Introduction
Thiamine Hydrochloride tablets are vitamin tablets (Vitamin B1); you will have been given these because your body does not have enough Thiamine (Vitamin B1).
What is Thiamine Hydrochloride and why do I need it?
Thiamine hydrochloride is a synthetic version of natural Thiamine (vitamin B1); this will help to increase the Thiamine levels in your body that your diet alone cannot provide. Your body does not produce Thiamine naturally, so a varied diet is essential. Thiamine (Vitamin B1) is an important nutrient for taking energy from food and turning it into energy for your brain, nerves, and heart. When your Thiamine levels are low, this can lead to deficiency and can cause ongoing and lasting health issues.
What happens if my Thiamine levels are low?
Your body stores very little Thiamine, so Thiamine deficiency can happen very quickly, especially if you are not eating very much. Certain conditions can cause lack of Thiamine re-absorption, i.e., Alcohol Excess, Diabetes, HIV/AIDS, Bariatric surgery, anorexia nervosa, Hyperemesis Gravidarum (pregnancy-related sickness), ongoing nausea/vomiting, and advanced age. Sometimes your diet alone cannot provide your body with enough, and Thiamine tablets will be recommended by your healthcare provider.
What happens if I don’t have enough Thiamine?
As mentioned, your body stores very little Thiamine; if you are not eating much or if you are vomiting for any reason, this can deplete your levels further. Not having enough Thiamine from your diet alone can cause serious health complications.
What are the symptoms of Thiamine Deficiency?
- Blurred or double vision
- Facial weakness
- Memory loss
- Rapid heartbeat
- Dizziness
- Leg swelling
- Numbness to face, hands, and feet
- Loss of balance
- Loss of muscle power
- Struggling to urinate
If Thiamine deficiency is severe, serious health problems can occur. Always consult your healthcare provider.
Where can I get Natural Thiamine?
Thiamine can be found in Thiamine-enriched foods, eating a varied diet including poultry, meat, fish, cereals, beans, fresh vegetables, and some dairy. Some foods can inhibit Thiamine absorption also; these include coffee, chocolate, black tea, and alcohol.
What will be the benefits of taking Thiamine?
Taking Thiamine will help to prevent complications of the nervous system, heart, and brain. Vitamin B1, or Thiamine, enables the body to use carbohydrates and turn them into energy, which is essential for body function. If your healthcare adviser thinks you are at risk of developing Thiamine deficiency, you should be offered Thiamine. Fortunately, Thiamine Deficiency is usually easy to reverse with supplementation.
