A complete dosing guide for lactoferrin supplementation — covering standard and advanced protocols, enteric-coated vs. liposomal forms, daily vs. pulsed dosing, and the best combinations with other longevity supplements.
Lactoferrin is not a supplement you take carelessly at whatever dose the bottle suggests. The difference between a dose that provides meaningful anti-inflammatory and immune-modulating effects and one that merely delivers an expensive placebo comes down to understanding three things: the form you choose, the dose you take, and how you integrate it with the rest of your protocol.
This guide is the clinical protocol companion to our Lactoferrin intervention overview (Good evidence) and our scientific review of lactoferrin and inflammaging. Here we get specific: exact doses, timing, form selection, stacking protocols, and monitoring biomarkers.
Clinical studies of lactoferrin supplementation in humans have used a range of doses, and the data suggests a clear dose-response relationship:
100 mg/day (low dose):
200–300 mg/day (standard dose):
400–600 mg/day (advanced dose):
Important caveat: Higher doses (>1g/day) can cause GI side effects including loose stools, nausea, and bloating in some individuals. Start at 200 mg and titrate up over 2–4 weeks.
If you want to see how lactoferrin fits into a complete evidence-based supplement stack, the Pragmatic Pioneer protocol is a useful reference — lactoferrin works naturally as the daily senostatic backbone alongside the periodic senolytic cycles already in that framework.
Surviving gastric transit is lactoferrin's primary pharmacokinetic challenge — stomach acid (pH 1.5–3.5) denatures intact protein, reducing bioavailability. Standard uncoated capsules lose an estimated 70–90% of intact lactoferrin to gastric degradation. However, the bioactive peptides generated during digestion (particularly lactoferricin, a potent antimicrobial and immunomodulatory peptide) retain activity in the gut and are absorbed in small amounts systemically.
When to use standard form: Primarily for gut health, microbiome support, or infection prevention in the gut. Also when cost is a primary constraint — standard lactoferrin costs roughly 50–60% less than enteric-coated forms.
Dose adjustment for standard form: To compensate for lower bioavailability, consider 400–600 mg/day to achieve systemic effects comparable to 200–300 mg/day of enteric-coated lactoferrin.
The enteric coating is a pH-sensitive polymer that remains intact in the stomach (pH <4) but dissolves in the small intestine (pH 6–7.5), releasing intact lactoferrin where it can be absorbed into circulation. This is the preferred form for systemic anti-inflammaging applications and is the format most aligned with the RCT evidence showing circulating cytokine reductions.
When to use enteric-coated: For the primary anti-inflammaging application — reducing IL-6, TNF-α, and supporting NK cell function in older adults. This is the recommended default for anyone over 50 using lactoferrin for longevity purposes.
Practical tip: Take enteric-coated lactoferrin 30–60 minutes before a meal. Despite the protective coating, taking it with food slightly extends gastric transit time, which may affect coating integrity at the margins. Before-meal dosing ensures it reaches the small intestine while stomach pH is not maximally reduced by digestive secretions.
Liposomal encapsulation in phospholipid vesicles (phosphatidylcholine, similar to cell membranes) provides the highest bioavailability by protecting the protein through both gastric and intestinal transit and potentially facilitating direct cellular uptake. Early pharmacokinetic studies show significantly higher plasma AUC (area under the curve — a measure of total drug exposure) compared to other forms.
When to use liposomal: If you have documented GI absorption issues (celiac, IBD, post-bariatric), or if you want maximum systemic exposure and are willing to pay 2–3× the cost of enteric-coated forms. Also appropriate for those combining lactoferrin with other liposomal supplements (liposomal vitamin C, liposomal glutathione) for a comprehensive oral delivery strategy.
Dose for liposomal: 100–250 mg/day is likely sufficient given the enhanced absorption; higher doses offer diminishing returns.
High-quality bovine colostrum contains lactoferrin alongside immunoglobulins, growth factors, and proline-rich polypeptides — a broader immune complex than standalone lactoferrin. The challenge is precise lactoferrin dosing: many colostrum products don't specify lactoferrin content, and concentrations vary significantly by product, batch, and processing method.
When to use colostrum: When you want the full spectrum of bioactive colostrum compounds (not just lactoferrin), or if you're using it for post-exercise recovery and gut health and the broader immune complex is the goal.
Lactoferrin dosing from colostrum: Look for products that explicitly state lactoferrin content. For a therapeutic dose (200+ mg), you'll typically need 2–4g of colostrum from a high-quality first-milking source. Pair with standalone enteric-coated lactoferrin if precise dosing is important. For a complete brand comparison across all three forms, see the Best Lactoferrin Supplements 2026 guide.
Unlike senolytics (fisetin, quercetin) which work through a "hit-and-run" mechanism requiring periodic high-dose pulses, lactoferrin's mechanisms of action favor consistent daily supplementation.
Recommendation: Take lactoferrin daily, consistently, at the same time each day. If budget is a constraint, prioritize daily dosing at 200 mg over periodic higher doses.
Avoid: Combining with high-dose iron supplements at the same time — lactoferrin will chelate the iron, which changes iron absorption dynamics. If taking both, separate by at least 2 hours.
This is the core protocol for someone 50+ focused on reducing inflammatory aging:
For those running periodic senolytic cycles alongside daily senostatic support:
Daily (continuous):
Monthly senolytic cycle (2 consecutive days):
Continue daily lactoferrin through and after the senolytic cycle. The senostatic (lactoferrin) and senolytic (fisetin/quercetin) mechanisms are complementary and safe to combine. For the full senolytic protocol, see our fisetin dosage guide.
For increased immune support during high-infection seasons or periods of increased stress:
Daily (year-round):
During high-risk periods (autumn/winter, travel, high stress):
To assess whether your lactoferrin protocol is working, test these markers at baseline and at 3–6 months:
Tier 1 (Essential):
Tier 2 (Recommended for 60+):
Tier 3 (Advanced):
Subjective tracking:
