What is the clinical dose for Cranberry + Astragalus + Nettle?

Clinical trials typically use Cranberry: 500mg/day for UTI prevention; Astragalus: 500-2000mg/day; Nettle: 300-600mg/day. Sunergetic Kidney Cleanse Cranberry delivers 2 capsules daily; 30 servings per bottle; multi-botanical blend, which we classify as Blend relative to that range.

How does Sunergetic Kidney Cleanse Cranberry compare to similar Capsule?

See the "Also consider" section below for two alternatives. Choose based on form preference (Capsule vs alternatives), dose adequacy, and third-party testing.

Is Sunergetic Kidney Cleanse Cranberry third-party tested?

Yes — GMP manufactured; third-party testing not publicly disclosed. Third-party testing verifies ingredient identity and label accuracy.

Does this work with Amazon Subscribe & Save?

Yes — Amazon Subscribe & Save is available for this product. Enrolling locks in a recurring delivery at a reduced per-unit price.

Are there any potential interactions with medications?

Astragalus can affect immune function and may interact with immunosuppressants (cyclosporine, tacrolimus). Nettle has mild diuretic and blood pressure lowering effects — monitor if on antihypertensive medications or lithium. Cranberry may enhance warfarin effects — consult your doctor if on anticoagulation. Inform your physician if you have any kidney disease before starting.

Are there any side effects from long-term use?

Cranberry, astragalus, and nettle have centuries of traditional use and favorable human trial safety profiles. Long-term daily use is generally well tolerated. Astragalus has been studied for 6+ months in clinical trials. Annual kidney function blood tests (BUN, creatinine, eGFR) are reasonable with chronic urinary supplementation.

Does it cause any digestive issues or side effects?

Generally well tolerated. Cranberry extract can occasionally cause mild stomach upset — taking with food helps. Nettle is gentle on digestion. Astragalus may cause mild stomach cramps at higher doses. Stay well hydrated to support kidney filtration and minimize any tract irritation.

Can it be taken with other supplements or vitamins?

Pairs well with magnesium, Vitamin C (supports urinary acidification), and D-mannose for enhanced UTI prevention. Avoid stacking with other diuretic supplements to prevent electrolyte imbalance. Do not combine with prescription diuretics without physician oversight.

Are there any specific instructions for taking it safely?

Take 2 capsules daily with water and a meal. Drink plenty of additional water throughout the day — adequate hydration is the foundation of kidney and urinary health. Monitor for any urinary tract symptoms (burning, urgency) and consult a doctor if they occur. Do not use as substitute for prescribed kidney therapy.

How long until benefits are typically experienced?

UTI prevention effects from cranberry typically emerge after 2-4 weeks of daily use. Kidney function support is cumulative over 2-3 months. Diuretic effects from nettle may be felt within days. Overall urinary health benefits build over 4-12 weeks with consistent daily supplementation.
