Wonderfeel, a longevity-focused wellness biosciences company founded in San Francisco in 2018, has reached two notable milestones according to the company. First, its peer-reviewed clinical brief titled Real-world User-reported Benefits of a Multi-ingredient NMN-based Supplement Targeting Age-related Decline was published in the July 2025 issue of the International Journal of Nutrition and Food Sciences according to the company.
The brief, co-authored by its chief medical officer, Dr Andrew Salzman, and director of research and development, Dr Luis Cifuentes, presents observational data from user-reported surveys. The company said that 66.8% of users experienced noticeable changes such as more energy, clearer thinking, better sleep and healthier-looking skin, while improvements were also noted in nervous system function (81%), skin, muscle, joint, digestion and hormone-related responses. According to the company, 45% reported increased energy, 16% better sleep, 14% greater focus and clarity, and only 1.5% reported mild side effects with none linked to the supplement. A randomized, controlled clinical trial is planned as the company’s next step according to the company.
Simultaneously, Wonderfeel’s flagship formula, Wonderfeel Youngr™ NMN, earned Bronze in the Improved Energy & Vitality category at the 2025 Wellness From Within Awards, a UK-based program highlighting products with science-based wellness impact according to the company.
The company positions itself as bridging longevity research and everyday wellness through science-backed supplements and functional foods, and emphasizes its commitment to sustainability via minimal, eco-friendly packaging.
