It arrived in a difference of 2 working days. You feel the difference immediately before/after. I always recommend liposomal technology bio-products to everyone, with the aim of avoiding the injectable form, which is administered incorrectly many times.

Liposomal technology makes the bioavailability index of the vitamin higher than that of this pill. How does this happen? - This is achieved by encapsulating the vitamin in phospholipids, similar to those that make up the cell membrane of living organisms. What is the difference between a pill and liposomal technology? - The pill belongs to the category of "pro-drugs," meaning that after swallowing, it must first undergo the process of breakdown by the stomach acid, and then with the help of the "intrinsic factor" and insulin, be converted into its final form, which can then be transported through the blood and subsequently into the cells. On the other hand, liposomal technology bypasses this entire metabolic need/process, using these lipids to conceal them from the body's/blood's white blood cells, and also makes swallowing unnecessary as it is absorbed through the sublingual mucosa.

The main reason that liposomal technology is preferred over pills is that a sufficient number of the human population has a genetic deficiency in the secretion of the intrinsic factor, but also the avoidance of the metabolic process contributes much more to the adequate absorption of the vitamin.
