Symptoms of vitamin deficiency include brittle hair and nails, mouth ulcers, hair loss, scaly patches on the skin, and more. Recognizing these signs can help you adjust your diet accordingly. A well-balanced, nutritious diet has many benefits. Most people don't need to take vitamin supplements and can get all the vitamins and minerals they need if they eat a healthy, balanced diet.
The body needs different amounts of certain nutrients at different times in life. For example, the ability to absorb and process some nutrients decreases with age. Therefore, older adults may need more of certain vitamins and minerals, such as vitamin D, vitamin B12, and calcium. There are a few reasons why you might need to take a supplement.
Depending on your diet, you may need to take certain supplements to cover the nutrients you don't get from food. If you think your diet lacks certain vitamins or minerals, your doctor may recommend a blood test to confirm this. For example, if you've been vegan for a few years, you might want to check your levels of vitamin B12, calcium, and vitamin D. These levels range from bodily injuries that worsen with direct sunlight to gastrointestinal symptoms such as constipation, diarrhea, nausea, and vomiting.
