergy symptoms in otherwise healthy young males and females aged over 18 years compared to a placebo. This is a double-blind, randomised, clinical trial with a 2-week treatment duration with 2 arms. It is hypothesised that PEA supplementation over a period of 2 weeks will reduce the severity of allergy symptoms compared to the placebo.

Each product will be consumed as per the following: Two capsules containing a total 350 mg of PEA with LipiSperse™ and maltodextrin taken daily in the morning for 2 weeks.
