PeptiStrong is a patented hydrolysate obtained from fava bean protein (Vicia faba) through aqueous enzymatic hydrolysis. This process releases small peptides, more easily assimilated than whole proteins, selected for their demonstrated biological activity on muscle synthesis and protection. Each 4-capsule dose provides 2,400 mg of protein concentrate, including 1,400 mg of specific bioactive peptides, identified using artificial-intelligence-driven analysis technology.

PeptiStrong’s peptides act directly on the cellular mechanisms involved in building and preserving muscle tissue. Clinical studies have shown that, at 2.4 g per day, PeptiStrong activates protein-synthesis pathways and positively modulates the anabolism/catabolism balance — a targeted action that sets it apart from classic proteins, which supply amino acids without specifically influencing the cellular mechanisms of muscle growth.

Classic proteins (whey, casein, plant proteins) provide a pool of amino acids to cover general nutritional needs. PeptiStrong’s bioactive peptides go further: they were identified for their ability to interact directly with the cellular signalling pathways involved in muscle synthesis. At an equal protein amount, PeptiStrong has shown superior efficacy on certain muscle-growth markers compared with milk protein in research — a difference explained by the specificity of the selected peptide fragments, which act as biological signals rather than simple nutrients. The aqueous enzymatic hydrolysis keeps these functional peptides intact.

Identifying PeptiStrong’s bioactive peptides relies on artificial-intelligence analysis technology developed by Nuritas. Among the thousands of peptide fragments generated during fava bean protein hydrolysis, only those showing demonstrated biological activity on muscle synthesis and protection are retained. This process yields a peptide concentrate whose effectiveness is validated by human clinical studies. The extraction method is exclusively aqueous and enzymatic, with no chemical solvent. The final product is guaranteed free from excipients, GMOs and nanoparticles, and is not tested on animals. PeptiStrong is a registered trademark of Nuritas.

Take 4 capsules a day (2,400 mg of protein concentrate) with a large glass of water. It can be taken before or after training, or with a meal — this dose matches the one used in the reference clinical studies. PeptiStrong can be used continuously or during periods of increased need (intensive training, post-injury recovery, prevention of age-related muscle loss). The 120-capsule bottle covers a month’s course at the standard dose of 4 capsules a day.

PeptiStrong suits athletes wanting to optimise muscle mass gain and recovery, older adults wanting to help prevent sarcopenia (age-related muscle loss), and people on a vegan diet looking for a high-performance, 100% plant-based protein supplement. Its high digestibility and absence of major allergens (gluten, lactose, soy) make it a suitable option for people with digestive sensitivities. Athletes subject to anti-doping testing can verify the product’s compliance with Dynveo, whose production is ISO certified.

Not recommended for people with favism (G6PD deficiency), due to the fava bean origin of this product — consult your doctor if in doubt. Also not recommended for pregnant or breastfeeding women. Do not exceed the recommended daily dose of 4 capsules. Food supplements should not replace a varied, balanced diet and a healthy lifestyle. Vegan product, free from known allergens (except fava bean), gluten-free, lactose-free, soy-free, GMO-free, no nanoparticles. Vegetable pullulan capsules.

Is PeptiStrong suitable for all ages?

Yes — PeptiStrong suits adult athletes as well as older adults wanting to limit muscle mass loss. Thanks to its digestibility and absence of major allergens, it can be taken from adulthood regardless of initial fitness level. People with favism should, however, avoid it.

What is the difference between PeptiStrong and whey?

Whey provides amino acids to cover daily protein needs. PeptiStrong acts on specific cellular mechanisms involved in building and protecting muscle tissue. Its plant (fava bean) origin makes it compatible with a vegan diet, unlike dairy-derived whey.

How should I use PeptiStrong day to day?

The recommended intake is 4 capsules a day (2,400 mg) with a large glass of water — this dose has been validated in clinical studies. It can be taken all at once or split in two, before or after training, or with a meal. The 120-capsule bottle covers a month’s course.

Does PeptiStrong carry any allergy risk?

PeptiStrong is gluten-free, lactose-free, soy-free and GMO-free. The one point of caution concerns people with favism (G6PD deficiency), due to its fava bean origin. Outside this situation, no notable side effect has been reported in clinical studies, and digestive tolerance is excellent.
