Unfortunately, however, your thymus begins shrinking after puberty, producing less Thymic Protein A as you age. **Q: Why do I need ProBoost?** A: ProBoost exists to take over where your thymus gland stops—providing complete, fully-intact Thymic Protein A to help keep your immune system functioning properly. **Q: Who should take ProBoost?** A: Anyone who is concerned about maintaining optimal immune system function will benefit from taking ProBoost Thymic Protein A. **Q: How do you take ProBoost?** A: Take ProBoost sublingually (powder/tablets) for optimal absorption or as a capsule with water for intestinal absorption. Use 1-3 times daily or as directed by your healthcare practitioner. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by K***E on August 7, 2018* ### ⭐⭐⭐⭐⭐ Review *by H***S on January 13, 2026* ### ⭐⭐⭐⭐⭐ Review *by L***E on June 16, 2018* ## Frequently Bought Together - ProBoost, 4 McG Thymic Protein A (TPA) Powder Packets - All Natural, Non-GMO, Immune Regulation and Support Supplement - 60 Packets, 4 McG TPA/Serving - Genex Formulas NAD+ 250mg Serving 60 Capsules Nicotinamide Adenine Dinucleotide (Actual NAD+ Not a Precursor) (1) --- ## 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.jp/products/517247677-4-mcg-thymic-protein-a-tpa-powder-packets-all-natural](https://www.desertcart.jp/products/517247677-4-mcg-thymic-protein-a-tpa-powder-packets-all-natural) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-22*
