Effects of a Buriti Supplement on Body Composition and Function in Older Adults
2026年8月31日 更新者：Sergio Henrique Sousa Santos、Federal University of Minas Gerais
Effects of "Nutricer®" Vegan Protein Supplementation Based on Buriti (Mauritia Flexuosa), Rice, and Pea on Body Composition, Flexibility, Balance, and Dietary Frequency in Elderly Tai Chi Chuan Practitioners: A Placebo-Controlled Clinical Trial
Aging is a natural process commonly associated with loss of muscle mass, reduced flexibility, and impaired balance, directly affecting the quality of life of older adults.
Tai Chi Chuan, a traditional mind-body practice, has been shown to improve balance, flexibility, and overall well-being in elderly populations.
In addition, nutritional supplementation may enhance these effects, particularly when based on plant-derived functional compounds.This study aims to evaluate the effects of vegan protein supplementation with Nutricer®-based on buriti (Mauritia flexuosa), rice, and pea-on body composition, muscle strength, flexibility, balance, and dietary frequency in elderly women practicing Tai Chi Chuan.
This is a placebo-controlled clinical trial involving 40 elderly female participants, randomly assigned into two groups: an experimental group (n = 20), receiving Nutricer® supplementation, and a control group (n = 20), receiving a placebo (maltodextrin), both alongside regular Tai Chi Chuan practice.Buriti is known for its antioxidant and anti-inflammatory properties, which may contribute to the preservation of muscle and functional health.
It is expected that the combination of vegan protein supplementation and Tai Chi Chuan practice will result in significant improvements in functional health, providing a natural, accessible, and safe strategy for healthy aging.
