NK-Stim by Ortho Molecular Products

If you keep catching every respiratory virus at the office or on flights, a natural killer cell supplement is a reasonable experiment. It fits teachers, healthcare workers, frequent travelers, and high‑stress or low‑sleep periods when your first-line defenses lag. It also suits low-zinc eaters (plant‑forward diets or heavy sweaters) if your Zinc, Plasma or Serum runs low. Track sick days and consider hs-CRP (a general inflammation marker) if you want data to judge benefit over 4 to 8 weeks.

Larch arabinogalactan is a soluble fiber that signals through gut immune tissue and feeds microbiome species that make short‑chain fatty acids, which in turn nudge natural killer (NK) cells to act more efficiently. Olive leaf standardized to 20% oleuropein provides polyphenols that temper excessive cytokine signaling (the immune “text messages”) while preserving antiviral activity. Zinc bisglycinate supplies a well‑absorbed 10 mg dose of zinc, a cofactor immune cells need to mature and function. Aloe vera gel extract delivers acemannan‑rich polysaccharides that modulate macrophages and NK cells without the laxative anthraquinones found in aloe latex.

Use 2 capsules twice daily with meals to reduce stomach upset. Most people need a 4 to 8 week trial to judge changes in sick days or symptom intensity; some notice steadier respiratory health within 2 to 4 weeks during high‑exposure seasons. Zinc here is a maintenance‑level dose, so if your Zinc, Plasma or Serum is meaningfully low, correct that separately under clinician guidance, then continue this for upkeep through the winter or travel blocks.

Separate zinc by 2–4 hours from tetracycline or quinolone antibiotics and from levothyroxine, since minerals bind these drugs. Olive leaf can modestly lower blood pressure and blood sugar; monitor if you use antihypertensives or diabetes medication. Transplant recipients and those on immune‑suppressing drugs should avoid immune‑stimulating blends. Active autoimmune flares warrant caution and clinician input. Pregnancy and breastfeeding: avoid aloe internally unless your obstetrician agrees, and do not use aloe latex forms.
