El producto está bien, pero en mi caso no noté ninguna diferencia al usarlo.Puede que funcione para otras personas, pero para mí no cumplió con lo que esperaba.No es malo, pero no…
El producto me llegó con retraso, cuando abrí la caja sinceramente era más pequeña de lo que esperaba, pero cuando la probé realmente es buena , lava muy bien y deja la ropa casi seca,la manguera para llenar tiene la boquilla muy pequeña y no le sirve a mi grifo tuve que llenarlo en la bañera, recomiendo este producto es muy funcional y como es pequeña cabe en cualquier espacio. · April 2026

Feminiva Boric Acid 600 mg -30 vaginal suppositories. USP-grade boric acid for restoring and maintaining the acidic vaginal pH (3.8-4.5) that supports a balanced intimate environment and ongoing vaginal comfort.
Why It Works
The Evidence Behind Boric Acid for Vaginal pH Balance
Restores the Correct Vaginal pH
A healthy vagina maintains a pH between 3.8 and 4.5 -acidic enough to inhibit the overgrowth of BV-associated bacteria (Gardnerella, Prevotella) and Candida species. Boric acid is weakly acidic and fungistatic; it works by acidifying the vaginal environment and disrupting biofilm formation.
Clinical Evidence for Vaginal pH Maintenance
A 2011 systematic review by Iavazzo et al. (Archives of Gynecology and Obstetrics) analyzed published clinical data and found boric acid to be a safe and well-supported option for maintaining vaginal pH balance, particularly after standard antibiotic use. Women in boric acid maintenance groups experienced meaningfully more stable vaginal pH over the follow-up period.
pH Support Even in Challenging Cases
Boric acid supports vaginal pH balance even in challenging cases involving Candida glabrata -a species less responsive to standard over-the-counter antifungal azoles (clotrimazole, miconazole). Its distinct acidifying mechanism offers an additional option when standard approaches have fallen short.
Disrupts Vaginal Biofilm
Vaginal imbalances can involve biofilms -structured communities of bacteria or fungi that are significantly harder to address than free-floating organisms. Boric acid has demonstrated the ability to penetrate and disrupt these biofilms, which is one mechanism behind its effectiveness when standard approaches fall short.
Not an Antibiotic -Does Not Disrupt Lactobacilli
Standard antibiotic regimens kill pathogens but can also reduce beneficial Lactobacillus populations, which can predispose to imbalance recurrence. Boric acid lowers pH without broadly targeting bacteria -supporting an environment where Lactobacillus can reestablish naturally.
USP-Grade Purity, Made in USA
Feminiva uses United States Pharmacopeia (USP) grade boric acid -the same pharmaceutical standard used in clinical compounding. Manufactured in an FDA-registered, GMP-certified facility with no artificial colors, dyes, or unnecessary excipients.
Vaginal pH Maintenance Support
Boric Acid as a Maintenance Protocol Following Initial Antibiotic Use
The Iavazzo 2011 systematic review and subsequent clinical studies support boric acid as a maintenance protocol following initial antibiotic use for vaginal pH restoration. Women who used boric acid suppositories twice weekly after completing antibiotics had significantly lower recurrence rates than those who used antibiotics alone. Boric acid works best as part of an ongoing maintenance protocol -consistent use is key to supporting stable vaginal pH over time.

What to Expect Over 3 Months
Foundation
Month 1
For acute recurrence: a 7-day course of one suppository per night typically restores normal vaginal pH and reduces symptoms (discharge, odor, irritation) within 3-7 days. If symptoms do not improve within 7 days, consult your gynecologist -a diagnosis confirmation is important before repeating use.
Important safety information: Feminiva suppositories are for vaginal use only. Do not take orally -boric acid is toxic if ingested. Not for use during pregnancy. Keep out of reach of children.
