Vikifun Aminobutyric acid
[Vikifun Aminobutyric acid]

My son’s growth spurt started 3 weeks after starting this lysine! He’s proud to reach the top pantry shelf, and his pediatrician praised his development. Gentle on his sensitive stomach, and the brand is upfront about what’s in the bottle. I’ve repurchased twice and told my daughter’s teacher; she recommended it to her own kids!
