About our products

For over 30 years, Gandalf products have been renowned for their exceptional quality. To ensure this quality, we guarantee that all products will have an expiration date of at least six months from the date of delivery.

Spirulina is highly sensitive to light and air, which is why our packaging offers optimal protection. Our bags are made from high-quality materials and consist of multiple layers, including one made of aluminum, providing effective protection against air and light, ideal for preserving the product. In comparison, plastic containers are less effective as they can allow air and light to pass through, thereby compromising the quality of the spirulina. Additionally, plastic can release harmful substances. While glass is less reactive than plastic, it is transparent and allows light to pass through, which can degrade the nutrients in spirulina and reduce its effectiveness. Our aluminum-layered packaging offers superior protection against these factors, ensuring the product’s freshness over the long term.
