  • Absorbed dose vs reference intake0.748 % of the intake per serving; by the absorption curve — 73 % of what the intake would deliver
  • 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 purity1.0No excess doses or debatable ingredients; excipients: 7

Free from:
  • glutenmatters for coeliac disease and gluten intolerance
  • soya common allergen; soy lecithin is often in coatings
  • GMOa buyer's preference; does not affect the safety of the ingredients
  • 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.
  • titanium dioxide (E171) · by the listthe list has no ingredient of the “titanium dioxide (E171)” group — white coating pigment; banned as a food additive in the EU since 2022, permitted in Russia and the US
  • 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

Doctor’s Best High Absorption Magnesium 200 mg is magnesium as bisglycinate (chelate): 200 mg per serving of 2 tablets. That is 48 % of the adult daily intake, within the upper level for supplements (250 mg). 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. 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, soy, GMO. By the list, no artificial sweeteners, colorants E102/E120/E150, carrageenan, gelatin, soy lecithin, titanium dioxide (E171), gelatin in the coating. Suitable for: adults, vegetarians. 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 — 8.5 out of 10 (48 % of the intake per serving; by the absorption curve — 73 % of what the intake would deliver; 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 from supplements in chronic kidney disease — only with a doctor. A 200 mg serving is below the EFSA upper level for supplements (250 mg/day); the label suggests 2 tablets twice daily, which is 400 mg, above it. This restates the norms and the label, not an assessment.
