Dietary supplements have become increasingly popular in recent years as individuals seek to optimize their health and well-being. When it comes to popular dietary supplement ingredients, several categories stand out, including vitamins, minerals, amino acids, enzymes, botanicals, and more. Each of these components plays a crucial role in supporting various physiological functions in the human body, and their supplementation can help to fill nutrient gaps and promote overall health. It is worth mentioning that the use of dietary supplements has increased significantly over the years, prompting scientific review and research into their efficacy and safety.
Some Popular Dietary Supplement Ingredients
Vitamins
Vitamins are organic compounds that are essential for various physiological functions. They serve as coenzymes in enzymatic reactions, regulate gene expression, and play important roles in immune function and antioxidant defense. A study by Hemilä and Chalker (2013) published in Cochrane Database of Systematic Reviews highlighted the potential benefits of vitamin C supplementation in reducing the duration of common cold episodes. This example demonstrates the popularity and scientific support for the inclusion of vitamin C in dietary supplements. [1]
Minerals
Minerals such as calcium, magnesium, and zinc are commonly included in dietary supplements due to their roles in maintaining bone health, muscle function, and overall metabolic processes. For example, in dietary supplements, zinc can be found in various forms such as elemental zinc, zinc gluconate, zinc sulfate, zinc picolinate, and zinc acetate. Cindy Crawford, et al. reviewed six studies on zinc supplementation. One of the studies in children provided data showing that the risk of developing the common cold was significantly reduced after taking preventive zinc for seven months. [2] A review in Bone by Rizzoli, R (2008) highlighted the importance of calcium and vitamin D supplementation for bone health in postmenopausal women, providing scientific evidence for the inclusion of these minerals in dietary supplements. [3]
Amino Acids
Amino acids are fundamental in protein synthesis, muscle repair, and overall physiological function. Examples of popular amino acid ingredients include L-glutamine and branched-chain amino acids (BCAAs). A work by Cruzat et al. (2018) in Nutrients reviewed the metabolism of glutamine in key organs such as the intestine, liver, and skeletal muscle and its importance to immune system cells. [4]
Enzymes
In dietary supplements, enzymes are commonly included to support digestion, absorption, and overall nutrient utilization. For example, proteases are enzymes that help break down proteins into smaller peptides and amino acids, facilitating their absorption in the intestines. Lipases aid in the digestion of fats, while amylases break down carbohydrates into simple sugars. Recently, Park HJ, et al. reviewed the application of digestive enzyme supplements in various fields, including prescription drugs, over-the-counter drugs, and enzyme foods. [5]
How to Choose Dietary Supplement Ingredients?
When selecting dietary supplement ingredients, it is crucial to consider several factors to ensure efficacy and safety. Firstly, scientific evidence from well-conducted clinical trials and research studies should support the use of the ingredients. Additionally, the quality, bioavailability, and dosage of the ingredients play a significant role in their effectiveness. The source of the ingredients, manufacturing processes, and regulatory standards should also be considered to ensure product quality and safety.
