A consensus or society position rather than new primary data.
This is a narrative review that surveys the landscape of dietary supplement types (vitamins, minerals, herbals, probiotics, fatty acids, proteins) and summarizes reported associations with health outcomes across multiple organ systems and chronic diseases. The review emphasizes that supplements may complement—but cannot replace—balanced nutrition and medical therapy, and calls for stronger regulatory oversight, evidence-based education, and clinical research to establish efficacy and safety.
Narrative literature review. Narrative review of peer-reviewed literature, healthcare publications, and credible nutritional sources; focused on dietary supplement types and their use in health and disease management.
Dietary supplements reported to enhance nutritional status, immune health, metabolic state, oxidative stress markers, and cardiovascular, skeletal, gastrointestinal, and neurological health when used properly Review focuses on supplement roles in management of cardiovascular diseases, diabetes, obesity, immune-related disorders, and bone health conditions Concerns identified include improper intake, overdose risk, product quality variability, antagonistic interactions, and absence of clinical data for some products
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
Clinicians should view this review as a call to integrate evidence-based supplement counselling into practice while remaining cautious about product variability, drug–nutrient interactions, and gaps in clinical data. Supplements should be positioned as complements to, not replacements for, conventional treatment and balanced diet.
A narrative review synthesizing literature on dietary supplement types, purported health benefits, and disease management roles; provides expert synthesis but lacks primary data, effect sizes, or definitive comparative evidence.

With the growing awareness of preventative health care, nutritional adequacy and disease prevention, dietary supplements have come to play an ever-growing role in the contemporary healthcare and nutrition practice. They include vitamin based, mineral based, herbal preparations, probiotics, fatty acid-containing, protein supplements and other types of bioactive compounds that are commonly used to benefit physiological processes and health outcomes on the whole. The increasing global market of dietary supplements reflects the novel trends of consumerism, rise in the prevalence of chronic disease, ageing as well as an increase in the interest towards the personalisation of nutrition and wellness framework. This is what the review article aims at achieving, under the critical review of the major classes of dietary supplements, evaluation of reported health-benefits and dissection of how they can be used in conjunction with managing a disease, with new scientific knowledge. The review is based on the literature review design of narrative review and generalisation in the findings which is based on the peer-reviewed scholarly research, publications on healthcare and other credible sources of nutritional information. The available information demonstrates that dietary supplements can enhance the state of nutritional status, the health of the immune system, the metabolic state, oxidative stress, cardiovascular, skeletal, gastrointestinal, and neurological health problems when used properly. The role of dietary supplements in management of the major health conditions is given special attention which include cardiovascular diseases, diabetes, obesity, immune-related disorders and bone health conditions. Biological processes that are a part of supply action are also discussed in the review, and it has proved to interact nutrient intake and metabolic activities on clinical outcomes. Though the supplements may be used as a therapeutic supplement and complement to their conventional treatment therapies, there are some concerns on improper intake of supplements, overdose, product quality and an antagonistic interaction and absence of clinical data of some products. The results show that diet supplements in lieu of balanced nutritional foods and medical therapy are not possible but can be used as an aid to therapy under scientific evidence and medical guidelines. This review concludes that more regulatory checks, evidenced-based consumer education and ongoing clinical research are required to ensure that maximum benefits and minimum risks are achieved with the use of dietary supplement.
