“Customers appreciate the active form of B1 in this product, noting its fast-acting effects and pleasant taste. Many users report significant improvements in energy levels, clarity, and relief from conditions like restless leg syndrome, POTS, tinnitus, and anxiety. The tablets are small, dissolve easily under the tongue for better absorption, and have a slightly sweet taste. Some customers express concerns about certain ingredients like sodium citrate, citric acid, sorbitol, and mannitol causing digestive issues. Despite these concerns, the product is praised for its economical packaging and effectiveness at lower doses compared to other forms of B1. Overall satisfaction is high with many planning to repurchase.”
