There is no exact way to say how much DHA is best for babies. Generally, babies aged 0 to 3 years old can consume 100mg of DHA per day, but there is no clear recommended dosage for children and adolescents over the age of 4 years old. DHA, which stands for docosahexaenoic acid, is an omega-3 essential fatty acid, a nutrient required by cells of the nervous system in their growth and maintenance, and an important structural component of the retina and brain. The human body synthesizes docosahexaenoic acid can use the essential fatty acid linolenic acid, but the synthesis function of infants and young children is much lower than that of adults, so they need to be supplemented, generally 0 to 3 years old babies daily intake of 100mg DHA can be for children and teenagers between the ages of 4 and 17 years old, and there is no clear recommended dosage, you can supplement as needed. When babies need to supplement DHA, they should do so under the guidance of a doctor.
