What Is BioActive Complete B-Complex?

Are you getting enough vitamin B? There are more forms of it than you may think, and each plays a different role. So it’s important to get a wide spectrum of the vitamin B family, every day. BioActive Complete B-Complex is made with the biologically active forms of each nutrient, optimizing absorption and giving your body what it needs to thrive.

Getting your Bs doesn’t have to be difficult. Get the biologically active forms of these vitamins you need to thrive.

BioActive Complete B-Complex Benefits

  • Boosts energy production and promotes a healthy metabolism
  • Encourages brain, cellular and organ health
  • More biologically active so your body can use each nutrient more effectively

What is pantothenic acid?

Vitamin B5, or pantothenic acid, supports hemoglobin synthesis, hormone and neurotransmitter health, as well as carbohydrate and fatty acid oxidation.

Why add pyridoxine and pyridoxal?

Vitamin B6 in the form of pyridoxine HCI and pyridoxal 5'-phosphate affects amino acid and lipid metabolism, neurotransmitter health, and hemoglobin synthesis.

Why we use bioactive B vitamins

The B vitamin family supports the proper assimilation of nutrients and energy from the foods you eat. But before your body can use B vitamins, it must first convert them into their biologically active forms. That’s why we created BioActive Complete B-Complex—it combines the active forms of each of the eight B vitamins, so your body can skip a step and directly access the many health benefits these essential nutrients offer.

Why Should I Supplement With BioActive Complete B-Complex?

You've probably heard of vitamins B6 and B12, but did you know that there are a total of eight B vitamins? Each one benefits you in different ways—from promoting the healthy metabolism of glucose, fat, and alcohol, to encouraging your energy production. They even support your organ function, cognitive health, and more.

But many of us aren't getting enough of these essential B vitamins.

To help your body thrive, Life Extension created BioActive Complete B-Complex. Packed with multiple forms of biologically active vitamin B and using the same doses as the latest research, it's the perfect complement to any well-rounded nutritional regimen.
