We recommend a daily consumption of three to five 250ml (approximately8oz) glasses of water, tea, coffee, juices or other non-carbonated liquid with Willard Water® Clear or Ultimate concentrate added in the recommended dilution amounts. Adding the concentrate to fruit and vegetable juices you purchase from food stores or making personally will alkalize the water contained in the juice to an optimal level. Adding a small amount( coffee spoon) to your coffee will help to improve the pH+ balance of the coffee.
