Vitamins and Minerals

Why Does Your Body Need Vitamins and Minerals?

Vitamins and minerals are micronutrients – substances that the body cannot produce in sufficient quantities on its own, yet absolutely needs for hundreds of biochemical reactions.

They govern your energy metabolism, immune response, hormone production, and the proper functioning of your nervous system. Without them, your cells would simply stop functioning properly.

According to extensive research, more than 2 billion people worldwide suffer from a deficiency in at least one micronutrient – and the Czech Republic is no exception. The most commonly lacking nutrients are vitamin D, vitamin B12, magnesium, and zinc.

How can you tell if you're lacking vitamins or minerals? The most common signs include:

• Chronic fatigue and exhaustion even after adequate sleep
• Weakened immunity – frequent colds and infections
• Muscle cramps and tingling in the limbs
• Poor concentration and mood swings
• Brittle nails and hair, dry skin
• Slow wound healing and increased bruising

These symptoms are warning signs you shouldn't ignore. Vitamin and mineral supplements are specifically designed to reliably fill these gaps in your nutrition.

Water-Soluble and Fat-Soluble Vitamins

Vitamins fall into two categories – water-soluble vitamins and fat-soluble vitamins. The key difference lies in how they are absorbed and stored in the body. This distinction directly affects how and when you should take them.

Water-Soluble Vitamins (C, B Complex)

Water-soluble vitamins – namely vitamin C and the entire B vitamin group (B1, B2, B3, B5, B6, B7, B9, B12) – are not stored in the body. Whatever your body doesn't use is excreted in urine. On one hand, this means a lower risk of toxicity; on the other, they need to be replenished regularly – ideally every day.

What they do for you:

• Vitamin C: A powerful antioxidant that supports collagen synthesis, immunity, and iron absorption.
• B Complex: Essential for energy metabolism – converting carbohydrates, fats, and proteins into energy.
• Vitamin B12: Essential for the nervous system and red blood cell production; most commonly deficient in vegetarians and vegans.
• Folic Acid (B9): Critical during pregnancy for the development of the foetus's nervous system.

Fat-Soluble Vitamins (A, D, E, K)

Fat-soluble vitamins – vitamin A, vitamin D, vitamin E, and vitamin K2 – are stored in adipose tissue and the liver. On one hand, this means you don't need to supplement them daily (unless necessary); on the other, excessive intake can lead to toxicity.

Why they are essential:

• Vitamin D3: Regulates calcium absorption and is crucial for bones and immunity. More than 50% of Czechs have insufficient levels, particularly during winter.
• Vitamin K2: Ensures calcium is directed to the bones – and not the blood vessels; it works synergistically with vitamin D3.
• Vitamin A: Supports eye health, skin health, cell function, and immunity
• Vitamin E: Protects cell membranes from oxidative damage

It is essential to take fat-soluble vitamins with a meal containing fat – otherwise their absorption is dramatically reduced.

Minerals: The Silent Foundation of Your Performance and Health

Minerals (minerals) are also divided into two categories – macrominerals (needed in larger quantities) and microminerals, also known as trace elements (small doses are sufficient, but their absence makes itself felt quickly).

Macrominerals: Magnesium, Calcium, Potassium

Magnesium is one of the most essential minerals. It is involved in more than 300 enzymatic reactions in the body. Magnesium supplementation has been shown to significantly reduce cortisol levels (the stress hormone) and improve sleep quality (Boyle et al., 2017). If you're troubled by muscle cramps, insomnia, or chronic stress, magnesium should be your first port of call.

Calcium is the most abundant mineral in the body – nearly all of it is stored in the bones and teeth. It works in conjunction with vitamin D3 and K2, without which it cannot be properly absorbed and utilised.

Potassium regulates blood pressure and ensures the proper function of the cardiac muscle.

Trace Elements: Zinc, Selenium, Iron

• Zinc: Essential for immune function, wound healing, healthy skin, and male hormone regulation. Taking zinc within 24 hours of the first cold symptoms reduces its duration by 33% (Singh & Das, 2011).
• Selenium: A powerful antioxidant that supports thyroid function and protects DNA from damage.
• Iron: Essential for haemoglobin production and oxygen transport; deficiency causes iron-deficiency anaemia – with symptoms such as pronounced fatigue, shortness of breath, and pallor. Caution is advised – iron toxicity from excessive intake is a real risk; do not supplement iron without first checking your ferritin levels.

How to Choose the Right Vitamins and Minerals: A Practical Buyer's Guide

There are hundreds of products on the market – but the right choice depends on your goals, lifestyle, and any existing deficiencies. Here is a practical guide to help you choose:

Multivitamin or Individual Supplements?

A multivitamin is the ideal choice for those who want to cover all micronutrient intake simply and without complex planning.

In our online shop, you'll find dedicated categories for vitamins for men and vitamins for women. This doesn't mean that men and women need entirely different micronutrients. The difference lies in the dosage of key nutrients – for example, women generally require more iron and folic acid, while men need zinc and vitamin D3 in different ratios.

Individual supplements are the better choice if you have a lab-confirmed deficiency of a specific nutrient, or if you're targeting a particular concern – such as fatigue (B complex + magnesium), immunity (vitamin C + zinc + vitamin D3), or bone health (calcium + vitamin D3 + vitamin K2).

Vitamins for Athletes: Increased Micronutrient Demands

If you exercise regularly, your body requires vitamins for athletes in higher doses. Intense physical activity increases the demand for magnesium (lost through sweating), vitamin C (oxidative stress), B vitamins (energy metabolism), and zinc. Athletes following a vegetarian or vegan diet should also pay close attention to vitamin B12 and iron.

When and How to Take Vitamins

• Fat-soluble vitamins (A, D, E, K) – always take with a meal containing healthy fats (avocado, olive oil, nuts)
• Water-soluble vitamins (C, B complex) – can be taken at any time, ideally in the morning to support energy levels throughout the day
• Magnesium – in the evening, to support muscle relaxation and sleep quality
• Zinc – best taken with food to reduce the risk of nausea
• Calcium – in divided doses (max. 500 mg at a time) for better absorption

Watch out for combinations: Vitamin D3 and K2 are a synergistic pair – take them together. Conversely, iron and calcium compete for absorption – separate their intake by at least 2 hours.
