Le NMN liposomique a montré des niveaux plus élevés de NAD+ dans une nouvelle étude humaine
A recent 2025 human study compared liposomal NMN with regular non-liposomal NMN and placebo over a period of 4 weeks. The researchers wanted to see how the different forms affected NAD+ levels in the blood — a molecule involved in cellular energy production and mitochondrial activity, which naturally declines with age. The result? Participants taking […]
Étude : facteurs de risque d'AVC, de démence et de dépression chez les personnes âgées
Brain health is often linked to age and genetics, but research shows that the picture is more flexible. A large 2025 study published in the Journal of Neurology, Neurosurgery & Psychiatry identified several modifiable risk factors shared by stroke, dementia, and late-life depression — suggesting that some aspects of brain health may be influenced long […]
Étude insight : Le resvératrol protège la peau de l'intérieur vers l'extérieur
As we age, changes in the skin become more visible. Fine lines deepen, skin tone may appear less even, and the skin often feels drier over time. While these changes are a natural part of aging, interest in methods that help reduce visible signs of skin aging remains high. Each year, significant resources are invested […]
Lorsque les cellules perdent du NAD⁺ : Une nouvelle étude révèle une réponse surprenante de type viral
A recent study published in Aging Cell in 2025 offers detailed insight into what happens when cells lose their supply of NAD⁺, one of the body’s most essential molecules for energy and repair. The researchers found, among other things, that when cells lose NAD⁺, they don’t just slow down — they activate a defense mechanism […]
Étude sur l'alpha-cétoglutarate : la molécule oubliée qui pourrait vous aider à mieux vieillir
Scientists from the Vrije Universiteit Amsterdam recently published a comprehensive review titled “Alpha-Ketoglutarate dietary supplementation to improve health in humans [1].” In it, they explore a question that has been quietly shaping the field of longevity research: could a simple molecule that our body already produces be one of the keys to staying healthy as we age? table […]
Le resvératrol et la santé osseuse : étude menée auprès de femmes ménopausées
As women age, their bones gradually lose density. This process accelerates after menopause, when oestradiol levels drop and the balance between bone building and bone breakdown shifts [1]. The result can be a slow but steady weakening of the skeleton, often leading to osteoporosis and an increased risk of fractures later in life. table of contents […]
Vitamine D3 et vieillissement biologique : ce qu'une étude de 4 ans révèle sur les télomères
We know vitamin D as the “sunshine vitamin” that supports bone strength, immunity, and overall vitality. But new scientific evidence suggests it may also play a role in how we age at a cellular level. A major new study from 2025 published in The American Journal of Clinical Nutrition examined whether daily vitamin D3 (2,000 […]
Étude : Comment le GlyNAC améliore les signes du vieillissement chez les personnes âgées
table of contents The global population is aging rapidly. By 2050, more than 20% of people worldwide will be over the age of 60. WHO, 2024 This shift brings clear challenges for health systems – but it also highlights something more fundamental: the importance of maintaining health, not just extending life. Healthy longevity isn’t achieved […]
Essai clinique : Les oméga-3, la vitamine D et l'exercice physique peuvent-ils ralentir le vieillissement biologique ?
Introduction The way we live each day affects our long term health and longevity. Smaller choices like what we eat, including Omega-3 and Vitamin D, and how active we are through exercise can have a lasting impact on our bodies. As interest in aging well grows, scientists are looking into how lifestyle changes can lead […]
