There are indeed side effects associated with a vitamin B complex. Possible side effects include dizziness, frequent urination, change in the colour of the urine, black stools, constipation, diarrhea, abdominal pain, nausea, vomiting, redness of the skin and itching.

Strictly speaking, brain fog is not a medical condition itself, but rather a symptom of other medical conditions. It is essentially a type of cognitive dysfunction involving memory problems, lack of mental clarity, poor concentration and/or inability to focus. “Brain fog” can make you feel like you are sleepwalking through life. People with this symptom often report feeling tired, difficulty focusing, forgetfulness, or have hazy thought processes. With brain fog, even simple tasks can become a challenge. When you can’t concentrate, mental tasks can feel like a moving target.
