Swanson Super Stress B-Complex with Vitamin C brings together a broad spectrum of B vitamins — including thiamin (B1), riboflavin (B2), niacin (as niacinamide), B6, folic acid, B12, biotin, and pantothenic acid — alongside 500 mg of vitamin C per capsule. Choline and inositol round out the formula, making this one of the more comprehensive capsule-format B-complex supplements available. The 240-capsule pack is produced by Swanson, a US-based supplement brand with a long-standing reputation for quality manufacturing standards.
Each capsule delivers high-potency levels across the B-vitamin range, with notable amounts such as 125 mg pantothenic acid, 125 µg vitamin B12 (as cyanocobalamin), 25 mg each of thiamin, riboflavin, and B6, and 200 µg folic acid. The vitamin C is provided as ascorbic acid.
This supplement is well suited to those who prefer a single daily capsule covering both the full B-vitamin spectrum and vitamin C together — particularly those following demanding schedules, plant-based diets, or anyone looking to consolidate their vitamin intake into one straightforward product.
