BioActive Complete B-Complex by Life Extension

Fuel your body with the vitamins it needs to thrive. Life Extension’s BioActive Complete B-Complex is a scientifically formulated supplement that provides the full range of B vitamins in their most potent, easily absorbable forms. This isn’t just another B-complex; it’s a smarter way to support your energy, metabolism, brain, and cardiovascular health.

Why BioActive B Vitamins Matter

Standard B vitamins often need to be converted by the body into their active forms before they can be used—a process that can be inefficient for some individuals. Our BioActive formula bypasses this step by providing the enzymatically active coenzyme forms, such as Riboflavin 5′-phosphate (B2) and L-5-methyltetrahydrofolate (Folate). This “body-ready” approach ensures you get the maximum benefit from every capsule.

Comprehensive Support for Whole-Body Health

• Healthy Energy Metabolism: B vitamins are crucial for unlocking the energy from the foods you eat, helping to convert carbohydrates, fats, and proteins into cellular fuel.
• Brain & Nervous System Health: This complex helps synthesize neurotransmitters and supports healthy cognitive function, a sharp mind, and nerve health.
• Cardiovascular Support: B vitamins, especially folate and B12, help maintain healthy homocysteine levels, a key marker for cardiovascular wellness.

How to Use

For optimal results, take two (2) vegetarian capsules daily with food, or as recommended by your healthcare practitioner. Taking with a meal can enhance the absorption of the B vitamins.

Important Safety Information

Please consult with your healthcare provider before use. Temporary flushing, itching, rash, or gastric disturbances may occur when taking products containing niacin. Keep out of reach of children and do not exceed the recommended dose.

Frequently Asked Questions (FAQ)

What does “bioactive” mean for a B vitamin?

“Bioactive” means the vitamin is in the same active form your body naturally uses. This allows your body to absorb and utilize it directly without having to go through a conversion step, making it more efficient.

Why does my urine turn bright yellow after taking this?

This is a normal and harmless effect of taking B vitamins, particularly Vitamin B2 (Riboflavin). It’s simply your body excreting the excess water-soluble vitamins it doesn’t need.
