Bioma and Happy Mammoth sell different products for different goals, so this comes down to fit more than a winner. Bioma’s own product page lists its Feminine Health Synbiotic, described as “a women’s wellness formula,” at $104.97 every 3 months. Happy Mammoth sells a range of gut and hormone supplements, and its homepage lists Complete Belly Reset™ among them, so this comparison uses that product as the match.

What is in each one, and what is the dose?
Bioma
Bioma’s product text names probiotic strains, cranberry powder and tributyrin. The strain names and the amount of each per serving are on the Supplement Facts panel of the bottle, so read that panel before you compare.
Happy Mammoth
Check the Supplement Facts panel on the Complete Belly Reset label for each ingredient and its amount per serving. Happy Mammoth’s homepage says its formulas have “NO added artificial flavors, colors or preservatives, magnesium stearate, yeast, nuts, soy or sulfates.”
How much does each cost per bottle and per day?
Bioma’s page shows $104.97 every 3 months, as of October 20, 2026. To get a daily cost, divide that amount by the number of days a supply lasts, which the label’s serving count will tell you.
For Happy Mammoth, check the current price at its checkout. Happy Mammoth says it offers subscriptions at discounted prices. Prices and bundles change, so check today’s price directly with each seller at checkout.
What are the side effects, and who should ask a clinician first?
Happy Mammoth’s footer says: “Pregnant women: Please consult your doctor before using this product.” Its blog on its gut repair system says to “consult with a medical professional before starting any regimen if you are taking any medications or have underlying health conditions.”
The MedlinePlus hypothyroidism page describes Hashimoto’s disease as “an autoimmune disorder where your immune system attacks your thyroid.” The NIDDK hypothyroidism page says large amounts of iodine “may cause or worsen hypothyroidism,” that iodine supplements can have the same effect, and that you should talk with your health care team about iodine supplements if you take them.
If you take medicines, are pregnant, or have a health condition, ask a clinician before you start either product, and bring the label with you.
Is Bioma safe?
Bioma’s disclaimer says: “This product is not intended to diagnose, treat, cure, or prevent any disease.” It adds: “Please consult a qualified healthcare provider when making medical decisions.” Read the label, then check it with your clinician before you start.
Is Bioma FDA-approved?
Bioma’s disclaimer says its “Content and statements on this website have not been evaluated by the Food and Drug Administration.” Happy Mammoth’s footer says the statements on its website “have not been evaluated by the FDA.” Both are the sellers’ own statements about their websites.
How do refunds, guarantees and cancellations work?
Bioma’s return and cancellation terms
- You have 14 days from delivery to ask for a refund. A refund applies if the product is unopened and in its original packaging and fit for resale, or if it is not as described or faulty.
- For an unopened item, you email hello@bioma.health with your proof of purchase. Bioma then sends a prepaid shipping label, which costs 9 USD and is deducted from the final refund.
- For a faulty or not-as-described item, you email within the same 14 days with detailed information and visual proof of the fault. The prepaid label costs 9 USD.
- Bioma says refunds for unopened subscription products cover the initial purchase only, not recurring shipments.
- A refund goes to your original payment method within 10–30 business days of Bioma receiving and inspecting the return. It can take up to 14 more working days to reach your bank.
- To cancel a subscription, do it at least 48 hours before the current period ends. The terms say cancellation is only possible after the second subscription charge. Cancelling before that charge means paying the difference between the subscription price and the regular price.
- You can pause a subscription for 30 days, at least 48 hours before the period ends, through the self-service area of the site.
- If you bought through Amazon, Bioma says Amazon’s terms apply, and Bioma does not take responsibility for Amazon returns or refunds.
Happy Mammoth’s guarantee and subscription terms
- The homepage says you “can try our formulas risk-free to see how they work for you – thanks to our Satisfaction Guarantee.”
- The refund window and steps are on its Refund Policy page, which the footer links. Read that page before you order.
- Its terms say subscribers have “a three month minimum subscription period from the date of first purchase.”
- The homepage says it offers free shipping on orders over $99.
How do I contact Bioma Health customer service?
Email hello@bioma.health. Bioma’s terms use that address for cancellations, returns and changes to recurring shipments, so put your order number in the subject line. A change of shipping address for a recurring order must reach them at least 72 hours before the end of the current period.
Happy Mammoth’s footer lists support@happymammoth.co, a Support Page and a Manage My Subscription page. The footer also says not to send products to the mailing address it lists.
What do buyers see in reviews?
Happy Mammoth’s homepage, as of October 20, 2026, gives its own figures: 12899+ Trustpilot reviews, 406K+ Facebook reviews and 685K+ Instagram followers. Its banner says it is “Trusted by over 3.3 million happy customers.” These are the brand’s own counts, not a quality rating. One testimonial on the same page reads: “Health is wealth, so yes the great effects are worth the price.”
For Bioma, read buyer reviews on a review site you choose, and check the date on each one.
Is Bioma worth the money?
That depends on what you need the bottle to do and whether you can accept the subscription terms. At $104.97 every 3 months, the cancellation rule matters most. Cancelling before the second charge costs you the difference between the subscription and regular prices, so read that rule before you start. For Bioma’s refund and side-effect points in one place, see our bioma probiotics reviews page.
Price alone does not answer the value question. A stand-in measure, such as a bacteria count, is not the same as how you feel, a gap that surrogate endpoints explained (our research library) covers. Ask what each label promises and how you would know it is working for you.
Could I just make this myself?
Bioma’s paid press release lists yogurt, kefir, sauerkraut, tempeh and kimchi as probiotic foods. Doing it yourself means choosing those foods, eating them every day, and knowing what each one contains. Happy Mammoth’s blog makes the case for a done-for-you version: its gut repair system “eliminates the guesswork.” A product is the easier route if you want that structure. Food is the route if you prefer to build it yourself.
Which one fits your goal?
Bioma’s product text centres on gut, vaginal and urinary support and hormonal balance. Choose it if that is your goal and the feminine health focus fits you.
Happy Mammoth’s range covers other goals. Complete Belly Reset is the Happy Mammoth product compared above. Its homepage lists Hormone Harmony™ among its best sellers. Its homepage says it helps women “manage their weight in a healthy way,” and it lists Ultimate Weight Control™ as a product. For Hormone Harmony’s price and safety questions, read Happy Mammoth vs Hormone Harmony.
Bioma for weight loss, and whether it is a GLP-1 supplement
Bioma’s product text describes gut, vaginal, urinary and hormonal support. If an ad or seller calls a Bioma product a GLP-1 booster, check the product name on the label and at checkout. Then ask hello@bioma.health which ingredients it contains before you compare it with the probiotic.
Before you order
- Your goal: feminine and urinary support, digestive comfort, or hormones. That answer decides which product to compare.
- The strain names and the amount per serving, on each product’s Supplement Facts panel.
- Your daily cost: the price divided by the days the serving count covers.
- Today’s price for each product at checkout, since prices and bundles change.
- Happy Mammoth’s refund window on its Refund Policy page, and whether a three-month subscription minimum fits your plans.
- Whether you are pregnant, take medicines, or have a thyroid condition. Ask a clinician before you start either product.
- Where you buy. Bioma says it is not responsible for purchases made through Amazon.com, which fall under Amazon’s terms for returns and refunds.
If you have already paid
If you bought Bioma, email hello@bioma.health this week, within 14 days of delivery, with your receipt and, for a faulty item, visual proof of the problem. If you bought Happy Mammoth, open the Refund Policy page from its footer, then write to support@happymammoth.co with your order number.
