Good quality, correct shape of selenium!

Selenium is an important trace element, and L-selenomethionine is one form of selenium that is well absorbed. I have already felt its positive influence on myself: after a week of taking it, my well-being and mood improved, and when my whole family was sick with acute respiratory infections, I was not affected. Selenium is an excellent immunomodulator. It stimulates the formation of antibodies and thereby increases the body's defense against infectious and cold diseases. It has antioxidant and carcostatic (anticancer) effects. And in general, selenium is an irreplaceable trace element for the body. I take it with organic iodine to support thyroid health. I recommend buying and drinking it in autumn, when the cold season is gaining momentum. The packaging is large, there are 200 capsules in a jar, so it will last for a long time. Capsules are small, easily swallowed, have a specific smell of medicines. According to the instructions, you need to use 1 capsule 2 times a day. Bless you! Please like this review if you found it helpful.

Positive benefits 🌱

The quality of this selenium is great! I did some research in selecting selenium to realised L-Selenimethionine is one of the best selenium for our body to absorb. The capsule is very tiny in size and easy to swallow. I’ve been taking 1 capsule a day for few weeks. I feel a good difference on my skin, hair and nails conditions. 🙏🏻

Excellent selenium supplement with a well-balanced 100 mcg dose for daily use. Easy to take, good quality, and very cost-effective for the quantity. A simple and reliable choice to support antioxidant status and overall health. Would definitely repurchase.

GOOD PRODUCT

I wanted to try Selenium for bone health since I read it can help to strengthen bones. While it's too early to tell if it is working, it doesn't upset my stomach. I've used Swanson vitamins for the last 20 years and found them to be very good.

Selenium Swanson

I have been taking the quality Swanson Selenium supplement recently as I'm trying to boost my immune function, plus improve my hair and nail health, and hopefully my skin as I suffer from psoriasis. I do think my skin has benefited from this ingredient and symptoms have calmed down since taking this mineral.

Helped me sleep.

Selenium helped me sleep. I was very much in need of this supplement. Swanson is a high quality brand and you get a lot of pills for very little money. The taste is good. The pills are easy to use. There is a strong odor but that just tells me this product is working and I did get used to it and it did not taste bad at all.

Nice value

Husband and I are both taking this in addition to our multi and prenatal to help with fertility. Be careful not to take too much selenium though and took at what your multivitamin already has! In my case I usually take this every other day. Swanson is a good value
