Potassium Combination provides a modest amount of potassium together with kelp, dulse, alfalfa, horseradish, cabbage and horsetail. Potassium is the key mineral here, and it is commonly used to support fluid balance, nerve signalling and normal muscle function.
The added plant ingredients are there as naturally mineral-rich companions rather than flavour extras. Kelp and dulse are sea vegetables that supply trace minerals, while horsetail and alfalfa are often included in mineral-focused formulas. If you are looking at Potassium Combination, the useful point is that it is a whole-food style blend rather than a high-dose straight potassium tablet.
