Your body might be trying to tell you something is wrong if you always feel tired and have brittle nails. In today’s fast-paced world, where people eat a lot of processed food, don’t eat well, and are under a lot of stress, vitamin deficiencies are becoming more common. But most of the time, they go unnoticed. These problems don’t always make a big deal about themselves like serious illnesses do. The body, on the other hand, sends out quiet warning signs that are easy to miss.”Vitamin deficiencies are much more common than people think, especially in cities,” says Dr Mohit Sharma, a Senior Consultant in Internal Medicine at Amrita Hospital in Faridabad. “The problem is that the symptoms are usually mild and not very specific, which makes it harder to diagnose and treat.”These five small signs could mean that you don’t have enough of something:
1. Do you always feel tired? It Could Be More Than Just Stress
If you feel tired all the time, even after getting enough sleep, you might not be getting enough Vitamin B12 or Vitamin D. These nutrients are very important for keeping nerves working and making energy. If you ignore this early sign, you might feel more tired and less able to get things done. 
These seemingly minor issues could be red flags for vitamin deficiencies that many of us ignore in our hectic routines.
2. Hair loss that doesn’t stop
In the winter, it’s normal for hair to fall out, but if it happens too much or for too long, it could be because you don’t get enough iron, biotin, or vitamin D. Hair follicles need a steady supply of nutrients, and if they don’t get enough, it can mess up their natural growth cycle.
3. Sores in the mouth or lips that are cracked often
People often don’t pay attention to ulcers or cracks that keep coming back at the corners of their mouths. But they could also mean that you don’t get enough B-complex vitamins, such as B2, B6, and B12. Putting medicine on the skin might help for a little while, but the real problem is usually deeper.
4. Tingly hands and feet
Don’t ignore a feeling of “pins and needles” that doesn’t go away. It could be a sign that your nerves are being hurt by not getting enough vitamin B12. It could lead to more serious neurological issues if you don’t treat it.
5. Skin that is pale and nails that break easily
If your skin is unusually pale or your nails are weak and brittle, you might not be getting enough iron, folate, or vitamin C. These nutrients are important for keeping blood flowing and fixing damaged tissue.Dr. Sharma says, “The good news is that most of the time, a simple blood test can tell you if you are lacking in vitamins.” You can avoid long-term health problems by changing your diet or taking supplements.As people change their habits, the risks to their health change as well. The first step toward getting better might be to pay attention to these small, quiet signs. 
Doctors warn that ongoing tiredness, mouth ulcers, and numbness in your limbs could hint at a deficiency in key vitamins like B12 or D.
