Dietary Supplements: Which Ones Are Worth Taking and What Should You Look For?

Which vitamins and minerals are important for the body?

A healthy body depends on a wide range of vitamins, minerals, and other essential nutrients.

• Vitamin D supports healthy bones and muscles, contributes to normal immune function, and helps maintain healthy vision.
• Vitamin C acts as an antioxidant, supports the immune system, and is important for healthy skin, blood vessels, and cellular protection.
• B vitamins, including B12, are essential for energy metabolism, nervous system function, muscle health, and overall performance.
• Magnesium is vital for normal muscle and nerve function, recovery, and energy production in the body.
• Zinc contributes to normal immune function, supports wound healing, and helps protect cells from oxidative damage.
• Vitamin E helps protect cells against oxidative stress, supports skin health, and contributes to normal immune function.
• Iron is essential for oxygen transport in the blood, energy production, and physical performance.
• Vitamin K contributes to normal blood clotting and plays an important role in maintaining healthy bones.
• Vitamin A is important for normal vision, healthy skin and mucous membranes, and normal cell function.
• Omega-3 fatty acids support cardiovascular health, brain function, and a normal inflammatory response. They are naturally found in fish, algae, and certain plant-based sources.
• Calcium is essential for strong bones and healthy teeth.

A varied diet rich in fiber, fruits, vegetables, fish, whole grains, and other nutrient-dense foods generally provides sufficient amounts of these nutrients. However, targeted supplementation may be beneficial in certain situations to help meet individual nutritional needs.

When dietary supplements are beneficial

Not everyone needs to take dietary supplements. However, there are certain life stages and groups of people who are at a higher risk of not getting enough essential vitamins and minerals.

When nutritional needs are increased

Pregnant women, breastfeeding mothers, and older adults are among the groups that may find it more difficult to meet their nutritional needs through diet alone.

During pregnancy and breastfeeding, the body's requirements for various vitamins and minerals increase significantly to support both mother and child. Older adults, on the other hand, often produce certain vitamins, such as vitamin D, less efficiently, making supplementation a sensible option in many cases.

For people with an active lifestyle

People who exercise regularly or are exposed to high levels of physical strain through their work often have increased nutritional needs to support normal muscle function and energy production. An inadequate intake may contribute to symptoms such as muscle cramps, increased fatigue, or reduced physical performance.

For specific dietary patterns

Vegetarians and vegans need to pay particular attention to getting enough vitamins and minerals that are found primarily in animal-based foods. These include vitamin B12, iron, and zinc. Targeted supplementation can help prevent deficiencies and support the normal health of the blood, muscles, and nervous system.

Vitamin or nutrient deficiencies

Certain nutrient deficiencies are common and can often lead to noticeable symptoms. One well-known example is vitamin D deficiency. Often referred to as the "sunshine vitamin," vitamin D is produced primarily through exposure to sunlight. During the winter months, insufficient sunlight can make low vitamin D levels more common, which is why many people choose to take vitamin D supplements.

Iron deficiency is also relatively common, particularly among women, and may cause symptoms such as fatigue, difficulty concentrating, or pale skin. Other possible signs of nutrient deficiencies include skin problems, hair loss, or a weakened immune system.

Which supplements are worth taking?

There is no one-size-fits-all answer to this question, as the need for dietary supplements depends largely on an individual's nutritional status, lifestyle, and personal health goals.

The first step is to determine whether the aim is to correct an existing deficiency, provide additional nutritional support, or promote long-term health through preventive supplementation. Depending on your goals, different supplements may offer different benefits for overall well-being.

For antioxidant support and cellular protection, products such as Spirosol for Humans or our anti-aging supplement NMN may be suitable options. The nutrient Nicotinamide Riboside may also help support cellular energy production when combined with a healthy lifestyle, while our Japanese Knotweed Drops are valued for their antioxidant properties and their potential to support healthy circulation.
