As a supplement
Talk to your doctor or pharmacist.
Roll Call does not check drug interactions or assess personal safety.
A dried, powdered preparation made from the pituitary gland of cattle or other animals, sold as a "glandular" supplement.
Why it’s used
Taken by some under the traditional glandular-supplement idea that consuming an animal organ supports the function of the corresponding organ in the human body.
What the evidence says
There is no established mainstream clinical evidence that consuming animal pituitary tissue affects human pituitary or hormonal function. Digestion breaks down most hormones and proteins present before they could act intact.
