This advice is based on the fundamental principle of 'prioritizing the foundations' in wellness, which is widely supported by the scientific community. Meta-analyses consistently confirm that nutrients from whole foods are better absorbed and exhibit a complex synergy that isolated supplements cannot replicate (source: Harvard T.H. Chan School of Public Health, observational consensus). The idea that lifestyle habits (sleep, exercise, nutrition) constitute the cornerstone of health is validated by numerous interventional studies (RCTs) showing benefits superior to any isolated supplementation. However, the advice is slightly exaggerated in suggesting total exclusion. There are documented exceptions where supplementation is clinically relevant, such as vitamin D in countries with little sunlight or vitamin B12 for vegan diets (source: Cochrane Reviews, meta-analyses). The message is therefore an excellent reminder against reliance on miracle products, although it simplifies a reality where certain specific needs can persist despite a healthy lifestyle.

Needlessly delaying bedtime ("bedtime procrastination") is framed here as coming from not having processed the day's emotions — working through them before bed supposedly helps you fall asleep.

Before buying another supplement, audit what you're already taking — most well-fed adults are already covered, and the real question isn't which one to buy but whether you actually have a shortfall worth correcting.
