This DHA is extracted from seaweed and is healthier. I know Echemi, a very large and best company in China. It buys products from many very large manufacturers in China for sales, because China's labor costs are very low. But technology is enough to satisfy the extraction of these best things, so I bought it decisively. For these products from China, only the best can be exported, otherwise the customs will not export them, so you can buy them with confidence. I am in love with this product, you must buy it.
