Check price on Amazon →pH-D vs Love Wellness: The Reference Boric Acid Against the Loudest One
Same printed 600 mg, same warnings, different boxes and very different prices. pH-D Feminine Health 36 count at $26.97 is about $0.75 per suppository; Love Wellness The Killer 14 count at $17.68 is about $1.26. Boric acid is not FDA-approved to treat any condition; both labels describe it for vaginal odor and pH support, and every box warning is stated before the verdict. Prices verified via the Amazon Creators API on September 5, 2026.

Before the verdict, the box. Boric acid vaginal suppositories are not FDA-approved to treat any condition. They do not treat, cure or prevent bacterial vaginosis or yeast infections, and neither pH-D's label nor Love Wellness's says they do; both describe the product for vaginal odor and pH balance support. Every box carries the same block of warnings: for vaginal use only; never take by mouth, boric acid is poisonous if swallowed; keep out of reach of children; do not use if pregnant or nursing; do not use on broken or irritated skin; see a clinician for a diagnosis before self-treating symptoms; and stop and see a clinician if symptoms persist or get worse.
With that said, the verdict: buy pH-D Feminine Health Boric Acid Suppositories, 600 mg, 36 count, at $26.97 (verified via the Amazon Creators API on September 5, 2026), about $0.75 per suppository ($26.97 divided by 36). Buy Love Wellness The Killer, 600 mg, 14 count, at $17.68, about $1.26 each ($17.68 divided by 14), only if a 14 count first box is worth 50 cents more per piece to you. The two products print the same strength, carry the same warnings, and differ in box size, price, packaging consistency and how much the brand promises on the front of the box.
This shelf is chemically uniform: 600 mg of boric acid in a capsule is what both titles state. So the comparison is about what differs, which is printed facts, per-piece price, owner consistency on firmness and packaging, and marketing tone.

The short version
- Read the box first: vaginal use only, never by mouth (poison if swallowed), keep from children, not in pregnancy or nursing, not on broken skin, see a clinician for diagnosis and if symptoms persist. Not FDA-approved to treat any condition.
- Both print 600 mg. pH-D 36 count at $26.97 is about $0.75 each; Love Wellness The Killer 14 count at $17.68 is about $1.26 each; The Killer 28 count at $34.99 is about $1.25, so the bigger Love Wellness box saves almost nothing.
- pH-D has the more consistent owner history on capsule firmness and the wider product line (72 count, moisturizing version, applicators, wash).
- Love Wellness has the smaller first box and the louder name; the label itself stays inside odor and pH language, and so does this page.
- If neither: AZO 600 mg 30 count at $19.49 is about $0.65 each from a pharmacy brand.

pH-D Feminine Health Boric Acid Suppositories for Women, 600 mg, 36 Count
pH-D Feminine Health
Printed 600 mg, 36 count, about $0.75 each, the shelf's most consistent owner history.
Our verdict: pH-D wins this comparison on the things that can be measured: 50 cents less per suppository, a longer and more uniform owner history on capsule firmness, and a product line that includes a 72 count, a moisturizing version and the brand's own applicators. It prints the same 600 mg as The Killer and its label stays in the same odor-and-pH lane. Vaginal use only; never by mouth; not in pregnancy or nursing.
Verified: 600 mg boric acid per suppository, 36 count, labeled for vaginal odor and pH balance support. Live at $26.97 on Amazon, verified via the Creators API on September 5, 2026.
The warnings, first. pH-D Boric Acid Suppositories, 36 count are for vaginal use only. Never take them by mouth; boric acid is poisonous if swallowed. Keep out of reach of children. Do not use if pregnant or nursing. Do not use on broken or irritated skin. Not FDA-approved to treat any condition. See a clinician for diagnosis, and stop and see a clinician if symptoms persist.
The line around it: the 72 count bundle at $41.99 is about $0.58 each once you know it suits you; the moisturizing 14 count at $16.99 is the brand's own small box, though its title does not print the milligrams; the applicators are $9.50. Full line notes in the pH-D boric acid review.
Who should buy it
Buy pH-D if you want the reference boric acid suppository at the lower per-piece price, have read every warning, and a clinician has already told you what is going on.
What we don't like
Thirty-six is a large first commitment, it costs more than AZO for the same printed strength, and the gelatin softens in a hot mailbox like every product on this shelf.

