I am 21 year old a petite woman with 36DD breast. Are there any pills or supplements for breast reduction that are FDA approved?

I'm afraid there is no such magic pill, lotion or potion. However, there is a technique that will reduce your breasts without loosing nipple sensitivity or the ability to breast feed. The Horndeski Method/The Bellesoma Method has also completely eliminated the vertical scar component where most patients have trouble healing from. The Horndeski Method/The Bellesoma Method transfers the weight of the breasts to your chest muscles to relieve pain caused by large breasts. This maneuver effectively eliminates the need to remove excess amount of breast tissue to relieve pain. Being a young woman, you can appreciate the benefits this technique offers. Attached is a sample of what you can expect. No implants were used. I hope this helps. 
Best wishes and kind regards, 

Thanks for the question. I recommend you to send your photos to us to give you the advices you need and want.Kind regards

Many thanks for your question. I am not aware of a pill or supplement to reduce breast size. Be reassured that breast reduction is a highly successful and reliable procedure with a very low complication rate in the right hands. I would advise meeting with a plastic surgeon experienced in breast reduction surgery for assessment. Talk through your concerns with them. The more you understand about the procedure and what is involved will help you make an informed decision. All the very best, Jonathan Adamthwaite

in a nutshell, no there aren't any pills or supplements that can reduce your breast size. If you've already lost weight then you most likely need to consider a breast reduction surgery. During a consultation your concerns regarding side effects can be discussed. Best of luck. 

hi! Thanks you sharing your concern with us, the final solution for breast size its surgery, there is many techniques to make that procedure, its ideal if you can send photos of you to give recommendations 

Best whises!! :)

As far as I know, there are no pills that can cause the breasts to shrink.  If you want a breast reduction you will need to have surgery.

For breast reduction, the only method is surgical if you have already lost weight. Liposuction would result in a limited reduction but may not produce an aesthetically acceptable breast, depending on skin laxity and other factors.

The short answer is "no". If you are concerned about the side effects of a traditional reduction find a BCPS who specializes in the Scarless approach using liposuction only.Hope this helps.

Unfortunately, a breast size that is "stubbornly" resistant to exercise and diet means only one thing--the culprit is the excess tissue, which can only be removed by breast reduction surgery and thus no amount of non-surgical treatments can give you relief.  However, a small subset of patients with enlarged breasts may qualify for liposuction as a way to reduce their breast size.  Instead of long incisions, it only uses a few round incisions to remove the excess fat.

Nonetheless, I surmise that liposuction can give no or very little improvement given your age, i.e., young women tend to have more breast tissue relative to the amount of breast fat. 

Good luck and best wishes.
