Nail Growth Isn’t Just Genetic—It’s Nutritional
Whether you’re trying to grow out a broken nail or simply want 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).
Biotin: The Tried-and-True Favorite
1. What it is: Vitamin B7, a water-soluble vitamin that supports amino acid metabolism and keratin production.
2. Benefits: Linked to reduced brittleness and slightly faster nail growth.
3. Limitations:
- Results can take months to appear.
- Added benefit may be minimal for those without a deficiency.
4. Bottom line: A solid foundational nutrient, but many users plateau on biotin alone.
Yüth™ (Spermidine): Cellular Beauty from the Inside Out
1. What it is: A polyamine naturally present in the body but declining with age. Yüth™ is a nature-identical, GRAS-certified form.
2. Clinical trial results:
- Just 3 mg/day led to a 400% increase in nail growth compared to placebo.
-
Participants also experienced:
Less chipping, splitting, and breakage
Smoother ridges and improved color
Overall stronger nail appearance
3. How it works:
- Stimulates autophagy, clearing out damaged cells for renewal.
- Boosts keratin production, essential for nails, hair, and skin.
4. Why it matters: Unlike biotin, Yüth™ rejuvenates the nail matrix at a cellular level, supporting both renewal and structure.
Collagen: Structural Support That’s More Than Skin-Deep
- Role: Provides amino acids that strengthen connective tissues under the nail bed.
- Impact: Improves nail resilience and reduces breakage.
- Best use: Especially effective when combined with vitamin C or hyaluronic acid for enhanced collagen synthesis and hydration.
Zinc: The Often-Overlooked Mineral for Growth and Repair
- Function: Essential for protein synthesis and cell production—both key to nail growth.
- Deficiency signs: White spots, ridges, and slow regrowth.
- Supplementation: Bioavailable forms like zinc picolinate or bisglycinate can help restore normal growth cycles and repair weak nails.
Which Nail Growth Ingredient Is Best?
- Biotin: Reliable but limited.
- Collagen & Zinc: Support structure and resilience.
- Yüth™: Stands out for its dual-action impact on autophagy and keratin production, making it a next-generation solution for nail health.
Stronger Nails Start From Within
Beautiful, healthy nails aren’t just the result of polish and upkeep—they are the outcome of deep internal wellness. By focusing on the right nutrients, you can transform nail strength, resilience, and growth in just weeks.
Want nails that grow faster and stronger? Start from within with smart science and proven support.
