Using this product in combination to antibiotic therapy and a Lyme healing lifestyle, within just a few months, CD57 results showed an NK cell increase from 11 to 55. Doctors were pretty amazed by the short turnaround/improvement to my NK cell counts. I do not know for sure what contributed to my epic health improvements but since this supplement was used in addition to the conventional and recommend treatments that most established Lyme patients already implement, i believe this supplement could be the reason I surpassed expectation and why my NK levels sky rocketed. ## Frequently Bought Together - Life Extension NK Cell Activator™, Immune Support, Natural Killer Cell Activity, enzymatically Modified Rice bran, Non-GMO, Vegetarian, 30 Tablets - Life Extension NAD+ Cell Regenerator and Resveratrol Elite, NIAGEN nicotinamide riboside, Trans-resveratrol, quercetin, Fisetin, for Longevity, Energy, and oxidative Stress, 30 Vegetarian Capsule - Life Extension Senolytic Activator®, healthy aging, cellular health support, bioavailable quercetin and fisetin, apigenin, black tea theaflavins, gluten free, non-GMO, vegetarian, 36 capsules --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/11748765-life-extension-nk-cell-activator-immune-support-natural-killer-cell](https://www.desertcart.is/products/11748765-life-extension-nk-cell-activator-immune-support-natural-killer-cell) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-05-10*
