Vitamin D Deficiency Symptoms in Men

Recently, my friend’s dad was suffering from a very bad pain in his bones, and was having a problem maintaining his usual posture. After a lot of self/home remedies, he decided to consult his doctor. A couple of days later, it was discovered that the pain had nothing to do with cramps or muscle pulls, but that he actually had a severe B12 deficiency of vitamin D. The vitamin D levels in his blood had indeed dropped to a considerable low. Surprisingly, he had experienced most of the Vitamin D deficiency symptoms in men, but the lack of awareness backfired. It is thus, very important that we know more about these Symptoms of b12 deficiency in men, and human beings in general.
