Cytrynian magnezu luzem z magazynu EU — ≥98%, 25 kg minimum. Porównanie 7 form, animowane słupki wchłaniania, kliniczny przewodnik dawkowania i interaktywny kalkulator elementarnego Mg.
Magnez musi być w formie rozpuszczonej (Mg²⁺) aby zostać wchłonięty. Przy jelitowym pH 5–7, tlenek Mg jest praktycznie nierozpuszczalny — 10 000× mniej niż cytrynian Mg przy pH 7. Anion cytrynianu tworzy stabilny kompleks wodnorozpuszczalny z Mg²⁺ stabilny przez cały zakres pH przewodu pokarmowego.
| Form | Bioavailability | Elemental % | GI Tolerance | Best For | Evidence | Verdict |
|---|---|---|---|---|---|---|
| Magnesium Citrate ★ BEST | 16.2% | General health, sleep, constipation, sports | ★★★★★ | Best all-round form — high bioavailability, excellent tolerability, proven efficacy | ||

| EU regulatory status | ✓ Safe — Food supplement ingredient. No E-number. Permitted under EU 1170/2009 (nutrient sources in food supplements). |
| EFSA tolerable upper intake | ✓ Safe — 350 mg/day elemental Mg from supplements (food sources excluded). EU 1169/2011 NRV = 375 mg/day. |
| Overdose (supplemental) | ⚠ Caution — Above 350–400mg elemental Mg from supplements → osmotic diarrhea. No systemic toxicity in healthy individuals. |
| Kidney disease | ⚠ Caution — Renal impairment: kidneys cannot excrete excess Mg → hypermagnesemia risk. Medical supervision required. |
| Drug interactions | ⚠ Caution — Reduces absorption of: bisphosphonates, fluoroquinolones, tetracyclines, levodopa. Take 2h apart. Thiazide diuretics increase renal Mg loss. |
| Pregnancy | ✓ Safe — Safe at RDA levels (270–350mg/day elemental). Used clinically as tocolytic (IV MgSO4) to delay premature labour. |
| Allergens | ✓ Safe — Not a listed allergen (EU 1169/2011). Vegan, non-GMO, halal/kosher suitable. |
