Thoughts on Quercetin supplements

[Corkie1958]

Hi All

Ive just joined the group and was wondering if anyone out there is taking Quercetin and have had any results good or bad with interaction with thyroxine...

I have been recommended it post Covid infection for its anti-inflammatory effects and its effects on histamine... I have been getting terrible allergy responses recently and am not getting on with traditional antihistamines...

Would appreciate your thoughts

If you type 'quercetin and thyroid' into google several studies come up which state that it can inhibit thyroid function. You would need to look at the summaries and decide for yourself.

You might find this helpful, ...unfortunately the rest of the paper is behind a pay wall.

I was chatting to someone recently who was concerned that quercetin was having a negative effect on their thyroid function. The above link came to light.

I imagine the size of dose is significant

Sorry that's as much as I know, others may pop in and help further.

Take care

Thanks for you reply DD and la la T

I’m thinking that’s maybe the key, dosage... I know of people who take this in large doses circa 2400mg which could negatively impact kidney function let alone Thyroid however they are taking it to see if it will help inflammation post Covid ... I’m considering a small dose of 250mg per day to see how I feel then up to suggested dose of 500mg, this particular brand has Vit C added too...
