Note

Magnesium citrate: GI sensitivity

Magnesium citrate can cause loose stools in some people, especially at doses above 200 mg. Start low and build up. If you're GI-sensitive, consider switching to magnesium glycinate.

Pre-check is rule-based, not medical advice. Consult a healthcare professional for personalised guidance.

Interaction Analysis

Pharmacokinetic + pair-level checks

1 caution

Caution

High-dose Magnesium + Calcium: absorption competition

Magnesium and calcium use overlapping intestinal transport pathways. Very high doses of both simultaneously can reduce net absorption of each. Optimal Ca:Mg ratio is approximately 2:1.

→Space them 2 hours apart, or maintain a 2:1 calcium-to-magnesium ratio.

Timing optimizations

Creatine Monohydrate

Post-workout or with carbohydrate

Insulin-mediated creatine uptake. Post-workout carbohydrate enhances muscle creatine loading. Timing matters less for maintenance. (Onset: ~1h, half-life: ~3h)

Taurine

Take ~1h before the intended effect window

Reaches peak plasma concentration in ~1h. Half-life ~1.5h.

Glycine

Before bed

Glycine lowers core body temperature and improves slow-wave sleep. 3g ~30–60 min before bed is the studied dose. (Onset: ~30 min, half-life: ~2h)

L-Lysine

Take ~1h before the intended effect window

Reaches peak plasma concentration in ~1h. Half-life ~1.5h.

Vitamin C (Ascorbic Acid)

Take ~2h before the intended effect window

Reaches peak plasma concentration in ~2h. Half-life ~2h.

L-Theanine

Take ~1h before the intended effect window

Reaches peak plasma concentration in ~1h. Half-life ~2.5h.
