CuratedFit
CURATEDFIT SUMMARY
Passes because it is a single-active tablet delivering a clearly stated dose of magnesium, with no proprietary blend and no artificial colors. Magnesium Hydroxide is flagged, not failed, under the CuratedFit Standard's treatment of mineral actives. One synthetic binder is present and flagged, and talc as an anti caking agent is noted as a transparency limitation given known industry purity questions around that ingredient category.
WHAT IT IS
A tablet supplying 375 mg of elemental magnesium (as Magnesium Hydroxide) per two tablet serving, meeting 100% of the Nutrient Reference Value. The manufacturer describes the magnesium as British Pharmacopoeia quality, indicating it meets a recognised pharmaceutical purity standard. The tablet is built around a small number of bulking, coating, and anti caking agents rather than any additional active ingredients.
WHO IT IS FOR
Someone who wants a straightforward, single mineral magnesium supplement at a clearly stated, meaningful dose, rather than a multi ingredient formula bundling magnesium with other minerals or herbal actives.
INGREDIENT BREAKDOWN
Magnesium (as Magnesium Hydroxide)
375 mg, NRV 100%
Magnesium Hydroxide is an industrially manufactured mineral compound, typically produced by reacting seawater or brine with lime. Under the CuratedFit Standard, mineral actives of this kind are flagged rather than failed on natural origin, since they are elemental and functional rather than a biosynthesized active being marketed as a nutritional upgrade.
Other ingredients
Microcrystalline Cellulose, Dibasic Calcium Phosphate, Potato Starch (bulking agents), Hydroxypropylmethylcellulose, Glycerin, Calcium Carbonate (tablet coating and colour), Silicon Dioxide, Stearic Acid, Purified Talc, Magnesium Stearate (anti caking agents), Polyvinylpyrrolidone (binder)
Polyvinylpyrrolidone
A synthetic polymer used as a tablet binder. As a synthetic additive rather than a marketed active ingredient, it is flagged rather than treated as an automatic fail.
Purified Talc
Used as an anti caking agent. Talc as a raw material has attracted industry scrutiny around purity and potential contaminant content, so its presence is noted as a transparency limitation rather than a confirmed issue, since no specific purity or contaminant testing for this ingredient is disclosed on the label.

CURATEDFIT STANDARD CHECK
Warning
As Natural As Possible
Magnesium Hydroxide is an industrially manufactured mineral active. Flagged per the CuratedFit Standard's mineral active precedent, not failed
Info
Contains What It Claims
375 mg per serving is stated clearly on the label. CuratedFit has not seen independent lab verification of this figure
Warning
Every Ingredient Earns Its Place
Polyvinylpyrrolidone is a synthetic binder. Disclosed and functional, flagged rather than failed
Pass
No Insect-Derived Ingredients
No animal or insect derived ingredients present
Pass
No Proprietary Blends
Single active ingredient, no blend to disclose
Pass
Allergen Declaration
Cross contact risk for nuts and peanuts disclosed by manufacturer
Pass
Sugar Content Declared
No sugar present in the ingredient list, tablet format with no added sweeteners
Pass
Artificial Sweeteners and Flavorings
None present. Manufacturer also states no artificial colours
Info
Heavy Metals and Contaminants
Not addressed on the label. Purified Talc's presence is a known category of purity concern in the wider industry, though no product specific testing data is available either way
Pass
Banned Substance Risk Declared
Single mineral, no stimulant or hormonal precursor compounds

TRANSPARENCY NOTE
This is a straightforward, single mineral product, and the main judgment call here is how to treat the magnesium active itself. Under the CuratedFit Standard's mineral precedent, industrially produced mineral actives like Magnesium Hydroxide are flagged rather than failed, distinguishing them from the synthetic Vitamin C case where a biosynthesized vitamin was being marketed as a nutritional benefit while manufactured through non biological means. Magnesium is an element, not a biosynthesized compound, so the same strict natural origin logic does not map cleanly onto it.
The Polyvinylpyrrolidone binder is a similar story to synthetic preservatives seen elsewhere in the catalogue. It is disclosed, it is functional, and it is not marketed as an active benefit, so it is flagged rather than failed.
Purified Talc deserves a specific note. Talc as a raw material has a documented history of purity and contamination concerns in some contexts, most often discussed in relation to cosmetic and industrial applications. This label gives no specific sourcing or testing information for the talc used here, so this is recorded as a transparency limitation rather than a confirmed problem. It does not block evaluating the rest of the formula, but it is worth knowing.
FREQUENTLY ASKED QUESTIONS
Is Magnesium Hydroxide as good as other forms of magnesium, like citrate or glycinate?
Different magnesium forms are associated with different absorption profiles and gastrointestinal tolerance in the research literature. This review evaluates label transparency and ingredient sourcing, not comparative bioavailability between magnesium forms.
Why is the magnesium active flagged rather than passed outright?
Because it is an industrially manufactured mineral compound rather than a biosynthesized ingredient. It is not treated as a fail, since minerals are evaluated differently from synthetic vitamins under the CuratedFit Standard.
Does this contain any proprietary blend?
No. It is a single active ingredient at a clearly stated dose.
Is this suitable for vegans?
Yes, per the manufacturer's stated claim.
Has this been tested for heavy metals or contaminants?
Not that CuratedFit has been able to confirm. No third party testing documentation was available at the time of this review.
What is British Pharmacopoeia quality?
It refers to a recognised pharmaceutical purity standard for the raw ingredient, as reported by the manufacturer.
Where is this product manufactured?
Not explicitly confirmed on the product pages reviewed.
