Casida selenium drops – easy to dose & highly bioavailable
The Casida selenium drops provide high-quality sodium selenite in pure, liquid form – ideal for daily supplementation of selenium levels. Due to the liquid form, the trace element is particularly easy to dose and is quickly absorbed by the body.
Especially pure composition
Only three ingredients: Water, sodium selenite, and right-handed lactic acid. Free from additives, flavors, or preservatives.
Easy to use
The drops can be precisely dosed – pure or diluted in water. This makes daily selenium intake particularly uncomplicated.

For the immune system, thyroid function, cell protection, hair, nails, and sperm production.
Selenium is a vital element that often cannot be absorbed in sufficient quantities through food. Selenium protects cells from oxidative stress and contributes to maintaining immune function and normal thyroid function. Sodium selenite (inorganic selenium) is absorbed more quickly by the body and is therefore the acutely bioavailable form of selenium.
Selenium – Why It's So Important
The body's own metabolism cannot produce selenium; therefore, it must be supplied daily in sufficient quantities through food. Selenium is found in all cells and is an essential component of numerous enzyme functions. These enzymes perform essential functions in the body and are active when cell protection is activated to scavenge free radicals.
In this context, selenium contributes to protecting important components of the cell, such as genetic information, from oxidative damage. A sufficient supply of selenium is also important for the normal function of the immune system and the thyroid gland. Selenium also contributes to normal sperm development, as well as to the maintenance of normal hair and nails.
Selenium – an important supplement
Nutrition should be the top priority. Therefore, selenium and other vital substances should be present in sufficient quantities in food.
To be on the safe side with your selenium supply, it is recommended to supplement your daily diet with a selenium supplement. Our body needs selenium especially during periods of high physical exertion, stress, old age, pregnancy, and breastfeeding, and can often not get enough of this micronutrient.
In addition, certain population groups (e.g., people with chronic metabolic and digestive disorders, vegetarians, vegans) often consume too little selenium.
