Yes, we have chosen to create the simplest possible formulations with as many naturally derived ingredients as possible, highly concentrated and scientifically documented for their effectiveness and safety.

NMN is a precursor to NAD+, a key molecule for cellular metabolism and longevity. It supports cellular energy, DNA repair, and cognitive function. It is the ultimate molecule for healthy aging.

We use pharmaceutical grade NMN (≥99% purity) in our Reverse powder.
Studies conducted by Harvard Medical School (Dr. David Sinclair) have shown that NMN increases levels of NAD+, a coenzyme essential for energy metabolism, DNA repair, and cellular longevity.

Our Reverse capsules of pure resveratrol (>98%) are extracted from Polygonum cuspidatum and standardized. They are microencapsulated for improved bioavailability and oxidative stability.
Resveratrol is known to activate sirtuins (SIRT1), enzymes linked to longevity, and protect against oxidative stress.

We use AstaPure®, a natural astaxanthin extracted from the red algae Haematococcus pluvialis, grown in a closed environment without pesticides. It's this algae that gives our Glow powder its color.
It is one of the world's most powerful natural antioxidants, 6000x more powerful than vitamin C against free radicals.

We use Naticol®, a hydrolyzed marine collagen produced by Weishardt (France) from 100% traceable fish, using a patented enzymatic process. It has a neutral taste and dissolves easily (unlike other collagens). This collagen has 7 clinical studies, is made in France, and has a high absorption (2,000 daltons).
Clinical studies show an improvement in skin elasticity and a significant reduction in wrinkles after 8 weeks. And for guaranteed effectiveness, we have chosen to offer you the maximum amount per dose, i.e. 11.5g of collagen per dose, which will be reinforced by the effect of astaxanthin and hyaluronic acid.

It is a low molecular weight hyaluronic acid, developed by Roelmi HPC (Italy), which promotes rapid absorption and a moisturizing effect from within.
Studies show improved skin firmness, reduced wrinkles and strengthened joints after 4-6 weeks.

Effects vary depending on the individual and the product. Some experience an improvement in vitality or skin quality within a few weeks. For profound longevity-related effects, regular long-term use is recommended. The NAD tests we will soon be offering are a good way to check the effectiveness of the molecules in the REVERSE range because they give you an estimate of your cellular age.

Yes, they are specially formulated to support healthy aging.

From the age of 25, our natural collagen production decreases, and from the age of 30, our cells no longer renew themselves as well. We recommend starting supplementation at the first signs, but the advantage of our different ranges is that they can be taken from any age and the first effects will be felt after several weeks.

In case of chronic illnesses or medical treatment, seek the advice of your healthcare professional.

Absolutely. Our products comply with European regulations, are manufactured according to Good Manufacturing Practices (GMP), and are tested for purity.
