What are vitamins and minerals?
Vitamins and minerals are essential nutrients that our bodies need to function properly. Vitamins are organic compounds that help regulate various bodily processes and support overall health. They are needed in small amounts and can be obtained from food or supplements. Minerals, on the other hand, are inorganic substances required for various physiological functions, such as building strong bones, transmitting nerve impulses, and maintaining fluid balance. They are also obtained through diet and are crucial for maintaining good health. Both vitamins and minerals play vital roles in keeping our bodies functioning optimally and preventing deficiencies and health problems.
Causes of vitamin and mineral deficiencies
Vitamin and mineral deficiencies can happen for a variety of reasons. One common cause is poor diet. If your diet is lacking in fruits, vegetables, or other nutrient-rich foods, you might miss out on important vitamins and minerals. Some health conditions, like IBS, can affect how your body absorbs nutrients. Some medications may interfere with nutrient absorption or increase nutrient excretion. Lifestyle choices, like restrictive diets or excessive alcohol consumption, can also lead to deficiencies. Some people, like pregnant women, young children, and older people, might need to pay extra attention to their diet to avoid falling short.
How to test your vitamin and mineral levels
Our vitamin deficiency test makes it easy to test your nutrient levels at home. It includes everything you need to collect a small blood sample and post it back to our labs. Our doctors will provide detailed insights into your vitamin and mineral levels and advice on how to improve your health. We recommend you collect your sample within 3 hours of waking up and before you eat.
FAQ
Do I need to take vitamin supplements?
A healthy and balanced diet should give you all the vitamins and nutrients you need, but supplements can help to boost deficiencies or to optimise levels where you are struggling to consume a diet rich enough in vitamins. Pregnant women need more ferritin, so supplementation might be a more convenient method to manage the body’s demands. We get a lot of our vitamin D from sunlight, so it can be helpful to take vitamin D supplements during the winter to boost levels of this important vitamin in the darker months or if you struggle to get enough sunlight to ensure your Vitamin D levels are optimised.
What foods are high in vitamins?
There are lots of vitamins and minerals your body needs to function properly, from energy to hair growth. The key to staying healthy is eating a balanced diet, limiting the amount of ultra-processed foods you consume and tracking your vitamins and minerals through blood testing to ensure you are managing any vitamin levels that could be improved.
What do vitamins help with?
Vitamins and minerals keep you going and ensure the normal functions of cells – from hair growth, energy, immune system, vision and so much more.
When do I take the test?
Collect your blood sample within 3 hours of waking and before food.
Does vitamin D help with mental health?
Vitamin D is considered a vital factor in mental health such as low mood, depression, and quality of life.
