Testimonial

"This product is fantastic. I feel noticeably more energetic, less brain fog, and have even lost a little weight without trying. I trust Thorne from using their other items, so I choose their brand when I needed this supplement. I have Mthfr, and with each pregnancy I must be monitored closely to help avoid miscarriage, which I've had 3 before they began giving me special methylated folate, and b vitamins. But every time they test my thyroid (because low thyroid can also trigger a miscarriage) it is always just barely in the OK zone, via the convential test. So I assumed I would have a low thyroid if they test t3 and the other recommended tests that a functional medicine doctor would order. So after my recent pregnancy I noticed the hair loss begin, and the brain fog set in strongly, so I ordered this product.

I was honestly surprised at how amazing this made me feel. I didn't realize I was experiencing aches, but now that they're fading I noticed how much better I feel." - Patty

Testimonial

"I have used Pure Encapsulations since the early 1990's. Pure Encapsulations is on of the few OTA supplement companies who make and provide clean bioavailable supplements. Meaning they use minimal fillers and only fillers that the body needs and absorbs. Many minerals need to be either chelated (bound to an amino acid) or be in citrate form in order for the body to be able to absorb the mineral and therfore, actually get results of the mineral to the cells and tissues in the body need. For minerals I would suggest looking for and using only Pure Encapsulations, or Thorne Research. There are a few good other companies, but the above mentioned companies have a wide variety of trusted supplements. Also try to look for chelated or citrate bound mineral to ensure your body is able to absorb your minerals so you can feel and reap the benefits." - Aneesha L. McClure

Testimonial

"I was looking for a concentrated selenium product that wasn't 99% fillers, and that also didn't have unhealthy fillers, like magnesium stereate or sodium benzoate. I also wanted the product to be concentrated and therefor last a while, and also be in an absorbable form. This product met all those requirements. I'm megadosing on Iodine and taking 150mg or so a day. If this selenium wasn't being absorbed I would feel terrible as Iodine requires selenium for proper use. I take half the recomened amount for this product and I feel great" - Hunter

Testimonial

"When your target is to boost your immune system-natural selenium is the answer. Can be consumed by a perfectly healthy person up to 1-2 mg a day, for that I usually use 4 capsules of this supplement and 5-10 organic brazil nuts a day! Don't worry about overdose, as long as you use natural selenium like this one -> SunFarm Organics Organic Selenium, you are good! At all costs, AVOID widely popularized L-Selenomethionine because it's ineffective and toxic at high doses! INatural Selenium is a MUST HAVE supplement for cancer patients, especially those going through a chemotherapy, just need to double the dose! Recommended by Conrad LeBeau. For more info about health read: Immune Restoration Handbook by Conrad LeBeau (I purchased mine on Amazon too!). This is my second bottle of SunFarm Organics Organic Selenium and I'm consistently happy with my purchase!" - Ganna Shapoval

Testimonial

"Wow, this selenium is great. I got burned by an ex-ray and thought this organic selenium might help repair my skin. After only a few weeks of using this selenium & a few other supplements the burn is healing well. An unexpected benefit has been for my nails. Toe and finger nails are looking really good. Ridges are smoothing out and the nails are shiny again. My nails have always been very weak and thin. Now they are hard. I will continue to take Global Healing Center Organic Selenium." - ML

8. Nested Naturals Selenium Supplement

Features & Benefits

• Over 152+ Positive Reviews
• AN OPTIMAL DAILY DOSE OF ANTIOXIDANTS: Selenium is a stellar source of antioxidants. Antioxidants help maintain proper balance in your body by neutralizing free radicals.
• SUPPORT THYROID FUNCTION & CARDIOVASCULAR HEALTH: The largest concentrations of selenium are found in the thyroid. Selenium powers enzymes that convert the thyroid hormone T4 into T3 to play a role in your growth, temperature regulation, and metabolism, as well.
• HIGHER ABSORPTION: Selenium is an essential mineral, but can be difficult to digest depending upon what it bonds to. We chose the more bioavailable L-Selenomethionine for better absorption over selenate and selenite forms.

Testimonial

"Selenium is a nutrient that the body needs to stay healthy and is important for reproduction, thyroid gland function, DNA production, and protecting the body from damage caused by free radicals and from infection. This is a super supplement that acts as an antioxidant, reduces the risk of cancer, protects against heart disease, helps prevent mental decline, boosts the immune system, and also may help reduce asthma symptoms. As there aren’t a lot of foods that accumulate much selenium, even if they are grown in selenium-rich soil, many are selenium deficient. Supplements are an effective way to get this essential nutrient. Love this line since it's also vegan, formulated with no additional nutrients. and created with maximum bioavailability and easy digestion in mind." - Audrey

Testimonial

"I have taken other brands of selenium in tablet form and found them very difficult to swallow. These capsules are far superior and much easier to take. Just what I was hoping for. Order came very promptly. Will definitely order this brand again. It's also soy, gluten and dairy free which is important to me in selecting a supplement." - nightingale RN

Testimonial

"I'm so glad I bought this. I began to realize the symptoms I was experiencing could be from an unsupported liver that was essentially getting bogged down with all the junk we encounter daily. I had a very serious symptom that was continuous for 6 months or more. I was told selenium would be good for liver support and help it detox itself as it should, and after 2 weeks taking this the major symptom is completely gone. Feels like a miracle. I don't feel like many people get to experience the joy of health actually improving so dramatically. I couldn't be happier." - Bethany Perkins
