✅ Food Supplement Notice: Potassium Citrate Pro 900mg Capsules are a food supplement — not a medicine. Not intended to diagnose, treat, cure or prevent any disease. Food supplements should not replace a varied, balanced diet and healthy lifestyle.
⚠️ Drug Interactions — Consult Your GP Before Use If You Are Taking:
- ACE inhibitors (e.g. ramipril, lisinopril) or ARBs — raise potassium levels, serious interaction risk
- Potassium-sparing diuretics (e.g. spironolactone, amiloride) — hyperkalaemia risk
- Digoxin or other cardiac glycosides — potassium levels directly affect digoxin toxicity
- NSAIDs (e.g. ibuprofen, naproxen) regularly — can raise potassium levels further
- Aluminium-containing antacids — citrate enhances aluminium absorption
⚠️ Also consult your GP if you have kidney (renal) impairment, Addison's disease, heart failure, are pregnant or breastfeeding, or are under 18. Do not exceed 3700mg elemental potassium daily from all sources without medical supervision.

Key Features at a Glance
What Is Potassium Citrate Pro 900mg?
Potassium Citrate Pro 900mg Capsules are the high-strength option in the Charge Products potassium citrate range — delivering 900mg of Tri-Potassium Citrate Monohydrate (E332ii) per vegan HPMC capsule. This provides approximately 322mg elemental potassium per capsule — meaningfully above the 300mg threshold required for all three authorised EU/UK potassium health claims to apply, including the claim for maintenance of normal blood pressure.
The material quality is exceptional. Our Tri-Potassium Citrate Monohydrate is pharmaceutical-grade — a white, granular crystal material with a characteristic texture similar to fine sugar crystals. It meets ≥99.0% assay on anhydrous basis, conforms to BP and EU Regulation 231/2012 standards and carries E number E332(ii). Molecular formula C₆H₅O₇K₃·H₂O. Molecular weight 324.42 g/mol.
Every capsule contains 900mg potassium citrate and nothing else — no bulking agents, no magnesium stearate, no silicon dioxide, no anti-caking agents. Zero fillers. Vegan HPMC capsule shell. In-house encapsulated at our 5 Star FSA-rated facility in Southend-on-Sea, Essex. Food supplement — not a medicine.
Most UK competitors offer potassium citrate at 500mg per capsule — requiring 2 capsules to exceed the 300mg elemental potassium threshold for authorised claims. At 900mg per capsule, Potassium Citrate Pro reaches that threshold in a single capsule, making it a more convenient and dose-efficient option for those seeking the claim benefits.

Frequently Asked Questions
Why is it called Pro?
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. Contact chargeproducts.co.uk/pages/contact for trade pricing and MOQ. COA available on request.
How fast is delivery?
Same-day dispatch on orders placed before 3:30pm Monday–Friday. Standard UK delivery 1–3 working days. Free UK delivery available — see threshold on site.
