After working with Truly Well Nutrition

Better results start with root-cause answers

“After going through the program, I have ZERO GI issues, I can eat foods that used to hurt my stomach, I have such a healthier relationship with food and myself, and I HAVE A PERIOD for the first time in 10 years.” 

Period back after 10 years. Zero GI issues. Bloating gone.

“Tracy is an incredible teacher. Since working together, my thyroid function has improved, my blood sugar feels more stable, I’ve been sleeping better, my energy is up, I have way fewer cravings, and my skin is clear.” 

Thyroid improving. Energy back up. Sleeping better. Fewer cravings.

“My psoriasis has almost completely cleared, my previously irregular cycles come every month like clockwork, my skin is brighter and calmer, and my anxiety feels so much more manageable. I feel balanced, energized, and confident again.” 

Psoriasis 95% gone. Regular cycles. Anxiety dialed way down.

- ali

“After working with Tracy, I finally trust my body again. I go to the bathroom regularly without any laxatives, am able to eat out without discomfort and stress, rarely ever experience bloating, and have finally seen how much better my body functions when I eat more.” 

Off laxatives. Off acne medication. Eating the foods she cut out.

As a Functional Dietitian Nutritionist and founder of Truly Well Nutrition,
I help women find and address the root causes of their hormone, gut, skin, and cycle symptoms.

Hey, I’m Tracy Greenstein, MS, RD

get the full story

But before I was a practitioner, I was the classic “girl with tummy issues.” Always bloated. Exhausted no matter how much I slept. Missing my period for three years. Dealing with inflamed, angry skin, and trying to figure out why my body felt so off even though I was doing everything “right.” 

So I turned to doctors. Yes, plural. And I found that most conventional treatment options were focused on managing my symptoms, not understanding why they were happening in the first place. Eventually, I found a practitioner who slowed down, listened, and looked at what my labs were actually saying. For the first time, my body began to heal. Because we didn’t address symptoms, we addressed the cause.
I built Truly Well Nutrition because women deserve a higher standard of care the first time. Not after years of being dismissed, not after trying everything on their own, not after settling for "your labs are normal" as an answer. The first time. That’s my standard. 

And it works. I’ve watched women get their periods back after a decade, clear psoriasis their dermatologist couldn’t touch, and eat foods they’d spent years avoiding. If you’re ready to get your body back on your side, you’re in the right place.
