Colostrum Powder

Intense training suppresses immune function for up to 72 hours post-run.

Bovine colostrum supplement for runners helps close that window by delivering 2,300mg of bovine colostrum standardized to 25% IgG (Immunoglobulin G) per serving, alongside naturally occurring growth factors that support gut barrier repair during high-mileage training blocks.

Bovine colostrum contains immunoglobulins, lactoferrin, and growth factors that support intestinal barrier integrity at the cellular level. Prolonged endurance running increases intestinal permeability, the mechanism behind runners stomach, post-race GI distress, and the recurring sickness that follows hard race efforts. At 400-800mg IgG daily, colostrum supplementation reduces exercise-induced gut permeability and supports mucosal immune defense, with the most pronounced effect during periods of high training load, heat exposure, or multi-day race recovery.

Built for marathon runners in high-volume training blocks, ultra runners managing multi-day race recovery, and any runner who regularly gets sick in the two weeks after a hard race or a major training block. Also relevant for runners dealing with chronic GI distress during long efforts, where intestinal permeability is the likely root cause.*

HOW TO USE

1. Daily maintenance: Mix one scoop (2,300mg) in 6-8 oz cold water or a post-run shake. Consume within 10 minutes of mixing.
2. Timing: Morning on an empty stomach or immediately post-run are the two windows used most in endurance research. Either works; consistency matters more than precision.
3. Race week and high-load phases: Begin supplementing 10-14 days before a target race to build mucosal immune support ahead of the post-race immune suppression window.
4. Allow 3-4 weeks of consistent daily use before assessing gut and immune response.
5. Stack: Pairs with L-Glutamine (5-10g post-run) as a gut barrier repair protocol. L-Glutamine provides the direct substrate for intestinal epithelial cell repair; colostrum supplies the immunoglobulins and growth factors. Use both during periods of high mileage or recurring GI distress.

For adults only.

FAQ

Q: Does bovine colostrum actually help with runners stomach?

A: Bovine colostrum contains IgG immunoglobulins, lactoferrin, and epithelial growth factors that support intestinal barrier integrity. Endurance running increases gut permeability - the mechanism behind GI distress, cramping, and runners stomach. Research shows bovine colostrum supplementation reduces exercise-induced intestinal permeability, particularly during hot conditions and high-load training. This product delivers 575mg IgG per serving. It pairs well with L-Glutamine, which provides the direct substrate for intestinal cell repair.

Q: How much colostrum should a runner take, and when?

A: 400-800mg IgG daily is the range used in the majority of endurance research. This product provides 575mg IgG per serving, placing it within that therapeutic range. Timing is flexible - morning on an empty stomach or immediately post-run. Allow 3-4 weeks of consistent use before assessing immune and gut response. The powder format mixes into a post-run shake; it is also well-suited to travel and race-week use.

Q: Can colostrum help with immunity during marathon training?

A: High-volume marathon training creates an open window of immune suppression lasting 24-72 hours after hard efforts. Bovine colostrum supplies IgG immunoglobulins that support mucosal immunity - the first line of defense in the gut and respiratory tract. Supplementing consistently in the 10-14 days before a race and through recovery may reduce the likelihood of illness during and after peak training blocks. This is particularly relevant for runners who repeatedly get sick after races.

Q: Is bovine colostrum useful for ultra runners managing multi-day GI issues?

A: Yes. GI shutdown is a primary cause of DNFs in events lasting beyond 50 miles. Intestinal permeability increases with effort duration, heat, and cumulative fatigue - all constants in ultra running. Bovine colostrum's IgG and growth factors support gut barrier function during extended efforts. Stacking 2,300mg colostrum with 5-10g L-Glutamine daily during a training block targets both the immune and structural components of gut barrier integrity.
