Hey Everyone!

Today we’re going to cover the top two minerals linked to longevity. We’ll also look at how taking too much of certain minerals can actually deplete others and create new deficiencies.

In this clinical study here, researchers examined the trace mineral levels in healthy Chinese individuals who were over 100 years old — true centenarians. Using hair analysis, they measured minerals like chromium, selenium, zinc, iron, copper, and several others.

The most interesting part? Out of all the minerals tested, only zinc and copper were found to be within the normal range. Every other trace mineral was either too high or too low. That’s a powerful clue.

Why might this suggest that zinc and copper play a useful role in healthy aging and longevity?

Zinc and copper being in the normal range implies that the body is tightly regulating them, even at extreme old age. This homeostatic balance hints at their critical importance—the body seems to "prioritize" keeping them stable, unlike other minerals that drifted outside the normal range.

This kind of mineral stability is known as homeostasis—the body's ability to keep essential elements within a tight, healthy range. And when the body works this hard to maintain balance, it’s often a sign that those nutrients are vital for survival and long-term health.

Both zinc and copper are deeply involved in the body’s longevity machinery.

For starters, together they form a critical antioxidant enzyme called Superoxide Dismutase (SOD)—an enzyme we’ve talked about before that plays a major role in neutralizing free radicals and reducing oxidative stress, two key drivers of aging. When SOD is strong, cellular aging slows down. That’s already a major longevity win.

But that’s just the beginning.

Zinc plays a crucial role in the aging process, being involved in over 2,000 enzymatic functions, including those responsible for DNA synthesis and repair. Since aging is largely driven by the accumulation of DNA damage, zinc's contribution to cellular repair makes it absolutely vital for long-term health. It also helps prevent the buildup of amyloid plaque, which is closely associated with Alzheimer’s and dementia.

Shockingly, over 2 billion people worldwide are deficient in zinc, which may be one of the reasons we’re seeing such an explosion in neurodegenerative diseases. Between 2000 and 2010, Alzheimer’s cases rose by 68%, and currently, one out of every three people in America dies with Alzheimer’s Disease.

Zinc also plays a huge role in maintaining a strong immune system, which naturally declines as we age. A healthy immune response not only fights off infections, but also keeps cancer and other age-related diseases in check. On top of that, zinc provides powerful antioxidant and anti-inflammatory support, helping to reduce the low-grade chronic inflammation known as "inflammaging." It even helps protect the liver against toxic damage over time, helping defend this vital detox organ from chemical damage over time.

Copper, like zinc, is also essential for healthy aging and acts as a cofactor in a wide range of enzymes involved in everything from tissue repair to energy production. It plays a central role in neurotransmitter synthesis, which is critical for brain function, and copper deficiency is closely linked to cognitive decline and neurodegeneration.

Copper also helps form collagen and maintain the elasticity of connective tissues, including skin, joints, and blood vessels. Without adequate copper, issues like joint pain, ligament weakness, and vascular problems can start to develop. It’s also necessary for red blood cell production and proper iron metabolism—low copper can lead to anemia, even if iron intake is sufficient. At the cellular level, copper supports mitochondrial energy production, meaning it fuels the vitality of virtually every system in the body.

Together, zinc and copper are not only essential for daily function—they’re also foundational for long-term health and resilience. Their role in enzyme function, tissue maintenance, brain protection, immune strength, and oxidative stress management make them two of the most important trace minerals when it comes to healthy aging and longevity.

While ensuring adequate intake of these two minerals may help support similar aging processes, here’s where it gets even more interesting—zinc and copper are deeply interdependent.

High levels of zinc can suppress copper absorption by increasing the production of a protein called metallothionein in the intestinal cells. This protein binds to copper more tightly than to zinc, trapping the copper in the gut lining and preventing it from entering the bloodstream. As a result, excess zinc can lead to copper deficiency. But the relationship works both ways. Zinc and copper share common absorption pathways, which means high levels of copper can also compete with and suppress zinc absorption. This two-way competition is why maintaining a proper zinc-to-copper ratio is so critical—when either one becomes too dominant, it can disrupt the absorption and balance of the other, potentially leading to deficiency over time.

The fact that both were found to be in balance in centenarians suggests that it’s not just their individual levels that are critical—getting enough of each is essential—but also that their ratio may be equally vital for healthy aging. In other words, maintaining that delicate equilibrium may be just as important as avoiding deficiency. When one is too high or too low, it can throw the other off and disrupt this longevity-supporting synergy.

What makes this so astonishing is that zinc and copper aren’t just supporting players in the body—they're central regulators of systems that directly determine how fast or slow we age. They’re gatekeepers of oxidative stress, inflammation, DNA integrity, mitochondrial energy, and even brain preservation — including preventing harmful amyloid plaque buildup. And because they work through enzyme pathways that affect virtually every tissue and organ, their influence reaches every corner of the body. It's no coincidence that the only two minerals tightly regulated in people living over 100 were the ones responsible for controlling the very processes that allow us to survive that long in the first place. When these two are optimized—and in balance—they become a kind of molecular longevity code the body works hard to protect.

