Truth or Myth: Important Information Behind Vitamins and Nutritional Supplements

Everywhere you can find recommendations on nutritional supplements and foods that supposedly improve blood pressure, increase energy levels in the body or protect the brain and immune system from all kinds of malicious factors. But a recently published scientific review has refocused attention on what the science really says, distinguishing between real benefits and common exaggerations designed just to sell products or generate interest and buzz.

Zinc and blood pressure: a conditional benefit

Experts warn against relying on zinc supplements as a substitute for medication or lifestyle changes, such as reducing salt intake and increasing physical activity – actions that are usually recommended for those with high blood pressure. Excessive zinc intake may also cause drug interactions or interfere with the absorption of copper, another essential element for the body.

Eggs and brain health support

Kimchi and the immune system

Kimchi, a traditional Korean dish of fermented cabbage, not only supports gut health – but may also strengthen the immune system. A small study found that its consumption improved the activity of certain immune cells in overweight people. However, experts warn of the need for caution among people suffering from high blood pressure, due to the high sodium content of this food.

Vitamin D and chronic fatigue

Omega-3 and blood sugar: limited facts

The researchers emphasize that controlling blood sugar requires medical treatment and ongoing changes in lifestyle, such as a balanced diet and physical activity, rather than relying on a single nutritional supplement.

In conclusion, experts say these results confirm that nutritional supplements can be beneficial, but their benefits are neither universal nor automatic. The basic principle remains accurate diagnosis, moderation and linking each supplement to a healthy lifestyle under medical supervision, while avoiding hasty and unfounded promises.
