Pico Selenite® delivers stabilized selenium ions in picometer form, small enough to pass directly through cellular ion channels for full absorption at the cellular level.* Like every RnA ReSet® Liquid Mineral, this formula is built on pico-ionic technology: positively charged ions delivered in their most bioavailable form, ready for the body to use.
Selenium is an essential micronutrient that plays a crucial role in effective immune responses. Supports the structure and function of your immune system for year-round resilience and healthy immune cell activity.
Selenium is a key component of glutathione peroxidase, one of the body's most important antioxidant enzymes. Helps the body's response to oxidative stress and maintains cellular wellness.
Selenium supports cellular health through its role in selenoproteins, specialized proteins that support cellular resilience. Supports the structure and function of cells throughout the body.
Selenium is one of 9 essential minerals required for thyroid hormone production, conversion, and activation. Supports healthy thyroid function and metabolic balance.
Pico Selenite® works synergistically with ReMyte® (which contains all 9 thyroid-supporting minerals including iodine, zinc, and copper) and ReMag® (which activates thyroid hormone conversion). Together, these formulas provide comprehensive support for thyroid structure and function.*
Third-party verified for label accuracy and purity. NSF/ANSI 455-2 GMP Certified manufacturing. Made in the USA with foreign and domestic components.
Take 1 dropper (1mL) twice daily on an empty stomach, providing 350mcg of selenium total.
Why empty stomach?
Selenium absorbs best when taken without food. Try taking your first dose in the morning before breakfast and your second dose in the afternoon or evening, at least 30 minutes before eating.
What to expect:
Selenium works quietly at the cellular level. Benefits to thyroid function, immune health, and antioxidant support develop over weeks to months of consistent use. Most people don't "feel" selenium the way they feel magnesium, but the cellular support is happening.
Do not exceed 2 droppers (350mcg) daily.
Selenium has a narrower safety margin than many minerals. While selenium deficiency is harmful, excessive selenium intake can also cause problems. The 350mcg maximum daily dose from Pico Selenite® is well within safe limits but should not be exceeded.
If you're also taking ReMyte®:
ReMyte® contains 40mcg of selenium per serving. If you take ReMyte® twice daily (80mcg selenium) plus Pico Selenite® twice daily (350mcg), your total is 430mcg, which is above the adult upper intake level of 400mcg daily. Ask your healthcare provider before combining them, and count all selenium sources.
Consult your healthcare provider:
If pregnant, nursing, taking medication, or have a medical condition.
Nine minerals are required for thyroid hormone production, conversion, activation, and transportation: iodine, selenium, zinc, molybdenum, boron, copper, chromium, manganese, and magnesium.
Complete thyroid support protocol:
1. ReMag® (foundation) – Magnesium activates thyroid hormone conversion
2. ReMyte® (comprehensive) – Contains all 9 thyroid minerals including iodine
3. Pico Selenite® (targeted) – Additional selenium for T4→T3 conversion
Why selenium matters for thyroid:
The thyroid contains more selenium per gram than any other organ. Selenium-dependent enzymes (deiodinases) convert T4 to the active T3 hormone. Without adequate selenium, you may have sufficient T4 but insufficient active T3.
Note: If you take thyroid medication, talk with your doctor before adding Pico Selenite®.
Selenium and Glutathione:
Selenium is essential for glutathione peroxidase, one of your body's most important antioxidant enzymes. This enzyme helps neutralize oxidative stress and supports detoxification pathways. Without adequate selenium, glutathione peroxidase cannot function properly.
Immune function:
Research confirms selenium is an essential micronutrient that plays a crucial role in effective immune responses. Selenium supports immune cell development and function.
Brain health:
Studies show selenium is essential for the maintenance of brain function. The brain preferentially retains selenium even during deficiency, indicating its critical importance for neurological health.
For antioxidant/immune focus:
Combine Pico Selenite® with Pico Zinc® Plus (immune cell support) and Whole C ReSet® (antioxidant synergy).
What To Consider When Dosing
The thyroid gland contains more selenium per gram of tissue than any other organ in the body. Selenium is essential for the deiodinase enzymes that convert the inactive thyroid hormone T4 into the active form T3. Without adequate selenium, your body may produce enough T4 but fail to convert it to usable T3. Selenium is one of 9 minerals essential for complete thyroid hormone production and function.
ReMyte® contains 40mcg of selenium per serving as part of its comprehensive 12-mineral formula, enough for general mineral balance but not targeted thyroid or antioxidant support. Pico Selenite® provides 175mcg per dropper (1mL) for those who need higher, more targeted selenium intake. Think of ReMyte® as comprehensive mineral maintenance and Pico Selenite® as focused selenium support for specific needs like thyroid optimization or enhanced antioxidant support.
Yes, selenium has a narrower safety margin than many minerals. The adult upper intake level is 400mcg daily. The label maximum of 2 droppers provides 350mcg; do not exceed 2 droppers (350mcg) daily. However, if you're also taking ReMyte® (which contains selenium) and eating selenium-rich foods like Brazil nuts, be mindful of your total intake. Signs of excess selenium include garlic breath, hair loss, and nail brittleness. When in doubt, consult your healthcare provider.
Selenium absorbs most efficiently when taken without food. Food can interfere with mineral absorption, and taking selenium on an empty stomach ensures optimal uptake. Try taking your first dose in the morning before breakfast (or with just water) and your second dose in the afternoon or evening, at least 30 minutes before eating. However, if taking on an empty stomach causes any digestive discomfort, you may take with food, some absorption is better than none.
Selenium is a critical component of glutathione peroxidase, one of the body's most important antioxidant enzymes. This enzyme neutralizes harmful peroxides before they can damage cell membranes and DNA. Without adequate selenium, glutathione peroxidase cannot function properly, leaving cells more vulnerable to oxidative stress. Selenium also works synergistically with other antioxidants like vitamin C and vitamin E, enhancing overall antioxidant support.
Pico Selenite® delivers selenium in picometer-sized stabilized ions for direct cellular absorption. Other selenium supplements typically use organic forms like selenomethionine, which can accumulate in body proteins, or larger inorganic particles that require digestive breakdown. Pico Selenite®'s atomic-scale ionic delivery means consistent, reliable selenium absorption without digestion or accumulation concerns.
Selenium works at the cellular level, and benefits develop gradually. Unlike magnesium, which often produces noticeable effects within days, selenium's benefits to thyroid function, antioxidant status, and immune health unfold over weeks to months. Most people don't "feel" selenium directly but notice improvements in energy, metabolism, and overall wellbeing as thyroid and cellular function optimize.
