Mary Ruth Organics Elderberry Liquid Drops$20 Why you need it: Perfect for kids or if you prefer a sweeter immunity supplement. Why we love it: I have tried everything over the years to get my kids to take supplements. You would think they would like, the elderberry syrup, but its too much; gummies have too much sugar. But these drops are perfect its just a few drops its quick, and easy, to take. I add it to my immunity rotation during winter or when traveling.
