First time making an apple cider. Which yeast products are the best to use for cider? Is there any other alternative to brewer's yeast?
tl;dr: NO. Forget it. Ain't never no gonna work. Not for cider, not for beer, not for nuffin'.
Explanation:
Brewer's yeast sold as (part of any) nutritional supplement is usually spent yeast that has been sold off by one brewery or another to a food products manufacturer. It has been processed into a food supplement and as part of that process it has generally been heated to inactivate it. Translation: it's dead as a dodo. It won't have any viability left and can't be expected to ferment anything at all.
You might be able to use it as part of a yeast nutrient, though. Inactivated (read: dead) yeast makes up the bulk of various yeast nutrient blends.
As Philippe says, get a proper cider yeast.

Some nutritional/probiotic yeasts and bacteria are sold live, not all are dead. – dmtaylor Apr 18 at 12:20
The best brewer yeast to make cider is a cider yeast. Wyeast makes a few dry or liquid yeast for cider, which I tried and was satisfied with.
Alternatives are plenty, in fact any yeast can be used, but each will perform differently. For your first cider batch, I would play safe and use a proper cider yeast (like Wyeast STRAIN: 4766 CIDER ™).
Here is an article with alternatives: https://byo.com/article/yeast-selection-for-cider/
Someone here claims that Saccharomyces boulardii makes a decent cider. I haven't tried this myself and remain skeptical, but here is a link:

My favorite cider yeast is Red Star Cote des Blancs. Outstanding every time I have used it. And cheap, you can buy multiple packs on Amazon and they keep in the refrigerator for many years.
