Analysis

The one-tablet serving supplies vitamin C and every core B vitamin at clearly stated amounts. Thiamine is high, while the remaining nutrients are positioned for broad maintenance rather than an extreme high-potency profile.

No chemical forms are identified for the B vitamins. That omission makes it impossible to confirm whether folate, B12, or B6 use active or conventional sources.

A 2 mg B6 amount is appropriate for ongoing use and avoids the concern created by many B-50 products. The large package offers strong practical value for users satisfied with basic form transparency.

Who is it for
  • Adults wanting long-term basic B coverage
  • Bulk-buyers focused on value
  • Users who prefer moderate vitamin B6
Best for
  • Everyday B-complex maintenance
  • Energy-metabolism nutrient coverage
  • Low-cost single-tablet use

Pros

  • Provides the full B-vitamin family
  • Adds 150 mg of vitamin C
  • Uses a moderate B6 amount
  • Requires one tablet per serving

Cons

  • Does not disclose vitamin forms
  • Contains no meaningful choline
  • Offers no active-form assurance
  • Large thiamine amount is unnecessary for most users

Vitamin B5 · 5.5 mgRiboflavin · 20 mgThiamin · 100 mgVitamin B12 · 15 mcg

B vitamins directly support carbohydrate metabolism and cellular energy production. Their essential metabolic roles are well established, especially when correcting inadequate intake.

Thiamine is high-potency, while riboflavin is moderate and vitamin B12 falls below the preferred target. Exact amounts are clear, but the chemical forms are not disclosed.

Report overview
Niacin · 25 mg OverallScore74
B+ Active Ingredient Quality & BioavailabilityC- Dose, Safety & Label TransparencyA+ Value

A 25 mg dose fits a B-complex, but the unspecified niacin form limits goal-specific assessment. The label lists niacin without naming its chemical form, limiting predictions about flush risk and goal fit. Value is especially strong for a broad B-complex with a practical niacin amount.

View ingredientView products
Thiamin · 100 mg OverallScore68
F Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyA+ Value

The clearly disclosed dose is well suited to high-potency thiamine use. Its unnamed chemical form leaves an important uncertainty about absorption quality, while the tablet format is conventional. The large supply combines a substantial dose with especially low serving cost.

View ingredientView products
Riboflavin · 20 mg OverallScore42
F Active Ingredient Quality & BioavailabilityC Dose, Safety & Label TransparencyC Value

The low maintenance dose may cover basic intake but offers less metabolic support than higher-potency options. The chemical form is not disclosed, and the tablet may release more slowly than a capsule or liquid. Very low serving cost and a large supply partly offset these formulation limits.

B-Complex with Rice Bran

NaturesPlus Source of Life Garden
