Vitamin trends are blowing up online, but taking vitamins the wrong way might do more harm than good.

From TikTok to Instagram, vitamin routines are everywhere. People are stacking multivitamins, collagen, vitamin D, zinc, B12, biotin, and even digestive enzymes hoping for glowing skin, better energy, and stronger immunity.

But what no one tells you is this: if you’re taking the wrong supplements or taking them without knowing what your body actually needs, you might be doing more harm than good.

  • Your skin breaks out or dulls despite all the skincare
  • You catch colds easily even though you work out
  • You feel drained, moody, or your hair is thinning
  • And the worst part is that your body might be aging from the inside out

Vitamins Aren’t The Problem. It’s How We Take Them.

We assume more vitamins mean better health. But if your body doesn’t need them or can’t absorb them properly, excess nutrients can:

  • Build up in your system
  • Disrupt natural hormonal and immune function
  • Trigger toxicity and imbalances you can’t see until it’s too late

Some overlooked risks:

  • Too much vitamin D: calcium overload, kidney damage, heart issues
  • Excess vitamin A: liver strain, headaches, hair loss, higher cancer risk
  • High doses of vitamin E: bleeding risk, poor clotting
  • Misused vitamin C: kidney stones, nausea, digestive upset

What Happens When You’re Taking Vitamins the Wrong Way

A real-life story: Nhi, 28, and her vitamin wake-up call

Nhi followed a clean-eating, gym-loving routine and took five different vitamins every day including D3, K2, zinc, collagen, and vitamin C. But over time, she felt off with low energy, poor sleep, and hair loss.

When tested, she found:

  • Severe magnesium and B6 deficiency
  • Excess calcium due to high vitamin D
  • A gene mutation impairing folate metabolism

Despite her discipline, she was unknowingly accelerating the aging process.

The Double-Edged Sword of Over- or Undersupplementing

Guessing your way through supplements can either leave your body starved or overloaded. Both extremes chip away at your long-term health.

  • Too much vitamin D: kidney stones, high blood pressure, artery calcification
  • Too little vitamin D: weak bones, poor immunity, chronic fatigue
  • Too much vitamin A: liver toxicity, fatigue, hair loss, higher cancer risk
  • Too little vitamin A: dry eyes, acne, weak immune system
  • Too much B6 or B12: nerve issues, tingling limbs
  • Too little B-complex: mood swings, poor sleep, low energy

Your Body Is Unique — Your Supplement Routine Should Be, Too

Taking vitamins without understanding your genetic blueprint is like wearing someone else’s prescription glasses. It just doesn’t fit.

Instead, start by asking:

  • Which nutrients am I truly deficient in?
  • Do I have genetic mutations that affect absorption?
  • Should I adjust my intake through food or supplements?
