Vitamin B12 is used in the treatment of vitamin B12 deficiency.

Vitamin B12 is a nutrient which the body requires in small amounts to make red blood cells, generate energy, and keep nerve cells healthy.

• Symptoms of Vitamin B12 Deficiency
• Weakness, tiredness, or lightheadedness
• Anemia
• Heart palpitations and shortness of breath
• Pale skin
• A smooth tongue
• Constipation, diarrhea, loss of appetite, or gas 
• Nerve problems like numbness or tingling, muscle weakness, and problems walking
• Vision loss
• Mental problems like depression, memory loss, or behavioral changes 

• Most people can prevent vitamin B12 deficiency by eating enough meat, poultry, seafood, dairy products, and eggs.
• If you don't eat animal products, or you have a medical condition that limits how well your body absorbs nutrients, you can take vitamin B12 in a multivitamin or other supplement and foods fortified with vitamin B12.

• Vitamin E is essential to the normal functioning of the human body. It plays a central role in your immune system and functions as an antioxidant, neutralizing free radicals that damage cells at the genetic level.
• Vitamin E is fat-soluble, meaning that it is dissolved in fat and able to be stored in the liver and fatty tissues of the body.
   

• Vitamin E acts as an antioxidant (i.e., an inhibitor of oxidation processes) in body tissues. It protects unsaturated fats in the body from oxidation by peroxides and other free radicals.  It also acts as an protection of polyunsaturated fatty acids, cell membranes.
• The vitamin is used commercially as an antioxidant to retard the rancidification of fats, especially vegetable oils.
• Vitamin E aids in the transmission of electrical signals between nerve cells (neurons) of the brain and body.
• Vitamin E is integral to eye health, aiding in the self-repair of the retina, cornea, and uvea (the pigmented portion of the eye).
• Vitamin E can aid in scar healing by hydrating the skin, inhibiting collagen production, and reducing inflammation that can lead to tissue damage.
   

Vitamin E supplements rarely cause any harm if taken at the recommended daily dose.
But sometimes lower doses can trigger side effects like

•  nausea,
•  vomiting,
•  stomach pain,
•  diarrhea.
•  Slow down blood clotting

• Vitamin E deficiency is considered rare in the developed world, except in premature babies with low birth weight or in people with rare genetic disorders such as abetalipoproteinemia or ataxia with vitamin E deficiency.
• VitaminE can neither treat nor prevent liver disease but may help slow its progression.
• VitaminE can slow blood clotting and may need to be avoided in people taking blood thinners like Coumadin (warfarin) or Plavix (clopidogrel).
• VitaminE supplements should also be avoided in people with a history of heart attacks, stroke, bleeding disorders, or head and neck cancers.
• VitaminE supplements are presumed to be safe during pregnancy and breastfeeding.
