Klaire Labs’ B-Complex Plus is a supplement that contains an exclusive and effective formula in order to provide you with:

  • A maximum-strength B-vitamin complex‚ for energy throughout the day

  • Robust support for increased endurance

  • Much-needed help for maintaining mental alertness‚ even during periods of fatigue

Each vegetarian capsule gives you valuable relief from stress-filled modern life. Work‚ family‚ and friends can drain your energy; in fact‚ research has shown that the body uses up B-vitamins significantly more quickly than normal when experiencing anxiety. Unfortunately‚ this can result in a shortage of the very vitamins you need to preserve an alert mind—a lack of alertness may then cause you to make mistakes or errors that compound your existing stress.

Another factor contributing to the loss of B-vitamins is that they’re water-soluble‚ meaning that your body is unable to store large amounts of them. Instead‚ water-soluble vitamins are eliminated through the urine a relatively short period of time after consumption. If you don’t continuously replenish your supply of B-vitamins‚ a deficiency may result sooner than you’d expect. As a consequence‚ it’s essential that you frequently replace the lost B-vitamins in order to maintain optimal health. In their role as co-enzymes‚ B-vitamins effectively link with apoenzymes in order to become active enzymes. Subsequently‚ these enzymes adopt the function of catalyzing agents in the chemical reactions which are involved with transfer of energy from food consumed and stored inside the human body.

B-Complex Plus was carefully developed to deliver the essential B vitamins required for the peak functioning of many systems and biochemical reactions within your body. These include the production of energy; brain‚ liver‚ and nerve cell functioning; and muscle tone in the gastrointestinal (GI) tract. Its formula utilizes the activated versions of folate and vitamin B-12‚ due to their effectiveness and enhanced absorption.

Importantly‚ this B-Complex Plus vitamin supplement is hypoallergenic and yeast-free. In addition‚ it’s also free of sugar‚ salt‚ soy‚ dairy products‚ gluten‚ artificial coloring‚ and artificial flavoring.

Klaire Labs is a leader in providing hypoallergenic probiotics‚ and has been serving health care professionals for over 40 years. Its supplements are free of gluten and dairy. The company regularly partners with researchers and clinicians to formulate products ideal for patients that need gastrointestinal support.
