Best Spearmint Supplements on Amazon
I understand the appeal of spearmint capsules: they’re easier to carry than a mug and don’t require brewing. But the evidence that draws many people to this category used tea.
Quick Summary
If you’re happy drinking spearmint tea, you may not need capsules at all. If you’re pregnant, I’d skip these supplements; breastfeeding also needs clinician guidance. And if you want rapid, dependable changes in acne or unwanted hair, these products don’t have the evidence to support that expectation.
Swanson is the simplest documented one-capsule option if gelatin is acceptable. Nutricost offers a clearly described two-capsule leaf serving. HERBAMAMA is the vegan-shell pick, with a serving-size detail to double-check. I’d consider tea before all three because it’s closer to the preparation actually studied and may cost less.

How We Compared
We did not test these products. I compared the supplied records for form and dose relevance to studies, honest labels, third-party testing information, and price transparency. A testing claim isn’t a reviewed batch result. I haven’t verified live prices or every Amazon variant; check the selected label and cost per daily serving. Unresolved doses stay unresolved here.
The small randomized trial used spearmint tea twice daily for 30 days in women with PCOS (PMID: 19585478). Hormone changes did not translate into a significant objective hair-score improvement over that short period. I take that as a reason to keep expectations narrow, not as evidence that a higher-dose capsule would do better.
Swanson Full Spectrum Spearmint Leaf 400 mg
Why it fits: I like Swanson’s clear whole-leaf identity and simple one-capsule direction. Its official information specifies ingredients and a pregnancy warning, but convenience isn’t proof of a tea-equivalent dose.
The direction is one 400 mg capsule daily. The shell is gelatin despite inconsistent retailer metadata. Rice flour, silica, and magnesium stearate are also listed.
Limitations: The short tea trial didn’t show significant objective hair-score improvement. I can’t convert this capsule’s leaf weight into a validated brewed-tea dose.
Cons: Uses a gelatin capsule, so it is not vegetarian despite some retailer metadata inconsistencies. Contains rice flour, silica, and magnesium stearate.
Who it’s for: Someone who wants a simple one-capsule routine, accepts gelatin, and understands the tea-to-capsule evidence gap. Who should skip it: Vegetarians, pregnant readers, and anyone expecting a predictable change in hair growth within a month.
When something else is better: HERBAMAMA suits a vegan-shell preference. Tea may be cheaper if you enjoy it, though I wouldn’t call the two formats dose-equivalent.
Worth comparing: HerbsPro’s Swanson Full Spectrum Spearmint listing.Nutricost Spearmint Leaf 1000 mg Capsules
Why it fits: Nutricost’s supplied retailer label documents 120 capsules and 60 servings. I appreciate that clear arithmetic for comparing daily cost rather than a large front-label number.
Two capsules provide 1000 mg whole-leaf powder. It isn’t standardized to a marker compound; the larger leaf weight doesn’t establish a stronger effect than a 400 mg capsule.
Limitations: There’s no validated capsule-to-tea conversion. If PCOS or acne prompted the search, this shouldn’t displace medical evaluation or an established care plan.
Cons: Requires two capsules per labeled serving. The product is whole-leaf powder rather than an extract standardized to a marker compound.
Who it’s for: A reader who values a documented 60-serving bottle and doesn’t mind two capsules per serving. Who should skip it: Anyone seeking a standardized extract, avoiding a two-capsule routine, or assuming a larger leaf weight means stronger clinical evidence.
When something else is better: Swanson needs only one capsule if gelatin is acceptable; HERBAMAMA documents a vegan shell. I’d compare tea costs before paying for more printed milligrams.

HERBAMAMA Spearmint Capsules 1000 mg
Why it fits: HERBAMAMA makes my shortlist for its vegan pullulan shell. The supplied sources identify a 100-capsule bottle and 1000 mg serving; the shell doesn’t establish clinical benefit.
The serving supplies 1000 mg leaf. The supplied brand direction is two capsules, giving 50 servings per 100-capsule bottle, but confirm that line on the selected Amazon label.
Limitations: The evidence used tea, and hormone changes don’t establish reliable acne or hair improvement from this capsule. Breastfeeding safety remains insufficiently established.
Cons: The serving-size detail is less transparent in indexed product text and needs label verification. The brand page emphasizes broad digestive, respiratory, and skin marketing beyond the narrow small-trial evidence.
Who it’s for: A reader who specifically wants a vegan capsule shell and will verify the current serving instructions. Who should skip it: Anyone who is pregnant, needs settled breastfeeding safety information, or wants the marketing claims to stand in for capsule-specific research.
When something else is better: Nutricost has clearer supplied serving arithmetic. Plain spearmint tea avoids shell questions and may be cheaper; wider marketing claims wouldn’t justify a premium to me.

FAQ
Did the tea study show less unwanted hair? The objective hair-score change wasn’t significant over 30 days, despite hormone changes in the small trial (PMID: 19585478). That difference matters.
Would drinking spearmint tea be enough? Tea is the preparation the cited trial actually used, twice daily. If you like drinking it, it may be the simpler, cheaper choice than a capsule.
Is a 1000 mg serving better than 400 mg? The supplied evidence doesn’t establish that. Both numbers describe leaf weight, and neither provides a validated match to the brewed preparation.
Who should leave these supplements alone? I’d skip them during pregnancy and seek clinician advice during breastfeeding. I also wouldn’t use them to postpone an assessment for new or changing symptoms.

Our Take
I’d try the tea format first if it suits your routine and a clinician has no concerns about your use. For capsules, Swanson wins on simplicity, Nutricost on clear serving arithmetic, and HERBAMAMA on its vegan shell.
