Ummm... I've been a strict vegetarian for more than three decades now. I was an extreme endurance athlete, consuming in excess of 12,000 calories a day in my 20's with a vegetarian diet. I've never had a B12 or any other vitamin deficiency and the last time I saw a doctor was in my early 40's due to chest pain after a swimming workout which ultimately was the result of over-developed lungs getting caught on my rib-cage. After running numerous tests, the cardiologist was laughing at me when I walked into his office on my follow-up. He said my physical age was in-line with a 20 year old, not a 40 year old and that he'd seen maybe one other person in his years of practice in as good of physical conditioning. It sucks you had a vitamin deficiency but, you can get all the nutrients you need from a vegetarian diet.
