After taking this for a week, I can say that I feel more alert and mentally focused. ### ⭐⭐⭐⭐⭐ You can cut these! An absolute Godsend! *by J***S on February 19, 2026* The only l-tyrosine supplements I know of that can be cut in half! 500mg a day is way too much for me but I found that 250mg does the trick! ### ⭐⭐⭐⭐⭐ This supplement has been a life changer for me to restore my energy. *by M***N on October 19, 2020* It was suggested by my physician to supplement with L-tyrosine to boost my thyroid function (i was low normal). What an improvement in energy and mood. Although these are 500 mg tablets, i cut them in half, and that seems better suited for my needs. ## Frequently Bought Together - Source Naturals L-Tyrosine -Free Form Amino Acid Supplement - 100 Tablets - Source Naturals Serene Science GABA, for a Calm Mind, 750mg - 180 Capsules - Source Naturals L-Tryptophan, for Mood, Relaxation, and Sleep*, 500mg - 120 Tablets --- ## 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.hr/products/1975602-source-naturals-l-tyrosine-free-form-amino-acid-supplement-100](https://www.desertcart.hr/products/1975602-source-naturals-l-tyrosine-free-form-amino-acid-supplement-100) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-24*
