What the research says
In an 8-week randomised controlled trial, people with Hashimoto's thyroiditis who took 2 grams of Nigella sativa powder daily had lower TSH and anti-thyroid peroxidase (anti-TPO) antibodies, and higher T3, than placebo.[1]
Taking it with levothyroxine
Take thyroid medicine on an empty stomach as prescribed, and take supplements at least 4 hours later. Get thyroid levels checked if you start something new.
When to see a doctor
Black seed oil and oregano oil are not a substitute for diagnosis or prescribed treatment. See a healthcare professional if symptoms are severe, getting worse or not improving.
