Science, simplified for you.

Based on a rigorous study of the scientific evidence and not on the latest dietary fad, Rhitrition+ offers a traceable, rigorously researched alternative to traditional supplements, including an easily absorbable oral spray, drops for children, and multivitamins that have confidence in every capsule. Our range has been developed by harnessing founder and nutritionist Rhiannon Lambert’s clinical experience at Rhitrition, her Harley Street practice.