Love Wellness The Killer, 600 mg Boric Acid Vaginal Suppositories, 14 Count
Love Wellness
Printed 600 mg in a 14 count box, about $1.26 each; a smaller commitment at a higher price.
Our verdict: The Killer's case is the box size: 14 printed-600 mg suppositories for a first purchase, where pH-D asks you to buy 36. That convenience costs about 50 cents per piece, and the 28 count barely improves it. The name promises more than any boric acid product can; the label itself stays inside odor and pH support, and this page holds it there.
Verified: 600 mg boric acid per suppository, 14 count, Love Wellness. Live at $17.68 on Amazon, verified via the Creators API on September 5, 2026.
Same warnings, louder name. Love Wellness The Killer is 600 mg boric acid, vaginal use only, never by mouth (poisonous if swallowed), kept from children, not for pregnancy or nursing, not for broken skin, and not FDA-approved to treat any condition. Whatever the name implies, the label's use statement is odor and pH balance, and that is all this page will say for it.
Where Love Wellness differs as a brand is the pairing: the Killer and Flora Power duo at $30.59 bundles the boric acid with the brand's Flora Power probiotic suppository, a dietary supplement with its own structure/function label. Owners describe using them in sequence; the two categories are compared in boric acid vs probiotic suppositories. The standalone write-up is the Love Wellness The Killer review.
Who should buy it
Buy The Killer if you want a 14 count first box of printed 600 mg boric acid from an established brand and per-piece price is not the deciding factor.
What we don't like
About $1.26 each, a 28 count that saves almost nothing, and a product name that implies a treatment outcome the label does not and cannot claim.

AZO Vaginal Boric Acid Suppositories for Women, 600 mg, 30 Count
AZO
The same printed 600 mg from a name every pharmacy stocks, 30 for $19.49, about $0.65 each.
Our verdict: If the answer to pH-D or Love Wellness is neither, AZO is the pharmacy-brand option that undercuts both: 600 mg printed, 30 count, about $0.65 each. It splits the box-size difference at 30, and its owner history is close to pH-D's with slightly more variation on firmness. Same warnings, same odor-and-pH label.
Verified: 600 mg boric acid per suppository, 30 count, AZO. Live at $19.49 on Amazon, verified via the Creators API on September 5, 2026.
Identical warnings. AZO Boric Acid Suppositories are vaginal use only, never taken by mouth (poisonous if swallowed), kept from children, not for pregnancy or nursing, not for broken skin, and not FDA-approved to treat any condition. AZO's label language is odor and pH balance, the same as both subjects.
Who should buy it
Buy AZO instead of either subject if you want printed 600 mg from a mainstream pharmacy brand at the lowest per-piece price among the big names.
What we don't like
Slightly more variable firmness reports than pH-D, and a 30 count first commitment.

What you'll need
The six things that go with a vaginal suppository: applicators, pH strips so you know what you are treating, a probiotic and a vitamin E option, a moisturizer, and a gentle wash. See a clinician for diagnosis. Prices are approximate at time of writing.
Strength: identical, and printed on both
Both listing titles state 600 mg of boric acid per suppository. That is the amount nearly every boric acid vaginal suppository on Amazon states, and it makes the two products chemically the same on paper. Neither brand claims a purity grade in its title that the other does not, and words like medical grade or pharmaceutical grade on any supplement label are marketing rather than regulatory status.
Label language: what each brand says it is for
pH-D's label and listing describe the product for vaginal odor; its original 72 count listing prints the words for vaginal odor use in the title. Love Wellness's label describes odor and pH balance support. Both stay inside the lane a supplement is allowed, and neither claims to treat anything on the label itself.
The difference is the front of the box. The Killer is a product name that implies an outcome no boric acid label claims and no clinician would promise from a supplement. pH-D's name is a chemistry pun. We rank the label, not the name, and both labels pass; but a buyer who chooses The Killer because of what its name implies is buying something the box does not deliver, and the label's own instruction, see a clinician for a diagnosis, applies with equal force to both.
Box size and cost per suppository
All prices verified via the Amazon Creators API on September 5, 2026; cost per suppository computed only where the title states the count.
| Box | Strength (per title) | Count | Per suppository | Price (9/5/26) |
|---|---|---|---|---|
| pH-D 72 ct bundle | Not in this title | 72 | About $0.58 | $41.99 |
| AZO 30 ct | 600 mg | 30 | About $0.65 | $19.49 |
| pH-D 36 ct | 600 mg | 36 | About $0.75 | $26.97 |
| pH-D Moisturizing 14 ct | Not in title | 14 | About $1.21 | $16.99 |
| Love Wellness The Killer 28 ct | 600 mg | 28 | About $1.25 | $34.99 |
| Love Wellness The Killer 14 ct | 600 mg | 14 | About $1.26 | $17.68 |
Two things the table shows. Love Wellness is the most expensive per piece at every size it sells, and its larger box does not fix that. And pH-D's only small box, the moisturizing 14 count, does not print the milligrams, so a buyer who insists on both a small box and a printed 600 mg ends up with The Killer, which is the one honest case for it.
Packaging, firmness and what owners report
Because the chemistry is the same, the useful owner intelligence is about everything else. Firmness on arrival: gelatin capsules soften in heat, and pH-D draws fewer soft-capsule complaints than Love Wellness across a much longer review history. A soft capsule can be firmed in the refrigerator before use; see what to do when a suppository melts. Discharge: identical. Every boric acid capsule dissolves into a watery discharge the next morning, and owners of both brands describe it the same way; insert at bedtime and wear a liner. Irritation: a minority of owners of both brands report burning, and the label's answer is the same everywhere, stop and see a clinician.
Applicators: neither box includes one. pH-D sells its own; Love Wellness does not in this catalog. Options are ranked in the best vaginal suppository applicators, and the mechanics for either brand are in how to use a vaginal suppository.
The product line around each suppository
pH-D built an ecosystem: the 24, 36 and 72 count boric acid boxes, a moisturizing boric acid version, a hyaluronic acid suppository for dryness, applicators, a boric acid foam wash, wipes and a rinse. Love Wellness built a routine: The Killer, the Flora Power probiotic suppository, the duo that bundles them, and Good Girl oral probiotics. Neither ecosystem changes what the boric acid suppository is or is for. The probiotic products are dietary supplements with structure/function labels, ranked in the best vaginal probiotic suppositories.
The verdict, by buyer
- Has read every warning, has a diagnosis, wants the reference product at the better price: pH-D 36 count.
- Same, but wants a 14 count first box with 600 mg printed: Love Wellness The Killer 14 count.
- Same, but per-piece price decides it: AZO 30 count, or the pH-D 72 count once you know pH-D suits you.
- Wants the boric acid plus a probiotic suppository in one order: the Love Wellness duo; the categories are compared in boric acid vs probiotic suppositories.
- Pregnant, nursing, has a child in the house who could reach a capsule, or has not seen a clinician: neither, until those change.

