- The importance of supporting gut health, preserving muscle mass through strength training, and addressing cortisol and s*x hormone imbalances alongside GLP-1 use
- Key considerations for women in perimenopause and menopause, including the role of hormone therapy when using GLP-1 receptor agonists

The body is always adapting to its environment. During periods of chronic stress, that adaptation often means prioritizing cortisol production to help us cope with perceived threats.

But when survival mode becomes the norm, the hormonal systems that support reproductive health and resilience may be downregulated. Through comprehensive hormone and cortisol testing, the DUTCH Test helps illuminate how stress may be influencing a patient’s symptoms and overall hormone health.

Summer is the perfect time to let nature inspire what’s on your plate. ☀️🍓🥒

Eating seasonally isn’t just a delicious way to enjoy produce at its peak, it can also support hormone health. Seasonal fruits and vegetables provide fiber, antioxidants, vitamins, and minerals that help support healthy digestion, blood sugar balance, and hormone metabolism.

From hydrating cucumbers and watermelon to antioxidant-rich berries and peaches, summer produce can help nourish your body while adding color, flavor, and variety to your meals.

Bonus: choosing seasonal foods often means fresher produce, fewer food miles, and more support for local farmers. 🌱

What’s the first summer fruit or vegetable you reach for this time of year? 🍑🍉🍅👇

Join us for our monthly webinar on Wednesday, June 17th, from 12-1pm PT!

Dr. Kaitlyn Tyre, ND will be speaking about Premenstrual Dysphoric Disorder (PMDD). PMDD is a severe, cyclical disorder affecting females of reproductive age that is often misunderstood, underdiagnosed, and challenging to treat.

Although it is well understood that cycling s*x hormones play a role, emerging evidence suggests that PMDD is not simply a disorder of s*x hormone levels, but rather a condition of heightened sensitivity to normal hormonal fluctuations.

This session is designed to equip clinicians with a deeper understanding of PMDD and provide them with practical tools to better support patients experiencing this debilitating disorder.

Adding supplements to your routine could make you feel better for a few weeks, but lifestyle changes will make you feel better for life.

A strong foundation of sleep, nutrition, movement, and stress management will set you up for success in your health journey. The DUTCH Test is here to help you uncover the hormonal reason why you’re not optimizing in each of these areas. We always say, “test, don’t guess,” because we want you to feel certain about the choices you’re making for your health.

“Nothing has changed, but I’m gaining weight anyway.”

It’s one of the most common frustrations women experience during perimenopause.

The reality? A lot has changed.

Fluctuating estrogen and progesterone levels can influence insulin sensitivity, fat distribution, muscle mass, appetite signals, sleep, and stress resilience. As a result, familiar nutrition and exercise strategies may not deliver the same results they once did.

This is one reason GLP-1 medications have gained so much attention in recent years. But are they the right solution for perimenopausal weight gain?

Our latest blog takes a closer look at the science behind GLP-1s, their potential benefits and limitations, and why addressing metabolic symptoms is only one piece of supporting women through the perimenopausal transition.

Because perimenopause isn’t just about weight, it’s about long-term health, resilience, and understanding what your body needs during a time of significant change.
