Clinical support for Asparagus racemosus (shatavari) is rapidly expanding. Building on a positive 2022 clinical trial shared earlier on my page, a newly published RCT by a separate research team has also found that shatavari significantly enhances breast-milk production in lactating women.
A total of 120 women who had recently given birth took part in the study. Half of them took 300 mg/day of a shatavari root extract (10% shatavarins, extract ratio not specified), while the other half were given a placebo, and the results were measured after 72 hours. Researchers observed statistically significant positive changes (compared to placebo, per-protocol) in milk supply volume, the time it took for the mothers to feel their breasts were full, and how satisfied the mothers felt with breastfeeding.
Effect sizes were good. At 72 hours, shatavari supplementation produced no difference in the timing of milk expression compared with placebo (p = 0.961), indicating that the intervention did not alter feeding or expression behaviour. In contrast, milk volume expressed at 72 hours was significantly higher in the shatavari group (97.98 ± 14.34 mL) compared with placebo (85.36 ± 14.19 mL), with a mean between-group difference of 12.63 mL. This corresponds to a large effect size (Cohenâs d = 0.889; p = 0.001), indicating a substantial and clinically meaningful increase in milk production.
Additionally, shatavari was associated with a significant reduction in time to evident breast fullness after the last feeding, with mothers reporting earlier fullness compared with placebo (mean difference â0.56 h). The effect size was moderate (Cohenâs d = â0.504; p = 0.002), suggesting improved mammary refilling dynamics.
Importantly, no side effects were observed in any of the mothers who took Shatavari root extract. These results suggest that immediate post-partum use of Shatavari root extract is a safe and effective natural option to increase breast milk volume.
