Analysis
Vital Nutrients Selenium is listed as 200mcg but actually delivers a total of 800mcg of selenium per serving, combining 400mcg of Selenomethionine (an organic form) and 400mcg of Sodium Selenite (an inorganic form). This extremely high combined dosage is far beyond the typical daily supplemental intake and the established upper intake levels for selenium. While Selenomethionine is well-regarded, the inclusion of Sodium Selenite and the overall quantity are notable.
This supplement is not intended for general daily use due to its potent concentration. The significantly high dose of selenium could potentially lead to adverse effects if taken without careful monitoring. It is a product that requires explicit professional recommendation and supervision, given the dosage discrepancy and the combination of selenium forms.
Pros
- Includes Selenomethionine, a well-regarded organic form of selenium.
- Clearly lists both forms and quantities of selenium present.
Cons
- Extremely high total selenium dose (800mcg) per serving.
- Product name 'Selenium 200 mcg' is misleading given the 800mcg actual dose.
- Includes Sodium Selenite, an inorganic form that may be less preferred than organic forms.
- Very high price per serving compared to common selenium supplements.
Warnings
- The total 800mcg selenium dose is significantly above typical safe upper intake levels and poses a risk of selenium toxicity.
- This product is only suitable for use under the strict guidance and supervision of a healthcare professional.
- Do not take this product without consulting a medical professional, especially if pregnant, nursing, or with existing health conditions.
- Potential side effects of excessive selenium include hair loss, nail brittleness, skin rash, and gastrointestinal upset.

Goals
Impact
Moderate effect
While selenium is vital for immunity, there is an optimal range, and extremely high doses can potentially disrupt immune function rather than enhance it. This dosage is likely beyond the beneficial range.
Impact
Moderate effect
While selenium supports detoxification as an antioxidant, an excessively high dose can potentially overwhelm the body's systems rather than optimally support them. The extreme dosage raises concerns about balance.
Impact
Moderate effect
Selenium is crucial for thyroid function and metabolism. However, excessively high doses can impair thyroid hormone synthesis and lead to thyroid dysfunction, making it counterproductive for metabolic health.
Impact
Moderate effect
While selenium is an antioxidant, excessive amounts can sometimes act as pro-oxidants or disrupt cellular balance, potentially leading to adverse effects rather than anti-inflammatory benefits.
Impact
Moderate effect
Selenium supports heart health at appropriate levels, but excessive intake can potentially lead to cardiac issues or other systemic toxicity, making this dosage unsuitable for promoting cardiovascular health.
Impact
Moderate effect
Excessive selenium intake can be toxic and may pose risks to cardiovascular function, potentially counteracting any benefits seen at lower, appropriate dosages. This is not suitable for general cardiovascular support.
Impact
Lower effect
Extremely high doses of selenium can be toxic and may lead to various health issues, including those that could indirectly impact vision negatively. This product is not suitable for vision support.
Impact
Lower effect
While selenium plays a role in reproductive health, extremely high doses can be detrimental to overall endocrine function and may lead to adverse effects rather than supporting testosterone levels.
