This may be a weird question and I did a search on this forum. Found the lunchbox thread but 81 pages,, :LOL OK so I've been a strict vego for nearly 3 years. When I started I made sure I supplemented with heaps of greens, silverbeet, broccoli etc. I guess in the past 6 months I've gotten a bit slack and haven't taken much notice. So here I am at Phillip Island, after the warmup I'm starting to push hard and both my arms fail me. I can hardly move my wrists and both hands are tingling badly. I can hardly pull my hand up to grab the brake lever, it's THAT hard. Could this be a lack of oxygen not carrying through to my hands? I've done a bit of research and it seems that iron is used in the blood to carry oxygen throughout the body. Now as soon as I back off 5 seconds a lap my hands recover in 2 laps and I do the same again. I can keep the pace for around 1 lap only now before my hands give way. Funny thing is it started about 6 months ago very minor and it's been getting worse, I get the same tingling in my hands during the day just at work on the computer. I THINK it's an iron deficiancy so I've just started taking iron tablets. The question I ask is, has anyone on this forum had first hand experience with this?
