Vitamin B4

Vitamin B4, often associated with Adenine and Choline, plays a crucial role in cellular metabolism, DNA/RNA synthesis, and the proper functioning of the nervous system and liver.

Functions and Benefits

DNA & RNA Synthesis: Acts as an essential building block for genetic material, aiding in cell division and protein synthesis.
Energy Metabolism: A key component of ATP, the primary energy currency of cells, supporting energy transfer.
Nervous System: Helps synthesize acetylcholine, a vital neurotransmitter for muscle control and memory.
Liver Health: Essential for maintaining liver cell membranes and preventing fatty liver disease.
