BioActive Complete B-Complex – Daily Energy, Nervous System, Metabolism and Stress, with Bioactive Forms of B Vitamins

BioActive Complete B-Complex, Life Extension is a full-spectrum B vitamin complex, formulated to provide high doses, in bioactive forms easily utilized by the body. Each tablet provides thiamine (B1), riboflavin (B2), niacin (B3), vitamin B6, folate in its methylated form L-5-MTHF, vitamin B12 methylcobalamin, biotin, pantothenic acid (B5), alongside inositol, PABA and calcium.

Due to high concentrations and combination of active forms (riboflavin 5'-phosphate, pyridoxal 5'-phosphate, methylcobalamin, L-5-methyltetrahydrofolate), this complex is designed to support cellular energy, nervous system functioning, carbohydrate, protein and fat metabolism, neurotransmitter synthesis and maintaining skin, hair, nail and cardiovascular system health.

Detailed Benefits of BioActive Complete B-Complex, Life Extension

• Supporting optimal cellular energy levels

B complex vitamins are directly involved in cellular energy production, especially in transforming carbohydrates, fats and proteins into ATP – the main "fuel" of cells.
 

• Thiamine (100 mg) plays a key role in the Krebs cycle and carbohydrate metabolism, supporting efficient energy production.

• Riboflavin (75 mg), in the form of riboflavin and riboflavin 5'-phosphate, participates in redox reactions, being essential for the mitochondrial respiratory chain.

• Niacin (100 mg) enters the structure of NAD/NADP coenzymes, involved in hundreds of energy production reactions.

Through high and combined intake of these vitamins, the complex can contribute to:
✅ Reducing fatigue and exhaustion sensation
✅ Supporting energy level throughout the day
✅ Optimal cell functioning under conditions of increased physical or intellectual stress

This makes it suitable for people with demanding lifestyles, intense work periods or increased physical activity.

• Supporting nervous system and cognitive functions

B vitamins are essential for nervous system health, for neurotransmitter synthesis and for maintaining balanced mental state.
 

• Vitamin B6 (100 mg, pyridoxine HCl + pyridoxal 5'-phosphate) is involved in synthesis of serotonin, dopamine, GABA and other brain chemical mediators.

• Vitamin B12 (300 mcg, methylcobalamin) supports myelin formation, neuronal function and energy production in nerve cells.

• Folate in its methylated form (680 mcg L-5-MTHF) participates in the methylation cycle, essential for neurological function and neurotransmitter balance.

Through these mechanisms, BioActive Complete B-Complex can contribute to:
✅ Mental clarity and better concentration
✅ Supporting memory and cognitive processes
✅ Emotional balance, especially during stress and psychological demand periods

• Carbohydrate, fat and protein metabolism

Efficient metabolism means optimal transformation of nutrients into energy and structural components. Life Extension's B complex offers significant doses to support these processes:
 

• Pantothenic acid (B5) in very high dose (500 mg) is a component of coenzyme A, involved in fatty acid oxidation and numerous metabolic reactions.

• Niacin, thiamine, riboflavin and B6 contribute to degradation and utilization of proteins, lipids and carbohydrates at cellular level.

Potential benefits:
✅ Supporting energy metabolism, even during intense effort periods
✅ Optimal functioning of enzymes involved in digestion and nutrient utilization
✅ Support for people with varied diets, rich or poor in certain macronutrients

• Supporting homocysteine levels and cardiovascular health

Folate, vitamin B6 and vitamin B12 work together in homocysteine metabolism – an amino acid with cardiovascular health impact when its levels are elevated.
 

• L-5-MTHF (methylated folate) is the active, directly usable form, without depending on enzymatic conversion.

• Methylcobalamin (B12) and B6 co-manage remethylation and transsulfuration reactions involved in homocysteine transformation.

By supporting these metabolic pathways, the complex can contribute to:
✅ Maintaining healthy homocysteine metabolism
✅ Support for vascular and circulatory health
✅ Long-term cardiovascular system protection, as part of a balanced lifestyle

Skin, hair, nails and tissue health

B vitamins are closely linked to rapidly dividing tissue health and external appearance:
 

• Biotin (1,000 mcg) is known for its role in maintaining hair, skin and nail health.

• Niacin and riboflavin support skin and mucous membrane integrity.

• Pantothenic acid and B6 contribute to tissue regeneration and metabolism of lipids forming skin barrier.

Thus, BioActive Complete B-Complex can support:
✅ Healthy skin appearance
✅ Stronger hair and more resistant nails
✅ Efficient tissue regeneration, as part of normal physiological processes

• Stress management and psycho-emotional balance support

Physical and mental stress increases B vitamin requirements, as they are involved in body adaptation reactions.

• Thiamine, B6, niacin and B12 support normal nervous system functioning, reducing perceived stress impact on the body.

• Inositol (100 mg) and PABA (50 mg) complete the formula, contributing to cellular metabolism and supporting good tissue-level functioning.

Through generous B vitamin intake, the product:
✅ Supports body resilience during demanding periods
✅ Contributes to maintaining nervous and emotional balance
✅ Supports adaptation to daily stress through optimal neurotransmitter and energy metabolism

• Bioactive forms for optimal body utilization

A major advantage of BioActive Complete B-Complex is the use of bioactive and well-studied forms:
 

• Riboflavin 5'-phosphate – coenzyme form of vitamin B2

• Pyridoxal 5'-phosphate – coenzyme form of vitamin B6

• L-5-methyltetrahydrofolate – active folate form, ready for use

• Methylcobalamin – methylated form of vitamin B12, directly involved in methylation reactions

These forms can be more easily recognized and utilized by the body, contributing to:
✅ Increased metabolic efficiency
✅ Optimal support for people wanting advanced and modern B vitamin forms
✅ Covering basic needs and increased needs during stress, effort or intellectual demand periods

Through balanced combination of B vitamins in high doses, bioactive forms and complementary nutrients (inositol, PABA, calcium), BioActive Complete B-Complex, Life Extension is complex support for energy, nervous system, metabolism, skin and general health, suitable for those wanting a complete and advanced vitamin B complex.
