✅ Food Grade / Food Supplement Notice: Tri-Potassium Citrate Powder is supplied as a food-grade ingredient (E332ii) and food supplement. It is not a medicine and is not intended to diagnose, treat, cure or prevent any disease. Food supplements should not replace a varied, balanced diet and healthy lifestyle.
⚠️ Do not exceed 3700mg elemental potassium daily from all sources (food + supplements) without medical supervision.
Consult your GP before use if you:
- Have kidney (renal) impairment — high potassium (hyperkalaemia) is dangerous and potentially fatal in renal disease
- Are taking ACE inhibitors (e.g. ramipril, lisinopril) or ARBs — these raise potassium levels and combination with supplemental potassium increases hyperkalaemia risk
- Are taking potassium-sparing diuretics (e.g. spironolactone, amiloride, triamterene) — serious interaction risk
- Are taking digoxin or other cardiac glycosides — potassium levels directly affect digoxin toxicity
- Are taking NSAIDs (e.g. ibuprofen, naproxen) regularly — NSAIDs can raise potassium levels, increasing interaction risk when combined with supplemental potassium
- Are taking aluminium-containing antacids — citrate enhances aluminium absorption and should not be combined
- Are pregnant or breastfeeding — consult GP before supplementing potassium
- Have Addison's disease, heart failure or any condition affecting potassium regulation
This is not an exhaustive list. If you are on any prescription medication, always consult your GP or pharmacist before adding any supplement.

Key Features at a Glance
What Is Tri-Potassium Citrate Powder?
Tri-Potassium Citrate Monohydrate (E332ii) is the monohydrated tripotassium salt of citric acid — one of the most widely used food-grade potassium sources available. Chemical name: tripotassium salt of 2-hydroxy-1,2,3-propanetricarboxylic acid. Molecular formula C₆H₅O₇K₃·H₂O. Molecular weight 324.42 g/mol. EC/EINECS number 212-755-5. Our potassium citrate powder meets BP (British Pharmacopoeia) and EU Regulation 231/2012 standards and carries E number E332(ii).
Potassium is an essential mineral electrolyte involved in fluid balance, nerve impulse transmission, muscle contraction and maintaining normal blood pressure. Potassium contributes to normal muscle function and normal functioning of the nervous system — both authorised EU/UK health claims. As a citrate salt, potassium citrate is well absorbed and has an alkalising effect in the body, making it a preferred form for dietary supplementation over less bioavailable salts such as potassium chloride.
