How many mg of ps100 do you get? is it a 500mg capsule of 60% standardized ps100 = 300mg? or is it a 300 mg capsule of 100% ps100?

Here was the email I sent to the manufacturer: The bottle says standardized to 20%. So there is actually only 60 mg of Phosphatidylserine per 300 mg serving? I’ve never seen “standardized” on this particular supplement before. There reply: Yes you are correct. All Phosphatidylserine are standardized, ours is standardized to 20%. I see this as a rip off compared to Jarrow, Doctor’s Best, and some of the other more reputable brands.

I'd like to see the first question answered as to the actual concentration of a serving, with or without standardization!

I ordered PS directly from double woods and the label on that bottle says “from non-GMO soy, Standardized to 20%

" Testing is available by request". Does this mean testing results are available? Just curious about the quality control assay results.

Hello, Yep! Just send an email to support@doublewoodsupplements.com for all testing or other order related requestions. Best Regards, -Caroline Double Wood Supplements
