You eat clean. You prioritize whole, nutrient-dense foods and avoid processed junk. By all accounts, you’re doing everything right. You’ve also probably heard that: “If you’re eating well, you don’t need supplements.”
It sounds reasonable - until you start digging deeper.
Because despite all the kale, quinoa, and clean proteins, many health-minded people are still running low on crucial nutrients. The reason? Our modern food system and lifestyle have changed more than we realize, and the old rules about nutrition don’t fully apply anymore.
In this article, we’ll explore why even the cleanest diet might be leaving you nutritionally vulnerable, and why key supplements (like a well-formulated multivitamin and certain overlooked nutrients) could be the missing link in your wellness journey.
Our Food Isn’t What It Used to Be
The truth is, the food we eat today isn’t as nutrient-dense as it was just a few generations ago. While our modern diets may seem healthy on the surface, they’re still missing critical elements due to several systemic changes in how food is grown, stored, and distributed.
Soil Depletion:
Soil depletion is a major reason why the food we eat today isn’t as nutrient-packed as it used to be. Thanks to industrial farming practices like overusing synthetic fertilizers and relying on monocropping, our soil has been stripped of essential minerals. As a result, the crops we depend on now often provide far fewer vitamins and minerals than they did just a few decades ago. Research published in the National Institutes of Health, highlights how the decline in soil health (meaning the loss of its natural structure, nutrient content, and ability to support beneficial microbes) is directly tied to the drop in food quality. Even if you're filling your plate with colorful veggies and organic produce, the nutritional payoff just isn't what it once was. Despite our best efforts to eat clean, many of us are still missing out on crucial nutrients due to these environmental shifts, which is why strategic supplementation has become less of a luxury and more of a necessity for long-term health.
Food Shipping and Handling:
The journey our food takes from farm to table has never been longer. With much of our produce traveling hundreds, even thousands, of miles, nutrients naturally begin to degrade over time. This is particularly true for foods with longer shelf lives or those shipped over vast distances. Research has shown that the prolonged time between harvest and consumption, along with fluctuating storage and transportation temperatures, significantly reduces the nutritional content of many fruits and vegetables.
Additionally, how we store and process food also impacts its nutrient levels. Freezing, canning, and microwaving all contribute to nutrient loss. Freezing vegetables, for instance, can cause a loss of water-soluble vitamins like vitamin C and B vitamins, while canning leads to the destruction of heat-sensitive compounds like beta-carotene.
In short, our food is simply not as nutrient-dense as it once was. As a result, even the healthiest diets today may still leave us lacking the essential nutrients our bodies need for optimal health. Remember that your best chance at getting the most nutrient-dense food is to grow it yourself or choose local, organic foods that are fresh (harvested recently).
Our Bodies Aren’t Operating the Same, Either
It's not just our food that's changed—our bodies are dealing with a different set of challenges too. Poor gut health is one of the biggest culprits.
Poor Gut Health
Our microbiome plays a critical role in breaking down complex food molecules, synthesizing and absorbing nutrients. This is especially true with vitamins like K2, certain B vitamins, and even the conversion of vitamin K1 to K2. When gut health is compromised, whether due to an imbalanced diet, gut dysbiosis, stress, or environmental factors, our ability to absorb these vital nutrients diminishes.
Chronic Stress
In these modern times, everyone seems to be under chronic stress. It feels inescapable sometimes, but chronic stress can seriously impact our nutrient reserves. Chronic stress depletes our body’s stores of vitamin C, the B vitamins, and magnesium, all of which are essential for a variety of bodily functions, from immune health to energy production. When we’re constantly on edge, these nutrients get burned up faster than we can replenish them.
Medications
Let’s not forget about medications. Americans are on more medication than ever before and unfortunately, some of the most common drugs like antibiotics, proton pump inhibitors (PPIs), statins, and others, can strip the body of crucial nutrients. Antibiotics, for example, may kill off beneficial gut bacteria that help us breakdown food and absorb nutrients, while statins can interfere with the body’s ability to produce CoQ10, a powerful antioxidant.
With all these factors working against us, it’s no wonder our bodies aren't operating the way they should. So even if you’re eating clean, the odds are high that you’re still missing out on some critical nutrients.
Multivitamins Are Now a Necessity, No Longer a Suggestion
In today’s world, even the most mindful eaters can fall short on essential nutrients. Soil depletion, busy schedules, an unhealthy microbiome, and food supply chain issues have made diet gaps a very real concern, even for those following a clean, whole-foods lifestyle. That’s why multivitamins have shifted from being a casual “extra” to a practical necessity.
But not all multivitamins are created equal.
