Nestlé Research Highlights Potential of NAD+ Boosters for Cellular Health and Microbiome Support

Nestlé has unveiled new clinical research suggesting that specific nicotinamide adenine dinucleotide (NAD+) precursors can enhance cellular energy levels and positively influence gut microbiome activity. This research positions healthy longevity as a core growth area for the food and nutrition giant.

Study Details and Findings

The study, conducted by scientists at the Nestlé Institute of Health Sciences and published in Nature Metabolism on January 15, 2026, compared three NAD+ precursors – nicotinamide riboside (NR), nicotinamide mononucleotide (NMN), and nicotinamide (Nam) – in a randomized, open-label, placebo-controlled study involving 65 healthy adults over 14 days.

Researchers discovered that supplementation with NR and NMN led to comparable increases in circulating NAD+ concentrations, even as nicotinamide (Nam) did not demonstrate the same effect. The study revealed that both NR and NMN interacted with gut microbiota, resulting in the production of nicotinic acid (NA) and enhanced microbial activity. This suggests potential health benefits extending beyond cellular energy metabolism.

The Role of NAD+ in Healthy Aging

NAD+ is a crucial co-enzyme involved in vital cellular processes, including energy production and DNA repair. Research indicates that NAD+ levels naturally decline with age and are associated with age-related conditions such as cognitive decline, muscle loss, and cardiovascular dysfunction. Pathways to restore or maintain NAD+ levels have become a focal point in the rapidly expanding longevity and healthy aging market.

Gut Microbiome Connection

The study highlighted a gut-dependent model for the action of these precursors. NR and NMN appear to elevate circulatory NAD+ via the Preiss–Handler pathway, while rapidly absorbed Nam acutely affects NAD+ levels through the salvage pathway. Importantly, the research identified that NR and NMN are converted into nicotinic acid (NA) by gut microbiota, and NA itself is a potent NAD+ booster. This suggests a dual effect of NR and NMN: a sustained increase in systemic NAD+ levels and a positive modulation of gut health.

Nestlé’s Strategic Focus on Longevity

Nestlé has identified healthy longevity as a key strategic growth pillar and is actively expanding its research and development capabilities in biotechnology and clinical research to accelerate innovation in this area. Nestlé anticipates that these findings will influence formulation strategies within the functional nutrition category, potentially leading to next-generation bioactives focused on cellular health.

Industry Implications

The longevity market, encompassing supplements, functional beverages, and medical nutrition, is attracting significant investment due to aging populations in North America, Europe, and Asia. This growing demand is driving a necessitate for preventative health solutions. For ingredient suppliers and contract manufacturers, this shift may lead to higher barriers to entry but as well increased opportunities in clinically validated, premium-priced formulations targeting aging consumers.

Trigonelline as an Additional NAD+ Precursor

Further research, published in Nature Metabolism on March 19, 2024, identifies trigonelline, a natural alkaloid, as another NAD+ precursor that can improve muscle function. Studies display that dietary supplementation of trigonelline enhances muscle strength and prevents fatigue during aging, operating through an NAD+-dependent mechanism.

This research underscores the growing convergence between food, supplements, and biotechnology in the pursuit of advancements in the global healthy-aging economy.
