The Best Time for Infants to Take DHA

DHA (docosahexaenoic acid) is a highly unsaturated fatty acid essential for the growth and maintenance of nerve cells in the nervous system, and is indispensable for optimal brain nutrition. It is also a critical structural component of both the brain and retina. DHA is primarily found in fish oils—especially in the fat of deep-sea fish—and offers multiple health benefits, including enhancing cognitive function, preventing cardiovascular disease, and boosting immune function. So, when is the optimal time for infants to consume DHA? Below, we address this question.

Optimal Timing for DHA Supplementation in Infants

Generally speaking, because DHA supports brain development, it is recommended that infants begin supplementation between 6 months and 2 years of age—the period of most rapid growth and development. During this window, DHA helps synthesize crucial neurotrophic hormones vital for brain maturation, thereby meeting the infant’s heightened developmental needs. Additionally, DHA is best taken after breakfast, as absorption is more efficient under these conditions; taking it on an empty stomach is discouraged, as it may impair nutrient absorption. For pregnant women, DHA supplementation is advised starting from the fourth month of gestation. Complementary dietary sources—including milk, soy milk, eggs, fish, and tofu—can further support maternal nutritional requirements.

Knowledge Extension: Benefits and Functions of DHA

1. Enhances Brain Function and Cognitive Development

DHA is an essential nutrient for the formation and development of brain cells. It promotes and coordinates neural signal transmission across synaptic circuits, thereby supporting normal neuronal function. Appropriate DHA supplementation can improve memory, enhance concentration, and strengthen comprehension. Moreover, it helps stimulate mental agility and may reduce the risk of age-related cognitive decline, including Alzheimer’s disease.

2. Boosts Immune Function

As a polyunsaturated fatty acid, DHA increases cell membrane fluidity, thereby enhancing the activity of immune cells and strengthening overall immune function. Furthermore, DHA exhibits anti-inflammatory properties, making it beneficial in managing various inflammatory conditions—such as rheumatoid arthritis.

3. Supports Cardiovascular Health

As a polyunsaturated fatty acid, DHA helps maintain vascular patency, prevents thrombus formation, and reduces the risk of stroke or myocardial infarction. Additionally, DHA aids in clearing excess lipids from the bloodstream, thereby helping prevent atherosclerosis and peripheral vascular occlusion—playing a significant role in cardiovascular disease prevention.

The above outlines the optimal timing for DHA supplementation in infants. We hope this information proves helpful to you.
