Nutrition technology company L-Nutra has launched the Prolon L bar – a plant-based protein bar formulated to support muscle health and healthy ageing as well as fuelling workouts.

While most protein products focus on quantity, highlighting the amount of protein in grams and the amount of calories, L-Nutra pointed to emerging longevity science suggesting that too much of the wrong kind of protein can accelerate ageing by overstimulating key growth pathways like IGF-1 and mTOR. Meanwhile, too little protein may fail to adequately support muscle maintenance and overall strength.

The L-Protein Bar is formulated to provide the ‘perfect balance’ of amino acids from plant-based sources to deliver the right nutrients designed to enhance longevity, created by scientists at the USC Longevity Institute.

It includes a diverse blend of plant proteins from black beans, chickpeas and peas, and is fortified with l-methionine – an essential amino acid that is commonly low or missing in vegan diets and other vegan protein supplements.

The targeted formulation aims to maintain a balanced growth factor response while delivering complete protein support for muscle and tissue health.

Each bar contains 14g of protein, 170 kcal, and is made without added sugars, sugar alcohols or artificial sweeteners. It is naturally sweetened with whole dates for a rich flavour and a more balanced glycemic response.

In addition to being plant-based, the bar is gluten-free, soya-free, non-GMO and made with heart-healthy fats from extra virgin olive oil and cocoa butter.

It is initially available in a rich Chocolate Coated flavour, featuring a 100% dark chocolate layer, with additional flavours planned as part of L-Nutra’s expanding Longevity Nutrition platform – a product suite designed to help consumers integrate clinically backed nutrition into daily life.
