Most people assume that taking a multivitamin is enough to cover all their nutritional bases. Pop one pill a day and you’re protected, right? Unfortunately, it’s not that simple. Even with a balanced diet and daily supplements, many people still experience what nutritionists call nutrient gaps or nutrient deficiency, the difference between what your body actually needs and what it gets.

These gaps are surprisingly common, and they can have a real impact on your energy, mood, skin, and long-term health. More importantly, they highlight a simple truth: the average multivitamin might not be up to the task of protecting you from nutrient deficiency in today’s world.

This is where smarter supplementation comes in.

What Are Nutrient Gaps?

A nutrient gap is exactly what it sounds like: a consistent shortfall in the vitamins, minerals, or bioactive compounds your body relies on to function optimally. It doesn’t necessarily mean you’re deficient to the point of illness, but it does mean your body is running on less than it could.

Some of the most common nutrient gaps in a modern diet include:

• Vitamin D: Low levels are widespread due to limited sun exposure.
  
  

• Magnesium: Up to half of people in developed countries don’t get enough, which can affect sleep, energy, and stress resilience.
  
  

• Omega-3 fatty acids: Essential for brain and heart health, but under-consumed in many modern diets.
  
  

• B vitamins: Crucial for metabolism and energy, yet easily depleted by stress, alcohol, and processed foods.
  
  

Left unchecked, these gaps can contribute to fatigue, brain fog, poor immune defence, and accelerated aging.

Why the Modern Diet Falls Short

If nutrient deficiency is so common, the next question is: why?

The modern diet, even when it looks “healthy,” often falls short in key ways. Processed foods are stripped of nutrients. Soil depletion has lowered the vitamin and mineral content of fruits and vegetables compared to decades ago. Busy lifestyles lead people to skip meals, eat on the go, or rely on convenience foods that are high in calories but low in micronutrients.

Even those who eat well can still miss important compounds. Nutrients like polyphenols, antioxidants, and NAD⁺ precursors aren’t always present in meaningful amounts in the average diet. That means the very compounds that protect your cells and slow down aging often never make it to your plate.

This is the foundation of modern nutrient deficiency: not always a dramatic lack, but a steady under-supply that undermines health over time.

The Bioavailability Problem

Let’s say you do take a daily multivitamin. The next hurdle is bioavailability - how well your body actually absorbs and uses the nutrients.

Not all nutrient forms are equal. Magnesium oxide, for example, is common in cheap supplements but is poorly absorbed compared to magnesium glycinate. Calcium and iron can compete with each other, blocking absorption. Gut health, stress, aging, and even medications can further reduce nutrient uptake.

This means that even if you’re “taking enough” on paper, your body may still not be getting what it needs in practice. Bioavailability is the difference between ticking a box and actually fuelling your cells.

Why Your Multivitamin Might Not Be Enough

Multivitamins were designed to be a broad safety net. But today’s demands, like longer lifespans, chronic stress, and an environment full of oxidative stressors, require more than the basics.

Here’s why your standard multivitamin often falls short and when you might need a multivitamin replacement:

1. Low-quality forms: Cheap, less bioavailable forms of minerals and vitamins that your body can’t fully use.
   
   

2. Generic dosing: Broad coverage, but often at doses too small to make a meaningful impact.
   
   

3. Missing key compounds: Most multis don’t include emerging longevity molecules like NMN, urolithin A, or spermidine, which support cellular repair and healthy aging.
   
   

4. One-size-fits-all approach: They rarely account for how nutrients interact with each other, or how individual lifestyles create unique nutrient needs.
   
   

The result: multivitamins help cover the basics, but they don’t fully address the deeper needs of a modern, high-performing body.

Hidden Signs of Nutrient Gaps

The trouble with nutrient deficiency is that it rarely announces itself in dramatic ways. Instead, it advances slowly, with symptoms that are easy to dismiss as “normal” parts of life:

• Energy crashes in the afternoon: Often linked to low magnesium or B-vitamin intake.
  
  

• Poor sleep: Nutrients like magnesium, zinc, and tryptophan support sleep quality.
  
  

• Mood changes and irritability: B vitamins and omega-3s are vital for brain chemistry.
  
  

• Skin changes: Low vitamin C, collagen precursors, and antioxidants can leave skin looking dull.
  
  

• Frequent colds: A sign that your immune system isn’t getting all the resources it needs.
  
  

Many people live with these low-grade symptoms for years, never realising they may be signs of nutrient deficiency rather than just “getting older” or “being busy.”

Who’s Most at Risk?

Some groups are especially prone to nutrient deficiency:

• Older adults: Aging reduces nutrient absorption and increases the body’s need for repair compounds.
  
  

• Vegetarians and vegans: Plant-based diets can fall short in B12, iron, and omega-3.
  
  

• Busy professionals: Stress depletes B vitamins and magnesium while raising demands on the nervous system.
  
  

• Athletes and active individuals: Exercise boosts nutrient requirements for energy, repair, and recovery.
  
  

This is another reason why “one-size-fits-all” multivitamins often miss the mark: different people have very different nutritional needs.

How Tmrw Helps Close the Gaps

That’s why we created Tmrw: not another multivitamin, but a true upgrade. Instead of repeating the “one pill fits all” formula, Tmrw is designed to bridge the gaps a modern diet leaves behind.

Here’s how:

• Magnesium Glycinate: Instead of poorly absorbed magnesium oxide, Tmrw includes this bioavailable form to support sleep, stress balance, and muscle recovery.
  
  

• NMN + CoQ10: Together, they replenish NAD+ and fuel mitochondrial performance, targeting the cellular energy gap that traditional multivitamins don’t touch.
  
  

• Urolithin A: Helps clear out damaged mitochondria and maintain muscle health, especially important as you age.
  
  

• Spermidine: Supports autophagy, the body’s process of renewing and recycling cells.
  

• Rhodiola Rosea + L-Theanine: Adaptogens that help the brain adapt to stress and improve focus, key areas where standard multis fall silent.
  
  

• Apigenin: Potent plant-based antioxidant that complements vitamins C and E, giving broader protection against oxidative stress.
  
  

• B-complex vitamins: Delivered in active forms that your body can use immediately to support energy metabolism and stress resilience.

• And more

The result is a product that doesn’t just check off micronutrient boxes but fills the real nutrient gaps of modern life - energy, resilience, focus, and long-term cellular health.
