  • Absorbed dose vs reference intake1.0magnesium: the serving is 1.7× the upper level (250 mg)
  • Completeness for the purpose0.7For “sleep, stress, cramps” — 71 %; without B6 — magnesium works, but B6 helps retain it in cells; could be added without conflict: vitamin b6; a formula with one main purpose
  • Safety and purity0.4Magnesium: the serving is above the upper level — only on medical advice; debatable ingredient groups: titanium dioxide (E171)

Free from:
  • glutenmatters for coeliac disease and gluten intolerance
  • wheatone of the common food allergens
  • milkmatters for milk-protein allergy and lactose intolerance
  • soya common allergen; soy lecithin is often in coatings
  • yeastmatters for yeast intolerance
  • sugarmatters for diabetes and carb counting
  • sodium (salt)matters when limiting salt, for example with blood pressure
  • artificial sweeteners · by the listthe list has no ingredient of the “acesulfame potassium, aspartame, sucralose” group — a calorie-free sweetener, usually paired with sucralose or aspartame for taste. Permitted, a preference question.
  • colorants E102/E120/E150 · by the listthe list has no ingredient of the “caramel colour, carmine, tartrazine” group — a brown colour from caramelised sugar: it tints syrups and coatings and does not affect the action.
  • carrageenan · by the listthe list has no ingredient of the “carrageenan” group — a thickener from red seaweed. It is permitted but debated: in animal studies the degraded form irritated the gut, so people with inflammatory bowel disease are sometimes advised to avoid it. For food-grade carrageenan there is no such proof.
  • gelatin · by the listthe list has no ingredient of the “gelatin (capsule)” group — capsule shell of animal gelatin (usually bovine or fish) — not for vegetarians; for halal/kosher the source must be confirmed with the maker
  • soy lecithin · by the listthe list has no ingredient of the “soy lecithin” group — an emulsifier from soy: it binds fats with water and keeps a capsule from separating. With a soy allergy it is a reason to check the list.
  • gelatin in the coating · by the listthe list has no ingredient of the “vegetarian coating” group — a plant-based tablet coating instead of gelatin; it keeps moisture out and makes swallowing easier

Solgar Magnesium Citrate 420 mg is magnesium as citrate: 420 mg per serving of 2 tablets. That is 100 % of the adult daily intake, above the upper safe level for supplements (250 mg) — such a dose is taken only on medical advice or split. The form absorbs well and usually does not loosen stools. The formula has 8 ingredients, 1 of which does the work; the rest is coating and fillers. Worth noting: titanium dioxide (color) (white coating pigment; banned as a food additive in the EU since 2022, permitted in Russia and the US). Magnesium helps the nervous system and muscles relax: calmer sleep, fewer night cramps and less irritability when magnesium is low. Per the label, free from gluten, wheat, milk, soy, yeast, sugar, sodium (salt). By the list, no artificial sweeteners, colorants E102/E120/E150, carrageenan, gelatin, soy lecithin, gelatin in the coating. Suitable for: adults. pregnancy, children — ask a doctor. kidney disease — not without a doctor. Use: in the evening or with food. When to expect an effect: sleep and cramps — 1–2 weeks; blood level — 4–6 weeks. Label score — 7.1 out of 10 (for “sleep, stress, cramps” — 71 %; without b6 — magnesium works, but b6 helps retain it in cells; could be added without conflict: vitamin b6; a formula with one main purpose; magnesium: the serving is above the upper level — only on medical advice; debatable ingredient groups: titanium dioxide (e171)). Magnesium from supplements in chronic kidney disease — only with a doctor.
