120 Caps

Efectiv Nutrition Peptide 120 Capsules With 2400mg PeptiStrong and Vitamin D3

Efectiv Nutrition Peptide is a two ingredient capsule formula. Each four capsule serving delivers 2400mg PeptiStrong and 75µg vitamin D3. The 120 capsule bottle provides 30 servings.

PeptiStrong is a peptide network discovered by Nuritas using AI and produced from hydrolysed fava bean protein. It is the dose used in the published clinical work, where two studies reported improved power output by up to 130%, increased performance by up to 54% and a 47% increase in strength recovery, alongside reduced muscle soreness and suppressed plasma myostatin. A third study reported muscle protein synthesis rates four times greater than the same amount of whey protein during remobilisation. The references are listed in full on this page.

The vitamin D3 is vegan, sourced from lichen rather than lanolin, at 75µg or 1500% of the nutrient reference value. Vitamin D contributes to the maintenance of normal muscle function, contributes to the maintenance of normal bones, and contributes to the normal function of the immune system.

Peptide suits hybrid athletes, functional fitness and HYROX style training, and anyone adding PeptiStrong to an existing stack in capsule form rather than powder. It is vegan friendly, contains no known allergens, and results still depend on consistent training and adequate protein intake.

Frequently Asked Questions

What is PeptiStrong and how much is in Efectiv Peptide?

PeptiStrong is a bioactive peptide ingredient derived from hydrolysed fava bean protein, identified by Nuritas through AI-driven screening of thousands of peptide sequences. The peptides are absorbed through the PepT1 intestinal transporter, which is a different pathway to standard free-form amino acids. Efectiv Peptide provides 2400mg per 4-capsule serving, which is the dose used in the published clinical research.

Why is there vitamin D3 in a muscle builder?

Vitamin D contributes to the maintenance of normal muscle function, contributes to the maintenance of normal bones, and contributes to the normal function of the immune system. Efectiv Peptide provides 75µg (3000IU) per serving, which is 1500% of the nutrient reference value. The D3 is vegan, sourced from lichen rather than lanolin, so the whole formula is plant-based.

Can I take Efectiv Peptide alongside whey protein and creatine?

Yes. Efectiv Peptide is designed to sit on top of your protein and creatine routine rather than replace either. Whey provides amino acids, creatine supports training output, and Peptide adds PeptiStrong and vitamin D3 as a separate ingredient stack. There is no interaction concern between these products, and adequate daily protein intake is still needed.
