The supplement industry continues to thrive from multivitamins to individual nutrients even though the science behind their benefits remains limited.
For the average healthy adult, a well-balanced diet rich in fruits, vegetables, whole grains, and lean proteins are enough to meet the daily nutritional needs, according to an article on Harvard Health.
According to doctors, no supplements are required if an adult eats a variety of nutrient-dense food as it is the best way to ensure the human body gets the vitamins and minerals. Still, in certain situations, supplements may have a place.
When supplements are required?
Even though supplements are not necessary for everyone, some people may get benefits from targeted supplementation, particularly if they diagnosed deficiencies or specific medical conditions that interfere with nutrient absorption.
For example, strict vegans, who do not eat any animal-derived substances, may not get enough vitamin B12, which is found primarily in animal products. Low levels of vitamins B12 and B6 can stem from digestive disorders such as Crohn's disease, celiac disease, and ulcerative colitis, conditions that make it difficult to absorb nutrients.
Similarly, adults diagnosed with osteoporosis may require extra vitamin D and calcium beyond what they get from their regular diet. And for those who are lactose intolerant and avoid dairy products, supplements can help them to fill the gaps in vitamin D and calcium.
Differing opinions in medical community
The medical community has differing views about dietary supplements. Some doctors argue that supplements are not necessary while others suggest a "might-help-won't-hurt" approach as taking certain supplements to fill in nutritional gaps in one's diet may help without causing harm.
However, studies have shown that taking dietary supplements as prescribed are generally safe, and don't cause serious issues like side effects.
What you need to know before taking one?
If you are considering a supplement, first check with your doctor. A blood test may reveal whether you actually need dietary supplement, and your doctor can help you to choose what your health condition requires.
