Fully Active B12: boost energy, support nervous and cardiovascular health, improve mood and more

Doctor's Best Fully Active B12 is a dietary supplement that provides vitamin B12 in its active form, methylcobalamin. Vitamin B12 is an essential nutrient that is important for the proper functioning of the nervous system, brain and blood cells. It also helps with DNA production and energy metabolism.

Doctor's Best Fully Active B12 contains 1500 mcg of methylcobalamin per capsule. This form of B12 is considered to be more bioavailable and effective longer in the body than other forms of vitamin B12. It is also involved in the metabolism of homocysteine, an amino acid that can cause damage to blood vessels when present in high levels.


 

Fully Active B12 Benefits

 

• Supports nerve function:

Vitamin B12 is essential for the production of myelin, which is a protective coating that surrounds nerve fibers. Without enough vitamin B12, nerve function can become impaired, leading to neurological symptoms such as numbness, tingling, and muscle weakness.
 

• Increases energy levels:

As a cofactor in the metabolism of carbohydrates, fats and proteins, B12 helps the body convert these macronutrients into usable energy. Taking B12 supplements can help increase energy levels and fight fatigue, which can be especially helpful for those who lead busy or active lifestyles.
 

• Improves cognitive function:

B12 plays a crucial role in the production of neurotransmitters, including dopamine and serotonin, which are important for regulating mood and cognitive function. Studies have shown that B12 supplementation can help improve memory, focus and overall cognitive performance.
 

• Supports cardiovascular health:

High levels of homocysteine, an amino acid, have been linked to an increased risk of cardiovascular disease. B12 helps metabolize homocysteine, which can help lower blood levels of this compound and support cardiovascular health. In addition, B12 may also help reduce inflammation and improve blood vessel function, further supporting cardiovascular health.
 

• Supports immune system function:

B12 is needed for the production of white blood cells, which are important for fighting infections and other diseases. Studies have shown that B12 supplementation can help boost immune function and reduce the risk of infections, especially in older adults.
 

• Helps in the production of red blood cells:

B12 is essential for the production of red blood cells, which carry oxygen throughout the body. Without enough vitamin B12, red blood cell production can become impaired, leading to anemia and other complications.
 

• Supports bone health:

B12 helps the body metabolize bone tissue and has been shown to play a role in maintaining bone density. Studies have suggested that B12 supplementation may help reduce the risk of osteoporosis, especially in older adults.
 

• Promotes healthy skin, hair and nails:

B12 is necessary for the production of healthy skin, hair and nails. Without enough vitamin B12, these tissues can become dry, brittle and more prone to damage. B12 supplementation can help improve the health and appearance of these tissues.
 

• May improve mood:

B12 is involved in the production of neurotransmitters that regulate mood, including dopamine and serotonin. Studies have suggested that B12 supplementation may help improve symptoms of depression and anxiety, especially in those with low B12 levels.
 

• Supports healthy digestion:

B12 plays a crucial role in the production of stomach acid, which is needed to break down food and absorb nutrients. Without enough vitamin B12, digestion can become impaired, leading to symptoms such as bloating, constipation and diarrhea. B12 supplementation can help improve digestion and reduce these symptoms.
