The Science of Nutrition: Why Vitamins and Minerals Matter

Your body is like a car — it needs fuel to run. Food gives us energy, but that’s not enough. To actually use that energy, repair cells, and keep the engine (our heart, brain, and immune system) working, we also need tiny helpers called vitamins and minerals.

Think of them as the spark plugs, wires, and fluids that make everything run smoothly. Without them, the car may start, but it won’t last long.

Why They Matter

• Vitamin C: Supports your immune system and helps heal cuts.

• Vitamin D: Works with calcium to build strong bones.

• B Vitamins: Help turn food into usable energy.

• Magnesium and Zinc: Important for sleep, mood, and healthy cells.

• Antioxidants (like Vitamin E, NAC, and ALA): Protect your body from “oxidative stress” — kind of like rust forming inside your cells.

What Happens If We Don’t Get Enough?

Even small shortages can make a big difference. You might feel tired, get sick more often, or notice trouble focusing. Long-term, low levels of key vitamins and minerals can raise risks for heart, brain, and immune problems.

Why Supplements Can Help

Most of us don’t eat a perfect diet every day. Fast food, stress, or certain habits (like smoking or cannabis use) can drain nutrients from the body. A daily multivitamin helps cover the gaps — giving your body what it needs to stay strong over time.
