Certifications from organizations like NSF International, USP (United States Pharmacopeia), or ConsumerLab can be good indicators of quality.

7. Manufacturer Information: Reputable manufacturers often provide more information about their sourcing, extraction methods, and quality control processes. Look for brands that are transparent about where and how their stinging nettle is sourced and processed.

8. Allergen Information: Check for any allergen warnings on the label, especially if you have known allergies. Some supplements may be processed in facilities that handle common allergens like nuts, dairy, or gluten.

9. Expiration Date: Ensure the supplement has a clear expiration date. This helps you confirm the product’s freshness and efficacy.

10. Certifications and Seals: Certifications such as organic, non-GMO, vegan, gluten-free, or kosher can provide additional assurance of the product's quality and suitability for specific dietary needs.

In summary, when selecting a stinging nettle supplement, look for labels that provide information on standardization, source and purity, the part of the plant used, dosage and potency, additives and fillers, third-party testing, manufacturer transparency, allergen information, expiration date, and relevant certifications. These factors collectively ensure that you are choosing a high-quality supplement that is both effective and safe.
