Ingestion of a Pre-bedtime Protein Containing Beverage Prevents Overnight Induced Negative Whole Body Protein Balance in Healthy Middle-Aged Men: A Randomized Trial.
Front Nutr
November 2019
Article Synopsis
- Age-related muscle loss can lead to decreased lean body mass and strength, affecting the quality of life in older adults, making nutritional strategies important for prevention.
- The study tested a nighttime dietary supplement with 25 g of milk proteins on middle-aged males to see its impact on whole body protein balance and muscle protein synthesis overnight.
- Results showed that the supplement improved protein balance but did not affect muscle protein synthesis rates despite increased amino acids in the blood, suggesting that taking protein before bed could help prevent overnight muscle loss.
Background: Ageing is associated with decrease in tissue glutathione that can be reduced by food fortification with the amino acid cysteine. However, cysteine is not stable in solution and generates bad taste. Cystathionine, the direct precursor of cysteine, could be a valuable alternative.

Rats, age 28days were supplemented for 4weeks with high Ca (1.2%), adequate Ca (0.

Recent data suggest that a diet, Clinutren Protect (CP), containing whey proteins, glutamine, and transforming growth factor-beta (TGFbeta)-rich casein limits intestinal mucositis and improves recovery after a single methotrexate (MTX) challenge in rats. Chemotherapy consists of alternating periods of treatment and rest.
