New Development in Lactamo Clinical Evidence
We are proud to share the results of a recently independent performed from April to July 2025 to Amsterdam University Medical Center (AUMC). Powered by the team of 12 breastfeeding counselors, and under the direction of Elly Krijnen Ursem IBCLC, RN This study looked at how Lactamo affects their body quickly on breast inflammation using the most studied indicator: sodium in breast milk.
During the experiment, sodium levels were measured immediately before and soon after single use of Lactamo, and all other changes that are stable. The aim was to quantify the effectiveness of Lactamo in a real-time, controlled, clinical setting.
Findings: after just one use of Lactamo (for about 5 minutes), the average test wrote:
-
a 24% reduction in sodium intake; and
-
a 38% reduction in pain.
These results are significant and unprecedented in this context.
Lead tests Elly Krijnen Ursem comments:
“Lactamo is an exciting way to improve breastfeeding. The results are clear, and what’s really exciting is that this is a simple and accessible method that women can use themselves.”
Why Sodium Is Important as a Inflammation Marker
The relationship between the amount of sodium in breast milk and inflammation is well established. A well-known research is Perrella et al. (2022) showed that the sodium and sodium-to-potassium (Na:K) ratios are reliable, quantitative indicators inflammation of the breast, including mastitis, blocked ducts, engorgement, and enlargement.
In their long-term study of women with preterm infants, Perrella and colleagues observed that sodium levels rise during mastitis and return to normal within. 48 hours eliminate symptoms – regardless of whether the disease was confirmed by culture. This classifies sodium analysis as a real time, purposeful tool in breast health screening (PubMed link).
How AUMC Trials Build on Lactamo’s Clinical Validation
Previous studies have confirmed Lactamo’s clinical safety, efficacy, and user acceptability. The AUMC test adds a new dimension to the abundant biomarker evidence to that foundation:
-
Controlled measurement: the same breast, before using Lactamo once or once
-
A big change: 24% reduction in sodium concentration
-
Meaning: Physiological measurements of how swelling occurs within minutes of use
By combining the proven and patient-reported data from previous studies, the evidence base for Lactamo is now expanding. both women’s experiences and measurable environmental changes.
Why This Matters to Health Professionals
For health care providers, this is important for three reasons:
-
Testimonials: backed by science and controlled clinical trials
-
Useful: a self-made, non-invasive tool that women can use at home or in the clinic, quickly and easily.
-
About: it can quickly reduce inflammation, which can prevent it from progressing to a more serious condition
This latest trial reinforces Lactamo’s role as a reliable and effective agent in preventing and treating complications during breastfeeding.
