Results reported by Serrano et al. showed that a liposomal bovine LF supplement containing 32 mg of LF orally administered at 4 to 6 doses/day for 10 consecutive days, accompanied by two to three daily 10 mg zinc doses, resulted in 100% recovery of 75 symptomatic SARS-CoV-2 positive patients within 4–5 days, and the same treatment at lower dose seemed to have prevented the disease in healthy contact (Serrano et al., 2020). Unfortunately, that study did not offer any immunological biomarkers related to the COVID-19 infection levels before and after treatment. Campione et al., 2020b assessed the efficacy of a liposomal formulation of apo-bLF in 32 COVID-19 patients with mild-to-moderate disease and COVID-19 asymptomatic patients. The scheduled dose treatment of liposomal apo-bLF for oral use was 1 g per day for 30 days (10 capsules per day, each one containing 100 mg of apo-bLF in liposomes) in addition to the same formulation administered intranasally 3 times daily (nasal spray contained about 2.5 mg/mL apo-bLFin liposome). On day 0, 15, and 30 of the study, rRT-PCR was performed to detect the SARS-CoV-2 presence; the complete blood count and chemistry panel (liver and kidney function), iron panel, coagulation profile, IL-6, IL-10, TNFα, and adrenomedullin serum levels were also evaluated. On day 15, 10 patients (31.25%) were clear from the SARS-CoV-2, while on day 30, all patients showed a viral clearance. On day 15, 5 patients previously symptomatic became asymptomatic, with a total of 17 asymptomatic and 15 symptomatic patients. On day 30, the other 6 patients, previously symptomatic at the 15-day period, became asymptomatic, resulting in a total of 23 asymptomatic patients (Campione et al., 2020b) .
Sounds like a range of Lactoferrin somewhere between 100 mg. to one gram per day.
A pint of cow’s milk runs about 100 mg.
Camel milk has about five times more lactoferrin.
Human milk has a bit more than camel, about seven times that from cows.
The very first milk after birth (colostrum) has the most.
Commercial lactoferrin supplements seem to run from around 100-500 mg. per pill.
Apo-lactoferrin seems to be the preferred type, regardless of what type of milk it is sourced from (pretty much all commercial supplements are bovine).
