Smart Water vs. Tap Water: Hydration Benefits

Smart Water aims to be the go-to drink for those on the move. Its added electrolytes help you stay hydrated during activities and come in different flavors.

Tap water provides a dependable and convenient source of hydration, fulfilling your body's needs and offering potential health benefits without breaking the bank. Remember, the exact mineral content might vary depending on your location, but it's still a safe and effective way to stay hydrated.

Note: The additional electrolytes may not provide substantial benefits beyond regular hydration if you have a balanced diet.

Smart Water vs. Tap Water: Safety and Health Implications

Tap water quality can differ depending on where you live, but local authorities always check and treat it. It usually involves filtering, cleaning, and regular tests for nasty stuff like metals or chemicals. Smart Water, the bottled choice, gets more purification than your tap. It goes through filters or reverse osmosis.

Note: Smart Water's safety depends on where it comes from and how it's made. Bottling and storing it can add new germs, even though the cleaning seems extra thorough.
