Flax Lignans and slowing loss

[dan65]

I have read a couple places that there was a small study that the flax lignan SDG which is found in flaxseed oil slowed the progression of hairloss. I was wondering where I could go to get a flax lignan supplement with SDG in it. I tried drug stores and they had flaxseed oil, but there was no mention of SDG or lignans. I believe the study had them take 50 mg a day of the SDG lignan. So I would want to take at least that. Thanks for the help
