Immunity Boosters - Natural Coronavirus Cure or Scam? [Evidence Based]

How to boost the immune system? Do immunity boosters work to fight COVID-19?

This is the question everyone is asking and the internet is full of claims that almost everything can be immunity boosters.

The FDA even send warning letters to those promoting fake coronavirus cures.

But in reality, the idea of immunity boosters is a quite controversial topic amongst doctors and scientists.

However, one thing is certain – no immunity boosters, supplements or diet can prevent or cure coronavirus.

Currently, there is no scientific evidence that any supplement, natural or alternative treatment can reduce the severity of COVID-19.

The good news? There are lifestyle changes you can make to protect yourself and support your health.

Do immunity boosters work at all?

The truth is, you can’t boost an immune system that is already healthy. So, in that sense, most immunity boosters are useless.

What you can do, is support your immune system if you have deficiencies.

The most common vitamin deficiency that also happens to affect the immune system is that of vitamin D.

Studies suggest that the vitamin has a significant role in supporting and regulating the immune system. ¹ ² ³

Evidence has also revealed that vitamin D deficiency affects almost 50% of the world’s population. ⁴ ⁵

The latest meta-analysis of 25 RCTs with a total of 11 321 participants showed supplementation reduced the risk of respiratory infections in people deficient in it. ⁶

Not enough zinc might also cripple your immune system ⁷ ⁸, and almost 30% of elderly people are considered deficient in it. ⁹

Supplementation with zinc has shown benefits for conditions such as the common cold and lower respiratory tract infections. ¹⁰ ¹¹ ¹² ¹³

An in vitro study found that increasing the amount of zinc inside cells can stop the replication of the coronavirus. ¹⁴

Are there foods that boost the immune system?

Neither vitamin D nor Zinc supplementation has shown any benefits against COVID-19.

This is why it is enough to prevent their deficiency with a proper diet, instead of using supplements.

The ketogenic diet is a great weight-loss diet that will also support your immune system with foods rich in vitamin D, zinc and other essential nutrients.

Remember that these are not foods to boost the immune system but to support it and prevent deficiencies.

One of the best keto foods rich in vitamin D is cold-water fatty fish like salmon and mackerel.

Not to mention all the healthy omega 3 that they pack on as well. You should consume them daily or at least every other day.

A source of both zinc and vitamin D is another keto-friendly food – eggs. If you are worried about the cholesterol in them, make sure to check our article on [link to the keto diet and cholesterol].

The alkaline-keto diet is also rich in cruciferous vegetables that will support your body with all the vitamin C you need for an optimal immune system function.

What can help you against the coronavirus aside from immunity boosters?

The two most important lifestyle changes that everyone talks about are social distancing and good hand hygiene.

Do not neglect them, because these are the only ways you can prevent infection with COVID-19.

Another thing to do it get out of the high-risk zone.
As you might have heard, severe cases of COVID-19 are much more common amongst people with chronic conditions.

Surprisingly hypertension and diabetes show a stronger association with complications rather than chronic pulmonary diseases or immune problems.

A retrospective study in Wuhan revealed that hypertension is a comorbidity in 30% of hospitalized coronavirus patients. ¹⁵

Furthermore, the highest death rate is amongst people with cardiovascular diseases. ¹⁶

Some studies suggest that obesity might also be a predictor of increased health risk from the infection. ¹⁷

Controlling your blood sugar will also reduce the risks of bacterial pneumonia which is a common complication amongst critical COVID-19 patients. ¹⁸

Now might be a great time to take action and make the necessary lifestyle changes that can improve your glycemic and blood pressure control.

Because there is still no coronavirus cure, improving your overall health and managing comorbidities is the best thing you can do.

The importance of a good diet

If you are in the high-risk group, you need a diet that:

Allows for good blood sugar control
Helps you lower blood pressure
Grants quick weight loss
Has enough protein to support your immune system
Has enough vegetables to support optimal health with vitamins, minerals, and fiber

The best tool for a quick but healthy weight loss might be the ketogenic-alkaline diet.

Randomized studies reveal that you can lose weight faster with a low-carb diet when compared to other alternatives. ¹⁹

At the same time, you won’t be deprived of protein which is important for your immune function.

During the infection, body temperature and catabolic processes in the organism increase.

This raises the demands of the immune system for proteins, from which specific antibodies are synthesized. ²⁰

Furthermore, restricting your carbohydrate intake allows for a strict blood sugar control.

According to randomized trials, published in the journal of “Nutrition and Metabolism”, the keto diet can even reverse prediabetes and early diabetes, ²¹ ²²

Remember that not every keto diet is the same because many of them neglect the intake of unprocessed foods, vegetables, and fiber, so keto-alkaline is the better option.

If you are looking for a healthy keto diet, then check out the Keto Life program.

It’s a keto-alkaline diet focused on whole foods with plenty of protein, healthy fats, vitamins, electrolytes, and fiber.

The take-home message

While correcting some deficiencies might support your immune system, there are no effective immunity boosters if it is already healthy.

On the other hand, you shouldn’t neglect lifestyle factors that affect your health such as your diet, sleep, stress levels, exercising and unhealthy habits (smoking and alcohol).

Following a proper diet such as the ketogenic diet can help you control your blood pressure and diabetes, which are also the top risk factors for severe COVID-19.

So with all this said, I highly recommend that you check out Laura’s Keto Life program, where you’ll find the best keto-alkaline diet for weight-loss and health improvement.
