Historical perspective: Dr. Majid Ali archive

Historical perspective drawn from the authorized writings of Dr. Majid Ali, preserved in the Clarkson archive. Shown for context; it is not current medical guidance.

Magnesium 2014-06-02
Source of the quoted line and of his point that less than 1% of body magnesium is in the blood. His intravenous-trial advice in the same article is not carried.
Magnesium, Potassium, Taurine: the Miracle Nutrient Trio 2018-12-18
His grouping of magnesium with potassium and taurine. Its formulation and disease-reversal passages are not carried; "miracle" is his word.
Integrated Magnesium Therapy 2017-08-03
Cited as historical framing only. The therapy protocol is not carried.
Potassium and Magnesium Contents of Foods 2015-10-31
Background for his food-first emphasis. Food values on this page come from NIH ODS.

Claims we deliberately did not carry

Intravenous and "integrated" magnesium therapy protocols, including an intravenous trial as a test for deficiency.
Clinical procedures outside anything ProperHealth discusses. Experts disagree on testing, and no single method is considered satisfactory.⁵
Magnesium as a treatment for heart disease, cardiac rhythm problems or other conditions.
A treatment claim. For these conditions, taking magnesium supplements is not currently advised.³⁵
That oral magnesium "frequently fails" and deficiency in illness "almost always goes unrecognized".
His clinical observations, not supported by the saved sources. Not carried.
Marketing claims that magnesium supplements improve sleep, calm, anxiety or muscle cramps.
The NIH fact sheets we saved do not assess these uses, so we make no claim either way. "Supports" wording on labels is not pre-approved by FDA.³⁶

Safety wording awaiting sign-off

The 'When to get help now' list is ProperHealth safety wording. Each line cites the official guidance it follows, and those passages are listed above with the other claims. The wording still needs pharmacist sign-off before public use.
