GNC is a long-established health and nutrition food chain and one of the most well-known health care product brands in the United States. GNC has a rich product line, including more than 1,500 kinds of dietary supplements such as vitamins and minerals, sports health and nutrition products, with annual sales of more than 600 million bottles.
 
GNC's fish oil product is only a small part of its product line, but the specific division is not clear, and it mainly sells concentrated fish oil. GNC fish oil mainly comes from small deep-sea fish at the bottom of the food chain, such as anchovies and sardines, and has less contaminant accumulation.
 
In terms of fish oil concentrate, GNC has three products: TRIPLE STRENGTH FISH OIL, TRIPLE STRENGTH FISH OIL MINI and COENZYME Q10 SUPPLEMENT. GNC fish oil concentrate is high in Omega-3 content, but the particles are particularly large, each grain of fish oil is more than 1.5g, and some people may have difficulty swallowing. The content of MINI fish oil concentrate is not much different from that of normal fish oil concentrate, the particle size is only half, it is easier to swallow, and you can take 2 capsules a day.
 
The EPA content of GNC concentrated fish oil is much higher than that of DHA, which is not suitable for pregnant women and children, and is more suitable for middle-aged and elderly people with hidden cardiovascular diseases. If you want to use it for pregnant women, GNC DHA250 is suitable for the requirements, each capsule contains 250mg of DHA, EPA 100mg, and you can take 1~2 capsules a day.
 
In April 2018, the fish oil evaluation released by China's "Consumer Reports" showed that the peroxide value of Jian'anxi lemon-flavored 300mg fish oil was high, 5.6nmol/kg, which exceeded the limited requirements for fish oil in the aquatic industry standard "SC/T 3503-2000 (polyene fish oil products)" (glycerol ester peroxide value ≤5mmol/kg, acid value ≤1.0mg/kg), and it was not recommended to buy this product.
 
In the evaluation of similar products, it is difficult to explain the overall quality problem through a batch of samples, and in general, there is no serious problem with the overall quality of Jian'anxi fish oil.
