Side-by-Side Comparison
Essential Vitamins & Minerals
Calcium (Elemental Ca) vs. Vitamin B1 (Thiamine)
Comparing 2 standards across 9 specifications. 9 key differences identified.
Comparing:
Calcium (Elemental Ca)
Vitamin B1 (Thiamine)
Calcium is the most abundant mineral in the human body (1.0–1.2 kg), with 99% sequestered in hydroxyapatite bone lattice and 1% tightly regulated at 8.5–10.5 mg/dL serum for cardiac contractility, nerve signaling, and blood coagulation. Adult RDA is 1,000–1,200 mg/day.
Vitamin B1 is a water-soluble pyrimidine/thiazole vitamin acting as the Thiamine Pyrophosphate (TPP) coenzyme in pyruvate dehydrogenase, alpha-ketoglutarate dehydrogenase, and transketolase. Adult RDA is 1.2 mg (men) / 1.1 mg (women) (no Upper Limit established).

Chemical Forms
|
Calcium Carbonate (40% elemental Ca / requires stomach acid), Calcium Citrate (21% elemental Ca / acid-independent), Hydroxyapatite | Thiamine Monophosphate, Thiamine Pyrophosphate (TPP / TDP, active coenzyme), Benfotiamine (Lipid-soluble synthetic) |
|
Primary Biological Function
|
Hydroxyapatite bone/dental structure [Ca10(PO4)6(OH)2], Troponin-C actin-myosin muscle contraction, Factor IV blood clotting cascade, Exocytosis neurotransmitter release | Pyruvate dehydrogenase complex (Links glycolysis to Krebs cycle), Transketolase (Pentose Phosphate Pathway), Myelin neurotransmission |
|
Deficiency Condition
|
Osteoporosis, Osteopenia, Rickets (children), Tetany (Trousseau's and Chvostek's signs of hypocalcemia) | Beriberi (Wet beriberi: high-output heart failure; Dry beriberi: peripheral neuropathy), Wernicke-Korsakoff syndrome |
|
Top Whole Food Sources
|
Parmigiano-Reggiano, Sharp Cheddar, Whole Milk, Sardines with bones, Kale, Tofu (Calcium-set), Fortified Plant Milk | Pork Tenderloin, Sunflower Seeds, Nutritional Yeast, Enriched Grains, Black Beans, Flaxseeds |
|
Parathyroid Hormone (PTH) Homeostasis
|
Serum Ca2+ drop triggers PTH secretion, stimulating renal 1-alpha-hydroxylase to produce active Calcitriol (1,25-OH-D3) and osteoclast bone resorption | — |
|
Thermolability & Alcohol Interaction
|
— | Degraded by alkaline pH and high heat cooking; alcohol blocks intestinal active ThTr-1 transport |
