Collagen Showdown: Surprising NAD Boost Tested for Skin & Joint Benefits In the ever-expanding world of collagen supplements, the latest contenders are not just about the protein-they're about the science behind it. From joint-focused formulas to gut-supporting powders, the market is alive with options. But one ingredient has emerged as the unexpected hero: NAD, the coenzyme linked to cellular energy and longevity. Here's how it stacks up against the classics. Take Youtheory Joint Complex with UC-II: a collagen type 2 blend for joints, paired with Boswellia, ginger, and turmeric, promising support without dairy, soy, or gluten. Then there's Vitalitown's 11-in-1 formula, a powerhouse of glucosamine, chondroitin, MSM, and more, delivering flexibility and comfort with 1500 mg of glucosamine sulfate-ideal for those avoiding shellfish. Meanwhile, Multi Collagen Peptides Powders take a different route, combining hydrolyzed proteins from multiple types (I, II, III, V, X) with probiotics, HA, and biotin to tackle skin, hair, nails, and gut health in one go. But the real twist? Hydrolyzed Collagen Peptides with NAD, a formulation that marries traditional collagen benefits with this emerging nutrient. Unlike others, it emphasizes cellular vitality, hinting at deeper rejuvenation. Whether you're after joint relief, skin elasticity, or a holistic approach, the choice is clear: while collagen remains the foundation, NAD is the underdog making waves.
