Quality & Materials

Natural source Griffonia extract. Contains some rice flour and stearic acid as flow agents, which is standard for this price tier.

Evidence & Testing

NOW is one of the few brands with an in-house lab capable of advanced mass spectrometry to ensure the absence of Peak X contaminants.

Brand Transparency

Strong transparency on manufacturing locations and quality control processes, though individual batch COAs are not always public.

Value Assessment

Unbeatable value at $0.17 per 100mg dose, making it the top choice for budget-conscious consumers.

Why Not Alternatives?

Cheaper 'bargain' brands often fail potency tests or lack third-party manufacturing certifications. NOW maintains high standards (UL/GMP) while keeping the price accessible.
