Bought some vitamin D drops (liposomal) that say to take under the tongue. Now it’s surprisingly hard to actually do that. So how much am I missing out if it’s in the general mouth or on top of the tongue?
(I might try doing it in front of the mirror.)
Get some smoked salmon instead of ingesting tablets. Tasty, cheap AND healthy.
