There are many products selling DHA online, with various banners, such as raw materials, effects, and prices. In short, if there is no special feature, find some features to make it a selling point. The ones with special features will naturally be unlimited. Magnify your features to attract buyers. The most terrible ones are those selling fake products, using ordinary raw materials as high-quality raw materials to deceive consumers. For ordinary consumers, it is really difficult to distinguish the pros and cons of these products because of the lack of product-related knowledge. Here are some tips on how to identify DHA, which may come in handy.

1. Look at the product type. DHA is divided into fish oil DHA and algae oil DHA. The traditional source of DHA is extracted from deep-sea fish oil. Fish accumulate DHA in their bodies through marine microorganisms in the food chain. Therefore, marine microorganisms are the original producers of DHA. Due to the influence of environment and climate, the quality of deep-sea fish oil products often varies greatly. In addition, due to environmental pollution, DHA extracted from fish oil is inevitably contaminated by heavy metals and persistent organic pollutants (such as organochlorines). Moreover, deep-sea fish oil contains cholesterol and EPA (eicosapentaenoic acid) that cannot be removed. EPA can inhibit the growth and development of children and adolescents, affect fetal growth, damage blood platelets and cause blood to clot easily, among other side effects. Therefore, most fish oil products are not suitable for pregnant women.

DHA extracted from seaweed does not contain EPA, is 4 times as pure as fish oil, contains no cholesterol, does not contain marine organic pollutants, has no side effects, and heavy metal residues comply with EU standards. This magical seaweed that can grow DHA on its own is grown in large stainless steel fermentation tanks commonly used in the pharmaceutical, food and biotechnology industries. The entire production process from beginning to end is in full compliance with the FDA (U.S. Food and Drug Administration ) requirements to ensure the production of high-quality and uniform products and eliminate any possible risk of environmental contamination. The result is Martek's life's DHA, a pure, amber-colored vegetable oil rich in DHA.

2. Look at the raw materials. The most important principles for pregnant women to supplement DHA are "safety" and "effectiveness." The safest and most effective raw material in the world comes from Mattek DHA. Martek DHA currently accounts for 75% of the DHA market share in the world's infant formula field and 96% of the U.S. market.

3. How to identify the authenticity of Mattek raw materials. Be sure to look at the packaging for the following markings. As long as the algae oil DHA is truly provided by Martek, the company will authorize it to use its life's DHA trademark. If the domestic manufacturer is really its raw material, it will definitely not fail to put this label on it.

Second, you can call Mattek to check the manufacturers and product brands it cooperates with. This is the simplest and most effective method.

4. Price. If it is genuine Mattek raw material and the daily intake is sufficient (pregnant women need to supplement DHA 200~300mg every day), the price of a month's DHA product should be more than 300 yuan. Of course, companies will have different pricing ranges based on other input costs and profit pursuits of the product, but the price will generally not be lower than 300 yuan.
