Today is day two of vegan and so good so far. I decided to become vegan after watching so many documentaries and my cholesterol is high. My doctor said to lose 30 pounds by Feb and I'll most likely do blood work again.

I have a question about vitamin B12.
I'm not sure how much to take. I have 5000 mcg one from a few months ago because I heard B12 helps lose weight. I don't want to end up taking to much.

Hi Amborora! Congrats on your transition to veganism. I think asking your doctor is the best course of action as far as B12 goes. I personally take 2000 mg daily. Love the gummy vitamins myself. Everyone absorbs B12 differently. It kind of depends on whether your eat citrus with it or not since citrus helps with absorption. I've been vegan for 7 months and only recently started taking B12. I don't know how much research there is on excessive B12 consumption but I did find this:

Symptoms of Too Much B12 Vitamin

Vitamin B12 is an essential vitamin found in dairy products, eggs, meat and fish. Your body needs this vitamin to support the production of DNA, nerves and red blood cells. Not having enough vitamin B12 can cause a number of problems, including incontinence and memory loss.

According to Oregon State University, high levels of vitamin B12 have not been found to be dangerous. Thus, no significant symptoms of too much B12 exist. Any vitamin B12 that cannot be absorbed and used by your body will be excreted in urine. However, to be as safe as possible, you should still take no more than the amount recommended by your doctor.

Thank you! I'll talk to my doctor next time I see him. I saw that soymilk has B12.
I'll get another blood test in Feb.
