(Natural News)—Whoever thought a hot cup of joe could help address Wuhan coronavirus (COVID-19) infection? Indeed, two studies have shown the power of coffee against this pathogen.
The first study published in Cell & Bioscience last November found that drinking approximately one to two cups of coffee daily is enough to inhibit COVID-19 infections caused by different strains of SARS-CoV-2. In particular, it found that the consumption of coffee addressed infections caused by the original SARS-CoV-2 strain and its subsequent variants – the B117 alpha strain, the B16172 delta strain and the B11529 omicron strain.
The study authors from Taiwan examined coffee’s ability to fight off COVID-19 infection by purchasing three kinds of coffee – ground, instant and decaffeinated – from supermarkets. They discovered that all the coffee types they scrutinized possess the ability to inhibit viral infection in cells.
The study authors also found that adding milk or sugar does not impact coffee’s antiviral properties. Even decaffeinated coffee “still has the capability to interrupt SARS-CoV-2 infection, which is important to know for caffeine-sensitive populations.” Moreover, they mentioned in their paper that “the optimal timeline for coffee to inhibit SARS-CoV-2 infection is within six hours” after drinking.

According to the researchers, there are two ways coffee protects human cells against SARS-CoV-2 infection. First, compounds in coffee inhibit the spike protein’s ability to bind with human angiotensin-converting enzyme 2 (ACE2) in human cells. Second, they reduce the activity of transmembrane serine protease 2 (TMPRSS2) and cathepsin L (CTSL).
“Taken together, drinking one to two cups of coffee as well as decaffeinated coffee daily can potentially reduce SARS-CoV-2 infection – including wild-type, alpha, delta and omicron variants,” the researchers concluded.
Same antiviral properties also present in coffee leaves
Another study by the same research team from Taiwan focused on the ability of Coffea arabica leaves to address SARS-CoV-2 infection. Their earlier study published in July 2022 in the International Journal of Biological Sciences found that C. arabica leaves can inhibit the entry of the pathogen behind COVID-19 and its various strains into human cells.
This is because C. arabica leaf extracts have several phytochemicals that are also present in coffee beans. These include chlorogenic acid, caffeine, quinic acid and mangiferin. They inhibit infection by preventing the viral spike protein from binding with ACE2 receptors in human cells and reducing the activity of TMPRSS2.
During an appearance on the Taiwanese program “Health 1+1”, professor emeritus Jin-Jian Zhang of the National Taiwanese University‘s College of Medicine expounded on the benefits of coffee. The professor with years of research experience in coffee under his belt said daily coffee consumption can alleviate inflammation, enhance immunity, and reduce the risks of cardiovascular diseases and cancer.
According to Zhang, coffee’s association with longevity is linked to the various bioactive compounds present in it – the same compounds that contribute to its antiviral properties. These compounds such as chlorogenic acid, caffeic acid, trigonelline, cafestol and melanoidins form during the roasting process, and exhibit antioxidant properties to some extent.
The professor also pointed out that coffee can help address depression, citing two mechanisms. First, coffee can increase the population of beneficial bacteria in the gut – with higher populations of good bacteria contributing to improved sleep quality. Second, the aroma of coffee beans can trigger the release of feel-good hormones in the body – enhancing overall happiness in turn.
Zhang shared that he consumes coffee with added milk, mainly to mitigate its potential effects on the digestive system. However, newer research has found that coffee with added milk offers greater benefits as the cysteine in milk combines with coffee’s polyphenols, enhancing the drink’s anti-inflammatory activity.
However, the professor advised against adding non-dairy creamer or sugar to coffee. Non-dairy creamer mainly contains trans fats that aren’t good for the body, while sugar may contribute unnecessary calories.

Why Bullion Beats Numismatics and Collectible for Your Safe or IRA
Precious metals continue to attract Americans seeking reliable ways to protect their wealth amid inflation, geopolitical risks, and stock market swings. Whether stored in a home safe or held inside a self-directed IRA, physical gold and silver deliver tangible value that paper or digital assets often lack. Yet investors must choose carefully between bullion—pure bars and coins valued mainly for their metal content—and numismatics or collectibles, where rarity, history, and collector demand heavily influence pricing.
