What Is Thiamine (Vitamin B1) & Why Is It Important To Diabetics

Thiamine, also known as Vitamin B1, is an essential vitamin. It plays a critical role in the functioning of the body and is especially important for your brain and nerves. Thiamine deficiency can lead to serious health problems and even death if not treated promptly. For this reason, diabetics need to be aware of how thiamine works in their bodies and what symptoms indicate they may be at risk for developing a lack of this vitamin.

What is Thiamine?

Thiamine is a water-soluble vitamin that plays several critical roles in your body. It's also known as vitamin B1, and its proper function helps convert food into energy in your body. Thiamine is found in many foods, such as whole grains, legumes, and meat.

Thiamine and Diabetes

Thiamine deficiency is common in people with diabetes and can cause several health problems. Diabetes can cause thiamine deficiency because of poor nutrition, the side effects of some medications, and other issues. Because thiamine plays an essential role in blood glucose control, people with diabetes need to get enough thiamine daily.

The recommended daily allowance (RDA) for thiamine and other B vitamins is 1.2 milligrams per day for men older than 19 years old and 1 milligram per day for women older than 19. If you have diabetes or are at an increased risk of getting type 2 diabetes, you may need even more thiamine than this every day.

Health Benefits of Thiamine

Thiamine is an essential nutrient for the body. It's part of the vitamin B complex family and helps fuel your brain, nervous system, muscles, and red blood cells. Thiamine deficiency can lead to several health problems if left untreated.

The following are some of the thiamine's benefits:

Thiamine Deficiency

There's no need to worry about thiamine deficiency in most people with diabetes. It is rare and usually only occurs if you have a severe case of malnutrition or are undergoing alcohol withdrawal. However, if you have been diagnosed with diabetes and are struggling to maintain control over your blood sugar levels, there's a chance that you could develop a thiamine deficiency. This is because eating healthy foods rich in vitamins (and other nutrients) can help ensure that your body has enough energy stores for its daily functions.

Thiamine deficiencies occur more frequently among people with diabetes than in the general population. They often take the form of peripheral neuropathy or Wernicke's encephalopathy—two conditions that cause nerve damage or brain damage, respectively—but they can also cause other conditions such as heart failure or Korsakoff syndrome (memory loss).

Diagnosing Thiamine Deficiency

There are three ways to diagnose a thiamine deficiency. The first is to measure the level of thiamine in a person's blood, which can be done through a routine blood test.

The second way is to measure the level of thiamine in their urine. Normal levels should be around 0.5 micromoles per liter (mcg/L), but if that number falls below 0.3 mcg/L, it could indicate a thiamine deficiency and needs to be addressed immediately because it could lead to serious health consequences later on down the road if left untreated or unrecognized for too long after symptoms appear for the first time before diagnosis has been made correctly by taking notice of how many other people were diagnosed with this condition first before making sure they were able to get treated successfully so they don't end up dying prematurely due having such high levels of glucose present within their bloodstreams which caused them not being ableto tolerate eating food anymore without feeling nauseous due having low energy levels becoming exhausted quickly when engaging in activities like exercising or performing household chores as well as sleeping longer than usual hours at night while feeling tired during daytime hours when trying unsuccessfully getting up early enough every morning without having enough rest during night time hours leading up into days where they feel highly exhausted but still need go work regardless since they wouldn't think twice about quitting job if possible given its importance within society since everyone needs money coming back home after spending day working outside house doing various activities such as running errands or picking up groceries shopping groceries at stores nearby instead buying prepackaged ones then eating lunch prepared meals instead frozen dinners cooked beforehand due needing less preparation time required throughout afternoon hours upon getting home before going bedtime then waking next morning ready start new day again!

Sources of Thiamine

Thiamine is found in many foods, including liver, fish, pork, and other meats. It's also present in sunflower seeds, whole grains, and legumes. In addition to these sources, nuts are also a good source of thiamine.

People with diabetes should not overeat vitamin B1-rich food as it can increase blood sugar levels.

If you're diabetic and already at greater risk for thiamine deficiency, you can't afford to be deficient in thiamine

If you're a diabetic and already at greater risk for thiamine deficiency, you can't afford to be deficient in thiamine. Thiamine deficiency is a real problem that many people don't realize they have until it's too late. Diabetes can lead to thiamine deficiency, which you need to keep tabs on if you have diabetes.

The most severe consequence of thiamine deficiency is heart disease. If your body doesn't get enough vitamin B1 (thiamine), your ability to metabolize carbohydrates will be impaired, leading to heart disease or stroke.[3] Other serious health problems related to an inadequate intake of B1 include nerve damage and other conditions associated with poor circulation, such as osteoarthritis or peripheral vascular disease.


By now, you should have a good understanding of the health benefits of thiamine and how it can help diabetics better control their blood sugar levels. If you're diabetic and already at greater risk for thiamine deficiency, you can't afford to be deficient in this vitamin. Ensuring that your diet and lifestyle have enough sources of thiamine is essential for keeping your diabetes under control.
