npub194h76frd3mdsp67fn85kdemcn8m0ur5e6qcflnwwap9q25gwj96qdj4ewx (npub194h…4ewx) I used one for years, but then they seemed to stop working for me. Also made my eyes go a bit funny! Sorry, that didn’t answer your question.
The thing that still works for me is high dose vitamin D and trying to get outside as much as I can.
