It is just a simple extract, the taste may be strong because it is a tincture or alcohol/water extract, so it can be taken straight, mixed; with food or on an empty stomach, etc... I see it has 100% harmless and only suggest 1 dropper because doctors suggest we need Iodine daily and at 1 dropper daily the bottle would last a long time. I know some people say they take large doses, etc. and so far I have heard no ill effects at any dose and this is usually true with simple natural extracts. The body will use what it wants and expel the rest. Note also that the extract is the second strongest source for natural potassium.
