This week, we’re talking about micronutrients you want to watch out for. I’m not a herbologist, I’m just looking at what we have for published research related to micronutrients that you may be getting too much of in specific circumstances.

The item for today is actually Vitamin A – and before you all freak out, I’m not telling you to never eat carrots. We are talking about a very specific form of Vitamin A here, specifically, something called a retinal form of Vitamin A. Enjoy!
