Spirulina has a certain effect on constipation, which depends on everyone's situation. It is a kind of health food, and has no side effects after long-term use. The usual way to take it is to eat it after meals (about 2 grams), but if you need to use it to lose weight, you need to eat it before meals, and the amount should be large, about 5 grams.

Selection of Spirulina:

1. Selection of origin: Only three alkaline lakes with PH greater than 8.6 can grow natural Spirulina. These three lakes are Texcoco Lake in Mexico, Chad Lake in Africa and Chenghai Lake in Lijiang, Yunnan. In this way, the spirulina produced by Chenghai Lake is definitely the first choice (some people say that imported products are better than domestic ones, but are you sure about the origin of raw materials? ）。

2. Choose your own breeding base: Chenghai Lake now has only four spirulina breeding bases-Sprui (established in 1992, the head office of Green A), Lanbao (Chenghai brand in 1993), Yunhai (Chenghaihu brand) and Yongbao (formerly Hongyuan factory, Paul brand). Two bases of Lanbao have been sold (leased) to Greenstone Company (Chenghai Brand) and Tiantian Company (Xianzao Brand). It is said that the raw materials of several breeding bases are basically for personal use and are rarely sold.

3. brand selection: if you know the situation of the base, you will be better than the manufacturer. Sprui is a well-deserved top seed player. It has the largest spirulina breeding base in the world at present, producing two kinds of spirulina with excellent quality: medicine brand (Sprui brand) and Jian brand (Green A).

to sum up, green a brand is the best and the quality is the best, which should be beyond doubt.

incidentally, I have been eating Chenghai brand (Sapphire) for many years, and I eat Green A when someone gives it to me.
