Potassium Citrate Pro contains 900mg per capsule — the highest dose in our range. Most UK competitors offer 500mg capsules, which provide ~180mg elemental potassium per capsule — below the 300mg threshold needed for the authorised health claims. At 900mg, one Pro capsule provides ~322mg elemental potassium, clearing the threshold in a single capsule. What are the authorised UK health claims for potassium? Three authorised EU/UK claims apply: (1) Potassium contributes to the maintenance of normal blood pressure; (2) Potassium contributes to normal muscle function; (3) Potassium contributes to normal functioning of the nervous system. These apply at ≥300mg elemental potassium per serving — met by a single 900mg capsule (~322mg elemental K). ⚠️ Are there drug interactions I need to know about? Yes — several important interactions. Consult your GP before taking if on: ACE inhibitors (ramipril, lisinopril), ARBs, potassium-sparing diuretics (spironolactone, amiloride), digoxin, NSAIDs (ibuprofen, naproxen), or aluminium-containing antacids. Also consult your GP if you have kidney impairment, Addison's disease, heart failure, are pregnant or breastfeeding. How much elemental potassium is in each capsule? Each 900mg Tri-Potassium Citrate capsule provides approximately 322mg elemental potassium — around 16% of the 2000mg daily NRV for potassium. This is above the 300mg threshold for all 3 authorised EU/UK potassium health claims. What is the quality of the potassium citrate used? We use pharmaceutical-grade Tri-Potassium Citrate Monohydrate (≥99% assay, BP/EU Regulation 231/2012 standard). The material is a white granular crystal — a fine, sugar-crystal texture indicating exceptional purity. COA available on request. Are there any fillers in the capsules? No — zero fillers, zero binders, zero excipients. 900mg Tri-Potassium Citrate Monohydrate in a vegan HPMC capsule shell. Nothing else. What's the difference between Pro and standard Potassium Citrate Capsules? Pro = 900mg per capsule (~322mg elemental K) · above claim threshold in one capsule. Standard = 500mg per capsule (~180mg elemental K) · two capsules needed to reach claim threshold. Both use the same BP/EU grade material with zero fillers. Choose Pro for single-capsule convenience above the claim threshold. Do you sell potassium citrate capsules wholesale? Yes. Charge Products supplies potassium citrate capsules wholesale UK.
