As long as it is capsules, tablets, spirulina powder and other (non-extract) products made of dry powder produced by spirulina with normal growth, it has certain health care function. Whether spirulina has health care function depends on spirulina itself, but it has no direct relationship with whether it has "Jian Zi" (police mobile unit) certification. Some people mistakenly think that only Jian Zi can have health care function, which is a naive and one-sided understanding of the certification of Jian Zi. The main reason for the certification of "police mobile force" in China is that many good spirulina products companies are unwilling to do it because its procedures are complicated and time-consuming and laborious, but this does not mean that the spirulina they produce is not good. We must correctly realize that China's "construction" certification is only a one-time certification of products, and there is no real real-time supervision. One-time authentication replaces real-time supervision. Such a threshold has no long-term significance for consumers.
Second, look at the color: real natural spirulina, 100%, regardless of powder, tablets, capsules, algae powder is dark green (not only look at the surface, but also look at the cross-section color) with yellow. Green spirulina is either fake or mixed with other substances. Because spirulina is very dry and easy to absorb moisture, it will gradually turn green after absorbing moisture, and it is easy to rot and deteriorate. Eating this spirulina is not only unhealthy, but also harmful.
3. Smell: Spirulina has a special smell of seaweed or ocean. It's definitely not spirulina. It doesn't taste like this. But what smells bad is probably fake and shoddy products.
Fourth, look at hardness: it can be distinguished by hand. The harder the spirulina is, the more other ingredients are mixed, and the high-quality spirulina can be separated by hand.
Taste: Spirulina is delicious and generally slightly alkaline. If the smell of alkali is heavy, it is not up to standard. In addition, 100% spirulina is sticky to chew.
Water-soluble observation method: put spirulina powder and tablets into a glass filled with pure water, and observe the color of the water after dissolution. If it is of high quality, the water should be green and gradually turn blue after half an hour.
Seven, look at the packaging: some nutrients of spirulina need to be isolated from the air, such as phycocyanin, carotene and so on. These nutrients lose 50% in sunlight 15 minutes. Therefore, in order to avoid direct contact with light and air and ensure that nutrients are not lost, large-scale spirulina production enterprises generally adopt light-tight sealed packaging.
Eight, the vast majority of spirulina products are made of spirulina dry powder as raw materials, therefore, the quality of their products mainly depends on the quality of dry powder raw materials, and whether there is functional addition or full addition in the processing process.
To remind everyone, spirulina itself is a nutritious package. In addition to the special need to extract a simple component from spirulina, any deep processing of spirulina will change or lose the original nutritional components of spirulina. All the so-called decomposed spirulina or extracts are not more nutritious than the original spirulina, so don't blindly believe in the so-called refined products.
Spirulina capsules or tablets are of reliable quality by well-known domestic brands.
