This is very:thinker: strange.
Lead based solder has been used for decades without any 'health supplements' being needed. Unless you eat it, there is virtually no danger from the short term exposure to lead based solder by inhalation or skin contact. I worked all day beside soldering machines with constant fountains of flux, solder and solvents within touching distance and even after months of close proximity, blood tests showed no signs of contamination.
Solder has almost no smell at all, it is not voltaile and essentially a solid at room temperature. It is also not normal for any health supplements to be needed when using it. I suspect you have fallen foul of a scammer who is selling you fake medications on the grounds that the solder puts your health at risk. Whatever makes the smell is not the solder, it may be the 'medications' or the packaging but Pb/Sn solder is virtually odorless.
The reason Lead was reduced or removed from solder is not for immediate health reasons, it was because of the problems of disposing of soldered equipment when it was discarded in landfill. There, the lead would corrode in damp environmental conditions and could eventually pollute the ground although I've never heard of any instances of that actually happening.
