My son asks for Defender Jr every morning!

My son is 2.5 and absolutely loves the Defender Jr. He asks for his "chewable vitamin" every morning. Then he asks for more throughout the day, so they must taste great. I bought them to boost his immunity this winter. He's has minor colds, but seems to get over them pretty quickly so I would say it helping.

Thank you for the 5-star review, Nicole! We love hearing that your son enjoys The Defender Jr. so much — and that it’s become part of his daily routine! It’s wonderful to hear it’s helping support his immunity this winter.

Life saver

I started taking The Defender this fall and it has been a game changer. When I start to feel sick I increase my dose and I swear the next day I wake up feeling back to normal. I also give it to my daughter who is in day care and she has been getting sick much less frequently this fall. Cannot recommend enough (especially if you have day care kiddos).

With 3 kids in daycare, school, and sports I decided to add the Family Immunity to this month’s order. We started feeling sick and took the Immunity and our family didn’t get as sick or have it last as long as the kids other friends. I will continue to use it during this winter.

This stuff is magic!

I hadn't been sick in YEARS and I felt a head cold coming on so I jumped on my Defender bottle and within 2 days started to feel 100% better! Couldn't recommend these pills enough and honestly, the chewable are SO GOOD!!! Run, don't walk.
