I rarely write reviews, however, I have been taking spirulina for years and had no idea about the quality. I did some research and came across Royal Spirulina and really appreciated all the information they provide. I ordered and it is a bright green that I have never seen. After taking it , I realized quality does matter and this company is great. I have been ordering for almost a year now and I will continue to do so. Yes, it is pricey but my labs show that it works!
