Frequently Asked Questions
Are capsules better than powder?
Neither format is automatically better. Convenience, dose transparency, formulation and quality matter more than format alone.
What should a fisetin capsule label show?
At minimum, the fisetin amount per serving, serving size, other ingredients and required regulatory labeling for the market where it is sold.
Do more capsules mean a stronger product?
No. Compare milligrams per serving and formulation, not capsule count.
What should I verify before buying this type of fisetin product?
Confirm the exact fisetin amount, serving size, other ingredients, seller identity, testing information and warnings.
Does 'third-party tested' always mean the same thing?
No. Look for details about what was tested, by whom and whether the documentation matches the product or batch.
Is the highest purity percentage automatically the best product?
No. Purity is useful, but identity, contamination controls, formulation and appropriate use also matter.
Should I compare price per bottle or per serving?
Price per serving and per stated active amount are generally more useful than bottle price alone.
Are marketplace ratings enough to verify quality?
No. Reviews can describe user experience but do not replace product documentation or analytical testing.
What label claims are red flags?
Be cautious with guaranteed anti-aging, disease-treatment, cartilage-regeneration or 'removes zombie cells' promises.
Can a delivery technology justify a higher price?
Only if the formulation, evidence and quality information provide a credible reason for the premium.
