THE FORMULA
Every ingredient earns its place.
With biotin for hair and skin, niacin for skin.²
Stronger, fuller, glossier hair
Key ingredients:KeraDiet® KeratinBiotin
Stronger, harder nails that grow back better
Key ingredients:KeraDiet® KeratinBiotin
The gut-skin axis, working
Key ingredients:SynbÆctive® Bacterial CulturesOrafti® InulinDRcaps®
Backed by two independent clinical studies. SynbÆctive® ProBeautyShield: +30% skin hydration, −20% transepidermal water loss (RDBPC, 80 subjects, 56 days). KeraDiet® keratin peptides: +17% skin hydration, +43% skin gloss, −12% wrinkle depth, +9.7% skin firmness (RDBPC, 99 women, 90 days). Niacin and biotin contribute to the maintenance of normal skin.*
KeraDiet® supplies the exact 17 amino acids your body uses to build keratin — in peptide form (<800 Da) for near-complete absorption. Clinical research on KeraDiet®: +61% hair gloss, −33% hair loss (RDBPC, 99 women, 90 days). Biotin contributes to the maintenance of normal hair.*
Nails are largely keratin. KeraDiet® delivers it in the form your body actually absorbs. Documented in KeraDiet® clinical research: improvements in nail integrity alongside the hair and skin endpoints (RDBPC trials at 500–1000 mg/day, the dose used in KeraBiotic).
20 billion bacterial cultures from the SynbÆctive® complex — including the ProBeautyShield strains studied for skin — plus Orafti® HSI prebiotic inulin to feed them. Delivered in DRcaps® acid-resistant capsules: 52-minute delayed release vs. 7 minutes for standard capsules (gamma scintigraphy, Bio-Images Research). The cultures arrive where they work.

THE SCIENCE
Radiant skin starts in the gut.
The building blocks of your skin aren't applied — they're produced.
-
Bacterial cultures
populate the gut microbiome — where the body absorbs nutrients
-
Amino acids
absorbed in the gut, carried to the skin through the bloodstream
-
Keratin
the same protein your hair, skin, and nails are made of — built from these exact amino acids
GUT MICROBIOME
BLOODSTREAM
HEALTHY SKIN
Gut microbiome → amino acids → keratin.

¹ Randomised, double-blind, placebo-controlled study on the active ingredient Kera-Diet® (hydrolyzed keratin): n = 99 women (aged 35–65), randomised to placebo, 500 mg or 1000 mg daily for 90 days. Day-90 results, 500 mg arm: hair gloss +42.2%, skin gloss +35.8%, nail gloss +62.2%, wrinkle depth −9.4%; 90% of participants with a visibly improved nail appearance. Hydrolysis breaks keratin into peptides and free amino acids — easier to absorb than intact protein. Results refer to the active ingredient Kera-Diet®, not to the finished product KeraBiotic.

³ SynbÆctive® Premix10 (SynBalance srl): 20 billion CFU from 10 documented bacterial strains per daily dose (2 capsules), plus 200 mg Orafti® HSI inulin as a prebiotic. Contains the gut-skin-axis complex ProBeautyShield (L. plantarum PBS067, L. rhamnosus LRH020, L. reuteri PBS072), a NutraIngredients Award winner (2022 and 2024): in a placebo-controlled study in people with sensitive, atopy-prone skin (n = 80, 56 days) the complex improved skin hydration by over 30% and reduced transepidermal water loss by 20% (Michelotti et al. 2021). Results refer to the active ingredient, not to the finished product KeraBiotic. Gastro-resistant DRcaps® capsules (Lonza) with delayed release.
