Yes, all of these products can be safely taken together. In fact, we encourage you to take all three products together. This is why we have an option to buy them as a “Starter Pack” . The Lion’s Mane capsules work amazingly alongside the 1PD supplement. Individually, they work great, but together, they work even better. When taken together, they both enhance each other’s neuroprotective properties. The ginger capsules are included in the microdosing pack because when microdosing or indeed taking any supplements, some individuals experience slight nausea. Our ginger capsules can help negate this possible negative side-effect. Taking all 3 products together is recommended for the ultimate microdosing experience.
