Frequently Asked Questions

How much water should I drink per day? A common guideline is to drink half your body weight (in pounds) in ounces of water. For example, a 160 lb person would aim for about 80 oz per day. The Three Drops of Life 50oz bottle makes this easy to track — two fills gets you to 100 oz.

Is this water bottle dishwasher safe? We recommend hand-washing this bottle with warm soapy water to preserve the printed time markings over time. The Tritan plastic itself is dishwasher-safe on the top rack, but repeated dishwasher cycles may fade the markings.

What is Tritan plastic? Is it safe? Tritan is a copolyester made by Eastman Chemical. It is BPA-free, BPS-free, and does not contain phthalates. It is FDA-approved for food contact, shatter-resistant, and does not retain odors or flavors.

Does the 50oz bottle fit in a standard cup holder? At 50 ounces, this bottle is larger than a standard car cup holder. It is designed for desk use, gym benches, and backpack side pockets. The side grips make it easy to carry by hand.

How do I use the time markers on the bottle? Fill the bottle in the morning. The time markings on the side show target water levels for each hour. As you drink throughout the day, the water line should match or stay below the printed time — helping you pace your intake evenly.

Does this bottle come with a straw? No, this bottle uses a flip-top lid for direct drinking. The wide mouth also makes it easy to add ice cubes.
