She did NOT recommend this specific product, but in my research about the condition, it appeared this may also help along with the other things she has recommended. My results overall have been highly appreciated since I began treatment almost 8 months ago. The problem with rating this product is that I don't know which of several things is having a positive effect, and I've been unwilling to stop taking one at a time to try to eliminate any that aren't working. And it may be that it's the combination with the other supplements (and prescription treatment). Suffice it to be said that the combination of everything, including this product, is having a very positive effect on this over-70 male (enough said LOL!). And my physician approved of this product when I asked her before ordering it. She was aware of some of the research backing it, but had not had any specific experience with this product, however. Based on overall results (which I'd consider 5-star overall if reviewed), I can't single out this one product because it's part of a whole treatment regimen. But based on research on the ingredients with problems often associated with older males (not just E.D.), along with the combined results that have improved since I added this and one other supplement to my daily mix, I have to give it at least a 4-star rating. It's well worth trying if you need it but don't want to take any more prescription medications than necessary (including that "little blue pill"). ## Frequently Bought Together - Source Naturals L-Arginine L-Citrulline Complex, Essential Amino Acid Supplement, Supports Peak Performance* 1,000 mg - 240 Tablets - Nutricost Creatine Monohydrate Micronized Powder 500G, 5000mg Per Serv (5g) - 100 Servings, 17.9 Oz - Magnesium L Threonate, Magtein™, Sleep and Cognitive Support – High Absorption – Most Bioavailable Form of Magnesium – 2,000 mg – 120 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.co.th/products/1646175-source-naturals-l-arginine-l-citrulline-complex-essential-amino-acid](https://www.desertcart.co.th/products/1646175-source-naturals-l-arginine-l-citrulline-complex-essential-amino-acid) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-28*
