Best time to take Iron Bisglycinate

Written to our editorial standards · reviewed against published research· Updated 2 Jun 2026
Morning, empty stomach, with vitamin C

Take iron in the morning on an empty stomach with vitamin C, away from coffee, tea, and calcium.

Iron absorbs best in an acidic, empty stomach, and vitamin C boosts uptake several-fold. Coffee, tea, dairy, calcium, and high-fibre foods all block it, so they must be kept apart from your iron dose.

When
Take in the morning
With food?
Empty stomach, away from coffee, tea, dairy and calcium
Typical dose
25 mg
How to take it

Take it with a small glass of orange juice or about 200 mg of vitamin C, 30 minutes before food. Keep coffee, tea, and calcium at least 2 hours away. Every-other-day dosing can actually absorb better and is gentler.

Watch out

If iron upsets your stomach, a gentle form like bisglycinate with a small low-calcium snack is a fair compromise.
