Angiotensin II Receptor Blockers (ARBs) can increase potassium levels, while sea moss is high in potassium; combined use may increase hyperkalemia risk, especially in patients with reduced kidney function.

Full write-up
What is it
Angiotensin II Receptor Blockers (ARBs) are cardiovascular medicines in the antihypertensives family. This class includes Losartan, Valsartan, Irbesartan, Olmesartan, Candesartan, and Telmisartan.
This page is an educational reference for considering interaction questions involving these medicines and other products someone may be taking, including Beetroot Extract, Iodine, Potassium, and Sea Moss (Irish Moss). It is not medical advice; anyone with a medical condition can consult a clinician about their individual situation.
What interacts with it
The main concern with Angiotensin II Receptor Blockers (ARBs) is increased potassium. ARBs reduce potassium excretion by blocking angiotensin II effects on aldosterone release. Adding Potassium can therefore raise potassium levels substantially, with the possibility of hyperkalemia and potentially fatal arrhythmias. Beetroot Extract and Sea Moss (Irish Moss) are also high in potassium, so combining either with an ARB may further increase this risk. The concern is greater for people with reduced kidney function or other factors that retain potassium.
High-dose potassium iodide or concentrated Iodine preparations may also contribute to hyperkalemia, while ARBs can increase this risk further. This combination warrants particular caution in people with renal impairment or those using other potassium-retaining therapies.
These interactions are described in pharmacology references. Anyone considering one of these supplements while taking an ARB can discuss the combination with a prescriber or pharmacist, who can consider kidney function, other treatments, and whether monitoring is appropriate.
