great product

second time purchasing Selenoexcell and I am very happy with it. At the moment my nutrition is not the best so supplementing is a must for me! Great quality and I it is great I only need one capsule per day as I am taking other supplements too and it makes it a lot easier. It is of natural origin and this was something I needed since I have switched to non chemical supplements. If I notice any adverse symptoms I can come back to report them.

1 microgram of selenium per 1 kg of body weight This is said to be the basic calculation that can be followed. However, if you weigh more, you should not exceed the maximum possible amount, which is 200 - 400 micrograms per day. In adults, it is therefore optimal to supplement 60-150 micrograms per day. These numbers will help you if you decide to take selenium in dietary supplements. I preferred to take the capsule every other day.

Trusted selenium form with noticeable benefits

This is one of the best selenium supplements I’ve tried. The SelenoExcell form is yeast-based and well-researched, and I trust it more than generic selenium sources. I take it mainly for thyroid and immune support, and since using it consistently, I’ve felt more balanced and resilient, especially during seasonal changes. The 200 mcg dosage is ideal for daily use without going too high. Capsules are small, easy to take, and gentle on the stomach. Natural Factors always delivers clean, reliable products — this one is no exception.

Vital for thyroid endocrine system

I use selenium mainly because of hypothyroidism but I have also noticed that it has a beneficial effect on my hair and skin. I have highly sensitive and atopic skin and therefore it is of importance to take care of all the nutrients a skin needs in order to function well. My doctor said to me that I should take 200 micrograms of selenium daily in order to make sure that the thyroid system gets the needed amount.

Universal Supplement for Improving Overall Health

I have been taking this selenium supplement for a while and I am very satisfied with the overall quality. I specifically chose this brand because it uses the SelenoExcell form, which is known for its high bioavailability and excellent absorption. The 200 mcg dosage is optimal for daily immune system support and antioxidant protection. The capsules themselves are quite small, easy to swallow, and haven't caused any stomach discomfort or unpleasant aftertaste :)

Natural Factors a trusted brand

I watch Dr. Berg on Youtube and his advice has literally improved my health beyond words can even express. Selenium is a necessary nutrient and the benefits are felt. The food nowadays is deficent in selenium and Brazil nuts and supplements are the way I get the selenium that I need. The quality of Natural Factor products are always superb!
