Essential Vitamins & Minerals
Sodium (Elemental Na) vs. Vitamin E (d-Alpha-Tocopherol)
Comparing 2 standards across 11 specifications. 11 key differences identified.
Comparing:
Sodium (Elemental Na)
Vitamin E (d-Alpha-Tocopherol)
Sodium is the principal extracellular cation (135–145 mEq/L extracellular), maintaining extracellular fluid volume, plasma osmolality, and driving secondary active transport. Adequate Intake (AI) is 1,500 mg/day, with a Chronic Disease Risk Reduction (CDRR) limit of 2,300 mg/day.
Vitamin E is the principal fat-soluble peroxyl radical-scavenging antioxidant protecting cellular polyunsaturated membrane phospholipids. Adult RDA is 15 mg (22.4 IU) of d-alpha-tocopherol, with a Tolerable Upper Limit of 1,000 mg (1,500 IU)/day.

Nutrient Type
|
Essential Macromineral / Major Extracellular Electrolyte | Fat-Soluble Chromanol Lipophilic Vitamin |
|
Chemical Forms
|
Sodium Chloride (NaCl, 39.3% Na by weight), Monosodium Glutamate (MSG, 12.3% Na), Sodium Bicarbonate (27.4% Na) | RRR-alpha-Tocopherol (Natural d-alpha), all-rac-alpha-Tocopherol (Synthetic dl-alpha), Gamma/Delta-Tocopherols |
|
Primary Biological Function
|
Extracellular fluid osmolality maintenance, Blood pressure / volume homeostasis, Action potential depolarization (voltage-gated Na+ channels), SGLT1 glucose cotransport | Breaks lipid peroxidation chain in PUFA cell membranes, protects LDL from oxidative modification, maintains erythrocyte membrane integrity |
|
Deficiency Condition
|
Hyponatremia (Serum Na+ < 135 mmol/L): Cerebral edema, Nausea, Muscle cramps, Seizures, Coma (often exercise-associated from over-hydration) | Hemolytic anemia, Spinocerebellar ataxia, Peripheral neuropathy, Loss of vibratory/proprioceptive sense |
|
Top Whole Food Sources
|
Table Salt (NaCl), Cured Bacon, Soy Sauce, Parmigiano-Reggiano, Pickles, Olives, Bread (Processed food accounts for 70% of intake) | Wheat Germ Oil, Sunflower Seeds, Raw Almonds, Hazelnuts, Sunflower Oil, Spinach, Hass Avocado |
|
Adult Adequate Intake (AI)
|
1,500 mg / day (Equal to 3.8 g table salt NaCl) | — |
|
Chronic Disease Limit (CDRR)
|
2,300 mg / day (Equal to 5.8 g table salt / 1 level teaspoon) | — |
|
Renal Renin-Angiotensin System
|
Juxtaglomerular apparatus senses low tubular sodium/pressure, secreting renin to stimulate aldosterone and renal Na+ reabsorption | — |
|
Adult RDA / RDI
|
— | 15 mg / day (22.4 IU) of 2R-alpha-tocopherol |
|
Tolerable Upper Limit (UL)
|
— | 1,000 mg / day (1,500 IU synthetic) (Excess impairs Vitamin K clotting cascade) |
|
Hepatic Alpha-TTP Specificity
|
— | The liver secretes only alpha-tocopherol into VLDL via Alpha-Tocopherol Transfer Protein (alpha-TTP); other tocopherols are degraded in bile |
