The Just Ingredients Difference

All Stage Nutrient Formula

Your thyroid is an important gland that helps control your metabolism, energy, weight, brain function, and overall health. It works as part of a system with your brain, where the hypothalamus and pituitary gland send signals to the thyroid to make hormones. Most of these hormones start in an inactive form called T4, which your body needs to change into the active form, T3, to help your cells and metabolism work properly. Our Thyroid Complex supplement provides key nutrients to support your thyroid at every step, helping your body produce and use these hormones effectively.*

The Thyroid Complex can help with:

  • Supporting thyroid hormone production*
  • Metabolism*
  • Energy*
  • Mood*
  • Weight management*
  • Mental clarity*

Does not replace thyroid medication.

Balanced Iodine and Selenium

Thyroid Support contains an amount of iodine similar to what you’d get from healthy foods, unlike some supplements with much higher doses.* While iodine is important, too much isn’t always helpful for thyroid balance.* To support healthy function, this formula also includes selenium, a nutrient that may help keep thyroid activity in a healthy range.*

Real Ingredients. Better Health.

Carefully selected ingredients for a better choice thyroid supplement. See why we included some of these key ingredients:

Iodine

Zinc

Vitamin D3

N-acetylcysteine (NAC)

Glutathione

B Vitamins

Maganese

Copper

Selenium

Iodine

Iodine is an essential mineral that the body needs to make thyroid hormones T4
and T3. These hormones are crucial for maintaining proper metabolic function,
including regulating energy and temperature.*

Zinc

Zinc plays a key role in thyroid function by supporting the body’s natural ability
to produce thyroid hormones and convert the inactive T4 hormone into the active T3 form. It also supports communication between the thyroid and the brain and is beneficial for immune health.*

Vitamin D3

Vitamin D3 helps regulate the thyroid’s function by supporting the production of thyroid hormones, which are important for metabolism. Adequate levels of Vitamin D3 are necessary for healthy thyroid function. It also plays a role in supporting the immune system.*

N-acetylcysteine (NAC)

A precursor to glutathione, an antioxidant that supports the body’s ability to protect the thyroid against free radicals. By supporting detoxification and a healthy inflammatory response, NAC helps maintain healthy thyroid function.*

Glutathione

Glutathione is an antioxidant that helps protect thyroid cells from oxidative damage. It supports the body’s natural detox processes and ability to  manage inflammation, which is important for maintaining overall health and wellness.*

B Vitamins

B vitamins are essential for overall thyroid and metabolic health. These vitamins help convert food into energy and support the production of thyroid hormones. Vitamin B6 is important for hormone synthesis, while other B vitamins, like B12 and folate, play key roles in supporting energy levels, brain function, and metabolism.*

Maganese

Manganese supports the conversion of the thyroid hormone T4 into its active form, T3. This is important for regulating metabolism and energy production. Manganese also helps protect thyroid cells from oxidative stress and supports overall cell health by aiding in the function of key enzymes.*

Copper

Copper is vital for converting the thyroid hormone T4 into T3. It also helps protect thyroid cells from oxidative damage and supports immune health. Copper is necessary for collagen production and overall cellular health, and adequate levels are necessary for proper thyroid function.*

Selenium

Selenium is an important antioxidant that helps support a healthy thyroid and immune system. It also helps promote a healthy inflammatory response, which is key in maintaining healthy thyroid function.*

Reviews

All the difference

"I love this product. It made all the difference. My thyroid labs were on the low side but in the normal range but for me it was causing some crazy symptoms. Heart palpitations being one. I started taking 1 per day and made some good improvements but not complete. When I added 2 a day it made a big difference. I am totally sold on these for me."

— Charlene J. (5/5)

Noticeable Difference in My Energy

"I’ve been taking the Just Ingredients Thyroid Support supplement for a little while now, and it’s been a great addition to my routine. I didn’t expect to feel much at first, but after consistent use I’ve noticed better energy, less sluggishness, and more mental clarity throughout the day. It feels like my body is finally running a bit smoother. I also appreciate that it’s made with clean, natural ingredients, no weird fillers or junk. It’s gentle, easy to take, and doesn’t upset my stomach like some supplements do. Overall, I’m really pleased with it and plan to keep it in my daily lineup."

— Jake B. (5/5)

These work!

"I’m on my second bottle of thyroid support and went for routine blood work for my endocrinologist. My thyroid levels results were great! My levels have been inconsistent up and down and my medication adjusted every few months. I’m so glad I’m taking these. I also feel good! These are definitely effective."

— Arias (5/5)

Works great!

"I just upgraded this to a subscription! I cannot be without it. Having Hashimoto's, I have seen a significant decrease in symptoms. Not as cold, less overall aches and pains and brain fog lifted. I settled on one capsule per day. With two I felt jittery and had headaches."

— Heidi S. (5/5)

Very helpful

"I have Hashimoto’s and my thyroid is functioning well enough that I am not currently taking medication for it. This supplement helps me feeling energized and in control of my body."

— Cooper (5/5)

Not sure about this

"I have hypothyroidism and even though I take me both thyroxine, I still feel sluggish tired much of the time. I’m almost through one bottle of this and honestly can’t tell much of a difference. I rated a four because of the high-quality ingredients. I’m just not sure if I should buy another bottle at this point"

— Shereen R. (4/5)

Great thyroid health

"Seeing better thyroid markers with this supplement I love how it has liver detox nutrients as well."

— Selina H. (5/5)

I am not sure how

"I am not sure how effective it works because I haven't been on it very long, but this keeps popping up for me to write a review. I am hoping for great results because I don't want to take a prescription for the rest of my life for this!!!"

— Nell (3/5)

Thyroid support

"I definitely noticed when I don’t take this. My mood feels balanced"

— Bills (5/5)

Thyroid support supplement

— Laura O. (4/5)

Q&A

Are the B vitamins in this particular supplement methylated?
Yes, our Thyroid Support uses methylated/cofactor forms of B2, B6, folate, and B12
Can I take this when I already take a thyroid prescription
Great question! We recommend checking with your doctor before starting any new supplement.
Would this be helpful if I don’t have a thyroid? I had a total thyroidectomy and 2 and a half of parathyroids removed. I have multiple endocrine neoplasia IIA, and medullary thyroid cancer detected. Also Hashimoto’s and hypothyroidism. ….I’m 44 and have been on levo for years. Im trying to heal my gut, support my thyroid and be as natural and clean as possible. It’s tricky when your thyroid is in the trash.
If you no longer have a thyroid, we recommend checking with your doctor before starting any new supplement. That said, our Thyroid Support still contains a blend of beneficial nutrients — including B vitamins, zinc, selenium, and more — that can support overall health and wellness, even without a thyroid. For more insight, we recommend listening to Podcast Episode 6 of the Just Ingredients podcast, where Dr. Redd shares expert advice on thyroid health and autoimmune conditions:
Took two for the first time today and a few hours later noticed my urine was neon yellow. Is this normal?
Bright yellow urine after taking supplements is often normal. For instance, the B vitamins in our Thyroid Support are water-soluble, and excess amounts are eliminated through your urine, which can cause this color change. If the bright yellow color is solely from the supplements and you have no other symptoms, it's generally harmless and simply indicates that your body is eliminating excess vitamins. However, if you have any further concerns or experience additional symptoms, please consult a healthcare professional.
Does is help with hyperthyroidism? I just had radio frequency ablation on 2 of my nodules and I'm wondering if I should take these too to help normalize things
This supplement is designed to support and regulate thyroid function—helping bring levels into balance, whether they're low or high. That said, it's always a good idea to check with your doctor, as they can provide guidance based on your individual health needs.
