1. The "Glass" Nail Problem
We often assume that a "strong" nail is a hard nail. So, when our nails start snapping or peeling, we buy calcium hardeners. However, hardness without flexibility is brittleness. Think of a piece of glass: it is incredibly hard, but if you tap it, it shatters. Now think of a plastic ruler: it is strong because it can bend under pressure and snap back. If your nails are snapping, they don't necessarily need to be harder; they may need to be more resilient. Dryness, frequent wet-dry cycles, and low overall protein intake can all contribute to fragile, peeling nails.
The "Peeling Layers" Sign
When a nail peels in layers (onychoschizia), it is a sign that the structure holding the keratin layers together is under strain. This “bond” is influenced by hydration, oils (lipids), and protein building blocks. Topical polish can create a temporary seal, but supporting nails from the inside usually means improving hydration and ensuring you get enough quality protein. Adding a warm daily cup of Collanature Bone Broth Concentrate can be one simple way to increase your intake of collagen-rich protein as part of a nail-support routine.
2. Calcium vs. Collagen: The Balance
Nails are made primarily of keratin (a protein), but their strength and appearance can be influenced by overall nutrition.
- Minerals (like calcium, zinc, magnesium): help support normal structure in many tissues.
- Protein (keratin building blocks): supports the nail’s core structure. If you focus only on “hardness” without supporting protein and hydration, nails can still feel brittle.
A collagen-rich food like bone broth concentrate can fit well alongside a balanced diet that includes minerals, healthy fats, and plenty of fluids.
3. The Blood Flow Factor
The nail matrix (the root under the cuticle) is one of the fastest-growing tissues in the body. It needs consistent delivery of oxygen and nutrients. If you have poor circulation (cold hands), low iron, or a generally low-protein diet, nails can grow more slowly and feel weaker. Warm, easy-to-digest nutrition can be a practical “low-effort” support, especially when appetite or digestion is not at its best.
4. Recovering from Gels and Acrylics
The UK love affair with gel polish has a downside. The removal process (often involving acetone and buffing) can strip oils and dehydrate the nail plate, leaving it thin and prone to peeling. During a “polish holiday”, focus on gentle external care (oil, gloves for washing up) and consistent internal support: hydration, adequate protein, and a routine you can stick to. Some small studies on collagen peptides suggest potential improvements in nail brittleness and growth over time, but results vary and consistency matters.
5. Frequently Asked Questions
Do white spots mean I need calcium?
Not always. White spots (leukonychia) are often signs of minor trauma (banging your finger). If you suspect a deficiency, it is best to discuss it with a healthcare professional.
How long to fix peeling nails?
A fingernail takes roughly 4–6 months to grow from root to free edge. You may notice healthier growth near the cuticle first (within 4–8 weeks), but repairing the tips takes time as old damage grows out.
Why do I have vertical ridges?
Vertical ridges can be influenced by age, dryness, and repeated exposure to water/chemicals. Hydration, gentle care, and adequate protein intake can support healthier-looking growth.
Is biotin essential?
Biotin can help some people, but it works best as part of a broader foundation: protein, minerals, and hydration. Think of biotin as the “toolkit” and nutrition as the “materials”.
Does washing up damage nails?
Frequent wet-dry cycles can weaken nails because the nail plate expands in water and contracts as it dries. Gloves help. Supporting hydration and overall nutrition can also make nails feel less brittle over time.
Final Thoughts
Don’t settle for nails that act like glass. By balancing hydration, protein, and sensible external care, you support nails that are strong enough to work, but resilient enough to last.
