Kim Kardashian and Joe Rogan beloved supplement may speed up cancer growth

Key Points:

• Supplements that increase NAD+ levels, popular among celebrities for their anti-aging benefits, may inadvertently support cancer survival and resistance to treatment, according to new research.
• NAD+ precursors like nicotinamide mononucleotide (NMN), nicotinamide riboside (NR), and niacinamide (NAM) help maintain cellular energy and repair but can also "supercharge" cancer cells, making tumors more resilient.
• The study focused on pancreatic cancer cells, revealing that NAD+ supplements strengthened tumors by reducing oxidative stress and blocking chemotherapy-induced cell death, potentially undermining cancer treatments.
• Since most NAD+ supplement users are older adults—who are at higher risk for cancer—researchers urge caution, especially for cancer patients undergoing chemotherapy, as these supplements may worsen outcomes.
• Experts recommend that doctors routinely inquire about NAD+ precursor supplement use in cancer patients to avoid unintended interference with treatment efficacy.
