You told us that the supplement Pineal Guardian X was the second in ranking among five we have asked about for preserving and improving cognitive function. Does it have any clinically significant antiviral activity within the central nervous system?

While you are doubting this, you have intuitively seen the reason this can be so very effective despite having only a modest delivery of nutritional substances and extracts from various sources of phytonutrients. There is much more to the story than known by existing science from the study of these plant materials and their properties. So you are leaping ahead, as they are, not only in recommending something of genuine value but adding more scientific insight than possible by current science itself, to understand how people can benefit despite appearances. And this is the key to understanding why they are circumspect. While they believe in the product and they have seen it help people, it is a mystery to them in terms of not knowing exactly what the magic ingredient or combination is doing the heavy lifting here. But having become convinced they are onto something important, are boldly proceeding despite being in the position of making promises which cannot be well-defended from a scientific perspective. They cannot point to specific scientific studies with modest amounts of the various constituents doing something of substantial benefit to improve cognitive function, so they are, in part, drawing from a long history of intuitive insight about the role of the pineal gland and its compromise as a source of trouble and limitation. This is one of those circumstances where divine insight and higher awareness can provide tremendous value in allowing a leap forward to gain benefit from something that might not ever be tried, based on limited awareness and knowledge alone as provided by scientific evidence and merit, constrained by doing only what is tangible and logical on its face.
