For your vitality and well-being, we will always place an emphasis on ingredient and formulation quality. SHIELD is crafted with the purest botanicals and herbs available. SHIELD was researched and developed extensively for maximum immune support and is a complete immune modulation and immune wellness supplement. There is not another immune support supplement on the market that compares to SHIELD in the number of quality, immune-supporting ingredients that are in our formula. Additionally, while most CBG products on the market are made from distillate or oil, SHIELD uses an isolate form of CBG—which is the purest, most expensive form of CBG to produce.
