Anxiety, Fatigue, and Mood Issues ARE NOT Normal In Motherhood! w/ Nichole Krueger
Feeling exhausted, anxious, or like you’ve lost yourself in motherhood?
You’re not alone—and it’s not “just stress” or “part of being a mom.” Burnout, anxiety, and constant fatigue are often signs of deeper, correctable imbalances.
Through functional lab testing, we uncover the hidden root causes—like gut issues, hormone imbalances, nutrient deficiencies, or other stressors—that conventional approaches often miss. When you finally see the data, you realize you’re not crazy, you’re not failing, and it’s not all in your head. You just need the right roadmap.
That’s where the D.R.E.S.S. approach (diet, rest, exercise, stress reduction, supplementation) comes in. With small, sustainable changes that fit your busy life, you can restore your energy, balance your mood, and feel calm and confident again—without overhauling everything at once.
