Vitamin B 12

I would like to take a B complex vitamin to see if it helps my energy level and fatigue but I feel b12 gives me anxiety, which I already struggle from. Any suggestions?

    I would try to find a B complex with the lowest dose of these nutrients. If you can find a B50 (I think Jamieson makes one) that would be ideal.

    To increase your energy levels, also be sure to look at:

    • sleep quantity and quality
    • meal balance (protein + complex carb + fruit/veg)
    • stress levels
    • stress coping activities (including activity)

    Nutrient deficiencies can certainly worsen cognitive processes, including anxiety. I would be mindful of B3 (niacin) which can cause facial flushing (mimicking anxiety symptoms) if taken at a high dose.

    Best of luck!
