Instead of taking just Levotheroxyne and other medications that are prescribed by doctors, I highly recommend researching more for healthy ways to improve your thyroid health. My best two supplements are thyroid health formula and iodine. Check my thyroid every 2-3 months in dynamic. Those supplements have lowered my TSH and my doctor lowered the dosage of my medication. And she was mad about it 😂

The combination of herbs, minerals and vitamins such as selenium, iodine plus ashwagandha is fantastic in this mix. The price is great compared to other formulas of a similar nature, and I find this brand just as effective. This is also lab verified for efficacy and active ingredients, which is a huge plus. Hope this helps, peace to all

Good for mood and energy

Good ingredients and convenient packaging - I take 2 capsules in the morning, and it seems to improve my mood. Some days it takes 2 caps twice a day. As we age thyroid often becomes slow, so supplements help, along with more vegetables, no gluten, milk protein and more iodine... God helps to find the right path to health.

Seeing results

My thyroid was a bit inactive and I was putting on weight so I bought these to help. The benefits are that I’m losing a bit of weight and I feel much better in myself. The quality is good but they have a strange smell. The price is good and so is the quantity.

Good Quality 💚

Natural Factors Thyroid Health Formula is a high-quality supplement with well-chosen ingredients to support overall wellness. The blend includes key nutrients and herbal extracts, making it a well-rounded option. The size of the bottle (60 vegetarian capsules) is convenient, and the dosage is easy to follow. I’ve noticed a positive effect since incorporating it into my routine, especially in terms of energy and balance. One of the benefits I appreciate is that it’s gentle and easy to digest. As for the taste, the capsules have no noticeable flavor, which makes them easy to take daily. Overall, this is a solid supplement for those looking for a high-quality thyroid support formula with carefully selected ingredients.

2 caps per day

I don't know about efect on thyroid but from my own experience 2 caps per day is for me personally too much. I've tried L-tyrosine, that is one of the incredience in this supplement, separately and I can't take more than 500mg every second day as otherwise I feel like my brain is in buzz. But other than that I take this supplement at the moment one capsule every day, so it should give me 250mg L-tyrosine and I feel grand. No buzz-side effects. Will see if it helps with weight loss also as with hypothyroidism I've been struggling to get back to my normal weigh, but if I see improvement overall health, then should be easier also to get up and do something to lose weight.

Great Product

I am hypothyroid and normally take Armour Thyroid at 90mg per day. My prescription lapsed and I didn't have insurance for a time and tried this product. I will say that it fit the bill and kept me alert and I felt as though I was still on my thyroid prescription. So I would definitely recommend.

Took a couple of these with breakfast, and they’ve subtly supported my daily rhythm—no energy rollercoaster, just a gentle steady vibe. Capsules are mild and digest well, even on an empty stomach.
