Was comparing these 2 boron supplements and was wondering if they both contain the same active ingredient?
Natures way: Boron (as Boron amino acid chelate)
Pure encapsulations: Boron (as boron glycinate)
I would assume so based on this:
Chelation, in relation to this subject, is the pharmaceutical process of bonding a mineral to an amino acid. When this is done, the absorption and "bioavailability" of the mineral may be increased, meaning that the delivery of the mineral and its usability by the body can be enhanced:

yep, they are both boron.
i would go with the pure encapsulations brand. glycinate is one of the better chelates (from what i have read).
with the nature's way supp, you do not know what the chelate is, they probably go with the cheapest product they can get (which could vary between batches).
i prefer to know what has been used as the chelate, going with glycinate if i have the chioce (& avoiding excitotoxin chelates like aspartate, glutamate & cysteine (tho i've never seen cysteine used as a chelate in a supp), just a personal (paranoid perhaps) thing).
the cheaper supp brands tend not to list the chelate info. & when you email them, probably tell you its propriety info.
Glycine is an amino acid, glycinate means it's a salt of glycine. You can form a chelate with any amino acid.
If it doesn't say "glycinate" on the bottle, I wouldn't assume that it's just a glycinate chelate. Boron in aspartate form could be described as an "amino acid chelate", which is probably a bioavailable / useful form, though I think glycine is a friendlier amino acid.
