I know two well-known nucleic acid products, one is Zhen 'ao nucleic acid from Dalian, and the other is Yuan Di Rudy nucleic acid from Zaozhuang. Zhen 'ao nucleic acid came out earlier, and the market is bigger, but from the perspective of product quality and development prospect, Yuan Di Rudy nucleic acid is slightly better, because it is capsule granular and obtained from Liaoning Provincial Health Department. People who know this major should know that nucleic acids are not easily soluble in liquids, especially acidic liquids. Yuan Di overcame this difficulty and obtained a patent, which made the product more easily absorbed by the human body, and the effect was naturally good, and it was not easy to cause waste. This product has obtained the approval certificate issued by the Ministry of Health, which is quite authoritative. The company's products have been sold for more than ten years and have a good reputation. At present, we haven't seen any reports of quality problems.
You can check on the websites of these two companies, so I won't say much here.
