Hello there @bplunn, welcome to the forum, fellow survivor of Myeloproliferative neoplasms ('MPN'). I see we were both diagnosed around 3 years ago, although I live with Polycythaemia vera ('PV') rather than Essential thrombocythemia ('ET').
Perhaps you’d like to read the great Blood Cancer UK information on Essential thrombocythemia ('ET') where you’ll find details about symptoms and typical treatments: Essential thrombocythaemia | Blood Cancer UK
Here’s a thread full of lovely folks living with Essential thrombocythemia ('ET') that may be of interest to see how others are getting on: ET diagnosis finally sinking in
If you’d prefer to read more localised information from Blood Cancer United, the American equivalent to BCUK, here is their website where you’ll find links to a similar forum and information more closely aligned to US healthcare as it’s pretty different in some ways to NHS healthcare in the UK: https://bloodcancerunited.org
I hadn’t heard of the term “neutraceuticals” and it sounds like it typically relates to marketing in the US for what Brits might call complementary healthcare. We forum members can’t recommend treatments, complementary or otherwise, as that’s for our specialists to help us decide, but I’d say it’s great that you’re so active. Keeping active is shown and recommended by specialists to really help us offset the fatigue that is so common with Myeloproliferative neoplasms ('MPN') and other cancers.
I would say that it’s always wise to pass any change in diet or supplements by our haematologists. I speak from experience as I used to take a multivitamin that actually worsened my Polycythaemia vera ('PV') symptoms due to its iron content. It probably prolonged my need for phlebotomy and maybe even put me at higher risk of clotting, which I’m sure you know is our main risk with Myeloproliferative neoplasms ('MPN').
I wonder what your specialists say about taking those supplements, they’d likely want to know so they can adjust your treatments to help bring down those high platelets. For what it’s worth, I’m also in the US (in California) and take daily hydroxyurea and aspirin which have brought my blood cell numbers down into their normal ranges. Personally, the benefits for me of taking hydroxyurea and living into old age far outweigh its potential risks. I wonder why you don’t mind taking aspirin but not hydroxyurea, maybe something to consider.
Anyway, hope that helps you find what you need on the forum @bplunn, glad you found us!
