What are the sources of DHA?

Breast milk:

Generally, the DHA content in breast milk is about 0.3% of the total fatty acids, making it the best source of DHA. However, the DHA content in breast milk is closely related to the mother's diet and nutritional status. Whether the DHA in breast milk meets the baby's needs depends on the baby's development.

Formula milk:

The DHA added to formula milk powder is usually of two types: fish oil type and algae oil type. Fish oil DHA has a high probability of being contaminated, so algae oil DHA is currently the main type. In formula milk added with DHA,dha algal oil powder the DHA content should reach 0.2%-0.5% of the total fatty acids, which is about 20~60mg/L.

Deep sea fish oil:

Fish oil is rich in DHA and EPA (eicosapentaenoic acid), and fish oil mainly comes from deep-sea fish. As environmental pollution becomes more and more serious, fish oil has been found to contain organochlorine pollutants, as well as heavy metals, dioxins, and toxaphene. In addition, fish oil contains a certain proportion of EPA, and early studies found that excessive intake of EPA may affect infant weight growth. EPA has the effect of lowering blood lipids and diluting blood, so DHA and EPA extracted from deep-sea fish oil are beneficial to the elderly and adults. (Tips: Fish oil comes from the subcutaneous fat of deep-sea fish and mainly contains DHA and EPA; cod liver oil comes from fish liver and mainly contains VA and VD.)

Algae Oil DHA:

Marine microorganisms such as seaweed are the original producers of omega-3 unsaturated fatty acids. At present, a variety of marine microorganisms rich in DHA and EPA have been isolated, mainly some lower marine fungi and microalgae. Compared with fish oil, algae oil DHA has some incomparable advantages. They are pure natural green food with no heavy metal residues, pure vegetarian food, no fishy smell, sustainable renewable resources, and reliable sources.

The DHA extracted from seaweed oil is most beneficial to the absorption of infants and young children, and can effectively promote the development of the baby's retina and brain. Mothers, please choose algae DHA, which is more suitable for infants and young children. Single-cell algae in the ocean can synthesize DHA themselves. Most deep-sea fish get DHA from eating seaweed.

Indirect sources:

The DHA precursor (alpha-linolenic acid) in nature is widely found in nuts and vegetable oils, such as flaxseed oil, sunflower seeds, peanuts and other nuts. It can be partially converted into DHA in the body and thus used by the body. However, the conversion rate of α-linolenic acid is not yet clear. What is certain is that α-linolenic acid in oils such as nuts is as important as directly supplementing DHA and is an indispensable source for the human body to obtain sufficient DHA.
