What’s inside this formula?
Thorne’s B-Complex #12 is listed here in the b-complex collection. This article looks at the selected 60 capsules · 60 servings pack, then puts its ingredients into context.
One capsule provides 600 mcg methylcobalamin B12, 667 mcg DFE folate and 23.4 mg total B6 across two forms.
Check the original label ↗A B-complex combines several vitamins with different jobs and different amounts. Some help release energy from food; others contribute to blood-cell formation or nerve function. The label deserves a vitamin-by-vitamin reading because a convenient combination can also duplicate nutrients already present in a multivitamin.
The pack details above come from the manufacturer. Ingredient research below does not establish the effects of this exact product or independently verify its contents.
B12 is only part of the comparison
The 600 mcg B12 amount is methylcobalamin; folate is 667 mcg DFE as L-5-MTHF. One capsule is a serving. Compare all B vitamins instead of choosing only by the largest headline number.
Read both ingredient forms
The panel separates B6 into 20 mg pyridoxine HCl and 3.4 mg pyridoxal-5-phosphate. B2 is 25 mg riboflavin plus 3.6 mg riboflavin-5-phosphate sodium. Other amounts are B1 40 mg, niacinamide 80 mg, B5 45 mg, biotin 80 mcg and choline 14 mg.
Vegan does not mean suitable for everyone
Thorne labels the complete product vegan. Its B6 exceeds EFSA’s adult limit at one capsule; prolonged excess can harm nerves. The folate component needs medication review, particularly during methotrexate cancer therapy. No superior clinical outcome is established by this label comparison.
Where might it be useful?
Energy metabolism
Several B vitamins help the body use energy from food; they do not supply extra calories or act as a universal stimulant.
Filling specific gaps
A suitable combination can contribute nutrients that are genuinely missing from a person’s diet.
What the research can — and cannot — tell us
The B-complex name does not define a standard formulation. Evidence for one nutrient or deficiency cannot establish that every combination improves energy, stress or concentration. Compare B6, niacin, folate and B12 separately, including their amounts in other products.
What deserves your attention?
The 23.4 mg B6 per capsule exceeds EFSA’s 12 mg/day adult upper limit; avoid unnecessary long-term stacking. Thorne flags folate with methotrexate cancer therapy.
Suitability comes before strength
Excessive B6 can damage nerves, while some niacin forms cause flushing. Tell clinicians about added biotin before laboratory tests, and review long-term high-strength combinations carefully.
