Look at the details
Compare the actual label, serving size and ingredient list when looking at similarly named drinks. Hydration drinks and energy drinks are different product categories. Check the information and cautions on the particular package; this guide makes no nutrition or performance claims.
Keep a useful record
For a collection, save the exact item name, identifying details and condition notes alongside your own photographs. For daily use, keep the care or setup instructions somewhere easy to find. A clear description is more useful than a broad category name when you return to a piece later.
