Is it safe to take potassium bicarbonate?

Potassium bicarbonate increases potassium levels and it may be unsafe to take it along with other products that contain potassium. Having high potassium levels (hyperkalemia) is a health concern and can cause serious symptoms, such as: Anxiety. Diarrhea.

What is potassium sulphate good for?

Potassium sulfate is an excellent source of K nutrition for plants. The K portion of the K₂SO₄ is no different from other common potash fertilizers. However, it also supplies a valuable source of S, which protein synthesis and enzyme function require. Like K, S can also be too deficient for adequate plant growth.
