I have heard friends talk about taking various homemade elderberry products to prevent them from getting sick or recover from illness, and to be honest, that just seemed like an effort I wasn't willing to do. So I was happy to try these gummies, which seems to give you that same benefit in an easier package. The label says that 2 gummies per serving gives you 150mg of Elderberry Extract, 100mg Vitamin C, and 10mg of Zinc. I've been trying them for a few days now as a supplement. I have no idea if they are "working," but they have a good flavor and texture and are an easy way to get added immune support, so I'd definitely recommend them to someone who is looking for a supplement like that. They are vegan, and although I don't see a gluten free label, they do not appear to have gluten ingredients.
