Multi Enzyme Complex Supplementation Relieves Symptoms of Dyspepsia

Functional dyspepsia (FD) is characterised by a collection of symptoms that may include bloating, nausea, heartburn, burping and post-prandial fullness. 1 A multienzyme complex was evaluated to investigate its effects in adults with functional dyspepsia. 1

Methods: 40 adults diagnosed with FD were enlisted in a randomized, double-blind, placebo-controlled, parallel-group trial. Subjects were administered either a multi-enzyme complex three times daily or a placebo over a 60 day period.

Results: Supplementation with a multienzyme complex was significantly associated with reductions in all indicators of efficacy compared to placebo. Findings suggest multi enzyme supplementation was shown to be both a safe and effective in managing symptoms associated with functional dyspepsia. 1

New study using GABA and whey protein to build body mass in males

Using GABA and whey protein to build body mass in males

Supplementing with gamma-aminobutyric acid (GABA) and whey protein after resistance training helps males build fat-free body mass, according to the results of a new study.

Using 125mg of Pharma GABA (equivalent to 100mg of GABA), and 10g whey protein for 12 weeks, GABA was found to increase both growth hormone (GH) and protein synthesis, thus contributing to exercise-induced muscle hypertrophy [1].

GABA’s uses within the human body are varied, including it’s role as an inhibitory neurotransmitter, anxiolytic and relaxant via increasing parasympathetic nervous system activities [2-5] . However from a physiologic perspective, GABA controls the pituitary gland’s secretion of GH, thus having a key role in muscle growth [6, 7]. Furthermore, GH facilitates increased amino acid transport and cellular amino acid uptake [8].

In the single-blind, randomised and placebo-controlled study, 26 males were randomised into two groups, either whey protein (WP) only or WP + GABA. Resistance exercise was undertaken twice per week, with supplementation administered 15 minutes prior to training or prior to sleep on the exercise-free days [1].

Results at weeks 4 and 8 showed substantially higher resting plasma GH concentrations in the WP + GABA group compared to baseline. This was responsible in part for the significantly enhanced whole body fat-free mass in participants in the WP + GABA group versus WP alone [1].
