Product analysis
Magnesium Caps 400 mg offers focused support for normal muscle, energy and bone functions when magnesium intake is low. The undisclosed proportions of its magnesium forms make the blend harder to compare for absorption.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality30
The mix includes citrate and aspartate alongside the less favored oxide form. Without proportions, the blend does not establish an absorption advantage.
Ingredient Transparency80
The magnesium amount and forms are stated. The proportions of the different forms are omitted, so the precise blend is unclear.
Value For Money48
The magnesium mix offers middling value for the serving cost. Undisclosed proportions limit how confidently the more favorable forms can justify the price.
Customer Satisfaction94
Customer feedback is highly positive across a very large number of ratings. The broad response count gives substantial context for satisfaction.
Product Focus72
The clearest benefits are filling a magnesium gap and supporting normal muscle, bone and energy functions. Broader stress, fitness and cardiovascular effects remain uncertain or inconsistent.
