UNDER THE MICROSCOPE 

GleeFull vs. Happy Mammoth

When you compare the 2 biggest names in hormone support, the differences are hard to ignore. 

"I was a Hormone Harmony user for about a year and saw hardly any lasting results, plus a 6-month supply was around $300. Finally made the switch to Gleeful and I’m feeling great: 17lbs down, no more fatigue or that awful brain fog, and my husband says I’m more energetic.

 

As long as Gleefull doesn’t change their formula they will have a customer for life!"

Compare The Cost

Fact: Happy Mammoth’s Hormone Harmony starts at $69.99 for a one-time purchase that runs out in just 24 days.

 (3 capsule serving size per day)

GleeFull Over 30 Hormone Support starts as low as $29 per bottle.

Each bottle contains a 30-serving supply (only 2 capsules per day).

✅ That's more servings, fewer capsules, and a dramatically lower price per day. 

Happy Mammoth Hormone Harmony (single jar): $69.99 for 24 days = ~$2.92/day

GleeFull O30HS (1-bottle): $29.75 for 30 days = ~$0.99/day

Over 3x cheaper for a formula that's arguably more comprehensive. Over a year, you're looking at hundreds of dollars back in your pocket.

The BEST Money-Back Guarantee in Hormone Supplement History

Happy Mammoth offers a 60-day money-back guarantee. That sounds decent, until you compare it to Gleefull's industry-leading 180-day guarantee.

Why does this matter? 
Hormone supplements take time to work. Some women feel a difference within days; others need 6–8 weeks for their body to fully respond. A 60-day window can feel rushed, especially if you're waiting on shipping, adjusting to the product, or simply need more time to evaluate results.

With Gleefull's 180-day guarantee, you have a full 6 months to decide if it's right for you. No pressure, no rush. That kind of confidence in a product says a lot about the brand standing behind it.

Will Your Body Absorb It?

Gleefull Over 30 Hormone Support, one of the most trusted herbal menopause supplements available, includes a patented black pepper extract called BioPerine®.

It has been clinically shown to dramatically enhance the absorption of nutrients and botanical ingredients.

💡Without it, most of the formula in the capsules pass through your system without being fully absorbed.
Happy Mammoth’s Hormone Harmony contains no absorption enhancer. 

Always Check The Label

When you look at Happy Mammoth's supplement facts label, you'll find just one standalone vitamin: Vitamin B6 at 100% DV. That's it.
Gleeful's formula includes a complete B-vitamin complex: Vitamin A, Thiamine (B1), Niacin (B3), B6, B12, and Pantothenic Acid (B5)... 
PLUS standalone L-Tyrosine and L-Arginine on top of the herbal blend.
Critical For Perimenopause Symptoms & Menopause Support ⤵️

B12 (at 2250% DV) is critical for energy, nerve function, and combating the fatigue that menopause can bring

B6 supports hormone metabolism and mood — Gleeful includes 3.8mg vs Happy Mammoth's 1.70mg

L-Tyrosine supports adrenal function and helps your body regulate stress hormones naturally

L-Arginine supports circulation and cardiovascular health, something that becomes increasingly important during menopause

Happy Mammoth's formula relies entirely on its herbal complexes.

Gleeful goes further, layering in amino acids and essential vitamins to support your body from multiple angles.

For women dealing with hormonal weight gain, cortisol belly fat, or stubborn perimenopause symptoms, the full-spectrum approach makes a difference.

Born From Personal Experience, Not A Boardroom

Gleeful was founded by Debbie and Marissa, two women who experienced menopausal symptoms firsthand and decided enough was enough.
Happy Mammoth was founded by Matt Murphy, a self-described "biohacker" and CEO. The product is formulated by a nutritional scientist and reviewed by a clinical advisory board, but the origin story isn't rooted in lived female experience.
When you're dealing with something as personal as hormonal changes, knowing that the people behind the product have walked in your shoes makes a difference.

153,223+ Women Made The Switch

Don't just take our word for it. Here's what women who made the switch are saying:

"After trying so many products that promised results, the Gleeful Over 30 Hormone Support is the only product that worked for me! After gaining 30 pounds during menopause and experiencing hot flashes that were so unbearable, this product worked miracles!! I am a life-long return customer." 

— Valerie P., Verified Buyer

"I was skeptical about taking a herbal menopause supplement as I was on HRT but it didn't seem to be working after 2 years. I tried this and within days my brain fog cleared and my belly got smaller. After about 6 weeks I started to feel so well and just stopped the HRT. I LOVE this, I cannot be without it now."

— Tiffany A., Verified Buyer

"I've been on these menopause support supplements for almost 4 months. They literally are giving me myself back! Mood swings, irritability, brain fog, trouble sleeping, exhaustion, bloating, weight gain, everything has improved so much in such a short period of time!" 

— Melanie P., Verified Buyer

The Winner Is Clear.

Happy Mammoth Hormone Harmony is a well-known product with a loyal following. 
But when you compare the formulas head to head, Gleeful Over 30 Hormone Support offers more: more servings per container, more nutrients, better absorption, a longer guarantee, and a significantly lower price… all from a brand built by women, for women.
Searching for the best menopause supplement?

If you've tried Hormone Harmony and want more for your money (or if you're starting your hormone support journey and want to get it right the first time) Gleeful is worth trying. With a 180-day guarantee, you've got nothing to lose.
