What Is Biotin and What Does It Do?

Biotin, which is also called vitamin B7, is best recognized for helping keep skin, hair, and nails healthy. But its purpose is much more than just making things look good.

Biotin is a coenzyme that helps break down lipids, proteins, and carbs. This indicates it improves your body:

  • Change food into energy that can be used
  • Keep your nervous system working well
  • Help the body make keratin, which is crucial for hair and nails.

Most individuals get enough biotin from the foods they eat. Eggs, nuts, seeds, and whole grains are all good sources. But using supplements to make hair and nails stronger has grown trendy, even for people who don't need them.

What Is Vitamin B12 and Why Is It Important?

Vitamin B12, sometimes called cobalamin, is important for making red blood cells, DNA, and the nervous system work. It operates in a very different way than biotin and is especially important for brain, mood, and energy wellness.

B12 is good for your health since it:

  • Make red blood cells to deliver oxygen.
  • Protect nerves from injury and keep them healthy
  • Help memory and brain function
  • Stop megaloblastic anemia and tiredness

Animal-based foods, such as meat, dairy, and eggs, mostly contain B12, but not biotin. That's why older people, vegetarians, and vegans are more likely to be low in B12.

Key Differences Between Biotin and B12

Both biotin and B12 are water-soluble B vitamins, but they function differently, originate from distinct food sources, and exhibit different signs of deficiency.

Feature Biotin (B7) Vitamin B12 (Cobalamin)
Main Function Metabolizes fats and carbs, supports skin/hair health Supports nervous system, red blood cell formation
Food Sources Eggs, nuts, whole grains Meat, dairy, fish, eggs
Deficiency Signs Hair thinning, brittle nails, skin rashes Fatigue, memory issues, numbness, anemia
Common Users Beauty-focused supplement users Vegans, vegetarians, older adults
Supplement Form Oral capsules, hair gummies Oral, sublingual, or injections

Biotin and B12 are not the same thing, so don't mix them up or you might treat the wrong problem.

Do You Need Both in Your Routine?

It depends on how you live, what you eat, and how you feel. Unless they are pregnant, using certain medicines, or having trouble absorbing nutrients, most people obtain enough biotin from their food. But B12 is more often missing, notably in:

  • People who don't eat meat and people who do
  • People who are 50 or older
  • People who have low stomach acid or GI problems
  • People who use metformin or drugs that lower acid levels

If you're feeling worn out, forgetful, or have tingling in your nerves, B12 may be what you need. If you're worried about your nails breaking or your hair thinning, biotin might be more helpful. But don't anticipate miracles if your biotin levels are already normal.

Always test before taking any supplements. A blood test can tell you your B12 levels, but it's harder to find out if you lack biotin.

Final Thoughts

People often mix up biotin and vitamin B12, yet they help the body in very different ways. Biotin is good for hair and energy metabolism, but B12 is great for the nervous system, red blood cells, and mental clarity.

You don't have to choose between the two; they can both be part of your health routine. But knowing what each one does best can help you pick the perfect supplement for your needs.

Key Takeaway:
Biotin helps with skin, hair, and metabolism, while B12 helps red blood cells and nerves work. They're not the same, therefore you need to know what your body really requires.
