Tips for choosing the right selenium supplements for you
Form
Organic and inorganic are two forms of selenium. Organic forms include selenomethionine, methyl selenocysteine, and selenium. Inorganic forms include selenite and selenate. Organic and conventional forms are useful, but organic versions are more effective since the body can keep them better. Most of the best selenium supplements in USA are organic.
Certified
Make sure your supplement is third-party verified. Supplements that have been third-party tested are taken to a lab for testing. It ensures that they contain what they claim and do not contain high-risk, common contaminants. ConsumerLabs, NSF, and USP are three third-party certifications you can trust.
Ingredient
If you’re going to buy a supplement, make sure you read the label carefully. Selenium supplements typically contain gelatin capsules and selenium, while some may also include proprietary mixes, which combine trace amounts of fruits and vegetables with other vitamins.
It’s crucial not to pick a selenium supplement with a proprietary blend because it might not have more helpful elements. In addition, it is typically present in inadequate amounts to make a significant difference.
Check the supplement’s label to ensure it doesn’t include any common food allergies. For example, if you’re allergic to yeast, selenium pills containing yeast may cause you to react.
Whole food VS synthetic supplements
Whole food supplements contain actual fruits and vegetables, whereas synthetic supplements are prepared in a lab. Some people claim that synthetic supplements are just as effective as whole food supplements and are more natural.
If you prefer to get your selenium from whole foods, you will need to take more pills to get the same amount, but synthetic supplements have more selenium per serving.
Liquid VS Capsule
If you choose a capsule, check the label for the capsule per serving. It ensures you are getting the required quantity of selenium. Some capsules may not be vegan, vegetarian, or gluten-free. If you follow one of these diets, make sure the capsule doesn’t contain any gelatin that you can’t eat.
Liquid supplements serving size is measured in drops. So you’ll need to be comfortable using a dropper to acquire the right amount. In comparison to capsules, one disadvantage of liquid is that it may have an unpleasant taste that some people dislike. Look for reviews to see if anyone has mentioned any strange flavours they’ve had.
Capsule size
Swallowing large selenium supplements can be challenging. If you know this will be a problem for you, find out the size of the capsules before you buy them. Manufacturers frequently list the capsule size on the label, so you know exactly what you receive before buying.
Odour
Although selenium has an unpleasant odour, some supplements disguise it better than others. A person with a highly sensitive sense of smell may find it hard to take.
Expiry date
Check the supplement’s expiration date and ensure it has a long shelf life. It should be up to 18 months after the date of manufacture. Do not buy a supplement that expires within a month or two.
