Analysis

The capsule supplies 20 mg of pyridoxine hydrochloride with 30 mg of olive leaf extract standardized to oleuropein. The B6 amount is meaningful without reaching the extreme levels found in many standalone products.

No active P-5-P or riboflavin cofactor is listed. The supplied ingredient data also does not show zinc despite the product name, so buyers should verify the current label before purchase.

One-capsule dosing and favorable value make it practical for focused use. People seeking only vitamin B6 may prefer a simpler active-form product without the botanical extra.

Who is it for
  • Adults seeking a moderate B6 amount
  • People interested in added olive leaf extract
  • Users who prefer once-daily capsules
Best for
  • Focused B6 intake
  • Moderate-dose supplementation
  • Simple daily use

Pros

  • Useful 20 mg B6 amount
  • One-capsule serving
  • Favorable value

Cons

  • Uses pyridoxine rather than P-5-P
  • No riboflavin cofactor
  • Supplied data does not list zinc

Warnings

  • Verify the current label because the supplied actives do not show zinc
  • Olive leaf extract may add blood-pressure-lowering effects when combined with antihypertensive medication
  • Count the 20 mg B6 amount when stacking other supplements

Nutrient quality

63 Moderate impact

A targeted vitamin B6 amount provides the clearest active contribution. The missing namesake zinc and small olive leaf amount make the formula poorly aligned with its apparent purpose.

.

Ingredient transparency

80 Highest impact

All listed active amounts are clear and no proprietary blend hides a dose. Inactive ingredients and complete daily-use directions are not supplied.

.

Customer satisfaction

60 Moderate impact

The supplied aggregate rating is strong. The very small review count provides limited rating confidence.

.

Value for money

62 Moderate impact

A low serving cost provides basic affordability. The missing namesake nutrient and lightly dosed olive leaf weaken formula value.
