eli5 Why do Potassium supplements only have 2% of the recommended daily value? (US)

564 views

In the US, potassium supplements are restricted to no more that 99 mg, or roughly 2% of the recommended daily value. Is there a point to such a low dosage? Is it okay to take more than 99 mg in supplement form?

Potassium RDA is 5g a day. That’s some 10 large tablets if taken on its own. If taken in such quantity it could cause problems in the stomach, where it reacts with acids.

You can buy salt which had some of its Sodium Chloride replaced with Potassium Chloride. Something like [this](https://www.tesco.com/groceries/en-GB/products/260298744). Potassium Chloride tastes different than normal salt, but if mixed in lower proportions it can be used just like normal table salt. That’s what I do, at least.
