Hi @nicolaclare
Welcome to the forum. I’m sure a BCN nurse will answer your question soon.
I too have had invasive bi lateral cancer with surgery, chemo, Herceptin continues until September, with Zolendronic acid infusions and Letrozole. I too have many side effects but I have taken supplements orally apart from Calcium and VitaminD that is prescribed.
I have Epsom Salt baths 3 times a week as the magnesium can help with aches. I find I’m in more pain and stiff in the morning, after a car journey or if I don’t move much. So movement helps a lot, I walk and do stretches. I started lifting some light weights but I have sore chest wall pain and nerve problems which could be chemo or radiotherapy related. I’m seeing a physio. I have sage, lemon and honey tea, I have a sage plant in the garden. I also have immune shot as a hot tea. See below.
Memorial Sloan is great for looking up contraindications of herbs with your medication. Dr Liz O’ Riordan recommended it.

I would talk to your team about any herbs or supplements you want to take as you don’t want them to reduce absorption your treatment.
There is also a group for HER2 buddies if you would like to join
Take care
