This is my go to allergy supplement. I use it daily and it keeps my allergies at bay year round. I've been using it for a handful of years now. The one for kids works well too if they can tolerate the taste of the chewable. We first started these are a homeopathic Dr recommended. Great product!
This takes a few days for your body to get used to, but when it does it works like a champ. I have been using this product for a few years now and I won't be going back to the over the counter stuff. This was recommended by a holistic doctor and it really helps with sinus headaches and sneezing due to allergies both every day and seasonal.
