*These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease. Studies linked on this site tested individual ingredients, not finished Winks.

Research sources and testing details
Research on sleep and health — not results from taking Winks. Heart health: Under 6 hours of sleep vs. 6⁠–⁠9 hours. Body composition: Sleep research during calorie restriction. Longevity: Five healthy sleep factors vs. zero or one. Immunity: 5–6 hours of sleep vs. more than 7 hours. *Sleep-research figures on this site come from published research on sleep, not from studies of Winks; they show associations, not proven cause. Sources: Heart health · Body composition · Lifespan · Immune function. Quality results: Goodnight Grape, lot 2521665. Melatonin reported at less than 5.00 mcg/g by UPLC (Eurofins report 5360280-0, May 11, 2026), the lab’s reporting limit, not a claim of absolute zero. Arsenic, cadmium, lead and mercury were below the manufacturer’s listed limits, and total plate count, yeast and mold, E. coli and Salmonella passed the manufacturer’s specifications (Catalyst certificate of analysis, April 16, 2026). Lot results verify quality checks, not sleep results. Sleep-mechanism descriptions follow the general sleep science described by Dr. Todd Born, ND, CNS, who formulated Winks; general sleep science, not a Winks result. “What to expect” milestones are routine milestones, not promised results; ingredient studies did not test the finished Winks formula. Comparisons are with melatonin-only supplements; combination formulas vary, and ingredient research does not establish superior results for Winks.

Sleep and health research:* Relative risk differences associated with healthier sleep in observational studies. These studies did not test Winks or establish cause and effect. These percentages are relative differences, not percentage-point reductions or the share of people who benefit. Three analyses use overlapping UK Biobank populations.
