The short answer
Fungal nail infections cause thick, discoloured, crumbly nails, usually toenails. They need antifungal treatment from a doctor; vitamins and home remedies do not clear them.
Taking a photo of your nails on day one gives you a fair comparison when the new growth reaches the tips a few months later.
Signs
Yellow or white discolouration, thickening and crumbling.
Nails are made of tightly packed layers of keratin produced in the nail matrix under the cuticle. Anything that affects the matrix shows up in the nail months later as it grows out.
Diagnosis
A clipping test confirms fungus, as many look-alikes exist.
Because fingernails grow about 3 mm a month, you can literally watch a routine work, or not, by looking at the new growth at the base over two to three months.

Prescription antifungals work best.
Dermatologists treat nails as part of the skin. New dark streaks, pain, swelling, nails lifting from the bed or thick discoloured toenails need a professional look.
Prevention
Keep feet dry and wear sandals in shared showers.
Moisturising nails is as important as moisturising hands. A drop of oil or cream massaged into the nail plate each night reduces peeling.
A quick checklist
- Massage cuticle oil in every night.
- File in one direction with a glass file.
- Take breaks between gel manicures.
- Photograph nails on day one.
- Check new dark streaks with a dermatologist.
White spots on nails are almost always minor knocks to the matrix, not a sign of calcium or zinc deficiency, despite the popular myth.
Putting it into practice
Most nail problems people notice, peeling, splitting and ridges, come from everyday wear: water, chemicals, tools used as nails, and age. Protective habits make the biggest difference.
Pick whichever tip above feels simplest and begin with it this week. Small early wins make the next habit easier, and routines grown gradually tend to survive far longer than big overnight overhauls.
Where Gelagen fits
A word about our own gummy: Gelagen works gradually over months, following the natural growth of skin, hair and nails, so it is a companion to good habits rather than a shortcut.

Common questions
Do white spots mean a deficiency?
Usually not; they are typically minor injuries.
Should I cut my cuticles?
No. Push them back gently and moisturise.
When should I see a doctor about nails?
For dark streaks, pain, swelling or thick discoloured nails.
Key takeaway
The short version: Fungal nail infections cause thick, discoloured, crumbly nails, usually toenails. Build the simple habits first, give any change two to three months, and see a dermatologist about anything that worries you.
Before you order, please read this. Gelagen is a dietary supplement, not a treatment for any skin, hair or nail condition. Each serving contains 5,000 mcg of biotin, which the FDA warns can interfere with some lab tests, including thyroid and troponin tests, so tell your doctor before any blood work. Ask first if you are pregnant or nursing, have a thyroid condition or take prescription medicine. Keep gummies out of reach of children, and see a dermatologist about sudden hair loss, new rashes or a changing mole.
