Supplements: One Biggest Mistake and Five Big Mistakes When Taking

Avoiding common pitfalls. How to ensure the safe and effective use of supplements.


In today’s world, people have become too comfortable and more spoilt by the benefits of civilisation. The producers not only of fast food but also supplements have also joined in. You do not have to cook anything, it’s easy and simple. Take a pill and forget. Everyone from friends to nutritionists is talking about magic supplements. But are they so beneficial and necessary for the human body?

Our body system is perfect and well thought out. We can take all vital nutrients from what nature has given us. Nature offers us all the great healthy foods we need, but they do not come in convenient bottles with unknown contents.

One biggest mistake – choosing supplements over food

Why is a balanced diet so much better than synthetic supplements? Whole foods such as fruit, vegetables, cereals, meat, fish and dairy products contain everything you are looking for in pills and more.


Nine big advantages of prioritising foods over supplements

1Real food is more nutritious

Whole foods contain a variety of nutrients that your body needs. Supplements can’t replace the many benefits of a healthy, diverse diet.

2Foods have fibre essential for digestion

Fibre is necessary for digestion. It also prevents the development of a number of diseases. Soluble fibre (found in pulses, some cereals, some fruit and vegetables) and insoluble fibre reduce the risk of different conditions such as cardiovascular diseases, diabetes and constipation.

3Contain phytochemicals and bioactive compounds

Many fruits, vegetables, whole grains, legumes and nuts contain special substances called phytochemicals (phytochemicals are naturally occurring compounds found in plant-based foods). They prevent the development of cancer, cardiovascular diseases, osteoporosis and diabetes.

But just think how much you lose by sticking to supplements. A balanced diet is a source of health and well-being. With a balanced diet, your body will have enough macro and micronutrients, you will be full of energy and will not have any deficiencies.

4You can’t substitute food’s taste


Food is a perfect and quick source of energy and a good mood. It gives us a variety of tastes and colours. We always have a choice of what to enjoy today for breakfast or lunch. You have to agree that you can’t do that with supplements. Something sealed in a capsule or a pill can often have a pungent smell and far from the most addictive taste, similar to medicine. So food is a much better and healthier choice than a pill you don’t know how it might affect you.

5Food is better absorbed by the body

The body tends to absorb nutrients from food more effectively than from supplements. This is because whole foods provide a complex mix of vitamins, minerals, and other nutrients that work together to promote optimal absorption and utilization.

Body mechanisms process and absorb the nutrients found in food, whereas the body may have a harder time breaking down and utilizing some of the nutrients in supplements, especially those that are synthetic or isolated forms of certain nutrients.

6Much better for your gut and microbiome

Whole foods contribute better to gut and microbiome health than supplements. The gut microbiome is a complex and diverse ecosystem of microorganisms that play an important role in maintaining overall health. Whole foods are high in nutrients, dietary fibre and other organic ingredients that can promote the growth of beneficial bacteria and support a healthy gut environment. In contrast, supplements often contain limited amounts of individual nutrients and do not have the same range of beneficial compounds found in whole foods.

7More difficult to overdose

Overdosing nutrients from food is usually much more difficult than from supplements. This is because the nutrients in whole foods are often accompanied by other components such as fibre and bioactive compounds that help regulate their absorption and use in the body. In addition, the number of nutrients in whole foods is often balanced and regulated by nature, this helps prevent overconsumption.

8Easier to control the quality

When you consume food, you have more control over its quality than a capsule-packed supplement. Food products must follow strict standards for safety, labelling and composition, and are subject to periodic checks and monitoring. Supplements, in contrast, are poorly regulated and the quality of these products can vary widely. They may contain contaminants, impurities or even harmful ingredients, and some may not contain the amount of active ingredient stated on the label.


9More cost-efficient

Food is often more cost-effective compared to supplements. While the cost of food can vary widely depending on where you live and the type of food you buy, it is typically more affordable to meet your nutritional needs through a balanced diet that includes a variety of nutrient-rich foods, rather than relying on supplements only. It is also worth stating that some supplements can be quite expensive, especially those advertised as high-quality, premium products. Also, many people may need several different types of supplements to meet their nutritional needs, this can eventually lead to significant spending.

According to Sanjay Gupta, an American neurosurgeon, medical journalist and author of the book ‘Keep Sharp: Build a Better Brain at Any Age’ eating right means eating real food, not popping pills and supplements. Supplements are not a substitute for real food and some of them can be harmful. The supplement industry is not regulated, and manufacturers have no obligation to test their products for efficacy or safety.

The evidence shows that micronutrients such as vitamins and minerals offer the greatest benefit when consumed as part of a balanced diet because all those other components in healthy food allow the micronutrients to be well absorbed and do their job better. For example, getting your B vitamins from eggs and your omega-3 fatty acids from fish trumps taking vitamins and supplements alone.

Supplements are not a magic wand. Taking supplements will not clear up the effect of all the junk food consumed. It doesn’t work like that, as much as you would like to.

