Best Before & Expiry Dates Explained

Best Before Dates Explained

Much like food items, sport supplements have a best before date. In the sports nutrition world expiration and best before dates serve as a guideline for how long a product remains potent and effective. However, if a product has a best before on Sept 1, 2018 will it still be good Sept 2, 2018? Of course it will. In fact, many products continue to hold their nutritional value years past their "best before date." as that is exactly what it is a "BEST BEFORE" date.
