Nature's Way, B-100 Complex, 100 Capsules

What it's for

Cellular energy metabolism, nerve health, nutrient metabolism, general wellness

Who it may fit

Adults with busy schedules who want daily B vitamin support for energy metabolism, or people with limited dietary variety seeking a high potency B complex.

Key actives per serving

• Thiamine (as thiamine HCl): 100 mg (8333% DV)
• Riboflavin (vitamin B2, as riboflavin 5'-phosphate): 100 mg (7692% DV)
• Niacin (as niacinamide): 100 mg (625% DV)
• Vitamin B6 (as pyridoxine HCl, pyridoxal-5-phosphate): 50 mg (2941% DV)
• Folate (400 mcg folic acid providing 666 mcg DFE): 666 mcg DFE (400 mcg folic acid) (167% DV)

How to take

Adults take 1 capsule once daily, preferably with food; B complex supplements are often better tolerated with a meal.

Diet / Allergen fit

Gluten-free. No wheat, dairy, or artificial colours or flavours.

Thiamine (as thiamine HCl)

Thiamine is converted to thiamine pyrophosphate which acts as a coenzyme for carbohydrate metabolism and energy production in cells.

Caution: High-dose B vitamins may cause mild stomach upset in some people; taking with food may improve tolerance.

Riboflavin (vitamin B2, as riboflavin 5'-phosphate)

Riboflavin forms the coenzymes FAD and FMN that help enzymes produce cellular energy and manage redox reactions.

Caution: Bright yellow urine can occur with riboflavin and is harmless; take with food if sensitive.

Niacin (as niacinamide)

Niacinamide supports enzymes involved in energy metabolism by forming the coenzymes NAD and NADP.

Caution: Niacinamide usually avoids flushing, but high doses may cause digestive discomfort; take with food to reduce irritation.

Vitamin B6 (as pyridoxine HCl, pyridoxal-5-phosphate)

Vitamin B6 forms pyridoxal-5-phosphate which helps enzymes in amino acid metabolism and neurotransmitter synthesis.

Caution: Very high intakes over time may be linked with nerve tingling; follow label directions.

Folate (400 mcg folic acid providing 666 mcg DFE)

Folate supports one‑carbon metabolism for DNA synthesis and methylation processes.

Caution: Folic acid may mask low vitamin B12 status; those with limited B12 intake should be mindful.

How they work together

Core B vitamins supply coenzymes that drive carbohydrate, fat and protein metabolism to produce cellular energy. Thiamine, riboflavin, niacinamide and pantothenic acid feed key steps of the energy pathways, while B6 and folate support amino acid processing and methylation, with B12 completing methylation cycles.
