I've tried and am still using many of the Tennant Products (now for several years). The Restore powder and Raw Materials gives me everything my body needs with better quality materials than anything else out there (I make the restore as a shake every morning). The Brain Food gives me the mental boost I need to power through tough work days. And the Lugol's Iodine has been helping me boost my immune system and feel healthier and whole (pretty important for someone with an autoimmune disorder). The essential oils have also been super helpful in getting good sleep (Sweet Dreams is great for this), and the Soreness essential oil works wonders for sore muscles and aches. Very thankful for these products and definitely recommend! :)