Tim Spector who is a leading British epidemiologist, medical doctor, and science writer, in his book ‘The Diet Myth’, says that our obsession with the reductionist approach that isolates the one magic ingredient that can cure our ills is beautifully illustrated by our ill-fated love affair with vitamins. He advises focusing on yourself and your children and eating real food instead, which, if reasonably varied, contains most of the vitamins you need. Together with your healthy microbes, you will manufacture the rest naturally.

Your plate should be versatile and colourful, with lots of nutritious ingredients, each of which will bring benefits to you. It is much easier than you think and it is always nice to make something tasty and healthy for yourself and your family.

But if, after all this, we still cannot persuade you not to take supplements, then read on about the five, not-so-big mistakes of taking them below.

What to consider when using supplements – you can’t talk everyone out of it anyway

Because supplements are part of our lives and many of you may be taking them, our Healthypedia team decided to identify a short list of mistakes to look out for when taking them.

1Self-prescribing supplements

It is a big mistake for many people to think that if a supplement is not a medicine, they do not need to consult a doctor or take a test to check their blood levels of a particular vitamin or mineral.

Prescribing supplements without justification can lead to unpleasant consequences. For example, if you have sufficient levels of a vitamin or mineral, supplements, especially in high doses, can lead to severe allergy cases.

This is because some ingredients used in supplements, such as certain plants, enzymes or amino acids, can cause allergic reactions in some people. Symptoms of an allergic reaction to a dietary supplement may include itching, urticaria, difficulty in breathing, nausea and vomiting. In severe cases, the allergic reaction can progress to anaphylaxis which can be life-threatening.

2Neglecting quality

Of course, if the supplement you buy turns out to be of poor quality, you will need more than just adjusting your intake. In accordance with dietitian Ansley Hill, you should always choose supplements that have been third-party tested for purity and potency. This will help keep you away from consuming harmful impurities. It will also keep you from wasting money. Always check the packaging for a third-party certificate or quality seal before buying a product.

3Taking supplements at the wrong time of day

Did you know that different supplements should be taken at different times of the day?

For example, some vitamins or minerals can give you an energy boost if taken before bedtime, this will prevent you from getting good sleep. But when should you take supplements to get the most benefit? For example, vitamins A, D, E, and K: The fat-soluble vitamins (A, D, E and K) are best taken with meals. To benefit from these vitamins in the morning, you can take them during breakfast which should ideally include a sufficient amount of healthy fats. Otherwise, they can be taken during lunch or dinner.

Vitamin C supports the normal functioning of the immune system, increases energy, and is a strong antioxidant. Vitamin C persists in the body for only a few hours, so it is best to divide up your dose throughout the day.

Start taking it in the morning and set reminders so you don’t forget to take it throughout the day. Reminders for supplements, as well as medication, can easily be added to the health app.

4Taking supplements irregularly


If you take supplements irregularly, your body may constantly oscillate between optimal and insufficient intake. This will not have a positive effect on your health in the long run. If you decide to take supplements, you should take care to take them regularly and according to a daily dose.

5When you don’t read the back of the package

One of the common mistakes people make when taking supplements is not fully understanding the contents and recommended usage. Reading the label, including the ingredients list and recommended dosage, is crucial for ensuring safe and effective supplementation. In addition to the dosage of the vitamin or mineral, the words ‘other ingredients’ are written on the supplement packaging. Often, these carry hidden dangers.

The other ingredients listed on the packaging of supplements may include various additives, fillers, and binders. These are added to the product to improve its texture, stability, and shelf life.

Some common examples of other ingredients include:

1. Fillers: cellulose, corn starch, and silica are used to bulk up the product and fill the capsule.

2. Binders: gelatin, magnesium stearate, and carrageenan help hold the ingredients together.

3. Flavourings and sweeteners: artificial flavours and sweeteners are added to improve the taste of the product.

4. Preservatives: sodium benzoate is used to extend the shelf life of the product.

5. Dyes: artificial colourings which are added to improve the appearance of the product.

Let’s sum up

Taking supplements is not the same as eating a balanced diet. No chemical supplement can replace real food and its benefits for your body. Not only that, the supplement industry is barely unregulated and supplement manufacturers have no requirement to test their products for effectiveness or safety, which is frightening.

Always opt for wholesome natural food and a multi-component diet on your plate. But if you do decide to stay on the side of supplements, make sure you don’t make mistakes when taking them and always talk to your doctor as any supplement can carry health risks and a range of side effects.

Healthypedia FAQ

Dietary supplements include vitamins, minerals, herbs, botanicals, enzymes, amino acids and other dietary ingredients. You take these products orally in pills, capsules, tablets or in liquid form to supplement your diet.

‘Standardised’ means that manufacturers make sure that each batch of their products is produced in a consistent way, with the same ingredients and the same concentration of ingredients. The term usually refers to plant extracts (herbal medicines) that contain a certain percentage of the active ingredient(s). However, the term 'standardised' does not necessarily reflect the quality of the product.

Like any medicine, dietary supplements also have certain risks and side effects. That is why it is advisable to buy them with a doctor's prescription. Be careful when buying, and study the labels carefully. Pregnant/lactating women, children, and people with allergies should be more careful. If you suspect any reactions after use, tell your doctor.
