Description: <b>Magnesium (Mg²⁺)</b> is an essential divalent cation and enzymatic cofactor involved in >300 biochemical reactions. It is not a phytochemical or drug but a physiological mineral regulating ATP stability, kinase activity, membrane potential, and Ca²⁺ channel function. Its dominant biology ranks as: (1) ATP-dependent enzymatic support and genomic stability, (2) Ca²⁺ antagonism and membrane stabilization, (3) modulation of inflammation and oxidative stress, and (4) indirect effects on insulin signaling and vascular tone. Bioavailability depends on salt form (e.g., citrate > oxide), with serum tightly regulated (~0.7–1.0 mmol/L). In vitro cancer studies often manipulate Mg²⁺ concentrations outside physiologic range, limiting translational relevance. Clinically, magnesium status correlates with metabolic, cardiovascular, and possibly cancer risk, but it is not an established anticancer therapeutic. Effects are systemic-regulatory rather than cytotoxic.<br>

RDA. 51+ years male420 mg. Female 320 mg<br>
Pumpkin seeds (hulled, roasted): 1 oz = 150 mg of magnesium<br>
Peanuts (dry roasted): 1 oz = 49 mg of magnesium.<br>
Shredded wheat (plain, unfrosted): 1 cup = 56 mg of magnesium.<br>
Milk (nonfat): 1 cup = 24 to 27 mg of magnesium<br>
Yogurt (plain, low fat): 8 oz = 42 mg of magnesium.<br>
Dark chocolate (70%-85% cocoa): 1 oz = 64 milligrams of magnesium.<br>
Water saskatoon 19mg/L<br>
<br>
Magnesium acts as a natural calcium antagonist<br>
Magnesium deficiency contributes to an exaggerated response to immune stress and oxidative stress is the consequence of the inflammatory response.<br>
Simultaneously, magnesium ion deficiency, which antagonize calcium ions, increases intracellular calcium overload, activating numerous calcium-dependent kinases and proteins, such as nitric oxide synthase and calcium-dependent calcium-binding proteins, further augmenting ROS production.<br>
<br>
Magnesium (Mg) is an essential mineral that plays a crucial role in various cellular processes, including energy production, DNA synthesis, and cell signaling. <br>
-Mg deficiency has been linked to an increased risk of cancer.<br>
-May theoretically improve Ascorbic Acid (IV) efficacy.<br>
