Do you feel tired for no reason? Are you losing more hair than usual or is your skin looking gray? Before looking for complex solutions, there may be a message your body is trying to send you.
Because no, vitamins aren’t just a checkbox on a diet app. They are everywhere, and when they run out, you feel it in every fiber of your body even if you don’t know it yet.
What are vitamins really for?
You may have already been told that they are “essential”, without explaining why. Vitamins are not an option: they are involved in hundreds of vital chemical reactions. Without them, your body slows down, your metabolism slows down, and your mood takes a hit.
There are 13 essential vitamins, classified into two large families: those soluble in fat (A, D, E, K) and those soluble in water (C and group B vitamins). The first category is stored in your liver and fatty tissues, the second is eliminated daily – so you need to consume it every day.
Each vitamin has its specialty. Vitamin D helps your body fix calcium, B12 supports your nervous system, A takes care of your vision, K plays on coagulation… Suffice it to say that if one piece of the puzzle is missing, your entire balance is disrupted.
Signs that you are lacking vitamins
Most deficiencies do not appear suddenly. They move slowly, often confused with fatigue, stress or the change of season. Here are some red flags to look out for:
- Persistent fatigue, even after a good night’s sleep
- Unusual hair loss
- Brittle or ridged nails
- Gums that bleed easily
- Frequent cramps
- Feeling of heavy legs
- Red patches or very dry skin
- Difficulty concentrating
- Irritability or low morale
Where to find vitamins in your diet?
Good news: you can cover almost all of your daily needs by eating a varied and balanced diet. Food supplements are not always necessary, except in the event of a proven deficiency or special situation (pregnancy, veganism, age, etc.).
Here are some examples of natural sources for the main vitamins:
- Vitamin A: liver, butter, eggs, carrots, spinach
- Vitamin B1: whole grains, legumes, pork
- Vitamin B6: banana, chicken, potato
- Vitamin B12: animal products only (meat, fish, eggs)
- Vitamin C: citrus fruits, kiwi, pepper, parsley
- Vitamin D: sun (synthesis by the skin), fatty fish, egg yolk
- Vitamin E: vegetable oils, oilseeds, avocado
- Vitamin K: leafy green vegetables, broccoli, cabbage
The most common deficiencies… and their risks
In France, several studies show that certain deficiencies have become common. It is not a question of malnutrition, but often of a sedentary lifestyle, industrial diet and lack of exposure to the sun.
- Vitamin D: More than 80% of adults in France have a deficiency in winter. However, it is essential for immunity and bone health.
- Vitamin B9 (folate): Crucial in pregnancy, it is often insufficient in women of childbearing age.
- Vitamin B12: Vegans or elderly people are particularly at risk.
- Vitamin C: Although it is thought to be omnipresent, it can quickly be lacking in smokers or in the event of a diet poor in fresh fruit.
Do you really need to take supplements?
Not necessarily. The vitamin capsule business is worth billions, but it does not replace real food. Supplements have their place, but only if your doctor or a blood test reveals a deficiency.
The danger is blind self-medication. Too much vitamin A, D or E can be toxic. And some interactions with medical treatments are not trivial.
So before throwing yourself at a colorful box sold in pharmacies, start by looking at your plate… and at your routine. Getting some fresh air, moving more, and cooking raw products already work miracles.
FAQ – We tell you everything about vitamins
1. Are vitamins in capsules as effective as those in food?
Not always. Natural vitamins from food are better absorbed by your body. Food supplements can help, but they should never replace a varied and balanced diet, except in cases of proven deficiency.
2. What are the best brands of vitamins to buy at the pharmacy?
Certain French brands such as Juvamine, Nutergia or Phytalessence are recognized for the quality of their formulations. For targeted deficiencies (such as vitamin D), brands like Zymad (often prescribed) or D.Plantes are often cited. The important thing is to choose well-dosed products, with a clear composition and without unnecessary additives.
3. Can we combine several vitamins without risk?
Yes, to a certain extent. For example, multivitamin complexes are designed to be balanced. But be careful of overdosing with fat-soluble vitamins (A, D, E, K) which can accumulate in your body. Before combining different supplements, it is better to seek advice from your doctor or pharmacist.
4. How long does it take to feel the effects of a vitamin treatment?
It depends on your initial situation. If you are really deficient, an improvement may be felt after 2 to 4 weeks. But vitamins are not instant boosters. Their effect is progressive, and is mainly observed over time (energy, sleep, immunity, etc.).
5. Are vitamin gummies as reliable as regular tablets?
Gummies are more pleasant to consume, especially for those who have difficulty with pills. Their effectiveness depends mainly on the dosage and ingredients used. As long as the composition is serious and well formulated, they can be a good alternative – but not an everyday candy.
