Seven ingredients, one capsule, zero hassle
RETA3 is a food supplement in capsule form: three plant extracts (the “3x G-Formula”), two amino acids and two trace elements – bundled in a vegan HPMC shell.
Instead of juggling several products through the day, you take one standardised capsule: the same amount every day, taste-neutral, easy on the go. Made for adults who like to keep their routine simple.