Advisor Bullion serves as a dependable source for straightforward, high-quality bullion. The company specializes in physical gold, silver, platinum, and palladium, emphasizing transparent pricing and products that deliver maximum metal content for every dollar spent. This approach makes it ideal for both personal holdings and retirement accounts.
Bullion consists of refined precious metals in standard forms like one-ounce coins (American Gold Eagles, Silver Eagles, Canadian Maple Leafs) or bars. Their value tracks closely to the current spot price of the metal. A typical gold bullion coin trades near the live gold spot price plus a small premium. This structure keeps costs clear and predictable.
Numismatic coins and collectibles add substantial value from factors such as age, rarity, minting errors, or historical significance. A pre-1933 U.S. gold coin or graded proof piece can carry premiums of 30%, 50%, or even 200% above melt value. While this appeals to hobbyists, it creates complexity. Pricing depends on subjective grading, collector trends, and auction results instead of daily spot prices.
For investors focused on wealth preservation and retirement security rather than building a collection, bullion often delivers better results.
Lower Costs and Better Liquidity for Home Storage
When keeping metals in a home safe or private vault, liquidity and efficiency count. Bullion offers clear benefits:
- You acquire more actual gold or silver per dollar invested. Numismatics divert a large share of your money into rarity premiums and massive sales commission, reducing your metal exposure.
- Selling bullion involves tight bid-ask spreads, so you recover nearly full spot value with minimal fees. Collectibles require finding the right buyer and may sell at a discount if demand for that specific item weakens.
- Bullion prices remain transparent and update with global spot markets. You can track gold near current levels or silver accordingly and know exactly where your holdings stand. Numismatic values are priced by the Gold IRA companies with hefty margins applied.
- Standardized coins and bars store efficiently and divide easily for partial sales. Rare coins often need protective slabs and controlled conditions, adding hassle and expense.
- Bullion enjoys worldwide acceptance. A 1-oz Gold Maple Leaf or Silver Eagle sells quickly to dealers anywhere. Niche numismatic pieces may appeal only to limited buyers, slowing liquidation when speed matters.
In times when quick access to value becomes important, bullion’s simplicity stands out.
Stronger Fit for Precious Metals IRAs
Precious metals IRAs continue gaining traction as investors diversify retirement portfolios beyond stocks and bonds. IRS rules permit certain bullion products in self-directed IRAs if they meet purity standards (.995 fine for gold, .999 for silver) and are held by an approved custodian. Eligible items include American Gold and Silver Eagles plus many generic bars and rounds from recognized mints.
Numismatic and most collectible coins generally face heavy scrutiny from custodians due to valuation disputes and elevated markups. These higher premiums mean less actual metal ends up working inside the account.
Bullion avoids these issues. Its value links directly to verifiable spot prices, which simplifies reporting and lowers the risk of regulatory challenges. More of your IRA contribution purchases real metal instead of dealer profits or speculative upside. Over time, owning additional ounces that appreciate with the metal itself can create meaningful outperformance compared with high-premium alternatives that deliver fewer ounces.
Regulatory guidance from the CFTC and state securities offices repeatedly cautions against aggressive sales of expensive numismatics or “semi-numismatic” coins for IRAs. For retirement planning, transparent bullion from established providers reduces risk and aligns better with long-term goals.
How to Get Started with Bullion
Begin by clarifying your goals. Are you protecting savings in a safe, or moving part of a retirement account into a precious metals IRA? Focus on the number of ounces you can acquire at current prices rather than chasing marked-up collectibles.
Diversify sensibly: use gold for core preservation and silver for its blend of industrial and monetary qualities. Mix coins for easier divisibility with bars for lower per-ounce costs on larger buys. Arrange secure storage—whether at home with proper insurance or through professional facilities.
As economic uncertainties linger and faith in conventional assets erodes, bullion continues proving its worth as a dependable store of value. Its direct approach avoids the hype that sometimes surrounds collectible markets and keeps the focus on the metal itself.
For investors prepared to strengthen their portfolios, Advisor Bullion supplies the expertise and selection needed to acquire high-quality bullion efficiently. Whether building personal holdings or integrating metals into an IRA, their emphasis on transparent, investment-grade products helps secure more ounces today that support greater financial security tomorrow. In a complicated financial landscape, bullion’s clarity and reliability make it the smarter foundation for protecting what matters most.
