Protein supplements are extensively used for muscle building, weight loss, recovery from exercise, improving endurance & cardio-performance. Major challenge with protein supplement is undigested protein and impaired gut health which results in nausea, dehydration, diarrhea, constipation, indigestion, stomach pain, and decreased appetite.Several studies have linked plant protein with reduced metabolic syndrome incidence.Probiotics can improve gut health as well. The objective of the study is to assess the efficacy and safety of protein supplement in promoting health and wellbeing in healthy adults. The present trial is a double blind, multi-center, randomized, placebo controlled, clinical trial involving 60 healthy individuals. The treatment duration was of 90 days. The subjects were randomized to receive either protein supplement treatment or placebo control. Protein supplement significantly improved quality-of-life score by 85.76%, VO 2 max by 42.92%, distance covered in 6 minutes, 100% individuals with at least 25% reduction in low energy events as compared to the control group. Protein supplement treatment reduced body weight (1.94 kg), waist circumference (2.46 cm), body mass index, waist circumference, hip circumference and body fat. Remarkable and significant improvement in digestive and sleep quality score, percent skeletal muscle was observed among protein supplement treated group. There were no clinically significant changes in hematological, biochemical and vital parameters; indicating safety of protein supplement. Present study concluded that protein supplement is safe and efficacious in weight management, improving high energy events, aerobic capacity, quality of life, digestive behavior score and sleep quality. This study ensures consumers about safety and effectiveness of protein supplement.

Male infertility is solely responsible for 20–30% of infertility cases. Oxidative damage of sperm DNA is positively linked with oligoasthenoteratozoospermia (OAT), and male infertility. The antioxidants are being explored worldwide to combat OAT, sperm DNA fragmentation and reactive oxygen species. The objective of the study was to assess the effectiveness of an antioxidant blend in improving sperm count, semen parameters and reducing DNA fragmentation index (DFI) in sub-fertile males. A prospective, double-blind, randomized, placebo-controlled trial was conducted in 300 sub-fertile males (25–45 years) from ten study sites in India. Subjects were randomized in either the antioxidant blend treatment group or placebo group. We assessed changes in sperm count, motility, normal morphology, semen volume, and percent DFI before and after treatment (90 days). To further stratify data on different criteria post hoc analysis was performed. Statistical analysis was performed using SPSS 10.0 software. There were improvements in sperm count, semen volume, sperm motility, and sperm normal morphology in the treatment group. There was improvement in sperm count in severe oligospermia subjects (sperm count < 5 million/mL, 5–10 million/mL, 10.1–15 million/mL), and high-extremely higher baseline DFI (20–30%, 31–40% and above 40%), as per post hoc analysis. There was no premature discontinuation and adverse events were reported during the study, indicating safety and well-tolerability of treatment. Study results confirmed the well-researched fact of antioxidants being effective to reduce oxidative stress and thus improve sperm DNA integrity and also improved semen parameters in males aged 40 and above.
