Is Parshat Ha'Mon a segula or not?

Today is the day people consider it a segulah, or perhaps a better word would be a "yom mesugal", to say Parshat Ha'Mon - the psukim of the portion in the Torah describing the falling of the Mon, and how Hashem sustained the Jews in the desert for 40 years with this miracle manna.

The idea of the segulah is that this week is Parshat B'Shalach, in which the portion of the manna is found, and reading it is meant to remind us that it is Hashem who provides us with our sustenance, not our own toil and efforts, no matter how necessary and important they might be. With this reminder and reconsideration of the real source of sustenance, perhaps Hashem will be more inclined to give the extra assistance in providing the sustenance.

If you have not yet said the parshat ha'mon and still want to, Tefillos.com has the set the table for you...

And once on the topic, Kikar Shabbos has a write-up about how this segula is false. Basically it is recommended, and brought in Shulchan Aruch, that one should read the parshat ha'mon every day. There is no special power in reading it today, but should be read every day.

According to their research, the source for the segula is given as Reb menachem Mendel of Rimanov. yet when looking at the calendar of the year that prints all the minhagim, one will see that he says he spoke with the descendants and they deny his being the source and that they have no special minhag of saying it today.

The only source found for it, according to the article, is printed in a sefer that quotes someone who quotes Rav Shalom of Stropkov, who supposedly said in the name of Reb Menachem Mendel of Rimanov that it is a segula to say it on this day.
Their conclusion is that such a weak source cannot be relied upon to actually consider it a real segula.

Real segula or not, say it every day or not, any time you say, today or any day, it you should think about the source of your sustenance and reconsider that while you have to put in your effort, it is ultimately Hashem that provides parnassa, and hopefully reconsidering this will be a merit for Hashem's beneficial sustenance.
