Bovine colostrum supplementation in rugby.
Trial report in European journal of applied physiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionBovine colostrum is a nutrient-dense first milk, rich in bioactive compounds such as immunoglobulins and growth factors, which may enhance athletic performance and immune function. Rugby union involves high-intensity training for both aerobic and muscular power, which could leave athletes vulnerable to opportunistic infections. PURPOSE: This double-blind, randomized study examined the effects of 8 weeks of bovine colostrum supplementation (38 g/day) versus soy protein in 29 club-level rugby players (three women) during the competitive season.
methodsMuscular strength (1RM bench and leg press) and power (vertical jump), aerobic power (20 m shuttle run), body composition (DXA and ultrasound), and salivary immune and inflammatory markers (IgA, CRP, IL-6, IL-1β) were assessed at baseline and after 8 weeks of supplementation.
resultsBovine colostrum supplementation significantly improved vertical jump height (+ 1.0 cm in the colostrum group; - 0.5 cm in the soy group; p = 0.0023), indicating enhanced lower body power. No significant changes were observed for upper (p = 0.38) or lower (p = 0.82) body strength, aerobic power (p = 0.16), body composition measures (p > 0.05), or salivary immune and inflammatory markers (p > 0.05) compared to the soy group. Reported incidences of illness were unaffected by bovine colostrum supplementation.
conclusionBovine colostrum may enhance neuromuscular performance, specifically lower body power, but provides limited benefits for other performance metrics, body composition, or immune/inflammatory function. Future research should explore bovine colostrum's potential during off-season training or under higher immune stress conditions.
