Arginine – The Simple Supplement That Could Help Boost Immune Function

Arginine

Arginine does more than help build proteins — your cells also need this amino acid to produce immune-alert proteins that help T cells recognize infected or abnormal cells.

When arginine became scarce, the cellular machinery responsible for building these immune-alert proteins stalled, leaving fewer warning signals available to help the immune system detect threats.

In mice, increasing dietary arginine reduced colon tumor formation and improved outcomes in influenza and SARS-CoV-2 infections, benefits that disappeared when researchers disabled the immune pathway arginine supports, confirming the effect wasn’t coincidental.

Whole foods are the preferred starting point for maintaining healthy arginine intake, with grass fed beef, lamb and watermelon providing options without relying automatically on supplements.

Adequate protein, sufficient carbohydrates and lower linoleic acid intake support the broader cellular environment your immune system needs to produce energy, build proteins and respond effectively to threats.

Erythritol

In a laboratory study, erythritol disrupted several functions in cultured human brain blood vessel cells, raising concerns that its effects extend beyond blood sugar and calorie content.

Erythritol increased oxidative stress while reducing nitric oxide production by about 20%, interfering with a key process that helps your blood vessels relax and regulate blood flow.

The sweetener increased production of endothelin-1, which promotes blood vessel constriction, by about 30%, further shifting the balance away from healthy blood vessel function.

Erythritol-treated cells failed to activate their normal clot-clearing response when researchers exposed them to a clotting signal, suggesting another way the sweetener could interfere with healthy brain blood vessel function.

Avoiding erythritol starts with checking ingredient lists — it appears in many products not obviously marketed as sugar-free — and choosing natural sweeteners like ripe fruit, raw honey or maple syrup in moderation rather than replacing it with another artificial substitute.

Why Tolerate Medical Fraud?

The documentary You Can See Everything opened over the weekend. It is about Elizabeth Holmes and her company Theranos, and how it grew to a $9B valuation by 2014 without a reliable product. It was a vibe-based company, one that Wall Street wanted to exist: a compelling female founder, Ivy dropout, a digital innovation to disrupt the establishment, all at a time of zero interest rates and a desperate hunt for high returns.

To what extent is she personally culpable, or was she merely scapegoated by an angry mob of investors? The film does not fully answer that question, even if it leaves one with a sense of confusion as to why she languishes in federal prison.

In the backdrop of all of this is the biggest medical fraud in modern history. The Covid lockdowns wrecked every nation that tried them – have a look at France today – and the shots that followed created carnage that is still not openly discussed in any mainstream media. Our pair of books called Cries for Help https://www.amazon.com/dp/B0HM57V61Y document thousands of injuries and deaths for which no one is being held to account.

And these products are still on the market. Until last week, the Covid shots were still being pushed by the CDC on pregnant women even if we have mountains of data on elevated miscarriage rates. It’s mind-boggling that this happened and is still happening.

The loss of trust is pervasive and well earned. Brownstone’s poll last spring documented supermajority support for medical freedom: no mandates, no lies, no coercion, no more corruption. You are not alone, even if the mainstream media, reliant on pharma funding, reports none of it.
