The easiest way to tell if you have a vitamin deficiency is to ask your doctor. Random websites are not medical advice.

vitamin b is water soluble, so all the excess should just come out when you pee, however vitamin b is also used in energy drinks and energy products because it “wakes you up”, so it could very well just be a side affect of this.

if you are unsure however, you should consult your doctor or medical personnel, as it might be something else, and I am not qualified to respond to this, more than the information I’ve read and have no medical training, so it could be something I am unaware of.

take care and how you’ll get it sorted.

This doesn’t pass the smell test. There’s COUNTLESS grifters that will sell you some “natural” way to “cure” whatever ailments you might have. ADHD is medically recognized and most certainly not treated with vitamin B because there’s no literature to back that up as an effective strategy.

If there was double-blind peer-reviewed studies that suggested vitamin B deficiency had any reasonable correlation with ADHD we would already be treating it with supplements that way.

Can I ask where you got this information?

This kind of highlights the difference between correlation and causation.

The root cause of ADHD is not currently fully understood but it’s unlikely that it’s a vitamin B deficiency. People with ADHD also routinely have an iron deficiency in their brains during childhood – which scientists theorize could be a contributing factor – as well as a genetic anomaly, which appears to be hereditary. It’s still not known if either of those things actually causes ADHD. Unfortunately, by the time symptoms are present, the damage is already done.

Taking vitamin B supplements won’t necessarily hurt any but I don’t know that it would help much either, outside of giving you an energy boost.
