The capsules have a different color than before

Mushroom extracts are based on natural products. There will always be small variations in color. Apart from that, sometimes a new way of processing the products can also result in a significantly lighter or darker color. But the color in itself is not really important.

In the end the only thing that really matters is what is in the product - the active ingredients. Check the supplement facts label and, when in doubt, ask for a recent test report.
