leaderboard Score 72.0
A competitively priced, high-potency B-complex with good amounts of co-factors, but uses less bioavailable B vitamin forms.
This B-complex from Natural Factors aims to provide comprehensive B vitamin support, with most B vitamins dosed at the 100mg level, similar to other 'B-100' products. It includes additional beneficial compounds such as PABA, Inositol, and Choline at solid dosages, with a notable 300mcg of Biotin. However, like many standard B-complexes, it uses less bioavailable forms for B12 (Cyanocobalamin), B6 (Pyridoxine Hydrochloride), and Folate (likely Folic Acid). This could potentially limit its efficacy for individuals with certain genetic predispositions or impaired conversion pathways. The price per serving is quite competitive, making it an attractive option for budget-conscious consumers seeking a potent B-complex.
- Excellent price per serving for a B-100 complex.
- High dosages of most B vitamins, supporting overall energy and metabolism.
- Good amounts of supportive nutrients like PABA, Inositol, and Choline.
- Higher Biotin content (300mcg) than some comparable B-complexes.
- Uses less bioavailable forms of B12 (Cyanocobalamin) and B6 (Pyridoxine Hydrochloride).
- Likely uses Folic Acid instead of the more active L-5-Methyltetrahydrofolate for folate.
- Contains Dicalcium Phosphate and Calcium Pantothenate as forms of calcium, which might contribute to excess calcium intake for some.
- High doses of B vitamins can cause bright yellow urine.
- Niacinamide is generally non-flushing, but individual sensitivities vary.
- Always consult a healthcare professional, especially if pregnant, nursing, or on medication.
