Fatigue that doesnt lift with a full nights sleep Tingling, numbness, or a pins-and-needles feeling in the hands or feet A sore, red, or unusually smooth tongue Low mood, irritability, or trouble concentrating Unsteady balance, in more advanced cases Nerve symptoms, especially tingling in the feet, can show up before a blood count looks abnormal, so fatigue alone can miss the picture

Only one Phase I clinical trial has been registered, and no Phase 2 or 3 trials have been completed

Unlike oral supplements, which may lose potency during digestion, injections deliver essential nutrients directly into the bloodstream for faster absorption and greater bioavailability
