According to EatByDate, as long as a bottle of Gatorade has been securely sealed, there should be no adverse effects from consuming it after the expiration date printed on the bottle. There may be a minor variation in flavour and colour, but there are no health concerns associated with drinking it.
The drink-by date on Gatorade bottles is not necessarily the expiration date. Instead, they provide the date through which the maker assures the product’s freshness and flavour. To ensure that Gatorade can be consumed past the expiration date on the bottle, store it in a cool, dark location and ensure that the seal is not compromised.
