The dietary supplement market is witnessing increasing interest with promises of improved health and energy, but it has become confusing for beginners between the benefits and the marketing hype.
Nutritionists and health professionals repeatedly warn against excessive consumption of supplements or their use without a genuine need, stressing that these products are not a substitute for a balanced diet and a healthy lifestyle.
Registered dietitian Ella Corman explains that the increased demand for supplements reflects a growing health awareness, but it has also led to a proliferation of products whose benefits and quality are difficult to verify. She says that many people are looking for extra support for their health, immunity, and energy, but the abundance of choices makes making the right decision complicated.
She adds that dietary supplements, as their name suggests, are intended to "complement" the diet and compensate for a possible deficiency in some nutrients, and are often available in the form of tablets, capsules, or powders.
One of the most common supplements is vitamin D, which helps support immunity and muscle and brain health, especially during the winter months when sun exposure is limited. Vitamin C is also used to support skin health and protect cells, while vitamin B12 is essential, particularly for vegetarians, for its role in red blood cell production and supporting the nervous system.
Fish oil, rich in omega-3 fatty acids, is used to support heart and brain health, while many people turn to magnesium for relaxation and improved sleep. Probiotics have also gained popularity for their potential role in supporting digestive health, as have multivitamins that combine several nutrients, such as calcium and zinc.
Despite these potential benefits, experts emphasize that the effectiveness of supplements depends on the body's actual need for them, noting that using them unnecessarily may be ineffective or even harmful in some cases. Therefore, it is always advisable to consult a healthcare professional before starting to take any supplement.
Ella Mann emphasizes that product quality is just as important as its type, explaining that the difference between one supplement and another can be significant in terms of ingredient concentration and effectiveness, even if the product looks similar. She also warns against being swayed by advertisements or trends, as these do not necessarily reflect true nutritional value.
She points out that supplements should be used to support a healthy lifestyle, not as a replacement for it. A balanced diet, good sleep, drinking water, and stress management remain the foundation for maintaining health.
Regarding common mistakes, nutritionist Carrie Ruxton points out that one of the most prominent is relying on influencer recommendations without considering individual needs. She explains that the body's needs vary according to age and health condition. For example, older adults need extra support with certain vitamins, while younger women need iron and folic acid, and children may benefit from essential vitamins such as A, C, and D
Vegetarians often need vitamin B12, iodine, zinc and vitamin D, making expert consultation an important step in choosing the right supplement.
Experts also warn against taking several supplements at the same time without awareness, as this may lead to an unsafe increase in certain elements such as vitamin A or iron, especially if they are found in more than one product.
Ella Mann explains that some supplements may interfere with absorption, such as calcium which may reduce iron absorption, or antimicrobial herbs which may affect the effectiveness of probiotics, so it is preferable to separate them at different times of the day.
Experts also point out that some elements are better absorbed under certain conditions. For example, fat-soluble vitamins are better absorbed with meals containing healthy fats, while iron is best taken with vitamin C to improve its absorption.
In conclusion, experts agree that dietary supplements can be beneficial when used consciously and as needed, but they do not replace the basics of daily health, and should not be treated as a quick fix or an alternative to a complete healthy lifestyle
