Recommended dosage

"Recommended dose" refers to the amount of a particular substance, such as vitamins, minerals, proteins, fats, or carbohydrates, that a person should consume daily to maintain optimal health. These values are determined based on scientific research and may vary depending on age, gender, body weight, pregnancy, and other factors. Recommended doses are commonly listed on the packaging of food products and dietary supplements to help consumers understand how much of each substance they should ingest daily. However, these doses are indicative and can vary according to an individual's needs. Significant exceeding of the recommended dose can, in some cases, lead to adverse effects.

Hello,

Do I understand correctly that quercetin cannot be consumed in diet in amounts that match supplementation levels? Let's say in a regular diet it's 50 mg, in specialized diets more, but not 500 mg? And in this case, does supplementation always make sense?

Under normal conditions, it is essentially impossible to consume such a high amount of quercetin on a daily basis, which is where supplementation has its clear significance. This is a typical example of the role dietary supplements can play in the quality of nutrition.

Hello,
I am curious to know whether it is possible to overdose on iodine from natural sources (I recently developed a taste for dried nori seaweed, which seemed like a great alternative to chips, but I found a recommended dose of max 3 pieces per day on the back, otherwise there is a risk of iodine overdose)? And what would be the symptoms of an overdose?
Thank you for your response.

Overdose of iodine is a rare occurrence. The element binds to salts that are water-soluble—the body has mechanisms to eliminate its excess. If you do not suffer from hyperthyroidism, a higher intake of iodine should not be harmful (at least not in short-term cases).
