Aloysia citriodora (L.) leaves are used as food and food supplements. A proprietary standardized Aloysia citriodora leaf extract was investigated for its anti-inflammatory effects by inhibition of cyclooxygenase (COX). Two isozymes were tested, ovine COX-1 isozyme and human recombinant COX-2 isozyme. Aloysia citriodora leaf extract showed significant dose-dependent effects to inhibit cyclooxygenases, demonstrating anti-inflammatory activity. Results may indicate beneficial effects for sports nutrition to prevent muscle soreness, muscle damage, and to improve recovery after physical exercise.

Folate required to achieve desirable red blood cell (RBC) folate concentrations within 4-8 weeks pre-pregnancy is not known. We studied the effect of supplementation with 400 or 800 µg/day folate in achieving RBC-folate ≥906 nmol/L.

Systemic enzyme therapy may improve symptoms of exhaustive eccentric exercise due to anti-inflammatory properties. In a randomised, placebo-controlled, two-stage clinical trial, systemic enzyme therapy (Wobenzym) was administered for 72 hours before and 72 hours following a day on which subjects performed an exhaustive eccentric exercise (isokinetic loading of the quadriceps). Efficacy criteria (maximal strength and pain) and time points were selected to account for the multidimensional nature of exercise-induced muscle damage symptoms. Subjects were randomised in a crossover (stage I, n=28) and parallel group design (stage II, n=44).

Age-related muscle loss is characterised by a progressing decrease in muscle mass, strength and function. Besides resistance training and physical activity, appropriate nutrition that is rich in protein, especially branched-chain amino acids, is very important to support training effects and positively influence the protein synthesis to degradation ratio. The purpose of this study was to evaluate the effect of a 12-week leucine-rich amino acid supplementation in combination with moderate training.

A commercial Mangifera indica fruit powder (Careless) showed beneficial acute effects on microcirculation in a randomized, double-blind, crossover pilot study. Here, long-term effects on microcirculation and glucose metabolism were investigated in a double-blind, randomized, placebo-controlled, 3-arm parallel-design study in healthy individuals.

Nutrition plays an important role in prevention and management of cardiovascular diseases (CVD) in early stages. Recent research demonstrated beneficial effects of various nutritional ingredients on vascular health. The aim of the current study was to evaluate the effects of an L-arginine-based multi ingredient product (AbMIP) on vascular function.
