- Disabled macroautophagy
- Inflammaging
- Altered cellular communication
- Mitochondrial dysfunction
The Role of Trehalose in Aging and Longevity
Trehalose is a naturally occurring sugar made of two glucose molecules (a non-reducing disaccharide). It is found in foods such as mushrooms, seaweed, and yeast, and it is also produced by many bacteria, fungi, plants, and some invertebrates, where it can function as an energy reserve and stress-protective carbohydrate.
In humans, trehalose is broken down by the enzyme trehalase during digestion. Beyond its nutritional role, trehalose has been widely studied in preclinical research for its potential effects on cellular stress pathways involved in aging biology, including proteostasis and autophagy-related processes.
Trehalose Versus Sucrose
Sucrose is another common naturally occurring disaccharide found in fruits and vegetables, and it is the main constituent of table sugar. Unlike trehalose (glucose + glucose), sucrose is composed of one glucose molecule and one fructose molecule.
The two sugars are also broken down differently. Trehalose is split by trehalase, an enzyme concentrated in the small intestine, while sucrose is split by sucrase. That difference in digestion is one reason trehalose has drawn research interest.
Trehalose and Longevity
Trehalose has been studied for its potential to influence core biology-of-aging pathways, largely through preclinical research. In the nematode Caenorhabditis elegans, trehalose treatment starting in early adulthood extended mean lifespan by 32%, alongside improvements in several age-associated measures linked to stress resistance and protein homeostasis (R).

Trehalose and Brain Health
Trehalose and Kidney Health
Kidney function gradually declines with age, and age-related kidney changes are often linked to higher oxidative stress and impaired cellular stress resilience. Because the kidney is highly metabolically active, oxidative damage can contribute to progressive functional decline over time.
In aged rat models, trehalose supplementation has been studied for potential antioxidant and stress-response effects in the kidney. In one study, daily trehalose supplementation for one month was reported to improve kidney antioxidant defenses, including changes in pathways involving NFE2L2 (Nrf2), catalase, and superoxide dismutase, key components of the cellular response to oxidative stress. (R)
In a separate study in aged rats, trehalose supplementation was associated with lower markers of oxidative stress and inflammation in kidney tissue, alongside changes linked to SIRT1, a protein involved in stress-response regulation and cellular maintenance. (R)
Trehalose and Liver Health
Aging is associated with changes in liver metabolism and a higher risk of conditions such as non-alcoholic fatty liver disease (NAFLD). Age-related shifts in lipid handling, cellular stress responses, and inflammation can contribute to fat accumulation and functional decline over time.
In preclinical aging models, trehalose supplementation has been studied for its potential effects on liver metabolic and stress-response pathways. In aged animals, trehalose has been reported to influence signaling linked to lipid metabolism and to reduce markers of hepatic lipid accumulation, with effects discussed in the context of pathways such as SIRT1/AMPK and lipid-regulatory transcription factors. (R)
In older mice, trehalose supplementation has also been reported to reduce hepatic endoplasmic reticulum stress and inflammatory signaling, while supporting cellular protein homeostasis (proteostasis) in liver tissue. (R)
The Impact of Trehalose on Human Health
Human research on oral trehalose has primarily studied daily intakes of approximately 3.3 g per day, typically over a 12-week period, with outcomes focused on inflammation and cardiometabolic biomarkers.
A full daily serving of NOVOS Vital provides 4 g of trehalose, a dose closely aligned with human clinical research.
In a double-blind, randomized, placebo-controlled trial in adults with type 2 diabetes, 3.3 g per day of oral trehalose for 12 weeks was associated with a reduction in hs-CRP, a marker of systemic inflammation, compared with placebo (R).
Additional clinical research is underway evaluating 3.3 g per day of trehalose for 12 weeks in recovery settings, with endpoints including CRP, IL-6, TNF-α, and wound-healing indices. Results from this trial will help further clarify trehalose’s effects on inflammatory and recovery-related biomarkers in humans (R).
Overall, the current human evidence on oral trehalose is based on studies using daily intakes close to one NOVOS Vital serving. These trials suggest trehalose may support inflammation-related biomarkers in specific populations, while additional research is ongoing to clarify its broader effects on health outcomes.
