FOR YOUR WELL-B-ING
The human body is a complex machine. To keep everything running smoothly—from your organs to your energy levels—you need a variety of nutrients, especially key micronutrients like vitamins and minerals. Prozis B-Complex delivers a powerful dose of all eight essential B vitamins: thiamin, riboflavin, niacin, pantothenic acid, vitamin B6, vitamin B7, folic acid, and vitamin B12.
B IN SYNERGY
Modern science confirms that every B vitamin plays a vital role in supporting key functions within the body. These functions are often interconnected and work best when the B vitamins function together. Here’s a quick look at some of the important roles B vitamins support:
Normal metabolism1
Normal nervous system2
Normal psychological function3
Tiredness and fatigue reduction4
Normal mucous membranes & skin5
Normal immune system6

Lab Tested
Backed by testing in advanced laboratories, this product is designed to meet high standards of quality and safety.
Why B-Complex?
B-Complex by Prozis provides at least 100% of each B-vitamin’s NRV (Nutrient Reference Value). Although we recommend obtaining your vitamins and other nutrients from food whenever and wherever possible, B-Complex is useful when you want to make sure that all your B-vitamin NRVs are met.
Who Is It For?
Prozis B-Complex is a great option for anyone wanting to ensure adequate B-vitamin intake. Since B vitamins are often found in animal-based foods, this supplement may be especially beneficial for those who eat less meat and dairy. Keep in mind, B-Complex is meant to complement a balanced diet, not replace it.
