Functional mushrooms, like Lion's Mane and others, have been consumed for their potential cognitive benefits. However, as with any supplement or dietary addition, it's essential to consider possible side effects or interactions with other medications or conditions.  Some individuals might experience digestive discomfort, allergies, or skin rashes, although these side effects are relatively uncommon. It's always advisable to start with a small dose to monitor your body's reaction. When considering functional mushrooms for brain health, it's also crucial to consider potential interactions with medications or underlying health conditions.  We recommend consulting with a healthcare professional before adding these or any supplements to your regimen. They can provide personalized advice based on your health status, existing medications, and individual needs, ensuring safety and efficacy in supporting cognitive health.
