Whey protein powder is widely used for muscle growth and recovery, but emerging research shows it also interacts closely with the gut microbiome. Specific whey proteins and peptides can influence bacterial growth, microbial metabolism, and the production of short-chain fatty acids (SCFAs), which play a key role in colon health. This article explores what whey protein is, what happens when you take it daily, and how its bioactive components affect gut health — using current scientific understanding while keeping things practical and easy to follow.

New research shows that glycine, especially when combined with leucine, can significantly improve fatty liver disease, inflammation, and metabolic health. Each serve of 40up provides 4.5 g of glycine and 3 g of leucine, matching the therapeutic doses used in these studies. For men and women over 40, this means 40up supports not only muscle strength and recovery but also whole-body metabolic health — including the liver.

A large systematic review of 61 controlled trials shows that creatine significantly increases lean muscle when combined with resistance training—without increasing body fat. The research also reveals that experienced lifters gain up to 50% more lean mass than beginners, even in shorter timeframes, due to better insulin sensitivity and muscle creatine uptake. For men and women over 40, these findings are especially important, as ageing muscle becomes less responsive to training alone. With an evidence-based 3 grams of creatine per serve, CollagenX 40up aligns directly with the science, supporting lean muscle, strength, and training performance after 40.

Most people think protein is only about building muscle. But after 40, the real challenge is maintaining the connective tissues that keep your body strong, mobile and resilient — your tendons, ligaments, cartilage and joints. In this article, we explore the fascinating science of how the body constantly rebuilds itself, why exercise and nutrition work together, and why collagen plays a unique structural role that traditional proteins can’t replace. Discover why high-quality hydrolysed collagen is becoming an important part of healthy ageing — and how choosing a clean, skin-sourced collagen like CollagenX may help support strength, recovery and long-term joint...
