This is a really good list. One question on your beetroot powder dose: as I was researching this topic yesterday I learned that beetroot power is only somewhere around 3% nitrates (most companies don’t provide nitrate content, but there’s one from Koyah that claims 31mg of nitrates per gram of powder). So to achieve the recommended dose of 6-12mg/kg of nitrates your beetroot powder dose would need to be closer to 200-400mg/kg.
That would make my dose (72kg) around 14,500mg of powder (about 4 servings of the Bulk Supplements powder). Seems like it might be hard on the gut to try to achieve the minimum effective dose of nitrates using beetroot powder. This is just what I’ve gathered in a day: please let me know if I’ve got something wrong here.
