Let’s clear the air about food supplements. You have probably heard about vitamins, minerals and food supplements. You have also probably heard several debates on whether we really need food supplementation or not.

In this article, we hope to clarify why we believe that every one of us needs some sort of food supplementation to maintain a healthy life.

What are food supplements?

The dictionary definition of the term nutrition refers to “The process of taking in food and using it for growth, metabolism, and repair”[1]. Thus, the substances we take in as food, determine the nourishment of our bodies. The human body needs to acquire six categories of nutrients from food. These nutrients are proteins, carbohydrates, fats, fibres, vitamins and minerals. Due to our varied lifestyles and eating habits however, most of the global population is always lacking in at least one essential nutrient. Our diets therefore, require supplementation of these missing elements.

Nutritional supplementation refers to the addition of missing nutritional elements to our diet. Supplementation occurs either in the form of food sources or in the form of the pure nutrient packaged in tablets, capsules, gels or syrups of a fixed dosage. Food supplements, in particular, refer to the concentrated form of nutrients consumed in a dose form[2]. In addition to the food supplements of vitamins, minerals, amino acids and fatty acids that are currently available, plant-derived bioactive compounds are also available as food supplements. As they are not medicinal products, they are not intended to prevent or treat human diseases. Their goal is only to maintain the normal functioning of the human body.

In Europe, supplement use is common in Denmark and Germany (59% and 43% of the adult population respectively) but is not so common in Spain (9%)[3]. It is also estimated that more women consume supplements than men.

Types of food supplements

Vitamin Supplements

Vitamins are organic molecules required in adequate doses for the maintenance and proper functioning of our bodies. Whilst our body can produce many vitamins, there are many others that are only obtainable from a dietary source. However, due to easy excretion through urine or difficulties in absorption, our body’s stores of vitamins need to be constantly replenished. Further, some vitamins like vitamin D3, require adequate sunlight for its production[4]. Sun exposure is lower in the northern latitudes, particularly in winter. This leads to vitamin deficiencies, requiring supplementation from external sources, such as food supplements.

Supplementation of Minerals

Being inorganic elements, our bodies cannot synthesize mineral nutrients. All the minerals in our body come from plant or animal sources and drinking water. They are essential however, for many biochemical pathways. These include those involved in the body’s normal energy-yielding metabolism and immune function. Due to a lack of adequate access to a balanced diet however, a majority of the population is always lacking in one or more of the major minerals. For example, the World Health Organization estimates that 24.8% of the world population may have low serum iron levels[5] while 56.9% of the European population has an insufficient iodine intake[6]. It is imperative therefore, that we fortify our diet with mineral food supplements. This supplementation will help us to overcome mineral deficiencies.

Amino acid Supplements

Proteins are the building blocks of our body. A peptide is the non-functional subunit of a protein which is in turn composed of amino acids. Although the human body can only utilize 21 amino acids, they form the 25,000 known proteins encoded by the human genome. Of these 21 amino acids, the human body can not synthesise 9 of them. The body is also impaired in 6 others under certain pathophysiological conditions. Thus, most of the amino acids essential to meet the energy and metabolic demands of the human body need to be met through food supplementation.

Micronutrient deficiencies such as a vitamin B or zinc deficiency, an increase in physical activity or a lifestyle change such as smoking or alcohol consumption can also increase the metabolic demand[7]. Further, there is no conclusive evidence of long-term protein storage by the body. Regular food supplementation of amino acids thus seems to be the only way to maintain a healthy life-cycle.

Supplementation with plant extracts

Also known as phytoextracts, extracts from the various parts of plants are known to be important in traditional medicine. Plant extracts such as curcumin, quercetin and resveratrol have often been promoted to strengthen and regulate the immune system. They help fight upper respiratory infections, and act as potent anti-oxidant and anti-inflammatory compounds. Phytoextracts however, suffer from problems of very low bioavailability since they are generally poorly soluble in water and are rapidly metabolized[8],[9]. This highlights the need to continuously replace their body-supportive benefits through food supplementation.

Who needs food supplements?

As mentioned earlier, our bodies cannot synthesize a lot of the essential nutrients we need. Although these nutrients help with the normal functioning of our bodies, we have lost many of the synthesizing functions during evolution. Alternatively, some of these essential nutrients are simply not available to us. This can be due to a number of reasons, such as aging, disease and improper and imbalanced diets. A loss of nutrients from the body can also occur due to a high metabolic rate associated with sports and other heavy physical activity[10]. Finally, imbalances can also occur when we follow special diet regimens since they exclude certain food categories. Thus, some sources of essential nutrients no longer feature in our daily dietary intake.

Examples of population groups requiring specific advice about supplements[3]

The Global Food Supplement Market

The vitamin supplement market emerged as the largest segment of the global food supplement market in 2019 (revenue of USD 39.61 billion). Based on the market trends, the global food supplement market is likely to reach USD 230.73 billion by 2027, registering a CAGR (Compound Annual Growth Rate) of 8.2% from 2020 to 2027[11]. Of this, the proteins and amino acids segment is set to rise at a CAGR of 12.8% from 2020–2027. The global plant extract market, which is growing at a CAGR of 6%, has a projection of reaching USD 61.30 billion by 2025[12].

Summary of why we need food supplements

· The availability of essential nutrients like vitamins, minerals, amino acids and plant-derived bioactive compounds varies with age, sex, disease-state, diet and physical activity.

· Food supplements refer to the concentrated form of nutrients consumed in a fixed-dose powder, tablet, capsule or syrup form.

· Food supplements can correct nutrient imbalances and support the body’s normal functions.
