Tel Aviv, Israel—A new supplement for preadolescent boys has been shown in a clinical trial to support healthy growth and development, according to a press release from Nutritional Growth Solutions, Ltd., makers of Grow Daily Boys 10+ protein drink powder.

The 12-month, randomized, double-blind, placebo-controlled study was published inActa Paediatrica.It included two stages. Stage 1, which took place for the first six months, was a double-blinded intervention with nutritional formula or placebo. Stage 2, which took place from months 6-12, was an open-label extension wherein all 160 participants took the nutritional formula.

The supplement contains about 25% of the recommended dietary reference intake for calories, 18g of whey protein, and added vitamins and minerals. The placebo powder was relatively low in energy and protein, and without added vitamins and minerals.

The participants who consumed Grow Daily Boys 10+ gained significantly more in weight, BMI, fat-free mass, and muscle mass than the placebo group did, in a dose-dependent manner.

“Intervention with a multi-nutrient, protein-rich formula was effective at increasing weight and body mass index (BMI), mostly from fat-free-mass and muscle mass, in short and lean prepubertal male adolescents,” explained lead researcher Michal Yackobovitch-Gavan, Ph.D., Dietitian and Researcher for Schneider Children’s Medical Center. “It also prevented the expected slowdown in height growth in children older than 11.4 years. This is a key trial that evaluated the importance of nutrition for pre-adolescents and is certain to inspire more research.” Plus, children who consumed at least half of the recommended doses of the nutritional supplement formula improved their intake of macro- and micronutrients necessary for growth.

“Grow Daily Boys 10+ ticks all the right boxes when it comes to growth and development of pre-adolescents,” notes Liron Fendell, CEO and Managing Director of NGS. “It was developed and tested by pediatricians, and clinically shown to help pre-teens and teens increase muscle mass. School lunch and fast food are part of our kids’ menu, so it is important to balance their diet and fill the gap with vital nutrients.
