Cancer
Published in Gia Merlo, Kathy Berra, Lifestyle Nursing, 2023
Dietary supplements can play a valuable role in promoting health when limited consumption or absorption of a dietary nutrient or compound can’t provide amounts that are optimal for a specific individual. AICR/WCRF and ACS recommendations both advise, however, that the overall body of evidence does not support the use of dietary supplements as an effective strategy to reduce cancer risk (Rock et al., 2020; World Cancer Research Fund/American Institute for Cancer Research, 2018).
Chemosensation to Enhance Nutritional Intake in Cancer Patients
Published in Alan R. Hirsch, Nutrition and Sensation, 2023
Healthcare providers must exercise caution when recommending the use of any dietary supplements, as supplements are not regulated by the Food and Drug Administration, and could interact with other medications. Patients should be encouraged to disclose their supplement use to their provider to ensure the patient’s safety.

Published in Nicola Neale, Joanne Sale, Developing Practical Nursing Skills, 2022
Dietary supplements may need to be prescribed by a doctor. For some people, there may be an underlying medical problem affecting their nutrition, which needs to be treated. In some instances, weight gain, as experienced by Phillip, can be caused by an underlying medical condition, for example, an underactive thyroid gland (hypothyroidism).

Transparent public standards help promote manufacturers’ interests in global trade when pharmacopeial monographs are incorporated by reference into purchase contracts, etc. Scientifically valid public standards could also save the regulator and manufacturer resources since the analytical methods do not need to be revalidated. Traceability and documentary evidence of meeting pharmacopeial quality standards support the quality of dietary supplements throughout the supply chain. Suppliers are expected to provide their customers a certificate of analysis of the overall quality of a botanical ingredient that reflects the identity, strength, and limit of contaminants. Requiring suppliers to provide materials that conform to the monograph involves more testing that helps ensure that every batch meets uniform requirements for composition, identity, quality, purity, and strength (8). Blockchain systems using decentralized storage of blocks of botanical identity and quality data linked along the supply chain, secured using cryptography, may help in sustainable sourcing, quality assurance, and tackling adulteration/fraudulent substitution problems, particularly in cases of complex multiherbal preparations (15, 16).

As for the safety of dietary supplements, as mentioned by Alhomoud et al. (57), the results of this study indicate that most respondents (70.8%) do not believe in the absolute safety of this type of product. This result is corroborated by a large number of instructors (86.4%) who say they warn their customers about the possible risks associated with consumption. Explaining possible risks is fundamental, since the lack of effective regulations and the increasingly easy purchase of these products on the Internet contribute to weaker safety controls on dietary supplements, exposing the consumer to possible side-effects (35, 44, 62). It is important to highlight that although in this research most respondents warn about the possible risks of using dietary supplements, Druker and Gesser-Edelsburg (15) arrived at different results, finding that even knowing about the possible harmful effects of dietary supplements, instructors did not communicate this to customers, believing that the benefit outweighed the risk and even indicating that if taken in the correct doses, dietary supplements would not be dangerous.

Dietary supplements are intended to supplement the diet with ingredients such as vitamins, minerals, amino acids, and herbs or botanicals (FDA 2018). However, factors such as a lack of proper Good Manufacturing Practices (GMPs), ingredient substitution or removal, and unscrupulous ingredient sourcing can lead to supplement adulteration (Brown 2017). Under the Food Drug and Cosmetic (FD&C) Act, dietary supplements are a category of food with labeling regulations and registry reporting system separate from food and drugs (FDA 2018). Intentional adulteration in dietary supplements typically involves acts such as the use of ingredients that are not listed on the label to enhance claimed biologic or metabolic effectiveness; substitution of declared ingredients with cheaper alternatives; and/or use of unapproved non-dietary ingredients (NDIs) (Brown 2017). Previous market surveys on the contents of dietary supplements have reported mislabeling rates of 25% for shark cartilage pills (Hellberg et al. 2019), 42% for probiotic supplements (Morovic et al. 2016), and 58% for botanicals (Newmaster et al. 2013). These studies have reported instances of species substitution, such as alfalfa (Medicago sativa) substituted for elderberry (Sambucus nigra) (Newmaster et al. 2013) and winter skate (Leucoraja ocellata) substituted for shark species (Hellberg et al. 2019), as well as probiotics that don’t meet label claim or detection thresholds for strains listed on the label (Morovic et al. 2016).
