Precision supplement timing
When should you take iron supplements?
- When is the best time to take vitamin D? With your largest meal of the day, ideally morning. Dietary fat boosts absorption up to 32%.
- When should you take iron supplements? On an empty stomach with vitamin C, away from coffee, tea, calcium, and dairy.
- When is the best time to take magnesium? Evening, 1 to 2 hours before bed, and not in the same dose as zinc or calcium.
- When should you take zinc? With food to avoid nausea, separated from iron, calcium, and magnesium by 2+ hours.
- When is the best time to take calcium? Split doses with meals, never with iron, and away from your thyroid medication.
