What is Mustard Seed?
Mustard Seed is essential to stay healthy because it's packed with selenium. Selenium's central role is to support the thyroid and help it use iodine and produce hormones. It's also necessary for a strong immune system, healthy cardiovascular function, and efficient metabolism. Despite its importance, it’s easy to fall short on your selenium intake when relying on food alone. A natural, high-quality selenium supplement is the answer.
That's why we created an all-natural, plant-based formula made with selenium extracted from certified organic mustard seeds. It's perfect for ensuring that you consistently get the bioavailable selenium you need to support your health and wellness. Every bottle contains 60 capsules and lasts two months when used as directed.
Health Benefits of Selenium
Selenium is an essential nutrient that supports many of the important processes in your body that keep you healthy.

Thyroid Support
Selenium helps ensure normal thyroid hormone levels. It’s also used to produce glutathione peroxidase, an antioxidant enzyme that protects the thyroid.

Immune Booster
Your immune system can only help you if it’s strong, and selenium can help. As an antioxidant, selenium helps neutralize free radicals and support white blood cells.

Healthy Metabolism
If you’re trying to lose weight but your metabolism says no, selenium could be the tune-up you need. Supporting the thyroid encourages normal metabolic function.

Why Mustard Seed Canada Is Different
For supporting a healthy thyroid, immune system, and more, our natural, plant-based selenium supplement is as good as it gets.


Plant-Based Formula
Our vegan-friendly selenium is extracted from organic mustard seeds, a vegan-friendly source of selenium that even provides other nutritional cofactors and co-nutrients to help the activity of the selenium. No artificial ingredients or additives of any kind.
Synthetic
Most selenium supplements are made with selenium that’s produced synthetically in a lab and contain toxic additives like magnesium stearate. These unnatural forms are rough on the digestive system and aren’t efficiently absorbed or used by the body.
Direct From the Manufacturer
We make selenium at our state-of-the-art manufacturing facility in Phoenix. You’re getting it right from the people who make it and carefully manage its handling from start to finish. No long time spent in transit, no time spent in hot warehouses.
Unknown Origin
The reality is that very few nutritional supplement companies make their products. Rather, they all purchase the same bulk-produced pills from no-name factories and have no control over any aspect of production except for the label design.
Neutral Odor
Our selenium supplement is the easiest to take and a big reason is because the capsules have a light, natural odor. They’re not overwhelming and won’t send your sinus passages into a shock.
Smells Horrible
Read the reviews. A common complaint of many selenium supplements is that they have a strong odor that’s similar to rotten eggs and sulfur. What good is a supplement if you can’t stand to take it?
Tips for Taking Mustard Seed
Supplement With Iodine
Mustard seed and iodine are the perfect match. An iodine supplement like Organic Nascent Iodine provides the nutrition you need to encourage a healthy thyroid.
Take It Consistently
Selenium is a trace mineral and we only need a small amount of it. However, because it plays many important roles, our bodies use it quickly.
