Little Nemo Nov 2024 1:01pm, 28 Nov 2024 15,921 posts	Quote Pin Little Nemo I must have the same leaflet. I don't drink tea so that's not an issue for me.
Velociraptor Nov 2024 1:04pm, 28 Nov 2024 72,265 posts	Quote Pin Velociraptor Long term, coffee and tea have a weak effect in inhibiting iron absorption, but just having coffee or tea in the few days before donating wouldn't make a critical difference.
Groundhog Nov 2024 1:08pm, 28 Nov 2024 6,672 posts	Quote Pin Groundhog My issue might have been trying to loose weight and dieting and possibly just not having enough veg in the week or so before. Possibly a half marathon as well which were more likely factors.
Velociraptor Nov 2024 2:04pm, 28 Nov 2024 72,268 posts	Quote Pin Velociraptor Very few things you do only in the week or so before a donation short of applying leeches will reduce your haemoglobin. Having a restricted diet for a couple of months might, if it meant eating less iron or vitamin C containing foods
Velociraptor Nov 2024 2:06pm, 28 Nov 2024 72,269 posts	Quote Pin Velociraptor It's the overall picture in the 3-4 months before the donation that matters. And sometimes falling on the wrong side of the test is just bad luck or slow recovery from a previous donation.

Velociraptor Nov 2024 9:44pm, 28 Nov 2024 72,280 posts	Quote Pin Velociraptor It's an anecdotal thing. My n=1 study says that failing the test is no more likely in the week after a long race than at any other time. (Watch me get a three month ban later this month now I've said that )
