Vitamins & minerals

Vitamins and minerals are essential nutrients that play key roles in almost all bodily functions. They are required in small amounts but have a major impact on our health. Unlike macronutrients such as carbohydrates, proteins, and fats, which provide energy, vitamins and minerals do not provide energy themselves. However, they help the body utilize the energy produced by macronutrients. Here are some of their main functions:

1. Immune system supportVitamins such as vitamin C, vitamin D, and certain minerals like zinc and selenium strengthen the immune system, helping the body fight infections and illnesses.

1. Vitamin A.Role: Essential for vision, the immune system, and reproduction. It also helps the heart, lungs, kidneys, and other organs function properly.Sources: Carrots, spinach, fortified milk, apricots.
2. B Vitamins (B1, B2, B3, B5, B6, B7, B9, B12).Role: Crucial for converting food into energy, forming red blood cells, and maintaining a healthy nervous system.Sources: Meat, fish, eggs, leafy green vegetables, milk, whole grains.
3. Vitamin C.Role: Important for growth and tissue repair throughout the body, wound healing, and maintaining healthy cartilage, bones, and teeth. Supplementation during winter can help prevent frequent colds.Sources: Citrus fruits, strawberries, peppers, broccoli, kiwis.
4. Vitamin D.Role: Essential for bone health as it helps the body use calcium from food. With less sunlight, a small supplement can also support proper body function.Sources: Sun exposure, fatty fish, egg yolks, fortified milk.
5. Vitamin E.Role: Acts as an antioxidant, helping to protect cells from damage caused by free radicals.Sources: Vegetable oils, nuts, seeds, spinach, broccoli.
6. Vitamin K.Role: Necessary for blood clotting and bone health.Sources: Leafy green vegetables, soybean oil, fish, meat, cheese.

These vitamins are essential because the body cannot produce them in sufficient quantities, so they must be obtained from the diet. A balanced and varied diet usually meets most people’s vitamin needs. However, in certain cases, such as for individuals with specific nutritional requirements or limited sun exposure (for vitamin D), supplements may be necessary.

Minerals play a crucial role in overall health, participating in numerous bodily functions, from building bones and teeth to regulating metabolism. Here is an overview of essential minerals and their importance:

Calcium

Role: Iodine is crucial for the production of thyroid hormones, which regulate metabolism, growth, and the function of key organs.

Sources: Iodized salt, dairy products, seafood, and seaweed.

Selenium

Role: Selenium protects cells and tissues from damage due to its role in antioxidant defense. It is also important for thyroid function regulation and the immune system.

Sources: Brazil nuts, fish, meats, eggs, and whole grains.

Minerals are indispensable for maintaining a healthy body and must be consumed in adequate amounts. A balanced and varied diet is generally sufficient to meet most people’s mineral needs. However, in some cases, supplements may be necessary to fill nutritional gaps, especially for athletes or vegans. It is also not always possible to provide the body with all the nutrients it needs without consuming excessive amounts of food, which can lead to a calorie surplus often incompatible with fitness goals. QNT offers a range of products that can help supplement essential mineral intake, supporting a healthy and active lifestyle.

The question of whether dietary supplements are necessary is complex and varies depending on the individual, their lifestyle, diet, and specific health needs. Dietary supplements are designed to complement the diet and provide nutrients—such as vitamins, minerals, fatty acids, or amino acids—that may be lacking or not consumed in sufficient quantities in daily food intake.

General Considerations

• Balanced diet: For most people, a balanced and varied diet should provide all the necessary nutrients for optimal health. This includes a wide variety of fruits, vegetables, lean proteins, whole grains, and healthy fats.
• Specific needs: However, certain populations or individuals with specific needs may benefit from dietary supplements. For example: Certain health conditions can reduce nutrient absorption or increase requirements, necessitating supplements.

Health Considerations

It is important to note that dietary supplements are not intended to replace a healthy diet or cure diseases. They should be used to complement the diet when nutrient needs are not met or in the case of confirmed deficiencies.

Advice Before Taking Supplements

• Medical consultation: Before starting any supplement regimen, it is advisable to consult a healthcare professional. This is especially important for individuals taking prescription medications, as some supplements can interact with medications.
• Quality and safety: Choose high-quality supplements approved by regulatory bodies or independent third parties to ensure safety and effectiveness.

While dietary supplements can be beneficial for some people, they are not necessary for everyone. An individualized approach, based on specific nutritional needs, lifestyle, and health conditions, is essential to determine whether supplements are appropriate. QNT, as an expert in dietary supplements, offers a range of products designed to support various health and wellness goals, allowing everyone to find the nutritional support suited to their unique needs.

Vitamin and mineral deficiencies can manifest through a variety of symptoms, depending on the missing nutrient:

General fatigue: May indicate a deficiency in iron (anemia), vitamin D, or B vitamins, particularly B12 and folate.

Skin and hair issues: Dry skin, bruising, and hair loss can signal deficiencies in vitamin A, vitamin C, zinc, or biotin.

Bone and joint problems: Bone pain and increased fragility may be related to a deficiency in vitamin D or calcium.
