Got this for my 8 year old daughter who had glandlar fever. We took her up gradually to 1 drops twice a day. Within 4-5 weeks she came out of her slump. Her energy returned, and her dull, pale complexion, and lack of sparkle in her eyes all returned to normal.
My husband and I have also been taking it. We noticed the difference within ourselves too, though we've also been taking NADH, multinutrients and vitamin D with K2 (all from The Finchley Clinic).
