About Douglas Labs - Colostrum

Douglas Labs Colostrum delivers bovine colostrum — the nutrient-dense first milk produced after birth — standardized to provide immunoglobulins (IgG), lactoferrin, and growth factors that support immune and gastrointestinal function. This practitioner-grade formulation is designed for individuals seeking targeted support for gut barrier integrity and immune resilience.

Why It's Worth Considering: Douglas Labs sources colostrum standardized for immunoglobulin content, ensuring a consistent and measurable delivery of bioactive proteins rather than an unstandardized raw powder.

Who Benefits

Best For

  • Adults seeking colostrum to support healthy gut mucosal integrity
  • Individuals using colostrum to help maintain immune defense year-round
  • Athletes looking to support recovery with bovine colostrum immunoglobulins
  • Practitioners protocols requiring colostrum for GI barrier and immune function

Cautions

  • Known allergy to any ingredient (check label)
  • Currently pregnant or breastfeeding (consult healthcare provider)
  • Taking prescription medications (check for interactions)
  • Under 18 years of age (unless recommended by pediatrician)

Frequently Asked Questions

  • Store in a cool, dry place away from direct sunlight. Most supplements are stable at room temperature (59-77°F). Keep the bottle sealed between uses. Check the label for any specific storage requirements — some probiotics and oils require refrigeration.

  • Most supplements can be taken together safely. However, some minerals compete for absorption (zinc and iron, calcium and magnesium) and should be taken at different times of day. If you're taking prescription medications, consult your healthcare provider about potential interactions.

  • Most supplements benefit from consistent daily use over 2-3 months to achieve full effect. Some (like vitamins and minerals) can be taken indefinitely as part of a daily routine. Others (like specific herbs) may benefit from cycling. Follow the product's recommended protocol or consult a practitioner.

  • Fat-soluble supplements (vitamins A, D, E, K, omega-3, CoQ10) should be taken with a meal containing fat. Water-soluble supplements (B vitamins, vitamin C) can be taken anytime. Minerals are generally best absorbed with food. Probiotics should be taken with or just before a meal. Check the product label for specific timing recommendations.

  • Track your specific health goals — energy levels, sleep quality, joint comfort, digestion, mood, etc. Most supplements take 2-8 weeks for noticeable effects. For objective measurement, baseline lab tests before starting (and repeat at 3 months) provide definitive evidence. The Gabriel Score incorporates clinical evidence for expected outcomes.
