1. For pregnant women and lactating women, timely and appropriate DHA supplementation can maintain the balance between pregnancy health and DHA, increase the DHA content in breast milk, and effectively promote the development of fetal and infant cranial nerves and optic nerves.

2. For babies, 0-3 years old is a critical period for their brain development. Parents should ensure that their children get enough DHA, promote the development of brain and optic nerve, and improve their vision and cognitive ability.

For growing children, DHA supplementation can improve cognitive ability, attention and memory.

4. For adults, reasonable DHA supplementation can maintain adult brain and eye functions, maintain normal cognitive ability, and most importantly, have anti-aging function.

For middle-aged and elderly people, DHA in the brain will gradually decrease with age, which will easily lead to the deterioration of brain function. Therefore, a reasonable amount of DHA supplementation can reduce the risk of Alzheimer's disease, prevent "three highs" and improve their memory to some extent.
