Vitamin B5 (Pantothenic Acid) vs. Zinc (Elemental Zn)
Comparing 2 standards across 10 specifications. 10 key differences identified.
Comparing:
Vitamin B5 (Pantothenic Acid)
Zinc (Elemental Zn)
Vitamin B5 is an essential water-soluble vitamin required for the synthesis of Coenzyme A (CoA) and acyl carrier protein (ACP), vital in fatty acid synthesis and beta-oxidation. Adequate Intake (AI) is 5.0 mg/day (no Upper Limit established).
Zinc is an essential trace mineral serving as a structural component in over 2,000 transcription factor 'zinc finger' proteins and catalytic cofactor for 300+ enzymes. Adult RDA is 11mg (men) / 8mg (women), with a Tolerable Upper Limit of 40mg/day.

|---|---|---|
|
Nutrient Type
|
Water-Soluble Amide Vitamin | Essential Trace Mineral |

|
Primary Biological Function
|
Coenzyme A (CoA) backbone (Acetyl-CoA, Succinyl-CoA), Acyl Carrier Protein in fatty acid synthase, Steroid hormone synthesis | Zinc finger DNA transcription factors, Superoxide Dismutase (SOD1), Carbonic anhydrase, Testosterone synthesis, Phagocytosis |
|
Deficiency Condition
|
Extremely rare ('Pantothen' = everywhere in foods); 'Burning Feet' syndrome (paresthesia), fatigue | Impaired immunity, Hypogonadism, Delayed wound healing, Alopecia, Loss of taste/smell (Anosmia/Ageusia) |

Copper Balance Warning
|
— | High zinc stimulates intestinal metallothionein which binds copper, risking microcytic anemia if copper is unsupplemented |
