Vitamin C, vitamin D, zinc – this is the golden triad we hear about pretty much every day as they are recommended both to boost immunity and reduce the severity of the symptoms in Covid patients. It’s pretty easy and straightforward to get in line with the recommendations. However, there are other supplements that are worth talking about during this troubled time. We just got to discover and read tons of studies about Bromelain, Quercetin, and Resveratrol. And they are all worthwhile if you want to boost immunity and even increase longevity. Let’s have a look at the details:


It’s extracted from pineapple but mostly from the stalk of the plant. The pineapple is a very popular tropical fruit that we can find nowadays pretty much everywhere in the world. The pineapple is rich in antioxidants, as well as fibers and enzymes that help digestion, reduce inflammation, and regulate intestinal transit. Pineapples are even recommended for people who want to lose weight because of their properties.

Bromelain is an enzyme extracted from the pineapple. It can ease digestion and help you get rid of inflammation, and these benefits have been clinically demonstrated. Bromelain can improve the amino acids absorption process, with a systemic impact in all metabolic processes where proteins are involved. Bromelain can help with muscle formation, joints recovery, skin cell renewals, and improve blood circulation. Studies show that taking bromelain supplements leads to an improvement in the skin aspect, mainly by reducing cellulite and swollen hands and feet. 

This enzyme can dissolve the internal scar tissue caused by inflammation in the body. Aside from calming the swollen area, it can also help the body recover after surgical interventions and other sickness. Studies also show that Bromelain can have a positive impact even on patients getting anti-cancer treatment. More than this, some research also demonstrated that Bromelain is antiviral and antibacterial, so it can be efficiently used to treat bronchitis and pneumonia and boost the immune system. And this makes it an ideal supplement for this period marked by the Coronavirus pandemic. 


This is a polyphenolic compound that can be found in nature in different fruit and vegetables. Quercetin is a bioflavonoid, a group of antioxidants that are also pigments. They fight free radicals and help the body on several levels. Among the effects of the quercetin, we’ll mention just a few:

– Anti-allergic effect;

– It can reduce the bad cholesterol in the blood;

– It can support the optimal function of the cardiovascular system;

– Anti-tumor action;

– Beneficial effects at the level of the eyes.

But we’re discussing quercetin now because it has been proven to have positive effects fighting Coronavirus. There are recent studies showing that quercetin can help keep the virus at bay. It has an inhibitory effect on this virus, acting against one of the key proteins that are essential for the virus multiplication. What happens is that quercetin blocks the enzymatic activity of the 3CLpro, hence having an inhibitory effect on the growth of the coronavirus, and can also lead to its destruction. 

Spinach, pears, red apples, kale, blueberries, onions, green chili pepper, and other fruits and veggies are good natural sources of quercetin. However, to make sure you get the daily recommended dose (500 to 1000 mg per day), you might want to get a quercetin supplement. 


Resveratrol is an antioxidant, also from the polyphenols category, and is often present in fruits with dark colors such as black grapes, blackberries, blueberries, raspberries, and others. Over the last half a century, multiple studies have demonstrated the antioxidant role of resveratrol and its effects on the body, from slowing down the aging process to protecting the heart, lungs brain, to improving the cognitive functions. 

Have you heard about the “French paradox”? It’s a study from the beginning of the ‘80s that aimed to discover how comes the French people have a low risk of death due to cardiovascular diseases despite their diet that is rich in fats and cholesterol. Other nations with a similar diet had a much higher risk of heart issues-related death. So, what did the French do differently that helped them live longer despite having bad habits such as smoking and a fat-rich diet? Well, the study showed a connection between the consumption of red wine (containing resveratrol) and a healthy cardiovascular system. 

Other more recent studies show that resveratrol not only has positive effects on the heart’s health, but it can also prevent cancer. Studies performed in the lab on mice showed a 15% increase in life expectancy for mice receiving 5 grams of resveratrol on a daily basis. 

Regarding lung health, resveratrol can act as an inhibitor to certain proteins that foster the occurrence of inflammation at the level of the pulmonary alveoli. Another study on mice shows a slowdown in the evolution of the cancer cells present at the level of the lungs. 

While the French seem to be doing just fine drinking red wine to reap all the immunity-boosting and longevity-increasing benefits of resveratrol, you might want to choose a natural supplement that can help you get the job done without the potential headaches.
