Vitamin b12 is within the recommended range should he continue to take b12 orally? He has been suffering from tinnitus for quite a few years but the condition is worsening and he is finding it intolerable. I would be grateful for any further advice you could give. >> tinnitus is one of those conditions where the symptoms can be deeply disturbing. The continuous or intermittent sensation of a ringing or buzzing in the head typically causes the sufferer to be on edge almost all of the time. Your husband is doing the right thing by getting onto the vitamin b12 in therapeutic dosages, but you are quite right - he will need to double the dosage to 2000mcg daily for a month in order to help repair the myelin sheaths which protect the nerve cells of the inner ear. After this month he can return to gmcg daily until his symptoms recede. So many people are deficient in b12, and tinnitus sufferers in particular tend to be very low in this nutrient. If he hasn’t already, it might be an idea for your husband to check with a specialist in order to rule out any underlying disorders. cheap viagra for sale Do you have a question for megan sheppard?
