As I mentioned, B12 is not a problem for many, many years. So supplementing is more of a preventative thing for the far future haha! Omega 3s from flax seeds aswell, you're going to see that effect only when you get really old. People who have enough omega3s in their diet tend to develop less demention and similar brain disease in old age.

So don't worry, we all can be unresponsible when it comes to our bodies sometimes. Doing that in the long run is what causes major problems.

You're very welcome! :)
