Harper's Bazaar Details 3-Part Supplement Timing Plan for Better Absorption

1 articles · Updated · Harper's BAZAAR · May 28

A Harper's Bazaar guide says supplement timing and food pairing can materially affect absorption, urging users to split intake across three windows: morning, midday and evening.
Iron is best taken on an empty stomach with vitamin C, while coffee and tea should wait because caffeine can interfere with absorption; probiotics also fit before breakfast.
Midday is recommended for zinc with a snack to limit nausea, and fat-soluble vitamins A, D, E and K absorb better with healthy fats rather than on an empty stomach.
At night, omega-3s and multivitamins are better tolerated with a larger meal, while some magnesium forms taken 60 to 90 minutes before bed may aid bowel regularity or sleep.
The guide adds that delivery format matters—drops, nasal sprays and liposomal products can improve uptake—and warns that minerals such as iron, zinc, magnesium and calcium may compete when taken together.
