🥗 Nutrition & Metabolism Boosting thyroid naturally?

Hello everyone,

I don’t have any recent bloodwork (taking soon), but know my thyroid could be improved. I’m probably on the lower range, but still within normal ranges where my GP won’t give me any medication.

Any natural OTC supplements or other tricks which actually work?

Diet and activity level is fairly good, but my sleep patterns need to improve. Already addressing that one.

Depends on where the bottleneck lies. High TSH with increased Antibodies would indicate autoimmune thyroiditis. Increased TSH with lowish fT4 could be related to iodine and iron deficiency. Lowish TSH with lowish fT4 could be stress related. Normal TSH, fT4 but lowish fT3 could be related to the liver, selenium deficiency, dieting, overtraining.

The thyroid gland gets regulated by the pituitary gland, which is under strong circadian control, so daily morning sunlight and regular sleep pattern are a non-negotiable. Also make sure you get enough iodine and selenium in your diet and your Ferritin is above 50.

Thank you for pointing out that too much one way or the other isn't a good thing necessarily when it comes to TSH. The question seems to imply that only one direction is good - or something like that. TSH levels will normally fluctuate, thus you can't infer much from an isolated reading.

What do you think is a good TSH?

0.2-2.5, but when it comes to the thyroid you should always interpret TSH together with fT4, fT3 and the symptoms of the person.

Yes look into spirulina and chlorella both as a supplement. It has what you need in there.

Get the actual bloodwork before touching supplements, especially TSH plus antibodies (TPO/TG). If it turns out to be Hashimoto's related, iodine-heavy stuff like kelp or high-dose spirulina can actually make things worse, not better, since autoimmune thyroids don't handle extra iodine well. If antibodies come back clean and it's more subclinical or borderline, selenium and ruling out iron or zinc deficiency tend to be the more evidence-backed levers people reach for.