So many people today are mineral-deficient due to how depleted our soils have become. Zinc is a prime example — over 2 billion people worldwide are estimated to be deficient.

The first step is simply making sure we’re getting enough of these key longevity minerals. The next step is ensuring we’re getting them in the right ratios. Eidon’s Ionic Zinc and Copper — fully dissolved, electrically charged, and absorbed into the bloodstream almost instantly — are an ideal way to meet your needs in a highly bioavailable and balanced form.

According to the FDA’s Recommended Daily Values (DV) for adults on a 2,000-calorie diet, the daily requirement is 11 mg of zinc and 0.9 mg (900 mcg) of copper. The ideal zinc-to-copper intake ratio is around 10:1, with a healthy range between 8:1 and 12:1. However, the acceptable range is 5:1 to 15:1. Ratios beyond 15:1 — especially when maintained long-term — are often associated with symptoms of copper deficiency, such as fatigue, anemia, or neurological issues.

Here’s how Eidon’s minerals stack up:

If you take the recommended dosage (30 drops) of Eidon’s Ionic Zinc and Copper, you get:

Zinc: 7.5 mg
Copper: 0.6 mg

FDA Recommended Daily Value:

Zinc: 11 mg
Copper: 0.9 mg

At that 30-drop dosage, you’re getting a large share of your daily needs while also achieving a solid zinc-to-copper ratio — about 12:1. That’s within the healthy range. But if you want to fine-tune things for an even more optimal balance — like I do — you can bring it to a perfect 10:1 ratio by taking 30 drops of zinc and 38 drops of copper.

That brings you to:

Zinc (30 drops): 7.5 mg
Copper (38 drops): 0.76 mg

This ideal 10:1 dose provides a generous portion of your daily zinc and copper needs (though not the full 100%), while at the same time promoting a perfectly balanced zinc-copper ratio essential for healthy aging. It’s intentionally designed to flex with dietary variations—delivering over two-thirds of your daily value, but purposefully staying under 100%, to maintain the optimal 10:1 balance. For most people on a reasonably good diet, this combo will solidify a stable healthy zinc-copper balance, reinforcing one of the most important mineral dynamics for long-term health and vitality.

While this Zinc to Copper ratio seems to be the most important as seen in that longevity study, there are many other examples where taking too much of a particular mineral can deplete another mineral. For example, a couple widely known mineral imbalances that can occur are calcium to magnesium and sodium to potassium. In the PS. section of this newsletter after my signature just below, I go into great detail of the main 25 mineral imbalances that you want to look out for.

In that list below of 25 mineral imbalances, there are a small handful that directly involve zinc or copper, such as zinc and copper’s influence on manganese uptake. At the gentle, nutritional dosages we’re recommending—30 drops of zinc (7.5 mg) and 38 drops of copper (0.76 mg)—these imbalances are very unlikely to occur. The amounts are well below the upper tolerable limits and stay within physiologically safe, food-like ranges. They’re substantial enough to meet a large portion of your daily needs in the perfect ratios, but gentle enough not to tip the scales in any one direction.

And with Eidon’s minerals being fully dissolved, electrically charged, and designed for near-instant absorption into the bloodstream, you’re far less likely to overwhelm absorption pathways or trigger competitive interactions — especially compared to harder-to-absorb forms like oxides or carbonates, which can linger in the gut and compete more aggressively. This is the beauty of properly dosed, perfectly ratioed, highly absorbable minerals: they work with your body’s natural checks and balances — not against them.

The study of Chinese centenarians underscores just how crucial zinc and copper are as true longevity minerals. Their bodies maintain these minerals within a remarkably tight balance, suggesting the body prioritizes their stability above all else. This delicate equilibrium supports vital processes like antioxidant defense, DNA repair, immune resilience, and the prevention of amyloid plaque buildup — all key to healthy aging. By focusing on both adequate intake and proper ratios of zinc and copper, we’re not only addressing deficiency but also aligning with the natural mineral harmony observed in those who age successfully. With this foundation, it makes perfect sense to consider supplementing with high-quality, well-absorbed minerals to help maintain this balance.

PS. While the zinc-to-copper ratio may be one of the most important for longevity, it’s far from the only mineral balance that matters. In many cases, taking too much of a particular mineral can throw others out of balance and lead to unintended deficiencies. To help you navigate this, the next section breaks down the main 25 key mineral interactions that can impact your health. I know that this can get a bit maddening, but with a basic understanding of these dynamics, you’ll be better equipped to fine-tune your intake and support long-term balance, resilience, and vitality.
