THORNE B-Complex #12 — Active B Vitamins with Methylfolate & Methylcobalamin, 60 Capsules, One‑Per‑Day

THORNE B-Complex #12 is a comprehensive B-vitamin capsule delivering eight water-soluble B vitamins plus choline in active, methylated forms to support cellular energy and nervous system function.*

Made by THORNE, this B-Complex blends B1, B2, B3, B5, B6, B12, folate and biotin with choline in a single daily capsule. The formulation uses bioactive forms of folate (5-MTHF) and vitamin B12 (methylcobalamin) to improve cellular uptake and biochemical readiness. Third-party testing verifies label accuracy, and THORNE’s reputation includes professional athletic support and high practitioner recommendation.

What does this B-Complex contain and why are the forms important?

The formula combines eight essential B vitamins plus choline in their active or readily used forms where appropriate. Methylated folate (5-MTHF) and methylcobalamin are included so the body can use those nutrients without extra metabolic conversion. The capsule also supplies balanced amounts of the other B vitamins to complement cellular processes.

• Active folate as 5-MTHF for direct usability
• Vitamin B12 as methylcobalamin for immediate biochemical support
• Complete set: B1, B2, B3, B5, B6, B12, folate, biotin plus choline
• One capsule format for convenient daily intake

How might I fit THORNE B-Complex #12 into my daily routine?

Take one capsule per day with water, ideally with a meal to improve absorption of water-soluble nutrients and to reduce any stomach sensitivity. The single-capsule dosing makes it easy to include with breakfast or another regular meal. Always follow label directions or your practitioner’s guidance.

• Simple one-capsule daily dosing
• Best taken with food for comfort and absorption
• Compatible with multivitamin stacks or targeted supplement plans

What quality assurances and testing does THORNE provide?

This product is third-party tested to confirm the contents match the label, giving independent verification of potency and purity. THORNE also emphasizes professional-level manufacturing standards and transparency about ingredient forms. The brand’s professional endorsements reflect widespread practitioner use.

• Third-party content verification
• Clear labeling of active, methylated nutrient forms
• Produced by a brand used by professional teams and clinicians

Are there practical safety or compatibility considerations?

Because B vitamins are water-soluble, they are generally eliminated when consumed in excess, but you should still follow recommended dosing and consult a healthcare provider if pregnant, nursing, or taking prescription medications. If you have specific genetic or medical conditions that affect methylation, mention the methylated forms to your practitioner to ensure they fit your needs. Store in a cool, dry place and keep capsules away from children.

• Follow the recommended one-capsule daily dose
• Consult a clinician when pregnant, nursing, or medicated
• Store properly and keep out of reach of children
