USA Onhand | 21st Century, B-6 & B-12 ( Energy Support )

"21st Century, B-6, 100 mg, and B-12" likely refers to two separate dietary supplements containing vitamin B6 and vitamin B12, respectively. Here's an overview of each:

Vitamin B6 (Pyridoxine):

Vitamin B6 is a water-soluble vitamin that plays a crucial role in various bodily functions, including metabolism, neurotransmitter synthesis, and immune function.

It is involved in the metabolism of amino acids, carbohydrates, and lipids, making it important for energy production and nutrient metabolism.

Vitamin B6 is also essential for the synthesis of neurotransmitters such as serotonin, dopamine, and GABA, which are involved in mood regulation and cognitive function.

Additionally, vitamin B6 is important for immune function and the synthesis of hemoglobin, which carries oxygen in red blood cells.

The recommended daily intake of vitamin B6 for adults is around 1.3 to 1.7 mg, although higher doses may be recommended for certain individuals or conditions.

Vitamin B12 (Cobalamin):

Vitamin B12 is another water-soluble vitamin that is essential for various bodily functions, including red blood cell formation, DNA synthesis, and nerve function.

It plays a key role in the metabolism of fatty acids and amino acids, making it important for energy production and the maintenance of a healthy nervous system.

Vitamin B12 is particularly important for red blood cell formation, as it is required for the synthesis of hemoglobin and the maturation of red blood cells in the bone marrow.

It is also involved in the maintenance of myelin, a fatty substance that coats and protects nerve fibers, making it essential for proper nerve function.

The recommended daily intake of vitamin B12 for adults is around 2.4 micrograms (mcg), although higher doses may be necessary for individuals with certain conditions that affect absorption or metabolism of the vitamin.
