What customers say
Customers highly praise the MegaFood Thyroid Strength tablets for their high-quality, natural ingredients and effectiveness in supporting thyroid health. Many users report increased energy levels and overall well-being after consistent use. The product is particularly beneficial for those with hypothyroidism or borderline thyroid issues, with some customers noting they could reduce or eliminate their prescription medications. Despite the tablets being slightly large, users appreciate the ease of incorporating them into their daily routines. The product has been used successfully by many for several years without side effects, and it is recommended by some doctors as a supplement to thyroid medication. Quick delivery and good packaging are additional positives noted by customers.

Like the variety of ingredients and great quality as the product is made from food. The taste is kind of like herbal taste and a little huge. Im taking other suppliments too.. so when i take in the morning.. i couldnt tell the difference but i noticed whenever i take this before sleep my sleep has been so good.. when i wake up.. i feel like i had deep sleep and feel refreshed. Will be repurchasing this for sure.

Natural Support for Thyroid Health
Verified purchase
After trying MegaFood, Thyroid Strength, 90 Tablets, I can say it feels like a very balanced formula. I like that it combines whole food nutrients and herbs such as ashwagandha and schisandra, which makes it feel more complete than a basic supplement. The tablets are a bit larger, but easy enough to take with water. Overall, it gives steady support for energy, metabolism, and general well-being. I’ll continue to keep it in my routine.

It actually works!
Verified purchase
I've tried many supplements in the past to help with regulating stress, and this is the only one I've tried so far that works. When I start to feel flustered, I take the two-pill dosage and start to feel calmer within an hour. This is a high-quality product with great ingredients, and I hope MegaFood never stops making it!

Favorite daily multivitamin
Verified purchase
I've used this vitamin during intense periods of work with little sleep and high stress and have dodged colds that others around me were dropping like flies with. I feel solid and well supported with this, and will happily pay a bit more for such high quaintly. Love that its in a glass bottle, too!

Thyroid Strength
Verified purchase
I had borderline thyroid problems but not enough to go on medications. I started taking this and in less than 5 months I went back to the Dr. and new test showed normal readings. Before the readings were all off. This is a great supplement. I only will take Mega Food supplements.
