B- vitamins play a vital role in our health and well-being in our body. Their deficiency can lead to severe problems to our health.
 
If you find that you have the symptoms of deficiency, you can try supplements.
 
I have listed dosage information, possible interactions with other supplements and potential side effects.
 

1-Vitamin B1 or thiamine

  • Thiamine plays an essential role in the normal functioning of the nervous system
  • is necessary for the regulating of carbohydrates and proper digestion
  • It protects heart muscle

  • helps prevent constipation.
You can find B1 in Cereals, nuts, legumes, green leafy vegetables, milk, eggs, banana, and apples.
 
The deficiency can cause:
  • Impairment of the digestive system

A high-quality multivitamin supplement should contain sufficient thiamin, usually as thiamin hydrochloride.

You can also find in a vitamin B-complex supplement, and as an individual nutrient in tablet and capsule form.

Possible side effects

Thiamine is safe when you take the RDI.

But, in 5 mg, can cause side effects such as Itching, flushing, abnormally rapid heartbeat(tachycardia) in sensitive individuals.

Medications such as antibiotics, epileptic drugs, oral contraceptives, and sulfa drugs can decrease thiamin levels in the body.

Thiamine is used as a supplement to treat impaired mental function in the elderly or people with Alzheimer’s disease.

Food sources: Milk and byproducts, eggs, meat, poultry, liver, and other animal products.

Signs of deficiency: It causes anemia, which may be caused by inadequate consumption of B12 or inability to absorb it properly.

It can also be caused by an insufficient amount of stomach acid or abnormal bacterial growth in the intestines.

Other signs include memory loss, nerve damage, decreased reflexes, hallucinations, eye problems, and digestive problems.

Possible interactions: People who take antigout or anticoagulant medication or potassium supplements may have a problem absorbing dietary B12 and need additional supplementation.

B7 or Biotin

Is known also as vitamin H and it is a member of vitamin b family.

B7 functions are:

  • Assist the metabolism of fats, carbohydrates, and proteins
  • help with cell growth and facilitate the utilization of other B vitamins
  • Studies have shown that biotin helps in controlling the insulin-dependent or non-insulin-dependent diabetes.

Some good food sources: Soy, egg yolk, almonds, walnuts, oatmeal, broccoli, bananas, peanuts, liver, kidney, milk, legumes.

Possible interactions: Biotin works with other B vitamins. Substances like antibiotics, saccharin and sulfa drugs can interfere with the bioavailability of biotin.

 

Stress can negatively affect the B-vitamins level. Lots of us are under a lot of stress. Everyday life is filled with stressful events happening at work, at home, without giving us a chance to calm down. Then it shows in our body by lowing energy levels and more.

B- vitamins are water-soluble, and since they dissolve in water, the body cannot store them. So, you need to make sure that every day you are maintaining the normal level b vitamins.

Now, if you find yourself experiencing symptoms or you are aware that you aren’t consuming enough healthy foods, then I recommend taking supplements.
