Gundry MD launches creatine-peptide supplement for strength

The ingredients help recharge adenosine triphosphate (ATP) — the cell’s energy currency — to support a stronger body, faster recovery, and a sharper mind.

In a single daily scoop mixed with water, creatine fuels the muscles and brain while PeptiStrong signals muscles to rebuild for faster recovery and lasting gains. Vitamins K2 and D3 support the bones and heart that keep the body active.

The vegan powder comes in a sugar-free cherry limeade flavor and is sold directly to consumers through the brand’s website. Dr. Steven Gundry, former cardiothoracic surgeon and founder of the brand, states, “Everyone’s finally discovering what athletes have known for decades: creatine works. But plain creatine only takes you so far. So, I made the version I’d actually take: high-quality creatine, made even better with a plant peptide that ‘tells’ your muscles to rebuild.”

The company explains that the human body constantly breaks down dietary proteins into amino acids, which cells then utilize to repair muscle, bone, brain, and cardiac tissue. This cellular restoration process relies heavily on specific chemical signals to initiate, known medically as “anabolism.”

Anabolic resistance often develops with age, leading cells to become less responsive to these critical repair cues. Many people “feel weaker each year” as a result. In Gundry MD’s internal, non-scientific 12-week user group, 30 participants aged 36 to 79 took the formula once daily and self-reported broad improvements in physical stamina, mobility, strength, and mental clarity.

The peptide is a patented, plant-based network of bioactive signaling peptides derived from the enzymatic hydrolysis of fava beans and supplied by Nuritas. The ingredient was identified using Nuritas’ Magnifier platform and functions as a targeted cellular signaling network, adding a novel component to the supplement’s design.

According to company literature and published research, its proposed mechanisms aim to upregulate muscle synthesis by triggering the mTOR and Phospho-S6 cellular pathways and downregulate muscle breakdown by suppressing markers such as atrogin-1, MuRF1, and myostatin. Each serving of the product contains 2.4 g of PeptiStrong, which Nuritas’ clinical data indicates improves strength recovery and reduces exercise-induced muscle fatigue.

One of the published PeptiStrong trials, conducted by Maastricht University in the Netherlands with Nuritas, found no differences between the fava bean peptide network and milk protein in muscle size and strength loss during immobilization, or in their recovery afterward. Nuritas has highlighted the trial’s finding of a higher muscle protein synthesis rate during recovery.

PeptiStrong holds self-affirmed Generally Recognized as Safe status and is approved by Health Canada. It also features in HUM Nutrition’s August 2026 launch of Stack & Sculpt, a peptide-powered creatine formulated to tone, support recovery, and help maintain muscle.
