Inner Youth Collagen Powder Mango Passion - 450g
Transform and support your nails from weak and brittle to stronger, smoother, and visibly healthier with our advanced collagen blend, specially formulated to support nail strength from within. Now in a refreshing Mango Passionfruit flavour.
Results in 4 weeks:
- Stronger, harder nails
- Less peeling and splitting
- Smoother, healthier-looking nail growth
- Longer nails with less breakage
A highly absorbable collagen peptide blend designed to visibly smooth fine lines + wrinkles, support firm, plump skin, deeply nourish your hair, nails, joints, and gut in as little as 4 weeks.
As we age, our natural collagen production declines, leading to signs of ageing, brittle hair and nails, joint stiffness, and digestive issues. Inner Youth is formulated to combat this decline by delivering clinically-backed hydrolyzed peptides that your body can actually absorb and use.
Proudly made in New Zealand.
Free From: Fillers, Binders, Additives, Added Sugar, Dairy + Gluten
Inside every scoop of Inner Youth, over 10,000 mg of premium grass-fed, pasture-raised bovine collagen peptides (Types I, II & III) go to work restoring the collagen your body stops producing in your mid 20's. These bioactive peptides are clinically shown to absorb quickly, helping to rebuild collagen from within so skin regains elasticity and deep hydration, hair and nails grow stronger, joints move with ease, and gut lining and digestion improve and stay balanced.
To supercharge this collagen base, we've added Hyaluronic Acid (55 mg) to lock in moisture, plump and smooth the skin, and cushion joints for comfort and flexibility. Vitamin C (55 mg) drives natural collagen synthesis and shields against everyday stressors, sun, pollution, and free radicals for a firmer, brighter, more youthful look. Finally, Biotin (10 mg) the renowned “beauty vitamin” strengthens hair and nails at the root, nourishes the skin, and supports natural energy metabolism for a healthy glow from the inside out.
Working in synergy, these four powerhouse ingredients create a formula your body can actually use. The result? Firmer, smoother skin, stronger hair and nails, improved joint comfort, and balanced digestion often visible in as little as four weeks.
Most people notice visible improvements in as little as 4-6 weeks, starting with stronger nail growth, less peeling, and fewer breaks at the tips. With continued daily use, nails often grow smoother, thicker, and more resilient as collagen supports the structure of the nail as it forms.
Just 1-2 scoops a day helps support stronger nail growth and maintain long-term results.
What you can expect in the first 28-42 days:
