Yes. Nima guarantees capsule shelf life of 2-5 months from delivery. Each capsule has an expiration date printed on the box, the foil package and the capsule itself. The expiration dates are used to ensure the live antibody-based chemistry is fresh and your test is accurate.
The expiration dates on the capsules are displayed in month-day-year format. Use older capsules first and newer ones last. If a capsule is beyond its expiration date, throw the capsule away.
As Nima makes advancements in the shelf life of the capsules, we will make sure to keep the community posted!
