Uses for Thiamilate

Vitamins are substances that your body needs for growth and health. You only need them in small amounts, and they usually come from the foods you eat. Thiamine (vitamin B 1) is important for breaking down carbohydrates.

Certain conditions may increase your need for thiamine, such as:

  • Alcoholism
  • Burns
  • Diarrhea (ongoing)
  • Fever (ongoing)
  • Illness (ongoing)
  • Intestinal disease
  • Liver disease
  • Overactive thyroid
  • Stress (ongoing)
  • Surgical removal of stomach

Additionally, the following groups of people might have low thiamine levels:

  • Patients using an artificial kidney (on hemodialysis)
  • Individuals who do heavy manual labor daily

Your health care professional should determine if you need more thiamine.

Not getting enough thiamine can lead to a condition called beriberi. Signs of beriberi can include loss of appetite, constipation, muscle weakness, pain or tingling in the arms or legs, and possible swelling in the feet or lower legs. In severe cases, a lack of thiamine may cause mental depression, memory issues, weakness, shortness of breath, and a fast heartbeat. Your health care professional may treat this by prescribing thiamine.

Thiamine may also be used for other conditions as decided by your health care professional.

Claims that thiamine is effective for treating skin issues, chronic diarrhea, tiredness, mental problems, multiple sclerosis, nerve issues, and ulcerative colitis (a disease of the intestines), or as an insect repellent or to boost appetite have not been proven.

Injectable thiamine is given only by or under the supervision of your health care professional. Other forms of thiamine can be obtained without a prescription.

To maintain good health, it is important to eat a balanced and varied diet. Carefully follow any diet plan your health care professional recommends. For your specific dietary vitamin and/or mineral needs, ask your health care professional for a list of suitable foods. If you think you are not getting enough vitamins and/or minerals from your diet, you might consider taking a dietary supplement.

Thiamine is found in various foods, including cereals (whole-grain and enriched), peas, beans, nuts, and meats (especially pork and beef). Some thiamine in foods may be lost during cooking.

Vitamins alone cannot replace a good diet and will not provide energy. Your body also needs other substances found in food, such as protein, minerals, carbohydrates, and fat. Vitamins often cannot function properly without other foods.

The daily amount of thiamine needed is defined in several ways.

  • For U.S.—
  • Recommended Dietary Allowances (RDAs) are the amounts of vitamins and minerals required for adequate nutrition in most healthy individuals. RDAs for a specific nutrient may vary based on a person's age, sex, and physical condition (e.g., pregnancy).
  • Daily Values (DVs) are used on food and dietary supplement labels to show the percent of the recommended daily amount of each nutrient that a serving provides. DV replaces the previous term of United States Recommended Daily Allowances (USRDAs).
  • For Canada—
  • Recommended Nutrient Intakes (RNIs) are used to determine the amounts of vitamins, minerals, and protein necessary for adequate nutrition and to reduce the risk of chronic disease.

Normal daily recommended intakes in milligrams (mg) for thiamine are generally defined as follows:

PersonsU.S. (mg)Canada (mg)
