The Best Quercetin Supplements

1. Mt. Angel Vitamins – Quercetin Nettle+

Mt. Angel Vitamins - Quercetin Nettle+ review

Mt. Angel Vitamins – Quercetin Nettle+

The Mt. Angel Vitamins – Quercetin Nettle+ offers you a natural histamine release. It supports your immune system and fights allergies by inhibiting the manufacturing process and release of histamines into your body. With less histamine production, you get less inflammation and allergy attacks. This translates to less swollen sniffly noses!

With this supplement, you get a powerhouse of ingredients ready to help your immune system. Vitamin C, pantothenic acid (vitamin D3), magnesium, quercetin, bromelain, and stinging nettle leaf all make for a strong, active supplement ready to reduce allergy symptoms like sinus and nasal discomfort. Even better, the supplement only has a few all-natural inactive ingredients, including cellulose, organic rice extract, and organic rice concentrate. Despite the other ingredients, you still get 1,000 mg of quercetin.

What you don’t get is soy, salt, yeast, gluten, milk, egg, sugar, starch, or preservatives. Just take three vegetarian tablets with or without food. A single bottle comes with a month’s supply. Also, the supplement is made in the USA in an FDA and CMP certified facility. All of this and the company tests heavily for potency and impurities like heavy metals, insecticides, and microbes. However, this option will cost you a little more than our favorite option but does come with a few added ingredients to help fight allergies.

Buying Guide for Quercetin Supplements

Find out everything you need to know about quercetin right here. Find out if it’s safe, the benefits, and the side effects. Get answers to your pertinent questions too.

Benefits of Quercetin

The main active ingredients sound great, but what benefits do they actually offer, and are they worth adding to your diet? Take a look:

Quercetin is the main ingredient in all of the supplements above and for good reason. The flavonoid is found in superfoods, and it provides tons of benefits. First, it can lower inflammation by fighting the natural process of oxidation that ages us, humans. Inflammation is the root of almost all diseases, including cancer, cognitive decline, autoimmune disorders, and even heart disease.

Second, quercetin fights allergies as it’s a natural antihistamine and anti-inflammatory. It can fight both seasonal and food allergies, along with asthma and skin reactions! We could stop here, but there are still more benefits.

Third, it supports heart health through lowered inflammation and oxidative stress. It can also fight pain associated with autoimmune conditions like arthritis and infections. Moreover, it can improve energy and endurance because it improves blood flow.

For all the same reasons listed above, quercetin fights cancer, protects skin health, protects the liver, and protects against neurological disorders. Finally, it can also control blood sugar, blood pressure, and protect your brain. Whew! It really is a power-food!

Other Ingredients

Bromelain is another potent substance, and its found in pineapple with more in the core than in the rest of the fruit. The enzyme is a natural remedy for indigestion and allergies. The other benefits include preventing cancer, treating digestive disorders, faster recovery from surgery and injuries, fights allergies and asthma, prevents and treats sinus infections, helps decrease joint pain, and can even help you lose weight.

Stinging Nettle Leaf boasts its own list of benefits, including fighting urinary and prostate issues, osteoarthritis and joint pain, hay fever, bleeding, and eczema. As you can see, all of these main ingredients focus on fighting allergies!

As for inactive ingredients, almost all supplements need some ingredients to stabilize the pills and act as flow agents. All the inactive ingredients in the products we chose are safe. Rest assured, we only chose high-quality supplements for our list.

Side Effects

Quercetin is naturally derived from food, which makes it safe for almost anyone. That’s right, all the benefits with very little risk. Most studies have found no side effects in those eating a nutrient-dense diet. However, high doses can have some side effects like headaches, stomach aches, and tingling in your arms and legs. Even higher doses (given intravenously) can damage the kidneys in rare cases.

You should talk to your doctor before taking if you are on medications as quercetin may interact with certain drugs and reduce the effectiveness of antibiotics, chemotherapy, and blood thinners. It’s considered safe for pregnant and breastfeeding mothers, but you should always check with your doctor before taking quercetin.

Questions About Quercetin Supplements

What foods naturally contain quercetin?

Quercetin can be found in many foods you probably eat often. You can find the flavonoid in vegetables like onions, peppers, capers, onions, shallots, asparagus, broccoli, kale, and red leaf lettuce. You can also find it in some fruits, including red apples, red grapes, cranberries, blueberries, raspberries, and citrus fruits. Also, both green and black tea contain quercetin.

Do note that organic food can contain dramatically higher doses of quercetin than commercially grown food, up to 79 percent more! If you can’t afford organic, definitely consider supplementing to get the most benefit for your allergies.

Is it possible to take too much quercetin?

Yes, it is possible, but only if you are taking it intravenously. If you are eating any of the foods above on a daily basis, then you probably don’t need to take a supplement. However, if you want to fight allergies, it’s totally safe to take a supplement on top of eating the food, especially if you can’t afford organic. It’s almost impossible to overdose on quercetin.

Should I try other antioxidants as well?

Too many antioxidants can cause problems. If you are eating a healthy diet and taking quercetin, you do not need to take more antioxidants unless you are taking them for a different ailment. Each antioxidant serves a different purpose, so do your research to find out which one will help you the most or try taking smaller doses of multiple antioxidants. Always speak with your doctor before taking a new supplement.

Conclusion

The best supplement to help you improve seasonal sinus and nasal problems is the Mt. Angel Vitamins – Quercetin Nettle +. While it’s designed to support healthy histamine levels, it offers enough quercetin to offer all the benefits of the powerful flavonoid. You get top ingredients from a quality brand and added benefits for more antioxidant support. You can improve your health and control allergies naturally.
