Vitamin supplements offer many different options, and may be essential for people following restrictive diets, suffering from nutritional deficiencies, being pregnant/breastfeeding mothers, and/or having health conditions like Crohn’s disease or celiac disease.
Supplements should always be used to complement a healthy diet, and before taking any, consult a physician or registered dietitian to ensure they’re appropriate.
Vitamins
Vitamins are nutrients the body requires in small amounts for proper function and health, found both in food and dietary supplements. Four fat-soluble vitamins (A, D, E and K) can be stored in liver fatty tissue; while water-soluble ones (Vitamin C and the B vitamins) cannot be stored as any excess is excreted through urine.
Use of multivitamin-multimineral dietary supplements is widespread among US adults. We used diet and supplement information from the Hawaii-Los Angeles Multiethnic Cohort to investigate nutrient adequacy between vitamin users and nonusers; our findings indicate that supplement use significantly decreased overall inadequate total intakes (diet plus supplements) except niacin.
When taking a multivitamin, one should avoid products with added herbs, enzymes or amino acids as these could interfere with how their bodies absorb vitamins and minerals. Furthermore, multivitamin supplements cannot replace eating healthily as foods contain phytochemicals which work together to lower disease risks.
Minerals
Minerals are natural solid substances characterized by an ordered internal arrangement of atoms and ions, manifested externally through crystal structures. Their study is known as mineralogy.
Supplement users had significantly higher mineral intake compared with non-users in one large study; however, this didn’t push their daily dietary intake over RDA levels significantly; perhaps as vitamins and minerals found naturally within foods work together while supplements tend to act on individual nutrients in isolation.
The Institute of Mining and Metallurgy (IMA) defines minerals as chemical compounds with well-established crystal structures and essential compositions, although the definition does not exclude organic compounds (like mellite), biogenic substances ( such as calcite), or amorphous solids such as glass. Furthermore, the IMA recognizes some natural substances without crystal structure that are more accurately called mineraloids; many names for minerals refer either directly or indirectly to who discovered or discovered it first.
Omega-3 Fatty Acids
Omega-3 fatty acids are polyunsaturated fats that serve many essential functions in our bodies, yet humans cannot make their own omega-3s. Therefore, food or supplement sources must provide them for us. The Institute of Medicine has issued recommendations regarding alpha-linolenic acid, or ALA; docosahexaenoic acid, or DHA; and eicosapentaenoic acid (EPA). ALA can be found in plant oils such as flaxseed (linseed), soybean, canola or chia seeds while it can also be converted by our bodies into DHA and EPA.

DHA and EPA are essential components of retinal cell membranes and brain tissues, according to various RCTs and case-control studies. A number of RCTs and case-control studies suggest that higher intakes of these nutrients could lower risk for age-related macular degeneration (AMD), leading to moderate to severe vision loss. However, results of the AREDS2 clinical trial show no reduction in progression to advanced AMD or wet AMD among older adults taking supplemented DHA and EPA supplements.
Nutraceuticals
Nutraceuticals are foods and supplements with health-promoting properties and may help lower risk for diseases, particularly cancer. Nutraceuticals may come from food or synthetic sources and range from herbal remedies to isolated nutrients.
Nutraceuticals differ from pharmaceuticals in that they do not require FDA regulation to purchase them and aren’t subject to clinically verified research, unlike pharmaceuticals which must meet specific limitations outlined by the Food and Drug Administration (FDA). Instead, purchasing them does not need a valid doctor’s prescription – although it is highly advised that people discuss with a healthcare provider the specific supplements they take and any possible side effects they might experience before making a decision on purchasing nutraceuticals.
Nutraceuticals combine nutrition and pharmaceutical medicine, but should never serve as a replacement for healthy eating habits. Whole food sources provide plenty of essential vitamins and minerals; however, when special diet restrictions or intensive physical activity prevent this, nutraceuticals may fill any nutritional gaps left by food alone – acting like preventive medicine by decreasing disease risks while postponing aging processes and increasing life expectancies.
