sounds like a normal reaction of a vegan who suddenly had a load of iron
are you a vegan?
If your body isn't used to it you have to take it moderately the same way they give us IV ;)

its the first time I heard that beet actually can be used to detoxify your liver, I'm taking more of a blend of dandelion, fennel, coriander, turmeric, ginger, anise and cinnamon to do that in a week once a month when I get to splurge eating out with any of my friends

it's also the reason I always take ginger and turmeric there
