After weeks of feeling “off” with my mood was all over the place and my energy was always depleted by 2 p.m., I started digging into natural ways to support my hormones. That’s when I came across Hormone Harmony by Happy Mammoth.
It promised to help with hormone imbalances, PMS, mood swings, fatigue, weight issues, and even sleep. I was skeptical. But curiosity (and desperation) won. I bought a bottle and here’s how it actually went.

What Is Hormone Harmony?
Hormone Harmony is a plant-based supplement created by Happy Mammoth. It’s designed to support women’s hormone balance, particularly during PMS, perimenopause, and stress-related imbalances.
The formula includes:
- DIM (Diindolylmethane) – Helps with estrogen balance
- Maca root – Supports energy, libido, and mood
- Chasteberry (Vitex) – Used for PMS and cycle regulation
- Ashwagandha – Adaptogen that helps with stress
- Rhodiola rosea – May support mood and mental clarity
They claim the supplement supports natural detox pathways, eases hormonal symptoms, and helps you feel more “balanced.”
Is Hormone Harmony FDA Approved?
No, Hormone Harmony is not FDA-approved but that could be because dietary supplements aren’t required to be approved by the FDA. However, Happy Mammoth states that the product is made in FDA-registered facilities following Good Manufacturing Practices (GMP), which is the standard for supplement production.
Is Happy Mammoth Hormone Harmony Safe?
For most healthy adults, the ingredients in Hormone Harmony are generally safe and widely used in herbal medicine. I didn’t experience any negative side effects while taking it.
However, if you are pregnant, nursing, on medication (especially for hormones, mood, or thyroid), or have existing health conditions, please consult your doctor before using it.
My Experience: Does Hormone Harmony Actually Work?
I didn’t go into this expecting a miracle as I just wanted some relief from the hormonal chaos I had been feeling. The first week, I didn’t notice any major changes, but that didn’t surprise me. Most natural supplements take time to build up in your system. I kept taking two capsules a day with food, like the label suggested, and paid attention to how my body responded.
By the second week, I started noticing some subtle shifts. My energy felt a little more stable throughout the day. I wasn’t hitting that usual 3 p.m. wall where I normally reached for caffeine or just feel completely wiped out. My sleep also started to improve, not in a dramatic way, but I was falling asleep faster and waking up less during the night. That alone made my days feel more manageable.
By week three, I realized I hadn’t been as bloated, especially around my period. Normally, I feel uncomfortable in my clothes for days leading up to it, but this time the bloating was noticeably less intense. Emotionally, I also felt more balanced. The mood swings I usually get before my cycle were still there, but they weren’t as sharp or unpredictable. It felt like my emotions had a little more “buffer,” if that makes sense.
By the end of week four, I was genuinely impressed. My PMS symptoms were still present, but far more manageable. The biggest difference was in how I felt day-to-day and I was more like myself. I wasn’t constantly overwhelmed or on edge, and I didn’t feel like I was fighting against my own body.

Conclusion: Would I Recommend Hormone Harmony?
Yes, but with realistic expectations. If your hormones feel off and you’re looking for a natural, non-invasive way to support your system, Hormone Harmony is worth trying. It’s not a cure-all, and it doesn’t work overnight, but I genuinely felt better on it. The biggest improvements for me were energy, mood, and pre-period symptoms.
