font_0 Health Benefits

Thyro-T (formerly called Prosperi-T) provides a sense of well-being, while supporting normal thyroid gland activity. It provides precursors necessary for thyroid hormone production, which supports natural energy levels and calms stress and anxiety.

Common Supplement Results

Thyro-T needs to build up in the body over time in order for you to experience its full effect. After taking it for 60-90 days, people usually notice stabilization of their weight, better sleep, and a diminishment or cessation of hair loss.*

Everyone is different, and results will vary from person to person. The key is to maintain consistent use every day to see best results.*


Take two capsules every morning with or without food.


You can think of your thyroid as the ultimate regulator. It regulates your weight, energy, and mood - which are pretty important things to get right. If your thyroid hormone levels are either too low or too high, it can make every day life difficult.

That’s why we created Thyro-T to help you regulate the activity of your thyroid gland without the side effects of pharmaceuticals. We use natural ingredients that act as precursors your body needs in the production of thyroid hormones. They help your body get back in balance so it can do what it’s supposed to do naturally.

We use plants and amino acids like Ashwagandha, Coleus Forskohlii, L-Tyrosine, and Thyroid (bovine, hormone-free) that work together to support natural energy levels and leave you with a general sense of well-being. We even use kelp, which is a form of seaweed and is chock full of iodine your thyroid needs to function properly.

  • Coleus forskohlii 

    Coleus Forskohlii is traditionally used in Ayurveda, and promotes metabolic processes.*

    WHY WE INCLUDED IT: Coleus Forskohlii is known to activate cAMP (cyclic adenosine monophospate) which deals with cellular energy.  cAMP supports the biochemical messenger responsible for cellular processes including hormonal messenger activation.  Coleus Forskohlii is shown to support thyroid hormones, fat burning and fat storage.*

    WHY WE INCLUDED IT: Zinc is an essential mineral, and a daily intake of zinc is required to maintain a steady state, because the body has no specialized zinc storage system.

Thyro-T Supplement Reviews

Helped get off thyroid medication
I have been taking Thyro-T for about 2 months. I like the natural energy it seems to give me and gives me a sense of balance. I have a lot of customers in our store that take it and were able to get off of thyroid medication.

Super Clean Thyroid Support
I have Hashimoto's Thyroiditis and negative reactions to most of the thyroid prescriptions on the market. I've tried so many different thyroid support blends and I've come to rely on Prosperi-T. I love how clean the product is, I've never had a negative reaction, and best of all, I can actually feel it working for me. I would definitely suggest this product to anyone who has a thyroid condition and is looking for something clean.

great stuff
I ordered Mobili-T, and Thyro-T, the items came quickly, email communications were great, and I can feel the stuff actually working. I've been searching for a good source of iodine, which the Thyro-T has, and I felt better within 2 days of taking it. And Mobili-T must work as my joints dont twinge like they have done. Life Seasons are a great product that actually have what they say is in them. I also like the samples that were sent along with my first order.