How we chose
Every box on this page went through the same checks. We confirmed each live Amazon listing and price through the Creators API on September 5, 2026, took strength and count from the listing title only, and computed cost per suppository only where the title states the count. We read each brand's label for the use statement and the warnings, and we weighed owner reports across both brands for the things that differ between near-identical boric acid products: firmness on arrival, leakage, irritation, packaging, and whether the box's marketing matches its label. We do not use these products ourselves and we claim no clinical outcomes. No brand paid for this comparison.
Compliance for this shelf. Boric acid vaginal suppositories are not FDA-approved to treat any condition. We describe them as their labels do, for vaginal odor and pH balance support, and we never say they treat, cure or prevent bacterial vaginosis, yeast infections or anything else. Every box warns: vaginal use only, never by mouth, poisonous if swallowed, keep away from children, do not use if pregnant or nursing, do not use on broken skin, see a clinician for diagnosis and if symptoms persist. The probiotic products mentioned are dietary supplements. These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.
Questions, answered
Is pH-D or Love Wellness better?
For most buyers, pH-D. Both print 600 mg and carry the same warnings; pH-D's 36 count is about $0.75 per suppository against about $1.26 for Love Wellness The Killer 14 count on September 5, 2026, and pH-D's owner history on capsule firmness is more consistent. The Killer's one advantage is a 14 count first box with 600 mg printed. Neither is FDA-approved to treat any condition.
Are pH-D and Love Wellness the same strength?
Yes. Both listing titles state 600 mg of boric acid per suppository, which is what nearly every boric acid vaginal suppository on Amazon states. The strength does not decide the comparison and does not make either product a treatment for anything.
Does Love Wellness The Killer treat BV or yeast infections?
No. Boric acid vaginal suppositories are not FDA-approved to treat any condition, and Love Wellness's label describes The Killer for vaginal odor and pH balance support, not as a treatment. The product name implies more than the label claims. See a clinician for a diagnosis before using any boric acid product, and stop and see a clinician if symptoms persist.
Can you take pH-D or Love Wellness boric acid by mouth?
Never. Both are for vaginal use only, and boric acid is poisonous if swallowed. The capsules look like ordinary supplements, which is why every label says to keep them out of reach of children. If one is swallowed, contact Poison Control immediately.
Can I use either while pregnant or breastfeeding?
No. Both labels say do not use if you are pregnant or nursing, and this site repeats that without exception. If you are pregnant or nursing and have symptoms, see your clinician.
Which is cheaper per suppository?
On September 5, 2026: pH-D 72 count bundle, about $0.58; AZO 30 count, about $0.65; pH-D 36 count, about $0.75; pH-D moisturizing 14 count, about $1.21; Love Wellness The Killer 28 count, about $1.25; The Killer 14 count, about $1.26. Love Wellness is the most expensive per piece at every size.
What is the Love Wellness Killer and Flora Power duo?
A bundle of The Killer boric acid suppositories with Flora Power, the brand's vaginal probiotic suppository, at $30.59 on September 5, 2026. Flora Power is a dietary supplement with a structure/function label. Owners describe using them in sequence; neither product treats any condition.
Why is there discharge after using either one?
The capsule dissolves overnight and the contents mix with normal moisture, producing a watery, sometimes gritty discharge the next morning that owners of every boric acid brand describe. Insert at bedtime and wear a liner. Discharge that is foul-smelling, discolored, bloody, or accompanied by fever or pelvic pain is a different matter, and the labels say to see a clinician.
