12 Best Quercetin Zinc Immune Support Supplements 2021
What Is Quercetin?
While the best way to get quercetin is through your diet, it also is available in supplement form, as pills or capsules. Sometimes, quercetin in supplement form is packaged with bromelain, an enzyme found in pineapples, because both have anti-inflammatory properties (Quercetin & Bromelain for inflammation). Most dietary supplements contain a chemical compound, aglycone, which is the free form of quercetin.
When looking for and using quercetin supplements, it’s important to maintain a nutritious, balanced diet with fiber and healthy fats in it, as research shows that accumulation of quercetin in the body is dependent on “factors such as glucose moieties, solubility, human factor, vitamin C status and food matrix.”
Specifically, research also says that quercetin supplementation is best achieved when consumed with a fat-enriched diet.
There are foods high in quercetin that you can add to your diet. Arguably, red onions are some of the most potent sources of quercetin; one study found that absorption of onion-derived quercetin was 52% compared to only 24% in supplement form. In fact, onions can give you three times the amount of quercetin than you’d get from apples. Other food sources that are high in quercetin include:
- Organically grown apples, grapes and tomatoes
- Dark cherries and dark berries like blueberries, blackberries and bilberries (eaten in moderation)
- Cocoa, unsweetened
- Hot green chili peppers
Benefits of QuercetinQuercetin has been linked to the following health benefits:
- Possessing anti-inflammatory, antioxidant properties that can help combat certain diseases. One study found that 500 mg of quercetin a day could improve symptoms of rheumatoid arthritis.
- Helping prevent cancer cell growth from breast, colon, prostate, endometrial and lung.
- Counteracting allergic reactions and helping with immune responses.
- Helping to prevent osteoporosis
- Addressing cognitive decline, including Alzheimer’s and dementia.
- Assisting in control of blood pressure. A study in 2002 found that quercetin can have vasodilator effects.
- Potentially helping to lower blood sugar levels. One study found that dosages of 500 mg per day “significantly reduced” fasting glucose levels.
- Gargle mouthwash: 2 x daily – gargle (do not swallow) antiseptic mouthwash with cetylpyridinium chloride (e.g. Scope mouthwash™, Crest mouthwash, Colgate mouthwash) or povidone/iodine 1 % solution as alternative (e.g. Betadine® Antiseptic Sore Throat Gargle™).
- Chronic Prevention: 0.2 mg/kg per dose (take with or after a meal) — twice a week for as long as disease risk is elevated in your community
- Post COVID-19 Exposure Prevention: 0.4 mg/kg per dose (take with or after a meal) — one dose today, repeat after 48 hours
- Vitamin D3: 1000–3000 IU/day. (Amazon) (iHerb)
- Vitamin C: 500 - 1,000 mg BID (twice daily) (Amazon) (iHerb)
- Quercetin: 250 mg daily. (Amazon) (iHerb)
- Zinc: 30 - 40 mg/day (elemental zinc). Zinc lozenges are preferred. (Amazon) (iHerb)
- Melatonin: 6 mg before bedtime (causes drowsiness). (Amazon)
- High risk Individuals: > 60 years with co-morbidities (hypertension, diabetes, chronic lung disease, chronic kidney disease), obesity, long term care facilities, etc.
- Post COVID-19 exposure: To use if a household member is COVID-19 positive, or you have prolonged exposure to a COVID-19 positive patient without wearing a mask.
- Precautionary Note: Ivermectin has a number of potentially serious drug-drug interactions. Please check for potential drug interaction at Ivermectin Drug Interactions - Drugs.com. The most important drug interactions occur with cyclosporin, tacrolimus, anti-retroviral drugs, and certain anti-fungal drugs.
- Due to the possible drug interaction between quercetin and ivermectin (may increase ivermectin levels), these drugs should not be taken simultaneously (i.e. should be staggered morning and night).
- Ivermectin is also lipophilic and therefore, bioavailability is maximised on a full stomach; or best to be taken with meal.
- Vitamin D3 RDA (Recommended Daily Allowance) is 800–1000 IU/day. The safe upper-dose daily limit is likely < 4000 IU/day. Vitamin D deficiency has been associated with an increased risk of acquiring COVID-19 and from dying from the disease. Vitamin D supplementation may therefore prove to be an effective and cheap intervention to lessen the impact of this disease, particularly in vulnerable populations, i.e. the elderly and obese.
- When Is the Best Time to Take Vitamin D? Morning or Night? It is possible that increasing vitamin D levels during the day may act, in part, as a signal that suppresses melatonin generation (source). Therefore, it's better to take vitamin D (with meal) during the day and melatonin to be taken just before bedtime.
- It is likely that vitamin C and quercetin have synergistic prophylactic benefit. Quercetin should be used with caution in patients with hypothyroidism and TSH levels should be monitored.
- Please consult with a qualified doctor and only use human ivermectin. Ivermectin for animals contain excipients (binding and storage compounds such as polyethylene glycol (PEG)) that are known to cause liver failure in high doses.
EARLY TREATMENT PROTOCOL
1. First line agents (use any or all medicines; listed in order of priority/importance)

This is the best quercetin I found on the market! It was a revelation to me to discover that regular quercetin is difficult for the body to absorb. After doing my research I discovered that quercetin phytosome has much greater absorption and is therefore more effective. I have been taking this for over a month and my allergy symptoms have been reduced tremendously. In addition, this company added specific Whole Foods that contain the highest amount of added quercetin for additional quercetin benefits. Besides allergies I also take this for it’s high anti oxidants and many other health benefits. I love this brand and I will continue to buy their products.
