In addition to stress-relieving antioxidants and amino acids, Zenify includes 100% of the recommended daily allowance of five important B-vitamins – Vitamins B-3, B-5, B-6, B-9 and B-12. These vitamins are designed to work synergistically with the antioxidants and amino acids in our Zen Blend to reduce stress. Vitamin B-6, for example, serves as a precursor to GABA. Both Vitamins B-6 and B-12 are vital in the production of serotonin. And Zenify also has 500% of the recommended daily allowance of Vitamin C, which has significant antioxidant properties.
