Alpha-GPC 99% vs 50% powder

The serving size is different on our 50% compared to our 99%. It's 600mg vs. 300mg. The amount per serving is the same, though; as that is the amount of active ingredient per serving. That is how a Supplement Facts panel should be displayed. You list the serving size, then you list the amount of active ingredient per serving in that separate section.

Alpha-GPC is a bit weird because of its hygroscopic nature. The 99% is very rarely used/sold by anyone, due to how fast it can pick up moisture. Luckily we are in Arizona where it is extremely dry, and we take extra precautions when handling the 99%. We also seal the jars in a separate bag to ensure no moisture can get in at all. If you live in a dry area, and can take the precautions to ensure it doesn't get exposed to moisture, most people prefer using the 99% powder. The 50% is much easier to use and store, though. Either way, the potency is the same for each. It's just the dosage that needs to be adjusted.
