A person in one of my groups reported that their doctor prescribed them injections of 1mg of Methyl B12 for sensory issues related to their Asperger's Syndrome. Out of curiosity I looked it up and see there are tons of articles and studies promoting the use of Methyl B12 to treat the symptoms of Autism and SPD. Methyl B12 for general use reports promoting better sleep cycles, digestion, lifting brain fog, brain and nerve health, and partnered with Folic Acid reduces levels of homocysteine.
I am not a doctor nor am I advising anyone to try this, but upon further research and out of desperation to lessen my own sensory issues, I have decided to try it for myself. Most doctors advise taking an intramuscular injection or nasal spray, but over the counter sublingual form is acceptable. Pills that you swallow do not work as well since you must have a healthy gut to be able to digest and absorb them properly.
The US National Library of Medicine reports that a study on the effect of Methyl B12 on children with Autism suggests it is ineffective on treating behavioral symptoms but may alleviate symptoms of Autism possibly by reducing oxidative stress.
The most common side effects are: sensory overload, poor or disrupted sleep, hyperactivity, increased stimming, and mouthing of objects. Many articles suggest lowering the dose if side effects should occur.
Consistent delivery should be given the first five weeks and to achieve maximum effectiveness, 18-24 months.
I've found Methyl B12 is not that cheap and is not the same as B12 - it must say Methyl or Methylcobalamin. However almost all grocery and drug stores in my area carry the micro lozenges. I was able to pick up a bottle of 90 5,000mcg micro lozenges at CVS with a manufacturers coupon and a sale for only $9, but it is normally priced $18 and change. I also ordered some at 10,000mcg that are also vegan and gluten-free from IHerb.com. *If you are a new customer use coupon code MOD625 to get $5 off your first purchase or $10 off your purchase over $40! Right now IHerb has a trial in which you can try a bottle of 30 5,000mcg Methyl B12 tablets for only .50 cents!
It is widely known that people who follow a strict Vegetarian diet are deficient in B12, and as a long time Vegetarian who is very picky and refuses to eat many things, it probably can't hurt me to try it. I will post any observations or side effects.
