It’s becoming commonplace to see the corruption of the FDA and other 3-letter government agencies intended to be public health protectors.

N-Acetyl-Cysteine (NAC)

I never understood why the FDA threatened the removal of NAC during COVID-19. NAC supplementation has been used to support Chronic Obstructive Pulmonary Disease (COPD) symptoms and lung decline. One study showed that 600 mg of NAC (2x a day) significantly improved lung function symptoms of COPD. Chronic bronchitis can also benefit from NAC. Maybe the lung-related benefits made the FDA try to ban NAC so that we’d turn to the COVID-19 vaccine. Still, I didn’t have “proof.”

Well, a 2021 cohort study shared how N-acetyl-cysteine reduced the risk for mechanical ventilation and mortality in patients with COVID-19 pneumonia.

The study found that oral NAC administration of 1200 mg/d in patients with COVID-19 pneumonia reduced mechanical ventilation and death risk. How come the hospitals never used NAC and only relied on Remdesivir? Even the World Health Organization (WHO) is not a fan of Remdesivir.


In 2022, the FDA declared that NAC is not a legal dietary supplement. You can find the latest FDA update here.

It’s strange because NAC supports the immune system and is a precursor for glutathione, the master antioxidant in the body. NAC also helps to relieve symptoms of respiratory conditions. NAC can act as an antioxidant and expectorant, loosening mucus in the airways.

NAC may prevent free radical damage and reduce oxidative stress and chronic inflammation (one adverse, downstream effect of the COVID-19 vaccine).

If you need NAC, we have discounted the Pure Encapsulations brand here. You would have to take 3 capsules daily to take the dose from both studies above.



Desiccated Thyroid Extract (DTE)

Something similar is going on in the compounding pharmacy world with DTE. The FDA has declared desiccated thyroid extract as a biological drug and is no longer eligible for compounding. Natural desiccated thyroid is a thyroid hormone replacement medication derived from pig’s thyroid glands. The main two products in the US are Armour Thyroid and NP Thyroid.

In late 2022, the FDA designated NDT/DTE a biological drug, meaning that each manufacturer must go through a Biologics License Application to sell the drug. If the manufacturers don’t obtain approval, Armour and NP Thyroid will no longer be on the market.

While there are still a few years until this goes into effect, it’s more important than ever to get to the root cause of healing. We never know when the fickle FDA will get rid of very much-needed supplements and “alternative” supports.

FDA Corruption

I decided to do some FDA corruption research and didn’t have to look too far.

study by Science Magazine tracked 107 FDA advisors and found that 62% received money from drug makers in four years. Twenty-five percent received over $100,000, and six percent received over $1 million. 


In 2009, Pfizer and Johnson & Johnson paid $2.3 billion for fraudulent marketing. The U.S. Justice Department announced it as the “largest health care fraud settlement in history.” Then in 2013, J&J paid another $2.2 billion. Yet, just seven years later, we trusted these same companies with emergency use authorization for COVID-19 experimental drugs.

In 2014, Pfizer paid $325 million for defrauding insurers. And if you haven’t heard, in 2021, J&J was fined $2.1 billion for asbestos in its talc baby powder. Yet you can still purchase the powder almost anywhere.


Why do we trust these companies that have fraud and corruption in their very recent history?


PS. I didn’t bring up Bayer, but Bayer has been fined nearly $11 billion for glyphosate and RoundUp cancer claims. The company has committed to removing glyphosate from Roundup by 2023. I’m not holding my breath— they can play mad chemist and switch one toxic molecule for another. I dedicated a whole chapter on glyphosate in Carnivore Cure and how muscle meat can be protective because of the aromatic amino acids (even animals that eat crops bred with glyphosate use).


Take care of your body. Eat meat and limit processed foods. Work to strengthen the body so that you don’t have to rely on medications that can be taken away by the (corrupt) FDA and (blatantly corrupt) pharmaceutical companies.


If you haven’t read my COVID-19 article on vaccines, you can find it here, and the “alternative” supports we used when we had COVID-19, here. If you get the annual flu shot, I highly recommend reading my research on the efficacy of the flu shot.
