I’ve been taking N°4 Focus each morning before work—after a few days I noticed improved clarity during long Zoom sessions and felt sharper when multitasking. Memory recall feels crisper, too.”The inclusion of Lion’s Mane, Ginseng, Ginkgo Biloba, Bacopa Monnieri, CDP choline, and a B‑complex vitamin blend delivers a clean boost to concentration without any jitteriness—unlike coffee or caffeine supplements. It tastes slightly bitter down the throat, but I simply keep water close by and it’s manageable.**---✅ Why it works for mePowerful herbal combo: Lion’s Mane and Bacopa support cognitive clarity and memory processing, though effects typically build over several weeks.Ginseng and Ginkgo Biloba may aid focus and circulation in the brain, though broader scientific support is still evolving.CDP Choline (Citicoline) is well-regarded for memory and learning support—especially in older adults.B‑vitamins, iron, zinc, and guarana caffeine support mental energy and reduce fatigue. ### ⭐⭐⭐⭐⭐ Helps you to focus *by on Reviewed in the United Kingdom 11 August 2022* It does what it says it does. It did help me focus and finish tasks quickly. I feel like it also boosts my short term memory. The only downside is the taste, horrible taste. Not sure how they can make it better without compromising its quality. It's also important to note that this has caffeine in it. So for those who suffer from anxiety, you can feel you are a bit more on the edge when you take it. I would say cut down on your caffeine intake when you start taking this. ### ⭐⭐⭐ Not for everyone *by on Reviewed in the United Kingdom 3 September 2022* Product work but is smell bad and I found this difficult to swallow and take it regularly. ## Frequently Bought Together - N°4 Focus - Nootropics Brain Supplement - with Lions Mane, Ginseng and Ginkgo Biloba, Bacopa Monnieri, CDP Choline, Vitamin B Complex - Cognitive Enhancer for Concentration & Memory - 60 Capsules - N°12 ANTIFLAMM - Anti-inflammatory & Joint Health with Boswellia Serrata Horsetail MSM Capsules High Dose - with Gotu Kola & Ginger Extract - 120 Capsules - N°9 Sugar FIX - Blood Sugar Control Supplement - Cinnamon Capsules with Bitter Melon, Beta Glucan & Chromium - 60 Capsules - Vegan Glucose Support Supplement - Blood Sugar Diet - Made in Germany --- ## 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.vn/products/259640576-n-4-focus-nootropics-brain-supplement-with-lions-mane-ginseng](https://www.desertcart.vn/products/259640576-n-4-focus-nootropics-brain-supplement-with-lions-mane-ginseng) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-05*
