A comprehensive comparison of DHA from the United States and Australia: formula differences, cost-effectiveness, safety, which country is better?

Hello everyone, I am the assistant of Australian Encyclopedia. Recently, some friends asked me aboutAmerican and Australian DHA product selectionNow I will summarize the relevant issues and hope it will be helpful to those who want to know more.

1. Why does the choice of DHA depend on the country?

As an important component of Omega-3 fatty acids, DHA plays an irreplaceable role in the brain development of infants and young children, nutritional supplements for pregnant women, and cardiovascular health of adults. There are significant differences in the raw material sources, production processes, and regulatory standards of major DHA producing areas around the world:

• Raw material differences:Australia's DHA is mostly from small deep-sea fish species in the South Pacific (such as sardines and anchovies), while the United States often uses Alaska cod liver oil.
• Recipe design:Australian products emphasize the "clean label" concept (such as Blackmores and Bio Island), while American brands (such as Nordic Naturals) focus on functional additions.
• Regulatory system:TGA (Therapeutic Goods Administration) implements the world's most stringent drug-level supervision, and the US FDA manages it according to dietary supplement classification

Issues with DHA Selection

Question 1: Is it better to choose Australian or American brands of DHA for pregnant women?

It is recommended to give priority to Australian products because they have advantages in the following aspects:

1. Heavy Metal Control:Australia implements the AS 5008 standard, which requires mercury content to be ≤ 0.1 mg/kg (twice as strict as the EU standard)
2. DHA/EPA ratio:Pregnant women’s products mostly adopt the golden ratio of 5:1 (such as Elevit), which is more in line with the needs of pregnancy
3. Certification system:85% Australian DHA product passed GOED international certification (Global Omega-3 Organization)

Question 2: What differences should children pay attention to when supplementing with DHA?

From the actual test data (2023 third-party laboratory report):

Question 3: Comparison of cost-effectiveness of DHA products in the two countries

According to PriceMe price comparison platform data in 2024:

• Australian local price:Blackmores Infant DHA 60 capsules about $28 (average daily cost $0.47)
• US purchasing price:Nordic Children's DHA 90 capsules about $45 (average daily cost $0.5)
• Special formula:Australian Bio Island Pregnancy DHA with Lutein Formula is 15-20% cheaper than similar products in the United States

Question 4: How should the certification mark be interpreted?

There are three major certifications to focus on:

1. Australian TGA certification:The blue kangaroo logo indicates that the production standard has reached the pharmaceutical grade
2. USP certification:Diamond logo, mainly to verify the accuracy of ingredients
3. International IFOS certification:The five-star rating system currently has a 37% higher rate for Australian products than the United States

Question 5: Do I need to supplement other nutrients?

Recommended selection based on product combination:

• Australian special combination:DHA+folic acid+iodine (such as Elevit series)
• Common combinations in the United States:DHA + Vitamin E + Zinc (such as Nature's Blend)
• Special needs:Those who are allergic to dairy products can choose Australia Ocean Mild Seaweed DHA (no fishy smell formula)

Summarize:In terms of raw material safety, scientific formula and strict supervision, Australian DHA products are more suitable for sensitive groups such as pregnant women, infants and young children. American products have more choices in adult functional supplements (such as sports nutrition). It is recommended to purchase local hot-selling products through the official website of Australian pharmacies (such as Chemist Warehouse), and pay attention to the MFG logo in the batch number to confirm the place of production.
