This can be taken with or without food but we'd obviously recommend the optimal way which is sublingual at approx. 0.5 to 1g per day.  That being said there is more and more research on gut absorption being proven (please see below).  NMN Transporter (Slc12a8) proves ingested-NMN enters cells directly and is absorbed in the GUT, within 2-3 min, creating NAD+ in tissue at 10-30 min. Meaning it's okay to take with food.  NMN Promotes DNA Repair & Turns on our longevity-genes known as SIRTUINS. NMN also supports stamina, endurance & ENERGY Production. Studies suggests NMN may promote healthy heart, blood flow, eye, brain, bone, muscle and immune function.  *Not tablets or capsules / caps.
