A dietary supplement is usually a manufactured item intended to supplement one’s daily diet by taking a capsule, tablet, liquid or powder form. Such a supplement may give essential nutrients both extracted from food resources or which are synthetic so as to increase the daily amount of the consumed intake. Some dietary supplements are made from plant sources and are used for curing illnesses and promoting general health. Others are synthesized and are used for promoting weight loss and as energy boosters. Still others are both extracted from plants and synthesized but which are used for general well being.
Vitamins such as vitamin A, vitamin C and vitamin D are amongst the most popular supplements. The role of these vitamins is to maintain good health by keeping the body adequately nourished. Vitamin A, in particular, is extremely important for preventing heart disease and cataracts, as it stimulates the production of collagen, which helps repair damaged vessels and prevents clogged arteries. Deficiency of vitamin C results in weakening of the bones and increased vulnerability to infection.
There are many dietary supplements available on the market. It is recommended that before taking any of these, you consult your doctor who will advise you about the contents of the tablets. This is because some of the medicines are contraindicated for people who are under medication or undergoing any treatment for high blood pressure, heart disease, diabetes and cancer. Taking any of the medicines without proper consultation of doctor can result in adverse effects. Similarly, some medicines cannot be taken along with other medicines because of the differences in their chemical compositions.
The effectiveness of these dietary supplements depends not only on their ingredients but also on the correct dose and the right method of intake. A mix of a variety of nutrients in the form of tablets or capsules ensures that the nutrients get into the body thoroughly and stay there for the required time. These tablets must not be consumed immediately after eating and should be chewed properly before swallowing. If you think that you are not getting all the nutrients in your diet from your food, then you can take these supplements instead.
Most of these supplements are made up of vitamins, minerals and proteins. Vitamins constitute about 80% of the total nutrients in the diet. However, your body requires a balance of vitamins and minerals from the diet, so supplements may also be helpful. If your diet is rich in vitamins A, C and E, then chances are high that your skin stays healthy and glowing. However, if you are not getting any supply of these vitamins and minerals from your food, then you may need supplements to maintain a healthy skin.
Similarly, most of these dietary supplements contain essential fats, amino acids and a variety of herbs and spices. They work as antioxidants, which help prevent free radicals from damaging your body cells. Free radicals are caused by excessive alcohol, tobacco and air pollution. Antioxidants keep your skin looking young and fresh. However, healthcare providers advise that you should not use these medicines along with other medicines. These medicines may have side effects, if taken at the same time as other drugs or medicines prescribed by your doctor.
If you want to stay fit and healthy, you need to follow a strict diet and take dietary supplements to get enough nutrients. Your diet should contain more fruits, vegetables, whole grains, low-fat dairy products and lean meats. You should drink a lot of water and take supplements to ensure that you get enough hydration.
While purchasing dietary supplements, make sure that the ingredients mentioned in the label are genuine and safe. Some supplements contain harmful ingredients like caffeine, nicotine and alcohol, which can cause health problems. You will find a number of supplements containing ingredients like amino acids, ginseng, licorice root, green tea and beta carotene which improve the production of collagen, elastin and hyaluronic acid in your body. If you take these supplements, your skin will look healthy and firm.
