Dr. Tennant’s® Lugol's Iodine Plus is a complete iodine supplement solution with necessary co-factors Zinc, Selenium, B1 as well as Fulvic and Vitamin C necessary for proper iodine metabolism. 

  • Iodine supplement capsules supports hypothyroidism, proper thyroid functioning and cellular metabolism, and Iodine deficiency

  • Promotes hormone balance of all body’s hormones (not just thyroid)

Iodine is one of the few elements required for cellular health that the body cannot produce so it needs to be supplemented through food or additional nutrition.

Importantly, Iodine needs cofactors like Zinc and Selenium to work correctly; supplementation of Iodine alone will not provide the desired effect. The "Plus" of Dr. Tennant's(r) Lugol's Iodine Plus capsules has the additional factors that make Iodine usable in the body. We believe our product is the only one in the marketplace with these co-factors. 

Dr. Tennant believes your body needs both Iodine & Potassium Iodine. The thyroid gland primarily utilizes Iodide while breast tissue primarily utilizes Iodine. Different tissues concentrate on different forms of Iodine. Using a supplement that contains both Iodide and Iodine is preferable to using a supplement that contains only one form. Finally, our product contains Fulvic Acid which helps transport ingredients to all cells of the body.

MANY HEALTH BENEFITS -- our Lugol's Iodine supports the production of stomach acid, helps with fibromyalgia & migraines, improves cardiovascular health, supports healthy nails, hair & teeth, promotes hormone balance of all your body's hormones, and is necessary for proper thyroid functioning and cellular metabolism. 

ALL NATURAL - our supplements are non-gmo, contain all natural ingredients, have no sugar or artificial flavors, are hypo-allergenic, gluten & soy free, and made in the USA. Additional health benefits include:

  • Supercharges energy production
  • Strengthens & supports the immune system
  • Improves sharp thinking, cognitive focus and mental acuity
  • Helps with heavy metal & halide detoxification


90 vegetarian capsules would be a three-month supply of one capsule daily.

Lugol’s Iodine Solution – Dr. Tennant’s® Lugol’s Iodine Plus contains 2% Lugol's Iodine solution which is 5mg of Iodine and 7.5mg of Potassium Iodide.

Iodine & Potassium Iodide – The body requires iodine & iodide (like in table salt). The thyroid gland primarily utilizes iodide while breast tissue primarily utilizes iodine. Different tissues concentrate on different forms of iodine. Using a supplement that contains both iodide and iodine is preferable to using a supplement that contains only one form.

Iodine – The body’s first line of defense against infections. Iodine moves secretions from inside cells to outside cells so they can be used. Iodine is critical to making thyroid hormones and stomach acid. 

Iodine is an element found in nature and often in foods. It is critical for life, optimal cell development and is used by the thyroid and many other organs in the body to regulate mood, temperature, metabolism, cardiac health and mental acuity. 

When the body does not have enough iodine as a resource in one area (like glandular issue such as the thyroid), it will take what it needs from neighboring cells creating a deficit in those cells. This deficit causes impaired cellular regeneration and can play a critical role in the development of hormone regulation, immune support, energy regulation and autoimmune disorders at the cellular level. 

When an adequate level of iodine is present in the body, hormone regulation, immune system function and cellular generation are made possible.

Cofactors – Selenium, Zinc, B1 and Vitamin C are necessary for proper iodine metabolism. Dr. Tennant’s® Lugol's Iodine Plus also provides Fulvic Acid which helps transport iodine to all the cells of the body, along with macro, micro and trace minerals.

Seems fine

Fine. I purchased this on advice from my practitioner. I cannot tell that it's helped but it hasn't harmed me either! I'm a poor person to ask. I find, though, all products sold here are the best!

I take it faithfully everyday and I went from getting sick a few times a year to not getting sick since I started.

A Critical Supplement

My family lived in an area very low in iodine. As a result, my grandfather had to travel from Canada to the Mayo Clinic to have his goiter removed in 1917. He was so elated, he fathered my mother, and we all had different thyroid conditions. Dr Tennant found and treated my faulty T4 conversion problem. I take this supplement daily and truly enjoy life now!

Excellent product...too expensive now

This product was offered by the thermography center I go to. Definitely noticed improvements with breast and thyroid health. It was affordable when I started buying 3-4 years ago but they have had an exponential price increase this year which puts it out of my price range now. I wish it was more affordable. I am taking another product but it does not have all the co factors.

1st Trimester: Immediately stopped Nausea & Fatigue

This is my 2nd pregnancy and I was experiencing extreme fatigue. I felt like I had mono to be honest. I was also throwing up everyday, sometimes multiple times a day. I was worried about getting enough fluids, nutrients, etc. Because I just couldn't keep anything down. My quality of life ******. I wasn't getting out of bed. Almost immediately after using the recommended iodine & restore (vegetarian) supplements, I felt like a completely new person. Not only am I now energized, but I haven't even gotten the urge to throw up. I'm now waking up before my husband with our 7 month old just ready to go. What a game changer for me and I will never not be using it!
