Product analysis

76 out of 100

Ultra-Mag offers magnesium and vitamin B6 to help fill nutrient gaps, with some support for sleep quality in adults who sleep poorly. The magnesium sources are named, but their undisclosed proportions make the blend harder to compare.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality73

The magnesium blend includes forms with favorable absorption characteristics, and the B6 form is clearly identified. Undisclosed magnesium proportions prevent a precise judgment of the blend as a whole.

Ingredient Transparency62

All listed amounts are stated, and the main magnesium and B6 forms are named. The proportions of the magnesium sources are undisclosed, limiting detailed comparisons between blends.

Value For Money79

The B6 and magnesium components offer favorable value. Value for the other listed nutrients remains uncertain, so the main advantage concerns those two nutrients.

Customer Satisfaction97

Customer ratings are very positive. The unusually large number of responses gives a broad view of satisfaction.

Product Focus75

The strongest practical fit is filling magnesium and B6 gaps, with qualified support for sleep quality. The many suggested uses have different levels of support, and combining magnesium forms does not establish added benefit.

Magnesium may modestly improve reported sleep quality in some adults with poor sleep. This serving provides 400 mg across several declared forms, but the evidence does not establish that this combination or any particular salt improves sleep more. Vitamin B6 supports normal neurotransmitter metabolism; that normal role does not establish extra sleep benefit from supplementation. The strongest relevant human findings remain limited and reflect repeated use.

Magnesium may support calmer responses when magnesium intake is low. Vitamin B6 contributes to neurotransmitter metabolism, though its individual contribution to stress relief remains difficult to separate from combination findings. The formula connects nutritional and mood-related processes without establishing broad, lasting relief from everyday stress.

Magnesium supplies a qualified connection to blood-vessel function, with inconsistent cardiovascular-marker findings and greater plausibility in low-status or elevated-blood-pressure settings. The selected two-tablet serving provides 400 mg elemental magnesium and meets the saved amount reference; combining several salts does not establish extra cardiovascular benefit. B6 supports homocysteine metabolism and is included in the saved findings, but that role does not establish an independent cardiovascular-event benefit. The serving is not automatically the daily regimen used in studies.

How this product is rated for Cardiovascular Support

Ingredient fit83

Magnesium and B6 both meet their saved amount references. An additional active and multiple linked goals make cardiovascular support a partial focus.
Goal fit
Two ingredients receive inclusion, while another active and several linked goals broaden the product's focus.
Dose adequacy
Magnesium and B6 meet their saved amount references in the selected two-tablet serving.

Pathways80

The saved findings include homocysteine handling through B6 and vascular tone through magnesium. These categories do not establish prevention of cardiovascular events.
Depth
Homocysteine handling reaches full saved coverage, with a substantial vascular-tone contribution.
Breadth
Homocysteine handling and vascular tone reach the saved coverage threshold.

Evidence79

Magnesium leads the saved evidence comparison, and both included ingredients are counted as studied. B6's biochemical role alone does not establish cardiovascular outcome benefits.
Evidence strength
Magnesium supplies the strongest included evidence, below the framework's highest cardiovascular evidence category.
Studied preparation
Magnesium and B6 are counted as studied preparations; multiple magnesium salts do not establish superior cardiovascular efficacy.

Formulation logic100

Both included ingredients clear the saved minimum, with no missing required partner or listed conflict.
Partner coverage
The included ingredients work alone or have their required partners, without establishing extra benefit from the combination.
Conflicts
No conflict covered by the supplied checks was detected.
Effective doses
Magnesium and B6 both clear the saved minimum for inclusion; this threshold is not a guarantee of benefit.
