Suffering From Infertility? Taking the Right Amount of Selenium Could Be the Solution

There are many essential minerals that are needed in small amounts but play an important role in several bodily functions. Selenium is one such mineral which is an absolute must for the proper functioning of our body. Let’s talk about this important mineral and how it can prevent us from several diseases.

Why is selenium crucial for health?

Selenium is a vital mineral that is found in abundance in the soil. It also naturally appears in food and water. Though we need less amount of selenium as compared to vitamins and other minerals, this micronutrient still holds an important place. Below pointers will help shed some light on the significance of selenium.

Rich source of anti-oxidants

Selenium is known for its excellent anti-oxidants properties which boost the immune system against free radicals and help fight aging process. It also defends against some cancers including colon, rectal and prostate.

Boosts fertility 

Selenium is the ingredient necessary for proper motility of sperm and increment of blood flow. These two major components play a crucial role in conception. Selenium is integrated into the sperm cell and may change the functioning and behavior of the sperm as it travels through the vaginal canal.

Reduces symptoms of asthma 

Various studies suggest that people with asthma have low level of selenium. And when these people were given selenium supplements, their symptoms improved.

Helps in regulation of thyroid 

The thyroid performs several everyday functions including metabolism, appetite, sleep, and temperature among others. According to some studies, there is a strong link between thyroid function and deficiency of selenium. It protects the thyroid from antibodies that could give rise to various thyroid diseases including Grave’s disease and Hashimoto’s disease.

Boosts immunity 

Selenium is extremely necessary for the adequate functioning of our immune system. It can also act as a protective shield against the development of viruses. In some studies, giving dose of selenium to patients with HIV has shown positive results in slowing down the progression of HIV into aids.

Prevents heart diseases 

A rich selenium diet may also help in keeping the heart healthy. It fights inflammation, increases blood flow and cut the risk of getting coronary artery disease.

How much selenium is required for our body?

Selenium deficiency is uncommon around the world as most people can get selenium from their everyday diet. Below is the daily recommended allowance (RDA) for selenium:

Infants

  • Birth to 6 months – 15 microgram/day
  • 7-12 months – 20 microgram/day

Toddlers and children

  • 1-3 years of age – 20 micrograms/day
  • 4-8 years of age – 30 micrograms/day
  • 9-13 years of age – 40 micrograms/day

Teenagers and adults

  • 14 years and above – 55 micrograms/day

Pregnant and breastfeeding women

  • Pregnant women – 60 micrograms/day
  • Breastfeeding women – 70 micrograms/day

What are the health risks of low selenium or overdose of it?

Most people are advised to get their nutrition from the food itself. And rather concentrating on a single nutrient, one should include variety of nutrients in a well-balanced diet. Selenium does not have any side effects if it is taken within the tolerable range. According to experts, the safe upper limit of selenium is 400 micrograms (mcg). Anything above this figure is considered an overdose.

Too much of selenium can cause fever, bad breath, nausea, joint pain and create problems in liver, kidneys, and heart. This happens by consuming large amount of selenium. As a result, it can give rise to selenium toxicity or selenosis. The selenium can also interact with certain drugs and supplements and cause problems.

Selenium deficiency on the other hand, can also inflict a range of symptoms including fatigue, muscle weakness, hair loss, infertility in both men and women and weak immune system. Selenium-rich diet can help prevent these symptoms.
