1. Watch out for consuming too much of a certain vitamin or mineral. For example, if you focus on super veggies like kale, you'll notice you're getting a lot of Vitamin K. Sometimes you can get too much of a good thing. For men, watch out for possibly overdosing on iron...
Does not appear to be any known toxicity for K1 or K2. Hence no tolerable upper intake level has been set. Synthetic K3 OTOH can be toxic in large amounts. A serving of kale has about 7-8% of an average RDA. As an older male, the amount of iron in kale might represent a higher % but I'm not sweating it.
