What are Dietary Supplements and Their Uses?
Food supplements are products designed to provide you with key nutrients that your diet may miss. These include vitamins, minerals, amino acids, and compounds essential for cellular health or biological functions. They aim to fill the nutritional gap in your diet. Hence, they are also called nutritional supplements.
Dietary food supplements can support daily health and wellness by complementing your diet. Here’s why:
- Your regular diet may not be balanced; it may not be supplying all the nutrients you need.
- Your body may not be able to synthesise some compounds from diet alone due to ageing.
The Science Behind Dietary Supplements: How They Work
Supplements provide nutrients that your food might miss. But they aren't a substitute for a healthy diet. Instead, they offer an added support to help your body function well. For example, vitamin D helps your bones by making calcium easier to absorb.
Here are some facts behind the working of supplements:
- Bioavailability and Absorption: How well your body uses a supplement depends on its bioavailability. The type, content and formulation of the supplement can affect this. For example, liposomal supplements wrap nutrients in tiny fat bubbles. This protects them in the stomach so the body can absorb them better. Some combinations are also crucial. For instance, taking vitamin C with iron can help your body use iron better.
- Research & Evidence: Most supplements are backed by science and research. Their benefits are widely known and experienced. For example, omega-3 fatty acids are good for the heart as they help lower bad fats and blood pressure. Probiotics keep your gut healthy, which is key to overall health and immunity.
Knowing how dietary supplements work helps you choose wisely. Pick ones with solid science and high bioavailability for the best benefits. Now, how do these supplements work? The best dietary supplements promote your overall health and wellness in the following ways:
- Filling nutrient gaps: A busy lifestyle or an unbalanced diet may keep you from getting all the nutrients you need. Supplements fill these gaps! They provide essential nutrients, like vitamins, minerals, and other compounds your body needs every day.
- Support specific goals: Some supplements are designed for specific healthcare needs. For example, to improve energy levels and reduce fatigue, enhance liver health or support the immune system. Probiotics support gut health while antioxidants protect cells.
- Helping manage health conditions: Some supplements may aid in recovery and medical treatment. Some are known to enhance the body’s defence against diseases. These supplements are often taken under strict medical supervision.
Types of Dietary Supplements
Nutritional supplements are diverse in their types and forms. They meet different needs, preferences and tastes. Whether you need an energy boost, stronger immunity or healthy skin, there’s a supplement for you! Before considering what dietary supplements are good for you, it helps to know their varieties.
The common food supplement types include vitamins, minerals, herbs, probiotics, antioxidants, and digestive aids. Each has its own benefits. Let’s take a look at them one by one:
- Vitamins: They can feature one or more of the 13 essential vitamins. Some are fat-soluble vitamins (A, D, E and K). Whereas others are water-soluble (C and the 8 B vitamins).
- Minerals: Elemental nutrients that you may get from food in small quantities. They play a key role in biological functions, support healthy cells, bones and muscles. These include supplements of iron, magnesium, calcium and zinc or mineral complexes.
- Herbs and Botanicals: Herbal dietary supplements come from plants and are centuries old. They offer a natural way to support health. Berberine, ashwagandha, ginger, shilajit, mushrooms and curcumin are to name a few.
- Amino Acids: The basic building blocks of proteins. They play a key role in functions like tissue repair, muscle building, and hormone production. Glycine, ergothioneine, histidine, threonine, valine, and hydroxyproline, to name a few.
- Live Microbials: Also known as “probiotics”. They work as digestive aids and keep your gut microbiome healthy. For example, apple cider vinegar (with the mother). Many people use probiotics along with the best dietary fiber supplement to support digestion and gut health.
- Antioxidants: Some compounds in the body protect your cells from damage. Oxidative stress can damage cells and tissues, leading to early signs of ageing. Antioxidants help reduce this damage and protect cells. CoQ10, fisetin, NAD, resveratrol, to name a few.
Bonus Note: Cellular oxidative stress is a condition in which reactive molecules called free radicals are unbalanced. They attack healthy cells and tissues, causing damage. Eventually, it leads to a decline in cell health, poor organ function and various health problems.
