As a passionate, driven young athlete, you already know that training hard, sleeping well, and staying hydrated are nonnegotiables. But there’s another pillar that sometimes gets overlooked: nutrition at the micronutrient level — that is, vitamins, minerals, and the little nutrients that support everything your body is doing behind the scenes.

Here’s why they matter, and how to make sure you’re covered — plus a special offer for the MindFuel family at the end.

What Are Vitamins & Minerals—and Why Do You Need Them?

Think of your body as a high-performance machine. You take care to put in good fuel (carbs, proteins, fats), but you also need high-quality lubricants, spark plugs, and coolant — that’s what vitamins and minerals are doing.

• Vitamins (A, C, D, E, the B-complex, etc.) help with energy production, immune defense, growth, and tissue repair.
• Minerals (such as iron, calcium, magnesium, zinc, selenium) are involved in muscle contraction, nerve signaling, bone strength, oxygen transport, and preventing cramps.

When you're training hard, your body’s demand for certain vitamins and minerals goes up. If even one is deficient, your performance, recovery, or energy can suffer.

Common Nutrient Gaps for Female Athletes

Here are some nutrients that competitive female athletes—especially teens—should pay attention to:

• Iron: Teen girls (especially active ones) are vulnerable to low iron because of growth and menstrual cycles. Low iron can mean fatigue, weaker endurance, and lower oxygen delivery to muscles.
• Calcium & Vitamin D: Essential for bone health. Training stress and hormonal changes can put you at risk of bone injuries (stress fractures). Without enough, your body might draw calcium from bones.
• Magnesium: Helps with muscle relaxation and preventing cramping. Also supports sleep and recovery.
• B Vitamins: Crucial for converting food into energy. When you have high training loads, your need for B vitamins increases.
• Antioxidant vitamins (C, E, selenium, zinc): Help counter oxidative stress (free radicals) produced when you push your body hard.

Because teen bodies are still growing, your micronutrient needs are already high — adding intense training means you have to be extra careful about covering your bases.

Whole Foods + Smart Supplementation = Strongest Strategy

Ideally, you want to get most vitamins and minerals from whole foods:

• Fruits, vegetables, whole grains, nuts, seeds
• Lean proteins (chicken, fish, eggs, beans)
• Dairy or fortified non-dairy (for calcium, vitamin D)
• Iron-rich foods (red meat, spinach, legumes)

But in real life, with training, school, travel, and everything else on your plate, it can be tough to meet all your micronutrient needs daily. That’s where safe, certified supplements can help fill gaps.

Why NSF Certified for Sport® Supplements Matter

When a supplement is NSF Certified for Sport®, it has been independently tested to make sure it’s pure, high-quality, and free from substances banned in sport. This protects athletes from the risks of contamination or unsafe ingredients — a major concern for those who compete.

That’s why MindFuel Athletics offers the Thorne Multi-Vitamin Elite — NSF Certified for Sport®. This means:

• It’s been thoroughly tested for banned substances
• Ingredients are transparent and listed clearly
• It’s trusted by professional and elite athletes worldwide

This gives you confidence that you’re fueling your body responsibly and safely.

⚠️ Reminder: Always take time to read through the ingredient label of any supplement to ensure it matches your needs, allergies, or sensitivities.

Tips to Maximize Your Vitamin & Mineral Intake

• Pair nutrients wisely: Vitamin C improves iron absorption; avoid taking iron with high-calcium foods at the same exact moment.
• Don’t megadose: More is not always better. Very high doses of some vitamins (like A, E) can be harmful.
• Spread intake: If your multivitamin or nutrients are mild, take with breakfast or lunch to let your body absorb them.
• Eat a rainbow: Different color fruits/veggies = different micronutrients.
• Stay consistent: It’s better to take a supplement every day than occasionally. Gaps add up.
• Hydrate and compete smart: Adequate water, rest, and good sleep all let the micronutrients do their job.
