B-vitamiinikompleksi

What is Vitamin B Complex?

Vitamin B Complex refers to the group of eight water-soluble B vitamins that work together as essential cofactors in cellular metabolism. The eight B vitamins are thiamin (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), vitamin B6, biotin (B7), folate (B9), and vitamin B12. What makes this group exceptional is the degree to which these vitamins cooperate — many B vitamin-dependent enzymes require multiple B vitamins simultaneously, and a shortfall in any one can limit the function of others. This synergy is why B vitamins are most effective when taken together as a complete complex.

B-vitamiinit ovat kehon aineenvaihdunnan työhevosia. Ne ovat välttämättömiä kofaktoreita entsyymeille, jotka muuntavat hiilihydraatteja, rasvoja ja proteiineja käyttökelpoiseksi energiaksi (ATP), mielialaa ja kognitiivista toimintaa säätelevien hermovälittäjäaineiden synteesille, punasolujen muodostukselle, homokysteiiniaineenvaihdunnalle ja hermoston ylläpidolle. Koska elimistön varastointikyky on useimpien B-vitamiinien osalta rajallinen, säännöllistä päivittäistä saantia tarvitaan optimaalisten tasojen ylläpitämiseksi. Kattava B-vitamiinikompleksi toimittaa kaikki kahdeksan B-vitamiinia saannin vertailuarvoina yhdessä päivittäisessä kapselissa.

EFSA-approved health benefits

The European Food Safety Authority (EFSA) has confirmed that the B-vitamin group:

• contribute to normal energy-yielding metabolism
• contribute to the normal functioning of the nervous system
• contribute to normal homocysteine metabolism (B6, B12, folate)
• contribute to normal psychological function
• contribute to the reduction of tiredness and fatigue
• contribute to the normal function of the immune system
• contribute to normal red blood cell formation (B6, B12)
• contribute to normal cell division (B12, folate)

In addition, individual B vitamins carry specific claims:

• Thiamin contributes to normal heart function
• Riboflavin contributes to the maintenance of normal vision and the normal metabolism of iron
• Niacin contributes to the maintenance of normal skin
• Pantothenic acid contributes to normal mental performance and the normal synthesis and metabolism of steroid hormones, vitamin D, and neurotransmitters
• Vitamin B6 contributes to normal cysteine synthesis, protein and glycogen metabolism, and the regulation of hormonal activity
• Biotin contributes to the maintenance of normal hair and skin
• Folate contributes to normal amino acid synthesis and maternal tissue growth during pregnancy

Why we use a Complete B Complex in Nutri-Leaf formulas

Nutri-Leaf Vitamin B Complex provides all eight B vitamins at 100% NRV per capsule in their active, bioavailable forms. We use methylcobalamin (active B12), pyridoxal-5'-phosphate (active B6), riboflavin-5'-phosphate (active B2), and active folate (5-MTHF) rather than the more common synthetic forms. This active-form approach means the vitamins are ready for the body to use immediately, without requiring additional metabolic conversion. The formula provides comprehensive daily B vitamin support in a single plant-based HPMC capsule.
