Check the original label ↗Magnesium participates in muscle and nerve function and many enzyme reactions. Products use different salts and chelates, so the total compound weight can look much larger than the magnesium actually supplied. Begin with the elemental magnesium on the panel and the number of tablets or capsules in a serving.
The pack details above come from the manufacturer. Ingredient research below does not establish the effects of this exact product or independently verify its contents.
Three forms, one magnesium total
The 225 mg magnesium total combines bisglycinate chelate (34%), lysinate glycinate chelate (33%) and malate (33%). It is not 225 mg of each. Three capsules make one serving, giving 30 servings in the 90-count bottle.
A small iron contribution is declared
The current panel also declares 1.9 mg naturally occurring iron. Consider that amount when reviewing the whole supplement regimen, rather than treating the product as magnesium alone.
Compare the serving and evidence
The adult directions specify three capsules daily with food. NIH lists a 350 mg adult upper limit for magnesium from supplements and medicines, excluding food magnesium. The manufacturer’s sleep and mood language does not establish treatment results for this particular blend.
Where might it be useful?
Normal muscle and nerve function
Adequate magnesium contributes to normal signalling and muscle activity.
Meeting an intake gap
A suitable supplement can add magnesium when food intake is inadequate or a clinician identifies a need.
What the research can — and cannot — tell us
An essential role in the body does not establish that every form improves sleep, anxiety or cramp symptoms. Differences in tolerability and absorption do not translate into a universal best product. Compare the mineral amount, complete formula and practical serving before making conclusions.
What deserves your attention?
Supplemental magnesium can cause diarrhoea and abdominal cramps. Ask a pharmacist about spacing from antibiotics or bisphosphonates; seek advice with kidney disease, pregnancy or medicines. Count magnesium from other supplements.
Suitability comes before strength
Supplemental magnesium can cause diarrhoea. Kidney impairment can increase risk from magnesium accumulation, and some medicines require separation or review; ask a pharmacist or clinician.
Dietary details for this product
Vegan The current manufacturer identifies the complete product as Certified Vegan. The panel lists a hypromellose/water capsule, microcrystalline cellulose, citric acid, magnesium stearate and silica.
A dietary label and an allergy assessment answer different questions. Check every ingredient, the capsule or softgel materials and the allergen statement on the pack you receive.
