"I'd been concerned about my kidney health for months. Within a couple of weeks of taking ResorinÂŽ I felt less bloated, more comfortable, and my worrying eased. At 67, I finally feel in control of my health again."
Secret of Elderberry
One Berry. Four Powerful Compounds.
Elderberry Extract
1,200mg per serving of cold-extracted Sambucus nigra â one of the most studied botanicals for kidney and immune support, used for over 2,000 years in traditional medicine to support filtration and fluid balance.
Anthocyanins (C3G)
Elderberry's signature active compound, cyanidin-3-glucoside is the bioactive behind its kidney research â binding to glomerular capillaries, neutralizing oxidative stress, and supporting nephron repair at the cellular level.
Zinc Citrate
Naturally deficient in most CKD patients, zinc plays a critical role in kidney cell repair and immune regulation. Resorin uses zinc citrate â the most bioavailable form â to restore what CKD depletes.
Buffered Vitamin C
Standard vitamin C can stress compromised kidneys. Resorin uses a buffered form that delivers antioxidant protection and collagen synthesis support without the oxalate load that damages kidney tissue.

Expert Advice from Dr. Steven Chen, Integrative Medicine & Renal Health Specialist
âAs we age, one of the most overlooked factors in kidney health is the impact of oxidative stress on the bodyâs natural filtration pathways. These delicate systems are responsible for maintaining the balance between waste removal and keeping essential proteins in the bloodstream where they belong.
When oxidative stress and cellular strain begin to affect these pathways, filtration efficiency can gradually decline â often without obvious symptoms at first. Thatâs why supporting these systems early is so important.
A targeted combination of antioxidant support, like standardized elderberry, alongside key nutrients such as zinc and vitamin C, can help maintain healthy cellular function and support the bodyâs natural filtration processes.
Used consistently, this kind of daily support can play an important role in helping individuals maintain kidney function, support normal protein balance, and feel more confident in their long-term health.â

My eGFR went from 41 to 56 in 90 days.
I've been watching my eGFR decline for 4 years. My nephrologist told me to 'just monitor it.' I started ResorinÂŽ and at my next lab check my number had jumped 15 points. I cried in the parking lot.
The swelling in my ankles is finally gone.
I had to stop wearing my regular shoes because my ankles were so swollen by afternoon. Within 3 weeks of taking ResorinÂŽ every morning, the puffiness was noticeably better. My husband noticed before I did.
Part of my kidney routine now. Non-negotiable.
I take ResorinÂŽ every single morning with my other medications. My nephrologist has no objection and my last two lab results have been the most stable in years. I'm not stopping.
Subtle at first, but my labs tell the story.
The first month I wasn't sure. By month three my creatinine had dropped and my eGFR was up 11 points. I have more energy, less brain fog, and I sleep through the night. It works quietly but it works.
We're serious about clean health, ask away
Transparency matters when it comes to daily supplements. Below you'll find answers to the most common questions about our elderberry supplement
Take 2 capsules daily with food and water. For general maintenance and immune support, take 2 capsules once daily, preferably with breakfast or lunch. At the first signs of illness (sore throat, fatigue, etc.), you may take 2 capsules twice daily (morning and evening) for 3-7 days for acute support, then return to the maintenance dose. Do not exceed 4 capsules per day without consulting a healthcare professional.
Tonava can generally be taken alongside most vitamins and supplements. However, if you are taking:
- Immunosuppressant medications (e.g., for organ transplants or autoimmune conditions): consult your doctor, as elderberry may modulate immune function
- Diabetes medications: monitor blood sugar closely, as elderberry may improve insulin sensitivity
- Diuretics: elderberry has mild diuretic effects; consult your healthcare provider
- Blood thinners: vitamin C in high doses may interact; stay within recommended dosage
Always separate Tonava from tetracycline or quinolone antibiotics by at least 2 hours, as zinc can reduce their absorption
Resorin is generally well-tolerated with minimal side effects when taken as directed. Some users may experience mild digestive changes as their gut microbiome adjusts (this typically resolves within a few days). High doses of zinc (above the recommended amount) may cause nausea or metallic tasteâstick to the suggested 2-4 capsules per day. If you experience any unusual symptoms, discontinue use and consult a healthcare professional.
Many customers take Resorin alongside their medications without issues, but you should always consult your doctor first. Aged garlic is generally well-tolerated, but your healthcare provider needs to monitor your numbers as they may improve and require medication adjustments.
