A plant-based diet can power great running, but a few key markers need extra attention. Here is the blood checklist every vegan and vegetarian runner should know.
Plenty of strong runners thrive on a plant-based diet. Done well, it can deliver everything you need to train and race at a high level. The key word is well, because a few specific nutrients need more attention when you cut out meat and dairy, and your blood is the best way to keep track.
B12 is found almost entirely in animal products, so vegan runners need a reliable source such as fortified foods or a supplement. Low B12 reduces healthy red blood cell production, which directly limits how much oxygen you can deliver while running. It is the first marker every plant-based runner should watch.
Plant-based iron is real iron, but the body absorbs it less easily than the iron in meat. That makes ferritin worth tracking closely, especially for female runners. Pairing iron-rich plants with vitamin C helps absorption, and a test tells you whether your stores are keeping up with your mileage.
Zinc is another mineral that is harder to absorb from plant sources. It supports immune function and recovery, both of which matter when you are training hard, so it is worth keeping on your radar.
Vitamin D is not specific to plant-based diets, but it is commonly low in runners generally, and it supports both muscle power and bone strength. Checking it alongside the markers above gives you a complete view of your nutritional foundations.
A plant-based diet and great running go together beautifully when you keep an eye on the few markers that need it. SuperRun's RunBase panel covers iron, B12, and the core nutrients that plant-based runners care about, so you can fuel your way with confidence.
