Colostrum for Health & Longevity

Created on 09/19/2026 – Quick Reference based on Evidence Review created using AI4L / Opus 5 – Audit

Dried cow's first milk; digestion destroys nearly all of it, so it works inside the gut. Fewer cold-like symptom days in heavy training and shorter infectious diarrhoea hold up; muscle, skin and hair claims are conflicted or untested. Most products dose far below the trials; harms are milk allergens and contaminated batches. (Full Review)

Protocol

Standard research dose
20–60 g/day
10–20% immunoglobulin G gives 2–12 g of antibody daily; most products supply 1–6 g/day.
Split dosing
Twice or three times daily
The dominant protocol; divided doses keep antibody in the gut longer.
Best time of day
Morning, empty stomach
The most common recommendation; trials used fasted and post-meal dosing. Liquid below about 60 °C only.
Time to effect
Illness days
8–12 weeks
Cold-like symptom-day reductions were measured over this span.
Gut permeability
Days to 2 weeks
The earliest shift, and largest where the barrier is already disrupted.
Strength and bone markers
8 weeks
Leg press gains and less bone breakdown in adults over 50.

Benefits

Contraindications
  • Cow's-milk protein allergy of any severity
  • Galactosaemia
  • Active immunosuppression, unless the product is documented as heat-treated
  • Competitive athletes under World Anti-Doping Agency jurisdiction without a batch-certified product
  • Chronic kidney disease stage 4 or worse (estimated glomerular filtration rate below 30 mL/min/1.73 m²) on a protein-restricted diet
  • Severe lactose intolerance, unless the preparation is lactose-reduced
  • Pregnancy and breastfeeding
    •
Key Interactions
  • Oral antibiotics (tetracyclines, fluoroquinolones such as ciprofloxacin): two-hour separation
  • Levothyroxine and oral bisphosphonates (alendronate, risedronate): four-hour separation
  • Oral iron supplements: two-hour separation, follow-up ferritin
  • Proton pump inhibitors (omeprazole, esomeprazole): may increase effect and digestive symptoms
  • Non-steroidal anti-inflammatory drugs (ibuprofen, naproxen, indomethacin): additive benefit
  • Other gut-barrier supplements (L-Glutamine, zinc carnosine, Saccharomyces boulardii): additive
  • Colostrum-derived lactoferrin supplements: additive
    •

Risk & Side Effects

  • High: Allergic reaction in people with cow's-milk protein allergy
    •
  • Medium: Digestive intolerance
    •
  • Low: Raised insulin-like growth factor 1 and anti-doping uncertainty; heavy metals; pathogens in raw product
  • Speculative: Growth-factor stimulation of existing tumours; immune activation in autoimmune disease

Monitoring

Marker Target Why
Fecal calprotectin Below 50 µg/g Gut wall inflammation; room to benefit
Urinary lactulose/rhamnose or lactulose/mannitol ratio No established target; change from baseline The only direct measure of the mechanism
High-sensitivity C-reactive protein Below 0.5 mg/L Whole-body inflammation, downstream of the barrier
Serum insulin-like growth factor 1 Lower-to-middle of age range; 100–160 ng/mL at 40–60 Confirms the product is not raising it
Serum immunoglobulin A 90–400 mg/dL Selective deficiency changes the expected mucosal response
Complete blood count with differential Lymphocytes 1.5–3.0 × 10⁹/L; neutrophil:lymphocyte below 2.0 Baseline immune capacity; drift on long-term use
25-hydroxyvitamin D 40–60 ng/mL Deficiency confounds the illness outcome

Cadence: Baseline fasted, then 8 weeks, 6 months, annually; insulin-like growth factor 1 once at 8 weeks.

Qualitative Assessment

  • Days per season with sore throat, congestion or cough, recorded contemporaneously
  • Bloating, stool form and post-meal discomfort, both the main side effect and a target outcome
  • Tolerance of foods that previously caused symptoms
  • Recovery time between hard training sessions during an intensified block
  • Energy through the afternoon, and whether illness now interrupts a training or work week