When choosing a quality multi, look beyond the flashy labels. Here’s what really matters:
Bioavailable forms: Look for nutrients your body can actually absorb and use, like methylated B vitamins (such as methylfolate and methylcobalamin) and whole-foods sourced mirconutrients from plants.
Complete coverage: A good multi should include often-overlooked nutrients like Vitamin K2, iodine, and molybdenum—not just the basics.
Clean ingredients: Avoid formulas with unnecessary fillers, artificial dyes, and synthetic preservatives that can burden the body more than they help.
Clinical dosages: Some multivitamins sprinkle in tiny amounts of trendy nutrients just to claim them on the label. Prioritize products that provide therapeutic amounts backed by science, not just marketing.
Why is Vitamin K2 suddenly a Thing?
When we talk about bone health, heart health, and even dental health, one critical nutrient often goes unnoticed: Vitamin K2. Unlike its more famous cousin, Vitamin K1 (known for its role in blood clotting), K2 acts as a traffic director, making sure calcium gets deposited where we want it (in bones and teeth) and not where we don’t (like arteries and kidneys).
So why are we so deficient in K2 today?
The answer is twofold. First, our modern diets are severely lacking in foods naturally rich in K2. Traditionally, it was abundant in grass-fed animal fats, aged cheeses, and fermented foods like natto (items that most people rarely eat today) so there didn't used to be a concern about K2 deficiency. Second, a poor gut microbiome further complicates the problem. While a healthy gut can convert some Vitamin K1 into K2, damage from processed foods, antibiotics, and stress can severely impair this natural conversion process.
The risks of deficiency are serious.
Without enough K2, calcium can end up in all the wrong places. This misplacement has been linked to conditions like osteoporosis, arterial calcification (a major contributor to heart disease), and dental issues such as cavities and weakened enamel.
What’s the best way to supplement?
For optimal benefits, Vitamin K2 in the form of MK-7 is the top choice. This form not only has a longer half-life in the body (meaning it stays active longer), but it's also better absorbed compared to other forms like MK-4. For anyone looking to protect their bones, teeth, and arteries, making sure you’re getting enough K2 (especially in the right form) can be a game changer.
Make Sure You're Including Vitamin D3
If your multivitamin doesn't contain Vitamin D, you may want to consider adding one. Vitamin D deficiency isn’t just common—it’s a growing public health issue. According to a study published in Nutrition Research, approximately 41.6% of U.S. adults are vitamin D deficient, with even higher rates among certain groups like African Americans (82.1%) and Hispanics (69.2%).
And that data is already over a decade old-trends suggest it has only worsened with more indoor living, increased screen time, and overuse of sunblock.
Why is this such a big deal? Vitamin D isn’t just a "bone health" vitamin; it acts more like a hormone, influencing over 2,000 genes in the body. Low levels have been linked to a wide range of serious health concerns, including:
- Weakened immune function: People with low vitamin D are more vulnerable to infections and autoimmune conditions.
- Increased risk of osteoporosis and fractures: Vitamin D is crucial for calcium absorption and bone strength.
- Higher rates of mood disorders: Research has linked low vitamin D levels with depression and seasonal affective disorder (SAD) and other studies have shown that supplementation may be helpful.
- Cardiovascular health issues: Deficiency has been associated with hypertension, heart disease, and increased risk of stroke.
Magnesium: The Most Underrated Mineral
Magnesium is one of the most underrated nutrients, yet it plays a role in over 300 enzymatic reactions in the body. From energy production to muscle function, brain health to blood sugar regulation, this essential mineral does it all. And yet, most people aren’t getting nearly enough.
Low magnesium has been linked to issues like anxiety, insomnia, fatigue, migraines, high blood pressure, and even poor insulin sensitivity. According to emerging research, it may also help reduce inflammation, support detoxification, and ease symptoms of PMS and mood swings.
Modern soil depletion, processed foods, and chronic stress all contribute to widespread deficiency. Supplementing with a highly bioavailable form like magnesium glycinate or malate can be a game-changer for how you feel, sleep, and function.

The Final Takeaway
Living a healthy lifestyle—eating whole foods, getting regular movement, managing stress—is still absolutely essential. But in today’s world, it’s no longer enough on its own.
Modern life has created gaps we can't always fill through diet and habits alone. From depleted soils to indoor living to increased environmental toxins, we face challenges our ancestors never had to think about.
That’s where smart, targeted supplementation comes in. By intentionally supporting your body with the right nutrients in the right forms, you can not just survive—but truly thrive—even in a world that's increasingly out of sync with our natural needs.
It’s not about chasing trends. It’s about giving your body the foundational tools it requires to do what it was designed to do: heal, regenerate, and flourish.
