Nail Growth Isn’t Just Genetic—It’s Nutritional
Whether you’re trying to grow out a broken nail or you’re simply after a stronger, smoother manicure base, you’ve probably heard one word over and over again: biotin. It’s the beauty industry’s go-to nutrient for everything from brittle nails to thinning hair.
But here’s the truth: biotin is just the beginning. Today’s nail health market includes a range of powerful, science-supported ingredients and one in particular is making headlines for its cellular-level rejuvenation: Yüth™ (spermidine).
Let’s take a closer look at the key players in the nail health game and why Yüth™ may be the next-gen answer you’ve been searching for.
Biotin: The Tried-and-True Favorite
Biotin (vitamin B7) is a water-soluble vitamin that helps your body metabolize amino acids, crucial for keratin production, which makes up your nails. It’s been linked to reduced nail brittleness and slightly faster growth. However, biotin supplements can take months to show results. Further, for people without a biotin deficiency, the added benefit may be minimal. While it’s a solid foundational nutrient, many users plateau on biotin alone.
Yüth™ (Spermidine): Cellular Beauty from the Inside Out
Enter spermidine, a polyamine that occurs naturally in the body but declines as we age. Yüth™, a nature-identical, GRAS-certified form of spermidine, is emerging as one of the most scientifically promising ingredients for nail health.
In a human clinical trial, just 3mg/day of Yüth™ led to a 400% increase in nail growth compared to placebo. Participants not only grew longer nails faster but also experienced less chipping, splitting, breakage, and ridging—all while improving nail bed color and overall appearance. The secret lies in spermidine’s ability to stimulate autophagy—your body’s natural cellular clean-up process—and promote keratin production. This addresses nail health at its root: the nail matrix.
Unlike biotin, Yüth™ doesn’t just support nail formation; it renews the foundation of nail growth. Its dual impact on both cellular turnover and protein synthesis makes it a standout for both beauty and longevity.
Collagen: Structural Support That’s More Than Skin-Deep
Collagen is another top contender, particularly type I and type III collagen peptides, which help reinforce the connective tissues under the nail bed. While not directly linked to nail length, collagen can improve nail resilience and reduce breakage. This can be key for anyone trying to grow nails longer without setbacks. It’s especially effective when paired with hyaluronic acid or vitamin C, which aid in collagen synthesis and hydration.
Zinc: The Often-Overlooked Mineral for Growth and Repair
Zinc plays a crucial role in protein and cell production, two processes essential for nail growth. Deficiencies can lead to white spots on nails, ridging, and slow regrowth. Supplementing with zinc, especially in bioavailable forms like zinc picolinate or bisglycinate, can help normalize the nail growth cycle and repair weak or damaged nails. While it’s often overshadowed by flashier beauty ingredients, zinc remains a foundational nutrient for strong, even nail growth.
Which Nail Growth Ingredient Is Best?
It depends on your goals but if you’re looking for a next-level upgrade, Yüth™ stands out for its dual-action benefits. It doesn’t just support growth; it rejuvenates the entire nail environment, from root to tip.
Stronger Nails Start From Within
Beautiful, healthy nails aren’t just the result of polish and upkeep; they’re the product of deep internal wellness. Whether you’re dealing with chronic brittleness or just want to optimize your growth potential, focusing on the right ingredients can transform your nails in a matter of weeks.
