At first, Dunaliella salina was mainly used to extract carotene, but now it is sold as Dunaliella salina tablets. The essence is that spirulina has become popular and the price has been reduced accordingly, so the merchants will launch a Dunaliella salina that the public has never heard of to boost profits, hehe.

In addition, it is best to look at the origin of microalgae in Chu Qing (note that it is a breeding and production place). If it is made in China, I will be very happy. This thing can be mass-produced in China, but judging from my experience in microalgae industry for more than ten years, it is better to be careful about the quality.
