Potassium and Taurine: what the published research says

PubMed indexes 8 records that name Potassium and Taurine together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.

Read this first

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Potassium and Taurine. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.

The research

8 studies naming Potassium and Taurine.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Taurine and/or inorganic potassium as dietary osmolyte counter the stress and enhance the growth of GIFT reared in ion imbalanced low saline water.

Food chemistry. Molecular sciences · 2021 · PMID 35415671

“In addition, dietary K+ and taurine modulated antioxidant and metabolic enzyme activities for easing stress and balancing energy requirements. Thus, blending of potassium (0.2 %) and taurine (0.5 %) in the diet appears best to mitigate stress and enhance GIFT growth reared in inland saline water.”

Velselvi et al. · From the abstract

Names both Potassium and Taurine in its title.

Protective effect of taurine against potassium bromate-induced hemoglobin oxidation, oxidative stress, and impairment of antioxidant defense system in blood.

Environmental toxicology · 2016 · PMID 25213677

Animal study

“Administration of taurine, prior to treatment with KBrO3 , resulted in significant attenuation in all these parameters but the administration of taurine alone had no effect. These results show that taurine is effective in mitigating the oxidative insult induced in rat blood by KBrO3 .”

Ahmad et al. · From the abstract

Names both Potassium and Taurine in its title.

Taurine ameliorates potassium bromate-induced kidney damage in rats.

Amino acids · 2013 · PMID 23913267

Human subjects

“Histological studies supported these biochemical results showing extensive renal damage in KBrO3-treated animals and greatly reduced tissue injury in the taurine + KBrO3 group. These results show that taurine is an effective chemoprotectant against bromate-induced renal damage and this amino acid could prove to be useful in attenuating the toxicity of this compound.”

Ahmad et al. · From the abstract

Names both Potassium and Taurine in its title.

Effect of taurine and apical potassium concentration on electrophysiologic parameters of bovine retinal pigment epithelium.

Experimental eye research · 2006 · PMID 16102750

Animal study

“Thereby, taurine uptake into the RPE is reduced probably by a reduction of the activity of the electrogenic Na+/taurine co-transporter of the apical RPE cell membrane. The findings suggest a mechanism whereby the sustained presence of taurine in the interphotoreceptor matrix following exposure to light may protect photoreceptor outer segments from light-induced oxidative stress.”

Hillenkamp et al. · From the abstract

Names both Potassium and Taurine in its title.

Increased potassium, chloride, and taurine conductances in astrocytes during hypoosmotic swelling.

Glia · 1997 · PMID 9215734

Animal study

“The chloride conductance pathway is activated at a significantly lower degree of hypoosmotic exposure than that which activates the potassium pathway and may be permeable to anionic taurine. These conductance pathways may mediate diffusive loss of potassium, chloride, and taurine from these cells during volume regulation following hypoosmotic swelling.”

Olson et al. · From the abstract

Names both Potassium and Taurine in its title.

Taurine depletion and cardiovascular disease in adult cats fed a potassium-depleted acidified diet.

American journal of veterinary research · 1992 · PMID 1534475

Animal study

“Plasma taurine concentrations were lowest in 3 cats that died of cardiovascular disease in the group receiving potassium-deficient, acidified diets. These data indicated an association between taurine and potassium balance in cats and suggested that development of taurine depletion and cardiovascular disease may be linked to concurrent potassium depletion.”

Dow et al. · From the abstract

Names both Potassium and Taurine in its title.

Similar properties of taurine release induced by potassium and hyposmolarity in the rat retina.

Experimental eye research · 1991 · PMID 1936171

Animal study

“Total inhibition of the K(+)-evoked release was observed at 200 microM DIDS or 1 mM quinidine, whereas the drugs inhibited the hyposmolarity-evoked release by 50 and 68% respectively, at these concentrations. It is suggested that swelling is the signal for the K(+)-induced taurine release from rat retina.”

MorĂ¡n et al. · From the abstract

Names both Potassium and Taurine in its title.

Potassium-stimulated release of [3H]taurine from cultured GABAergic and glutamatergic neurons.

Journal of neurochemistry · 1989 · PMID 2769270

Animal study

“Taurine release was unaffected by omission of calcium, but it was abolished in a low-chloride medium. These results suggest that taurine is released from cells handling other neuroactive amino acids as neurotransmitters.(ABSTRACT TRUNCATED AT 250 WORDS)”

Schousboe et al. · From the abstract

Names both Potassium and Taurine in its title.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Potassium, Taurine, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
