Is sodium in sodium ascorbate dangerous to the kidneys?

Answer 1

No, in fact it may help hypertension.

It is Sodium (Na+ Cation) plus Chloride (Cl- Anion) that can cause hypertension. In studies it has been shown that high dietary sodium chloride increases blood pressure but sodium ascorbate and sodium bicarbonate doesn't. It has also been shown that hypertensive patients have lower ascobate levels (vit C) in their blood than normotensive patients.

Answer 2

Once it goes into solution it doesn't matter where the sodium came from; a sodium ion from sodium ascorbate is indistinguishable from a sodium ion from sodium chloride.

All mineral ascorbates are salts of ascorbic acid (aka vitamin C). They are powders manufactured by reacting ascorbic acid with mineral carbonates in aqueous solutions, venting the carbon dioxide, drying the reaction product, and then milling the dried product to the desired particle size. This would include sodium ascorbate, a very common mineral ascorbate. Relatively large doses of vitamin C may cause indigestion, particularly when taken on an empty stomach, however is generally safe to the kidneys and indeed to the rest of the body even when ingested in substantial amounts.

Answer 3

Sodium ascorbate is generally safe for the kidneys unless consumed in excessive amounts. However, individuals with kidney disorders that require sodium restriction should consult their healthcare provider before taking sodium ascorbate supplements.
