Magnesium in Black Sugar Protect: What You Can and Cannot Know

Yes. Magnesium is the second of the six ingredients on the brand's ingredient graphic. The amount is not disclosed, and the form is not named.

The form matters. Magnesium comes bound to other compounds, such as citrate, oxide or glycinate, and the label should say which. The brand graphic shows only the word "MAGNESIUM" beside a stock photo of capsules and powder. The sales page text never names it (Black Sugar Protect sales page).

A real label has to list it. FDA rules say nutrients with a daily value, such as chromium, must be listed on their own line with an amount, even inside a blend (FDA, Labeling guide). Magnesium falls in that group. See every missing line on the label check page, or compare all six on the ingredients page.

Adult men need about 400 to 420 mg a day and adult women about 310 to 320 mg, counting food and supplements together. Supplements on their own should stay at or below 350 mg a day (NIH ODS, Magnesium).

The 350 mg figure is an upper limit, not a goal. NCCIH gives the same ceiling for adults unless a provider advises more (NCCIH, Diabetes and supplements). Food magnesium does not count toward it.

The evidence is thin. Trials of magnesium supplements in people with diabetes are few, small and conflicting, and the NIH notes that the ADA finds too little evidence to recommend it for blood sugar (NIH ODS, Magnesium).

The ADA's 2026 Standards name magnesium directly. They say micronutrient supplements such as magnesium or chromium are not recommended for blood sugar benefit. They add that without an underlying deficiency, there is no benefit from mineral supplements for people with diabetes (ADA, Standards of Care 2026).
