Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. They are often referred to as "good" or "friendly" bacteria and are used to support gut health, immune function, and balance the microbiome. Common strains of probiotics include Lactobacillus, Bifidobacterium, and Saccharomyces boulardii.
People might take probiotic supplements to promote digestive health, manage symptoms of gastrointestinal disorders, support immune function, and improve overall well-being. Probiotics have been studied for their potential benefits in managing various health conditions, including irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and antibiotic-associated diarrhea. However, the efficacy of probiotics can vary depending on the strain, dosage, and individual factors.
While probiotic supplements can offer targeted support for gut health, it is also essential to consume a balanced diet rich in natural sources of probiotics, such as yogurt, kefir, sauerkraut, kimchi, and other fermented foods. These foods provide a diverse range of beneficial bacteria and also contain other health-promoting compounds. Consulting with a healthcare professional is advisable to determine the need for probiotic supplements and to identify appropriate strains and dosages based on individual health needs and conditions.
Vitamin C, also known as ascorbic acid, is an essential nutrient for humans and many animals. It is a water-soluble vitamin that is vital for the synthesis of collagen, a protein that is necessary for the construction of blood vessels, cartilage, muscle, and collagen in bones. Vitamin C is also a potent antioxidant, which means it helps protect cells from the damage caused by free radicals—molecules produced when your body breaks down food or when you’re exposed to tobacco smoke and radiation from the sun, X-rays or other sources. Unlike most animals, humans cannot synthesize vitamin C endogenously, which means it must be received through diet or supplementation.
Vitamin C is found in various foods, including fruits and vegetables, particularly citrus fruits like oranges and lemons, strawberries, bell peppers, spinach, kale, and broccoli. The body cannot store vitamin C, so it must be consumed regularly to maintain adequate levels. While it can be synthesized in a laboratory for supplements, natural sources of vitamin C are the preferred means of obtaining this vital nutrient because they provide additional beneficial compounds such as flavonoids that enhance its antioxidant activity.
The health benefits of vitamin C are numerous. It plays a critical role in the immune system by supporting various cellular functions of both the innate and adaptive immune system. Vitamin C enhances the skin’s defense system and accelerates the wound healing process. It also aids in the absorption of iron from plant-based foods and helps the immune system work properly to protect the body from disease. Furthermore, the antioxidant properties of vitamin C help fight against oxidative stress, which is linked to many chronic diseases.

A deficiency in vitamin C can lead to scurvy, a disease characterized by anemia, bleeding gums, bruising, and poor wound healing. On the other hand, adequate vitamin C intake through diet or supplements can help prevent or treat certain conditions. It is commonly used to reduce the symptoms of the common cold. Research also suggests that vitamin C may reduce the risk of chronic diseases such as heart disease, stroke, and certain types of cancer. However, it’s important to note that while vitamin C supplementation can support health, it is not a cure-all and should be part of a balanced diet and healthy lifestyle.

Zinc is a trace element that is essential for human health. It is involved in numerous aspects of cellular metabolism and is required for the catalytic activity of approximately 100 enzymes. It plays a vital role in immune function, protein synthesis, wound healing, DNA synthesis, and cell division. Zinc is also necessary for proper sense of taste and smell. A daily intake of zinc is required to maintain a steady state because the body has no specialized zinc storage system.
Zinc is not naturally produced by the human body and therefore must be obtained through diet or supplements. It is found in a wide variety of foods, including beef, poultry, seafood (especially oysters), beans, nuts, whole grains, and dairy products. The bioavailability of zinc from grains and plant foods is lower than from animal foods, though, because of the presence of certain compounds that bind zinc and inhibit its absorption.
The benefits of zinc for the human body are extensive. It is crucial for the normal development and function of cells mediating innate immunity, neutrophils, and natural killer cells. Zinc also has a role in modulating oxidative stress, inflammation, and immune response. It has been shown to reduce the duration and severity of cold symptoms, and its antioxidant properties can help fight off the damage caused by free radicals.
Zinc has been associated with the prevention and treatment of several diseases. Adequate zinc intake is essential in preventing zinc deficiency, which can lead to a variety of health issues, including impaired immune function, hair loss, diarrhea, and delayed wound healing. Studies have suggested that zinc supplementation can help reduce the incidence of pneumonia and diarrhea in children, improve outcomes for depression, and may even have protective effects against certain types of cancer, such as colorectal and esophageal cancer. However, it is important to note that excessive zinc intake can lead to toxicity and adverse health effects.
