Frequently Asked Questions

Yes, absolutely. Every supplement we sell meets pharmaceutical-grade standards for purity, potency, and safety. This means our products are manufactured in GMP-certified facilities, undergo rigorous third-party testing for contaminants (heavy metals, pesticides, microbial impurities), and contain active ingredients at the labeled potency. We maintain certificates of analysis (COAs) for every batch — available upon request.

Many of our herbal formulas — including Liu Wei Di Huang Wan, Jia Wei Xiao Yao San, and Suan Zao Ren Tang — are made with USDA Certified Organic ingredients. We source from over 50 certified organic farms across the US. For products that are not fully certified, we ensure all botanical ingredients are grown without synthetic pesticides, herbicides, or GMOs, and we provide full transparency on sourcing.

Our traditional formulas (like Zi Su Ye, Liu Wei Di Huang Wan, An Shui Wan Teapills) are based on centuries-old Traditional Chinese Medicine (TCM) principles. They use specific combinations of herbs that work synergistically to support the body's natural balance. Standard supplements (like ProOmega, Carditone) are typically single-ingredient or isolated compounds backed by modern clinical research. Both categories meet our pharmaceutical-grade quality standards.

We use a multi-layered quality assurance process: (1) Raw ingredients are tested for identity, purity, and potency upon arrival. (2) Manufacturing follows strict GMP protocols. (3) Finished products undergo third-party laboratory testing to verify potency, dissolution, and shelf-life stability. (4) We store all products in climate-controlled facilities to maintain potency until delivery.

Dietary supplements are not FDA-approved in the same way as prescription drugs. However, our manufacturing facilities are FDA-registered and comply with current Good Manufacturing Practices (cGMP).

Yes, we strongly recommend consulting with a qualified healthcare provider before starting any new supplement regimen — especially if you are pregnant, nursing, taking prescription medications, or have a pre-existing medical condition. Our products are not intended to diagnose, treat, cure, or prevent any disease. Always read the label and follow the recommended dosage instructions.

While our products are generally well-tolerated, individual responses can vary. Some herbal formulas (like Jia Wei Xiao Yao San) may cause mild digestive upset in sensitive individuals. We recommend starting with the lowest recommended dose and monitoring your body's response. If you experience any adverse effects, discontinue use and consult your healthcare provider. Detailed ingredient lists and contraindications are provided on each product page.

Most supplements should be stored in a cool, dry place away from direct sunlight (below 77°F / 25°C).

Check the product label for specific storage instructions.

Many of our products are gluten-free, dairy-free, and soy-free. Please check the product description or supplement facts panel for specific allergen information.
