Magnesium Deficiency in Europe — Key Statistics 2026
Magnesium is involved in over 300 enzymatic processes — and is one of the most underestimated nutrient deficiencies in Europe. According to the German National Nutrition Survey II (NVS II), 26% of men and 29% of women in Germany do not meet the DGE recommendation. European population studies estimate that 10–30% of the population has clinically relevant insufficiency [Rosique-Esteban et al. 2018]. This page aggregates verified figures from NVS II, EFSA, DGE, and peer-reviewed literature.

Key Figures at a Glance
| Indicator | Value | Group / Region | Source |
|---|---|---|---|
| Intake below DGE reference, men | 26% | Adults DE (NVS II, n ≈ 20,000) | MRI NVS II 2008 |
| Intake below DGE reference, women | 29% | Adults DE (NVS II) | MRI NVS II 2008 |
| Clinically relevant insufficiency, Europe | 10–30% | General population, Europe | Rosique-Esteban et al. 2018 |
| DGE reference value (men 25–51 y.) | 350 mg/day | D-A-CH reference values 2021 | DGE 2021 |
| DGE reference value (women 25–51 y.) | 300 mg/day | D-A-CH reference values 2021 | DGE 2021 |
| Mean intake men (Germany) | 323 mg/day | Adults DE (NVS II) | MRI NVS II 2008 |
| Mean intake women (Germany) | 261 mg/day | Adults DE (NVS II) | MRI NVS II 2008 |
Insufficiency by Age Group (NVS II)
The NVS II (2008, n ≈ 20,000) is the most comprehensive nationally representative dietary survey in Germany. Adolescents and young women as well as older adults show the highest rates of insufficient magnesium intake.
| Age group | Men < reference | Women < reference | Source |
|---|---|---|---|
| 14–18 years | ~56% | ~53% | MRI NVS II 2008 |
| 19–24 years | ~32% | ~42% | MRI NVS II 2008 |
| 25–50 years | ~22% | ~27% | MRI NVS II 2008 |
| 51–64 years | ~21% | ~24% | MRI NVS II 2008 |
| 65+ years | ~29% | ~35% | MRI NVS II 2008 |
Structural Problem: Soil Depletion and Processing Losses
The decline of magnesium content in soils and foods is a Europe-wide documented phenomenon. Intensive agriculture, acid rain, and high nitrogen fertilisation have reduced magnesium levels in cropland soils across parts of Europe over decades. Food processing further compounds the problem.
Whole wheat contains ~138 mg/100 g Mg; white flour (type 405) only ~22 mg/100 g — a loss of approximately 80%.
Boiling vegetables in water can leach up to 75% of magnesium into the cooking water [Vormann 2003].
Typical magnesium absorption in healthy adults is 30–50% — meaning dietary intake recommendations already account for this [EFSA 2015].
