When should you take supplements around a workout?
Timing around training is about windows, not the clock. Many people take fat-soluble vitamins and omega-3 with a post-workout meal, keep stimulating supplements before training rather than after, and place magnesium in the evening to align with winding down. None of this needs a change to what you take, only when.
Before, during, after
Before: stimulating supplements like B-complex or rhodiola, if you use them, fit pre-training. During: water and electrolytes for longer sessions. After: a meal with fat carries fat-soluble vitamins and omega-3, and protein supports recovery if that is part of your routine.
What suits a post-workout meal
Fat-soluble vitamins (A, D, E, K), omega-3, CoQ10, and any multivitamin that contains them. The fat in the meal is what they need to absorb properly.
Evening recovery window
Magnesium glycinate, glycine and similar calming supplements belong in the wind-down window, regardless of when you trained. Move them away from a late session by at least an hour.
What does not need timing
Creatine works on a saturation basis, so the time of day matters less than taking it daily. Vitamin C and most B vitamins are fine in the morning whether or not you train that day.
Frequently asked
Should I take magnesium before training?
Most people prefer it in the evening. Calming supplements just before training can blunt the session.
Does pre-workout caffeine clash with anything?
Yes, with iron and with calming adaptogens. Space iron by an hour and keep ashwagandha or l-theanine outside the pre-training window.
Is fasted training a problem for supplements?
Only for fat-soluble vitamins, which want a meal. Take them with your first proper meal after the session, not before it.
