If you have eczema, you are probably stressed, and maybe a little anxious or depressed. Hopefully you have learnt to manage stress - with mindful breathing - but often it's hard to 'just relax' when your skin is flakey, red and incredibly itchy.
Nearly every new eczema patient I see is stressed, anxious or depressed. Sometimes all three! So it's important to look for underlying nutritional deficiencies as they could be worsening the symptoms.
Each week I am posting information on vitamins and minerals so you can see for yourself how good nutrition can help to manage and alleviate your symptoms.
Vitamin B1 benefits
Vitamin B1 (also known as thiamine), plays a big part in energy production, which occurs after you have consumed carbohydrates and fats in a meal.
Vitamin B1 is important for the correct functioning of many different body functions such as the digestive tract and nervous system. In fact, without vitamin B1 in your diet you could become constipated or anxious.
According to researchers at the University of Maryland Medical Centre, the B-group vitamins, including vitamin B1, work together to support healthy skin, hair, liver and eye function.
Vitamin B1 and liver detoxification of chemicals
This is why I love vitamin B1...
Along with vitamin C and other B vitamins, thiamine (vitamin B1) plays an important part in your liver's ability to detoxify chemicals. Without vitamin B1, and other supporting nutrients, chemicals can build up in your bloodstream and cause sensitivity reactions.
Poor detoxification of chemical will also worsen conditions such as eczema and topical steroid withdrawal as your skin and digestive tract will have an increased chemical load to deal with when your liver is under functioning.
So while vitamin B1 does not directly prevent eczema, supplementing with a combination of vitamin B1 and other liver detoxification nutrients gradually reduces and prevents food chemical intolerances - and this helps to prevent eczema and other skin rashes.
Vitamin B1 and stress
Vitamin B1 is often referred to as an 'anti-stress' vitamin, along with the other B-group vitamins.
Vitamin B1 deficiency signs
Early symptoms of thiamine deficiency include anxiety or depression, muscle weakness, impaired memory and loss of appetite.
Vitamin B1 deficiency can result in a disease called Beri Beri, which includes symptoms such as emotional disturbances, swelling, pain and weakness of the limbs, weight loss, vomiting, swelling of lower legs and irregular heartbeat.
Vitamin B1 is so important that it is routinely added to commercial bread to avoid widespread deficiency in developed countries such as Australia.
Do the following questionnaire to see if you have signs of thiamine deficiency:
Do you experience any of the following on a regular basis or on a reoccurring basis?
Vitamin B1 deficiency signs
Abnormal eye movements
Anxiety and/or depression
Loss of appetite
Muscle loss (atrophy)
Pins and needles or numbness
Diabetes (type 2)
If you answered yes to 3 or more signs you could have a deficiency. Note not all symptoms will be present in the one person. As with all health questionnaire results, also check with your doctor to rule our more serious health problems.

Important notes about B-group vitamins
When taking any kind of B vitamins, keep the following nutrition rules in mind:
- As B-group vitamins are acidic, avoid mega-doses above 15 mg, especially if you have eczema.
- In order to prevent deficiencies of other B vitamins, take vitamin B1 in supplement form along with other B vitamins, not as a single supplement.
