Globally, vitamin supplements are big business. In the United States alone, more than half of all Americans consume a vitamin supplement daily, with multivitamins being the most popular. It’s easy to see why they’re appealing, as many of the supplement brands offer promises such as pain relief, better gut health and improved general health, among others. However, as Dr Wael Berro knows, it is vital to speak with a doctor before trying a new supplement.
Understanding Vitamins
Collectively, vitamins and minerals are the micronutrients that nourish the body with what it needs to stay healthy. Micronutrients are found in food, and eating food types rich in vitamins ensures the body has what it requires to function optimally. Getting vitamins and minerals from foods is also the recommended path, as the body finds it easier to absorb them through food compared to a supplement.
While a balanced and varied diet typically provides the body with the nutrients it requires, deficiencies can happen. Whether it’s because of a disease that affects nutrient absorption or consuming an unbalanced diet, an individual can have vitamin deficiencies. Other causes such as taking certain medications, consuming excessive alcohol and pregnancy can also have an impact on vitamin and mineral levels in the body. As such, it is important to get these levels checked regularly.
As there are a variety of vitamins and minerals, symptoms of deficiencies can vary according to the micronutrient. Some of the most common deficiencies include:
- Iron: Iron is vital for the creation of red blood cells, so a deficiency in it can show up as body weakness, dizziness, shortness of breath, headaches and heart palpitations.
- Vitamin D: Inadequate Vitamin D in the body can show up as tiredness, weak bones, muscle pain, anxiety or depression, and vulnerability to sickness. Vitamin D is essential for the immune system and also supports bone and muscle health.
- Vitamin B12: This particular vitamin aids the proper functioning of the nervous system and is necessary for red blood cell production. Insufficient levels of B12 can lead to mouth ulcers, a swollen and sore tongue, blurry vision, extreme tiredness, body weakness, and a ‘pins and needles’ sensation.
A primary care physician can perform blood tests to check the levels of certain vitamins, according to the symptoms displayed. Should they determine that food alone cannot provide all the nutrients required, they can help decide if a vitamin supplement is needed.
