Collagen is a structural protein naturally present in the skin and connective tissue. Its structure is characterised in particular by a high proportion of glycine, proline and hydroxyproline, amino acids typical of collagen. 

Our formula uses hydrolysed marine collagen peptides Naticol®, derived from type I fish collagen. Their enzymatic hydrolysis produces low-molecular-weight peptides, designed to make them easier to use in nutritional formulations. 

Hydrolysed collagen peptides are the subject of extensive clinical research. A meta-analysis published in 2023 pooled 26 randomised trials and 1,721 participants studying various skin parameters. The results suggest a potential benefit of hydrolysed collagen supplementation on certain skin parameters.

Naticol® also has specific data from consumer panels. In a panel of 63 women, after 28 days of daily use, 87% of participants reported an overall improvement in the appearance of their skin, 89% felt their skin was more hydrated, 87% more supple and 75% firmer. These results reflect subjective assessments reported by the participants. 

Creatine is a compound naturally present in the body. In muscle, it is part of the creatine–phosphocreatine system, which is involved in the rapid regeneration of ATP, the main source of energy directly usable by the muscle cell.

Of the various forms available, creatine monohydrate is the most studied in the scientific literature and is the reference form in the majority of clinical trials.

From 3 g of creatine per day, creatine increases physical performance in successive bursts of short-term, high-intensity exercise. The beneficial effect is obtained with a daily intake of 3 g of creatine.

In adults aged 55 and over, daily creatine consumption can also enhance the effect of resistance training on muscle strength. The beneficial effect is obtained with a daily intake of 3 g of creatine combined with regular resistance training that allows the load to be progressively increased.*

Recent scientific work continues to document the benefits of creatine supplementation, particularly when combined with resistance training. In both adults and older adults, the available data confirm that the best-established benefits relate above all to muscle strength and performance during repeated intense efforts.

* The claim relating to adults aged 55 and over applies when creatine is combined with resistance training performed regularly, at least three times a week for several weeks, at an intensity that allows the load to be progressively increased.

Natural astaxanthin is a carotenoid extracted from the microalga Haematococcus pluvialis. It is the subject of extensive research for its role in mechanisms related to oxidative stress and the protection of cell membranes.

Our astaxanthin is produced in Belgium by Axabio from microalgae grown in closed photobioreactors, then extracted using supercritical CO₂, a process free from organic solvents. The raw material is tested for its astaxanthin content, isomers, contaminants, heavy metals, pesticides and allergens. 

Available clinical studies and meta-analyses have notably examined astaxanthin's effect on markers of oxidative stress. A meta-analysis of randomised trials showed a significant reduction in malondialdehyde, a marker of lipid peroxidation. 

Astaxanthin from Haematococcus pluvialis is authorised for use in food supplements in the European Union, with a maximum dose of 8 mg/day for people over 14. EFSA concluded that this intake is safe for adults. (efsa.onlinelibrary.wiley.com)

Marine omega-3 EPA and DHA are fatty acids essential to the proper functioning of the body. Our formula uses Omegatex® concentrated fish oil from Solutex, rich in EPA and DHA, in triglyceride form.

DHA contributes to the maintenance of normal brain function and normal vision. EPA and DHA together contribute to the normal function of the heart. These beneficial effects are obtained with a daily intake of 250 mg of DHA for the brain and vision, and 250 mg of EPA + DHA for the heart. 

Beyond these recognised functions, clinical research continues to explore the benefits of omega-3s in brain ageing. A meta-analysis published in 2024 suggests a benefit for certain cognitive functions in people without dementia, with effects depending notably on the dose and initial omega-3 status. 

Omegatex® oil is obtained using Solutex purification technologies, including Flutex®, which notably uses supercritical CO₂ to extract, purify and concentrate the fatty acids, and Cleantex®, which limits oxidation and reduces contaminants as well as any residual fishy taste.

Iron is an essential mineral that contributes in particular to the normal formation of red blood cells and haemoglobin, normal oxygen transport, the normal function of the immune system, normal energy-yielding metabolism and the reduction of tiredness and fatigue. 

Our formula uses Ferrochel®, a chelated iron bisglycinate developed by Balchem (formerly Albion Minerals). In this form, the iron is bound to two glycine molecules. This structure improves its digestive stability, bioavailability and tolerance compared with conventional iron salts. 

Clinical studies on iron bisglycinate show, among other things, better absorption in certain food matrices. In one study in adults, iron bisglycinate absorption from a phytate-rich meal was around 4 times higher than that of ferrous sulphate, while still being regulated by the body's iron stores. 

Another study in 74 subjects found Ferrochel® absorption to be around 2 times higher than ferrous sulphate across different breakfasts, with lower sensitivity to the inhibitory effect of phytates. 

In 145 pregnant women, supplementation providing 15 mg/day of iron as Ferrochel® was compared with 40 mg/day as ferrous sulphate. Despite the lower iron dose, the Ferrochel® group showed less iron depletion, with better adherence reported in this study. 

Spirulina (Limnospira platensis, formerly Arthrospira platensis) is a microalga naturally rich in protein, pigments and micronutrients.

Our organic spirulina is grown in Spain by Blauver in Almacelles, in the Lleida region. It is certified under EU organic farming standards and is made from 100% organic spirulina. 

Its biomass contains around 62 to 68% protein and 18 to 30% phycocyanin, as well as carotenoids and chlorophyll. Blauver uses a low-temperature drying process designed to best preserve the nutritional quality of the biomass. 

Spirulina is the subject of extensive research on lipid metabolism, oxidative stress, recovery and energy metabolism. Several recent reviews report favourable signals on certain cardiometabolic and antioxidant markers, while highlighting the heterogeneity of doses and protocols. 

The quality of spirulina is also a key issue. Blauver raw material is tested in particular for heavy metals, pesticides, aflatoxins, microcystins and microbiological contaminants.
