So I'm sure most of you have seen that dietary nitrates (not the kind from processed meats) improve sports performance if taken before a workout. Arugula, kale, rhubarb and other leafy greens are high in nitrates, the problem is, if I wanted to consume enough nitrates from one of these, I'd have to eat a boat load of fiber before I workout. That is not ideal for me. So I thought, perhaps I will juice and consume the juice 30 min before my workout..... but juicing is so strenuous and requires so much clean up. Also, time wise, I can't always coordinate that. So my question is, does anyone know if I can get nitrates from powdered kale and arugula, like a green powder? Has anyone tried supplementing with these? Are the nitrates preserved through the processing? Please let me know if you know anything about green powders! Thanks!
