Our pure amino acids
for your food supplements
Provided in purified form, L-Cystine is incorporated into food supplements to support the growth and vitality of hair and nails.
In supplementation, L-Tyrosine (as a precursor of dopamine) is beneficial on the stimulation of cognitive functions (memory and fight against stress). Many clinical studies have demonstrated its effectiveness.
L-Tyrosine is also the precursor of melanin, responsible for skin pigmentation.
For hair and nails
• L-Cystine (850 µm),
• L-Cystine Screened (250 µm),
• L-Cystine Micronized (180 µm)
For concentration and stress management
• L-Tyrosine Low Phenylalanine
clinically proven ingredients
Kera-Diet® improves the condition of hair and nails: shine, volume, density, growth and vitality. It also stimulates the production of endogenous glutathione in keratinocytes.
- Traced origin, from a sustainable protein source.
- Stable and unique profile of 17 amino acids, 86.5% in free form.
- Instantaneous assimilation thanks to a very low molecular weight (100% < 800 Daltons).
- Proven effectiveness: in vitro studies and a randomised, double-blind, placebo-controlled clinical study.
Given the functional properties of Traced L-Cystine, this amino acid combined with L-Glutathione as an oral dietary supplement could accelerate the production of light melanin and therefore produce a safe skin lightening effect.
To prove this, a 90-day double-blind clinical study was conducted and demonstrated that taking 750 mg of Cysti-White® daily, consisting of Traced L-Cystine combined with Glutathione, and supplemented with antioxidants, amino acids, trace elements and vitamins, significantly improves skin lightening of the face and arms and reduces the size of dark spots on the face.
