Vitamin O is a special supplemental oxygen taken in liquid form produced through electrical-activation with saline solution from the ocean. Vitamin O has been one of our most popular products for over twenty years because of the benefits people are seeing in their health. Thousands of satisfied customers use it every day to improve and maintain their health. We trademarked the name Vitamin O not because we are claiming that it is an actual vitamin but because it is a powerful way to deliver supplemental oxygen to the body and oxygen is a vital element for all our lives. Vitamin O is an amazing nutritional supplement and is quite simply ahead of its time in many respects.
