Is low B12 getting on your nerves?

Monday, August 19, 2019
If there is one group of vitamins that are essential for nervous system support, it is B vitamins. Yet these water-soluble vitamins can be easily flushed away or destroyed by things like heat or alcohol, leaving you feeling jumpy and irritable.

Vitamin B12 is one of the hardest of the B vitamins to maintain, especially for those people who do not eat animal products, as these are the easiest sources to obtain it from. However, even if you are consuming foods rich vitamin B12, the next issue is absorption.

A healthy digestive system is required to assimilate B12. Sufficient stomach acid is needed to break down B12 from the food you eat, and healthy amounts of a chemical “intrinsic factor” are needed to allow absorption through your gut. Both stomach acidity and intrinsic factor can decline with age, which is why you may find yourself low in B12 as you get older.

B12 insulation

The way vitamin B12 works to support your nervous system is by helping to create the insulating material that surrounds your nerves, so they can send their electrical messages more effectively. This works like the plastic coating around electrical wires. Low B12 can affect these coatings – so maybe the expression ‘your nerves are frayed’ could have a new meaning.

Your nervous system is the master communication network in your body, and it uses electrical signals. You need it to gather information about the outside world; it helps to interpret what you experience and how you respond.

Fight or flight?

Your nervous system also governs whether you are in rest and digest mode or when you are in fight or flight mode. Therefore, when you have prolonged periods of stress it can tax the nervous system leading to a greater need for B vitamin support.

Also, when you consider that stress can affect your digestive system and absorption capability (which can lead to low B12) you could be in further trouble. Especially as vitamin B12 is so important for maintaining healthy sleep patterns – it is known to help regulate the sleep-wake cycles.

Help frayed nerves

Clinicians Vitamin B12 Oral Drops could be an option at times of stress and low energy as it provides 50mcg of vitamin B12 in the form of methylcobalamin. This active form of B12 is immediately usable by the body. As the drops are sublingual, the B12 is absorbed through the mouth to avoid absorption issues via the digestive system.
