Formula and transparency
Pineal Guardian lists 7 named ingredients: Yamabushitake (Lion’s Mane Mushroom), Spirulina, Pine Bark Extract, Chlorella, Elder Mahogany Neem, Ginkgo Biloba, Bacopa Monnieri. Synaptigen lists no complete ingredient list in our captured data. The two formulas do not share any named ingredients in our data. Only Pineal Guardian lists Yamabushitake (Lion’s Mane Mushroom), Spirulina, Pine Bark Extract, Chlorella, Elder Mahogany Neem, Ginkgo Biloba. One side publishes no ingredient list at all, so the formula comparison is limited to the documented side; the missing list is a transparency gap, not a neutral tie. Pineal Guardian has 1 documented red flag: exaggerated-claims. Synaptigen has no documented red flags in our data. Ingredient order and blend totals are not the same as per-serving doses; without a Supplement Facts panel, part of the formula remains unknown. A longer ingredient list is not automatically a better formula; disclosure, dose and evidence quality matter more than the count.
