While these two vitamins work cohesively to produce energy in cells, vitamin B12 plays an important role in the development and function of vital body parts including the nerve, brain, and blood cells. But surprisingly, these effects of B12 can only take place when the presence of an adequate amount of biotin is ensured. Wanna know how these two vitamins benefit the human body? Continue reading.

What is biotin and what does it do in the body?

Biotin, otherwise known as vitamin B7 or vitamin H, is an important part of the group of B vitamins that help the body metabolize foods and produce energy. It has an important role in assisting enzymes that break down various food substances such as carbohydrates, fats, and amino acids and convert them into fuel which is eventually used to create energy in the boy.  

The human gut can make biotin with the help of certain bacteria but like all other B vitamins, it is water-soluble, meaning the human body cannot store it. For this reason, regular intake of biotin must be ensured. Small amounts are found in certain foods like bananas, eggs, milk, organ meats, nuts, seeds, and certain vegetables. It is also available as a biotin supplement. 

What is vitamin B12 and what does it do in the body? 

Vitamin B12, otherwise known as cobalamin, is also an important part of the group of B vitamins. It plays a critical role in the development and function of many organ systems, particularly the blood, nerves, and brain cells. It’s also crucial for the synthesis of DNA, the genetic substance found in all cells. 

Vitamin B12 is considered an essential nutrient, meaning the human body needs it but cannot make it on its own. Therefore, people must take it through diets or supplements. 

It naturally occurs in certain animal foods such as beef liver, poultry, eggs, milk, and fish. Plant foods usually do not contain this nutrient and hence, vitamin B12 supplements are good options for vegans, vegetarians, or those who otherwise for any reason want to avoid animal foods.    

Biotin vs B12: benefits and uses 

Biotin benefits and uses

Deficiency of biotin is associated with hair loss or thinning of the hair, brittle nails, scaly red rash around the mouth, nose, and eyes, as well as others. Biotin supplements are commonly used to treat the deficiency and its associated symptoms.    

Hair growth, nail and skin issues 

Since low biotin levels are mostly associated with hair, skin, and nail conditions, biotin supplements are commonly used to treat and prevent the thinning of hair, hair loss, brittle nails, and various skin symptoms such as dry scaly skin and rash on the face. 

Biotin, combined with other nutrients such as iron and zinc, is also used to treat alopecia areata in both adults as well as children. 

Other biotin benefits  

Biotin has been found to produce positive effects in the treatment of:

Vitamin B12 benefits and uses 

Megaloblastic anemia, a specific kind of anemia that is characterized by excessive weakness and fatigue, is the hallmark of the deficiency of vitamin B12.

Sleep and brain health 

Vitamin B12 deficiency may lead to disturbed sleep cycles and poor sleep quality. It is crucial for protecting nerve cells in the brain and also plays a vital role in the synthesis of melatonin, a hormone that has a key role in regulating circadian rhythms. This is the main reason why B12 is commonly used to promote sleep and overall brain health, often in combination with melatonin. 

Other B12 benefits 

B12 has been assumed to be helpful in several other conditions as well, including: 

  • Anemia and low levels of red blood cells

  • Alzheimer's disease
  • Increased levels of homocysteine 
  • Cyanide poisoning  

Precautions and side effects 

Both biotin and vitamin B12 are water-soluble and when the human body finds extra of these nutrients it simply passes them through urination. Therefore, there are no risks of toxicity and most people can easily handle these supplements. 

However, some people may experience side effects. Common side effects of biotin include nausea and digestive problems. And common side effects of B12 include headache, fatigue, tingling sensation in hands and feet, and gastrointestinal discomfort. But these are not common. 

Like all supplements, biotin and B12 may interact with certain medications. It’s always best to have a conversation with a certified naturopathic doctor before starting any supplements.
