Copper supplementation aids hypothyroidism
The study focused on understanding how dietary copper affects physiological issues tied to reduced levels of peptidylglycine alpha-amidating monooxygenase (PAM), especially regarding hypothyroidism.

We evaluated the impact of PAM deficiencies in mice and found that those with reduced PAM levels struggled with thyroid regulation and body temperature, particularly when they were hypothyroid due to dietary restrictions. Interestingly, while these mice showed normal hormone response to cold, they couldn't maintain their body temperature effectively as compared to their healthy counterparts in colder environments.

However, when we introduced additional dietary copper, these PAM-deficient mice were able to stabilize their body temperature just as effectively as the normal mice. It appeared that copper supplementation helped restore some of the physiological functions that were impaired by low PAM levels.

Overall, our findings indicate that low dietary copper might exacerbate the challenges faced by those with PAM deficiencies, suggesting that copper intake could be an important factor in managing related hypothyroidism symptoms.

Zinc's uncertain role in hypothyroidism
We conducted a study to investigate the effects of micronutrient supplementation, including zinc, on thyroid function and overall quality of life in patients with hypothyroidism. Our trial involved 104 participants who were receiving levothyroxine and vitamin D. They were randomly assigned to either a group that received a mix of essential nutrients or a placebo group over eight weeks.

We measured various health markers before and after this period, including thyroid hormone levels, cholesterol, insulin resistance, and blood pressure. Our findings suggested that the group receiving the micronutrient supplement experienced improvements in insulin resistance and overall quality of life. However, it’s important to note that the specific effects of zinc alone are somewhat difficult to isolate, as it was part of a combination of nutrients being tested.

Ultimately, while the study indicates potential benefits of micronutrient supplementation for thyroid function in hypothyroid patients, further trials are necessary to clearly define the role of zinc and other nutrients in this context.

Boosts immunity
I've taken zinc before, particularly in autumn and winter. This zinc from Now Foods, L-OptiZinc, is excellent quality and helps address my zinc deficiency. I take it in courses, with effects noticeable after about ten days. Zinc bolsters immunity and improves hair, and I also utilise it for my thyroid, as I have hypothyroidism. The taste is neutral, and I highly recommend it.

Good quality zinc
This isn't my first time taking zinc, as I prefer it in the autumn-winter season. This product from Now Foods, L-OptiZinc, is high quality and effectively addresses my zinc deficiency. I take it in courses, noticing effects in about ten days. Zinc strengthens the immune system and hair, and I also take it for my thyroid due to hypothyroidism. The taste is neutral, and I recommend purchasing it.
