I've been using Lumultra for a while and it's been a fantastic help in boosting my focus and productivity. Before Lumultra, I struggled with mental fog and staying focused on tasks on hand, but now I start my day with clarity and maintain a steady level of energy through the afternoon. Occasionally, I would take Nova with Lumultra to give me the extra boost. It doesn't give me jitters like caffeine, and I've noticed an improvement in memory recall too. Lumultra has definitely made a positive difference in my daily cognitive function.
