IgG is the single metric that most directly reflects colostrum's value. It neutralizes pathogens, supports gut barrier integrity, and drives every downstream benefit. Industry standard sits at 15–20%. Many brands don't disclose it at all — which is itself a signal. ORALEA holds a verified minimum of 40%, sourced from first-milking only, tested by independent labs every batch. Double the antibodies. No asterisk.

Loose colostrum powder is hygroscopic — it attracts and absorbs moisture from air. Every time a tub is opened, oxidation, moisture contact, and UV exposure begin degrading the very bioactives on the label. Yu et al. (2015) quantified this: IgG shelf life in powder exposed to air is approximately 1/5th that of sealed capsules — and the degradation rate constant for loose powder is 30× higher. Every capsule of Total Vitality is sealed at manufacture — 750mg, hermetically enclosed, no air, no moisture. Every capsule you take is as potent as the day it was made.

A key that's been melted still has the same metal. It just no longer opens anything. Heat denatures proteins the same way — the amino acid content survives, but the functional shape is gone. IgG begins losing that shape above 60°C. Spray-drying, the most common colostrum processing method, operates above 150°C. ORALEA is freeze-dried at low temperature from farm to bottle. No heat. No denaturation. Full function preserved.

Most supplement brands test once — at launch or during an annual audit — and apply that result to every subsequent batch that ships. ORALEA tests every production batch independently. IgG potency, heavy metals, microbial safety, and contaminant screening — verified every run by external labs, not us. Every bottle carries a QR code linked to our full testing results page. Find your lot number, see your batch's certificate of analysis. Not a brand-level result. Your specific production run.

Diet and environment directly affect the immunoglobulin profile of colostrum. Pasture-raised, grass-fed herds produce colostrum with a broader spectrum of IgG subclasses and higher micronutrient density than conventionally fed animals. Hormone-free — no rBST, no synthetic growth hormones. No antibiotics in contributing herds. And the calf comes first. Colostrum was produced for one biological purpose: to give a newborn everything it needs to survive. The calf receives its full required colostrum before any surplus is collected. That's not just an ethics statement — it's a sourcing filter.

41 out of 43 plastics tested released toxic chemicals into their contents (Zimmermann et al. 2021) — and fat-soluble supplements like colostrum are the most vulnerable to that migration. ORALEA ships in pharmaceutical-grade frosted glass with an aluminum lid, inside a cardboard outer tube that blocks UV from production to your door. Chemically inert. Zero leaching. Zero light exposure.
