Here are a few that could potentially cause unpleasant side effects like anxiety.
Vitamin B6
The first of the supplements that could cause anxiety is vitamin B6.
The problem here comes if a formula is unbalanced and provideshigh amounts of B62relative to the other B-vitamins.
Too much vitamin B-6 canincrease the possibility of side effectssuch as restlessness, irritability, and numbness.
Like B6,high doses of B12 increase neurotransmitter levels3, and as a result, have stimulating properties.
Instead, attempt to get your folate from natural sources such as green leafy vegetables and fruits.
