What are Fortigel bioactive collagen peptides?

Fortigel is a specific formulation of collagen peptides optimized for joint cartilage support. Clinical studies suggest Fortigel may stimulate cartilage cell metabolism and increase collagen production in joint tissue.

What is the difference between Type I and Type III collagen?

Type I collagen is the most abundant in the body and primarily supports skin, bones, and tendons. Type III is found alongside Type I and supports skin elasticity and cardiovascular tissue. Both decline with age.

Why combine collagen with nicotinamide riboside?

NAD+ is involved in collagen synthesis pathways. The theory is that boosting NAD+ while providing collagen peptides may enhance the body's ability to produce and maintain collagen, though direct clinical evidence for this combination is still emerging.

Is multi-type collagen better than single-type?

The theory is appealing — different collagen types support different tissues. However, clinical research has not yet demonstrated that multi-type collagen supplements produce meaningfully better outcomes than single-type (typically Type I/III) products.

How much collagen should I take daily for longevity benefits?

Most clinical studies showing benefits use 10-15g of collagen peptides daily. Sports Research provides 11g per serving, which falls within the evidence-based range for skin and joint support.
