Benefits of selenium for skin health and how to use it

Selenium is one of the trace minerals that, although the body only needs it in small amounts, plays a crucial role in maintaining health. It acts as a powerful antioxidant, helping protect cells from damage, and is essential for a strong immune system and proper thyroid function. However, like any nutrient, balance is key! A deficiency can cause problems, and excess intake can be harmful. In this medical guide, we will explore its types, benefits, and the groups that may be more prone to deficiency.

Types of Selenium

Organic Selenium (Easier to absorb and more beneficial to the body)

Selenomethionine
The body absorbs it quickly and efficiently.
Found in nuts, whole grains, and meats.
It’s the most commonly used form in dietary supplements.
Selenocysteine
Found in protein-rich foods like eggs and meats.
Plays a key role in enzymes that fight oxidation.

Inorganic Selenium (Lower absorption, but beneficial in appropriate doses)

Sodium Selenate
Used in some medications and research to treat nerve diseases.
The body converts it into an active form of selenium.
Sodium Selenite
Taken as a dietary supplement, but its absorption is lower than selenomethionine.
Can be used to treat selenium deficiency in the body.

Groups at Risk of Selenium Deficiency

People with digestive issues
- Patients with Crohn's disease and ulcerative colitis, as their bodies struggle to absorb minerals.
- Those who have had surgery on the stomach or intestines, such as bypass surgery.
- People relying on intravenous nutrition for extended periods due to digestive problems or absorption issues.
Kidney patients undergoing dialysis
Dialysis reduces selenium levels in the blood.
People living in areas with selenium-poor soil
Some regions, such as parts of China and Europe, have selenium-deficient soil, so the food grown there is not rich in it.
Immune-compromised patients, especially those with HIV/AIDS
Selenium helps strengthen the immune system, and people with HIV/AIDS are often deficient in it.
People with a diet poor in selenium
- Strict vegetarians, especially if their food comes from selenium-poor soil.
- Those suffering from malnutrition or following a very restrictive diet.

Selenium Components

Selenium is not a complex chemical compound, but a natural element found in the soil, water, and some foods. Let's break down its components scientifically and nutritionally.

Chemical Composition of Selenium
- Chemical symbol: Se
- Atomic number: 34
- Classification: Non-metal
- Color: Grayish-silver (in its pure form)

Selenium naturally occurs in different forms, such as:

Organic Selenium: Found in foods like Brazil nuts, fish, and eggs.
Inorganic Selenium: Found in some supplements in the form of sodium selenite or sodium selenate.

Components of Selenium Supplements
Selenium supplements vary in type and composition. The most common forms include:
- Organic Selenium (better absorption)
  - Selenomethionine (L-Selenomethionine)
    The form the body absorbs easily and benefits from.
    Found in both animal and plant-based proteins.
    Stored in the body for a longer period.
  - Selenocysteine
    Found in foods like garlic and onions.
    Part of enzymes that protect cells from damage.
- Inorganic Selenium (weaker absorption)
  - Sodium Selenite
    Found in some dietary supplements.
    The body absorbs it slowly compared to organic selenium.
  - Sodium Selenate
    Rarely used, but important in certain medical treatments.
Nutrients that Enhance Selenium Absorption
Selenium doesn’t work alone; it interacts with other minerals and vitamins to improve absorption, such as:
- Vitamin E → Enhances selenium's antioxidant activity.
- Zinc → Helps improve its absorption and strengthens immunity.
- Amino acids → Such as methionine and cysteine, which improve absorption.
Foods Containing Selenium
- Animal-based sources:
  - Fish (salmon, tuna, sardines)
  - Eggs
  - Liver and red meats
  - Dairy products
- Plant-based sources:
  - Brazil nuts (the richest natural source)
  - Whole grains (oats, brown rice)
  - Legumes (lentils, beans)
  - Garlic and onions

Recommended Daily Selenium Dose

Men and women: 55 micrograms per day
Pregnant women: 60 micrograms per day
Breastfeeding women: 70 micrograms per day
Safe upper limit: 400 micrograms per day (exceeding this can lead to selenium toxicity).

Benefits of Selenium for Skin

If you're not getting enough selenium from your food, you can opt for supplements, but it's important to consult a doctor to avoid any health issues.

Best form of supplements:

Selenomethionine (L-Selenomethionine) because it's easily absorbed by the body.
Recommended daily dose: 55 micrograms for adults.
Warning: High doses (more than 400 micrograms per day) can cause issues like hair loss, skin irritation, and bad breath.

3. Skincare Products Containing Selenium

4. Tips to Enhance Selenium Absorption in the Body

Take it with Vitamin E, as it improves absorption and effectiveness as an antioxidant.
Drink plenty of water to keep your skin hydrated and boost mineral absorption.
Limit processed foods, as they reduce selenium levels in the body.
Pay attention to your sleep and mental health, as stress can affect mineral absorption.

5. Precautions When Using Selenium

Nerve damage (in severe cases)

Solution: If you experience any of these symptoms, stop taking selenium immediately and consult a doctor.

Drug Interactions
Selenium can interact with certain medications, so be cautious if you're taking:

Anticoagulants (like aspirin and warfarin) – it can increase the risk of bleeding.
