Micros vs. Macros: What’s the Difference and Why You Need Both for Optimal Health

Fact-Checked By a Nutritionist MD

Published on June 31,2025

If you’ve ever tried to improve your diet, count calories, or start a fitness plan, chances are you’ve heard the term macros. But there’s another category of nutrients that’s just as critical—if not more so—for your long-term health: micronutrients.

In this guide, we’ll break down the difference between macronutrients vs. micronutrients, what each one does in your body, and how to make sure you’re getting enough of both—whether through food, supplementation, or functional support like GRNS.

What Are Macronutrients?

Macronutrients are the nutrients your body needs in large amounts to function properly and produce energy. They include:

1. Carbohydrates

Your body’s primary energy source. Found in: fruit, vegetables, grains, legumes. Broken down into glucose to fuel your brain, muscles, and cells

2. Protein

Essential for muscle repair, immune function, and enzymes. Found in: meat, eggs, dairy, tofu, legumes, seeds. Made of amino acids that build tissue and support hormones

3. Fats

Crucial for hormone production, brain health, and cell structure. Found in: nuts, seeds, olive oil, avocado, fatty fish. Help with absorption of fat-soluble vitamins (A, D, E, K) Some nutritionists also include water and fibre as important macronutrients because they’re needed in large quantities for digestion and hydration..

🧬 What Are Micronutrients?

Micronutrients, on the other hand, are the vitamins and minerals your body needs in smaller amounts—but their impact is massive.

They don’t provide calories or energy directly, but they enable every biochemical process in your body to function properly, from metabolism to immune health and beyond.

Key Micronutrients Include:

Vitamins: A, B-complex, C, D, E, K

Minerals: Iron, magnesium, zinc, iodine, calcium, selenium

Trace Elements: Copper, manganese, chromium, molybdenum

These nutrients are found in a variety of whole foods—especially fruits, vegetables, whole grains, and lean proteins. However, modern diets often fall short, which is why micronutrient deficiencies are surprisingly common even in developed countries.

Macros vs. Micros: Key Differences

You need both macros and micros working in sync. For example, your body can’t convert food into energy (a macro process) without micronutrient cofactors like B-vitamins and magnesium.

🚨 What Happens When You’re Deficient?

If You’re Low on Macros

- Weight loss (or gain if excess)

- Fatigue, brain fog, poor recovery

- Blood sugar crashes or energy dips

If You’re Low on Micros

- Weak immune function

- Hormonal issues or mood swings

- Poor sleep, low energy, slow metabolism

- Hair loss, brittle nails, skin issues

How GRNS Supports Your Micro Intake 🌿

GRNS is not a meal replacement or macronutrient source—it’s a micronutrient powerhouse designed to complement your diet by providing a diverse range of:

✅ Vitamins & minerals from real food (leafy greens, berries, herbs)

✅ Phytonutrients for antioxidant and anti-inflammatory support

✅ Adaptogens to support hormonal and stress balance

✅ Prebiotics & probiotics to enhance nutrient absorption

Whether your macros are dialed in or not, GRNS fills in the micronutrient gaps with wholefood-based nutrition, helping you feel more energised, focused, and resilient.

Balancing Both in Real Life ✅

Here’s how to start prioritizing both macros and micros in your daily routine:

🌈 Eat the rainbow: Include a wide variety of colourful fruits and vegetables to get different vitamins and minerals

🥩 Don’t fear protein or fat: Quality sources are key for hormone production and repair

🧃 Supplement smartly: Use GRNS to support daily micro intake—especially on busy days

🥣 Avoid ultra-processed foods: They’re often high in calories (macros) but low in nutrients (micros)

🌿 FAQ: Macros, Micros & GRNS

1. Can you be hitting your macros but still be unhealthy?
Absolutely. You might be eating enough calories, protein, carbs, and fat—but still lacking vital micronutrients, especially if you’re relying on processed foods or skipping vegetables.

2. Does GRNS replace meals or protein shakes?
No, GRNS doesn’t provide a substantial amount macronutrients like protein or carbs. It’s designed to supplement your micronutrient intake and help cover nutritional gaps.

3. Can I take GRNS if I already eat a healthy diet?
Yes—modern farming practices and busy lifestyles make it hard to get enough nutrients from food alone. GRNS is great insurance for even the healthiest eaters.

4. How do I know if I’m deficient in micronutrients?
Common signs include fatigue, low immunity, mood issues, poor skin or hair, and sleep problems. A blood test can confirm specific deficiencies, but supporting your body daily with micronutrients is a safe place to start.

5. Are there macros in GRNS?
GRNS contains trace amounts of macronutrients (like fibre and protein from plants), but its main purpose is to deliver vitamins, minerals, phytonutrients, and digestive support, not calories or bulk fuel.
