Is this safe?

So my friend just had a baby and she knows I have been struggling with breastfeeding and she knows how badly I wanna continue when I say struggle I mean I only pump out 4oz in total and so I literally don't have a stash saved at all it's very little I wanna build it up she recommended this product to me by ITworks she says she takes it and her other friends do? What do you guys think has anyone tried this before
