Commencer à prendre du retard à 30 ans ? Le NAD+ de votre corps pourrait sonner l'alarme...
Selon les dernières recherches publiées dans des revues faisant autorité telles que *Nature Metabolism*, les données métabolomiques humaines montrent des changements spectaculaires non linéaires entre 30 et 50 ans. Ceux-ci incluent un déséquilibre du métabolisme lipidique, une synthèse de collagène altérée et une forte baisse de l'activité de la télomérase. Tous ces changements sont étroitement liés à la baisse des niveaux de NAD+.
Ressentez-vous aussi cela ?
- Après 30 ans, rester debout tard entraîne une récupération beaucoup plus lente.
- Les courbatures après l'exercice mettent plus de temps à disparaître.
- Memory and concentration aren’t what they used to be.
- L'état de la peau se dégrade, avec l'apparition progressive de ridules et d'un teint terne.
These changes may not be simply the “natural phenomenon of aging,” but rather your body sending a warning — your NAD+ (Nicotinamide Adenine Dinucleotide) levels are dropping.
PARTIE 01
NAD+: The Body’s “Youth Energy Currency”
Le NAD+ est la molécule centrale du métabolisme énergétique cellulaire, impliquée dans plus de 300 réactions biochimiques, notamment :
- Production d'énergie (fonction mitochondriale)
- Réparation de l'ADN (prévention de l'accumulation de dommages cellulaires)
- Activation des protéines anti-âge (Sirtuines, régulation de la longévité)
- Régulation du rythme circadien (affectant le sommeil et le métabolisme)
Les recherches de la Harvard Medical School montrent qu'après 30 ans, les niveaux de NAD+ chutent fortement, diminuant d'environ 50 % tous les 20 ans. Ce déclin impacte directement le métabolisme énergétique, la réparation de l'ADN et les mécanismes de défense cellulaire.
- Ages 20–30: NAD+ levels remain relatively stable
- Ages 30–50: Decline by about 2–3% annually
- After 50: Only 25–50% of youthful levels remain
Changements corporels typiques après 30 ans :
Changements métaboliques :
Basal metabolic rate decreases by 1–2% per decade. Muscle mass begins to decline by 0.5–1% annually from age 30, while visceral fat accumulates more easily. Abdominal fat increases by 0.5–1 kg per year on average after 30.
Changements endocriniens :
Chez les hommes, les niveaux de testostérone diminuent d'environ 1 % par an. Chez les femmes, les œstrogènes commencent à fluctuer de manière significative vers 35 ans. Cela entraîne une baisse de la libido, des difficultés de synthèse musculaire et des sautes d'humeur.
Changements cognitifs :
The hippocampus shrinks by about 0.5% annually after 30. Memory, reaction speed, and ability to learn new things gradually decline. Research shows that after 30, learning a new skill requires 20–30% more effort compared to the 20s.

Comment augmenter le NAD+ ? Une comparaison scientifique entre NMN et NR
Currently, the two mainstream approaches to boosting NAD+ are NMN (β-Nicotinamide Mononucleotide) and NR (Nicotinamide Riboside), both of which are NAD+ precursors with unique characteristics.
NMN: The efficient yet debated “star molecule”
NMN is a natural direct precursor of NAD+ in the human body, featuring rapid absorption and high conversion efficiency. Studies show that sublingual administration allows NMN to enter the bloodstream within 2–3 minutes and significantly raise tissue concentration in just 15 minutes — making it one of the most effective known NAD+ supplementation methods.
From a global regulatory perspective, NMN is transitioning from dietary supplement to pharmaceutical. Japan, as a pioneer, approved NMN as a food ingredient in 2020. In the U.S., due to changes in drug development regulations, NMN is currently limited to clinical studies. In China, NMN is only allowed in cosmetics, with food use still under review. These regulatory differences highlight NMN’s potential while underscoring the need for more safety data.
Notably, 87 clinical trials on NMN are ongoing worldwide, with China accounting for 41% of them. This suggests promising prospects in healthy aging. As more clinical data accumulate, NMN’s application framework is expected to become clearer within 3–5 years, providing new options for anti-aging interventions. Consumers are advised to follow policy updates and prioritize certified products. BonTai Biotech (BONTAC), a pioneer in NMN, has passed SELF GRAS safety certification, pioneered full enzymatic production technology, and ensures high-quality raw material and stable supply, partnering with many nutrition brands nationwide.
NR : Le choix sûr pour la supplémentation en NAD+
NR, an important member of the Vitamin B3 family, is showing steady market growth. As a natural compound composed of ribose and nicotinamide, it is found in meat, fish, and grains. Its structure is nearly identical to NMN, differing by just one phosphate group. Metabolically, NR works mainly through the pathway NR → NMN → NAD+. While its conversion efficiency (60–70%) is lower than NMN, NR offers superior safety, fewer metabolic by-products, and more balanced tissue distribution.
NR has been widely recognized in major global markets: the U.S. FDA has granted GRAS status (allowing daily supplementation up to 300 mg); the EU has approved it as a Vitamin B3 source with a daily adult limit of 300 mg; Australia regulates it as a special medical food; and Canada classifies it as a natural health product. Importantly, Bontac® owns the world’s first crystalline patent for NR Hydrogen Malate, ensuring greater purity and stability.

Quatre stratégies scientifiques pour augmenter le NAD+
1. Supplémentation ciblée avec des précurseurs du NAD+ :
- NMN (250–500 mg/day, sublingual absorption is better)
- NR (300 mg/jour, adapté à une utilisation à long terme)
2. Exercice pour activer la synthèse du NAD+ :
- L'entraînement par intervalles à haute intensité (HIIT) stimule la production de NAD+
- L'entraînement en résistance maintient la masse musculaire et retarde le déclin métabolique
3. Optimisation alimentaire :
- Aliments riches en précurseurs du NAD+ : avocat, saumon, brocoli
- Le jeûne intermittent (16:8) active les voies de longévité des sirtuines
4. Ajustements du mode de vie :
- Deep sleep (7–8 hours) promotes NAD+-related repair
- Réduire la consommation d'alcool et de sucre diminue la consommation de NAD+
Turning 30 is not the end — it’s the best starting point for investing in health! The decline of NAD+ is a key driver of aging, but with scientific interventions, we can slow down this process. Choosing the right supplementation (NMN or NR) combined with a healthy lifestyle helps the body stay youthful!
