What is DHA?
DHA fish oil is an omega-3 fatty acid that is a primary structural component of the brain, cerebral cortex, skin, sperm, testicles and retina. It can be synthesized from alpha-linolenic acid or obtained directly from maternal milk or fish oil. DHA, short for Docosahexaenoic Acid, is an important polyunsaturated fatty Acid for the growth and maintenance of nervous system cells. As an essential fatty acid for the growth and development of human retina and brain, DHA powder can promote the vision and intellectual development of infants, and has positive significance in maintaining brain function, delaying brain aging, preventing alzheimer's disease and neurological diseases, and preventing cardiovascular diseases.A lack of DHA in the human body can cause a range of symptoms including growth retardation, infertility and mental retardation.
At present, AHUALYN DHA products are mainly derived from deep-sea fish, marine microalgae and other Marine organisms, according to different sources known as fish oil DHA and algal oil DHA. And we can offer both DHA powder and oil.
Function
The essential n-3 fatty acid α-linolenic acid (C18:3) serves as an energy carrier and precursor for the synthesis of EPA (C20:5) and DHA (C22:6) into which it is converted by chain elongation and introduction of extra double bonds. EPA is an important component of the phospholipids of cell membranes and lipoproteins. DHA is a structural component in the cell membranes, particularly the nervous tissue of the brain, and plays an important role both for the synapses and the cells of the retina.
The conversion of α-linolenic acid to its long-chain derivatives EPA and DHA may not be sufficient to maintain optimal body functions. The limited conversion is mainly due to a dramatic change in eating habits during the past 150 years, resulting in increased n-6 PUFA intake and concomitant decrease in n-3 LCPUFA consumption in most industrialized countries. Therefore, the n-6 to n-3 ratio in our diet has changed from 2:1 to about 10 - 20:1. This change accounts for the inadequate biosynthesis of the biologically active n-3 PUFA, EPA, and DHA, as n-6 and n-3 PUFA compete for the same desaturase and elongase enzyme systems.
Application
DHA is widely used as a food supplement,it was first used primarily in infant formulas,to promote fetal brain development.
DHA has the antioxidant and Anti-Aging function.
DHA can improve Blood Circulation,and lower blood pressure,it can prevention and cure cerebral thrombosis.
DHA also can reducing blood fat.
DHA can help the transmission of nerves in the brain.
