Are sugar substitutes really safe for your hormones? 🍭

One common concern is the research suggesting stevia might act as an oral contraceptive. I too was concerned when I first heard this years ago — but here’s what the research actually shows: the fertility effects were only seen with high-dose stevia extracts teas, at levels 10-60x higher than what’s normally used in food. And this has only been shown in animals.

The same goes for many other sweeteners — in typical amounts, they’re not likely to impact fertility or hormones.

That said, there are other factors to consider, like how sweeteners may affect dopamine reward pathways, which can influence cravings and eating behavior.

We break down all the research on commonly used sweeteners and answer your top questions!

How to build a Functional Thyroid Meal at the salad bar 🥗

✨I teach you all the functional foods and pairings of them to support thyroid function inside my program; Functional Thyroid Foundations. Plus you’ll get tons of meal ideas just like this that can be implemented wherever, whenever! Comment “FTF” and I’ll send you a link to learn more 🤎

🥬 leafy greens- antioxidants to protect thyroid cells from oxidative stress
🍗 protein- key for metabolism and hunger hormones but also tyrosine, an amino acid needed for making thyroid hormones
🧅 onions- rich in sulfur for making glutathione our body’s most abundant antioxidant
🥦 broccoli sprouts- packed in sulfurophane for liver detoxification, where t4 to t3 conversion happens
🥕 raw carrots- contain carotene that support bile flow that aids in t3 production
🫜 beets- contain nitrate that helps with thyroid hormone delivery throughout the body to target areas like the ovaries, hair, gut, etc!
🎃 pumpkin seeds- rich in zinc, a mineral needed for active thyroid hormone production
💩 prebiotics to support enzymes in the gut that convert thyroid hormones to their active form, t3

Top it with your own olive oil and acv for extra antioxidants and digestive juice support!

Until you’ve lived it you just don’t get it!!

10 years ago I wondered why me, but today I know that all these challenges were writing the story of how I could help and better understand you.

What people often don’t see is the years of fatigue, acne, 4+ years no menstrual cycle, unexplainable 20 lb. weight gain, gallstones, ovarian cyst ruptures, chronic digestive issues, and on paper doing everything right while my body was screaming at me that something was off.

I share this because I know so many women are living in that same in-between:
💤 exhausted but pushing through
🥗 doing “all the right things” but still feeling worse
🩺 searching for answers that never seem to come

If that’s you, please know — you’re not alone, and you’re not crazy. There are answers. And there is a way back to your health.

If this feels like your story too, drop a ❤️ below so you know you’re not alone.
