No.... But we can get pretty close!
We advise all of our male fertility supplement customers to take a full seminogram, prior to taking our products and after 3-months of use. We also advise our female customers to test all of the key hormones associated with pregnancy. For our daily multi-vitamin & immunity supplements customers, we suggest getting a Vitamin Deficiency Blood Test with either Labcorp or Quest Diagnostics, and also running the same test after 3-months of use of our supplements.
However, we will never be able to fully prove our products work, because there's no way of being able to isolate what the physiological change, given that nutrition is one of a number of contributing variables to your health at any given moment in time.
We created Supplemena to be the "nudge", which might make the marginal difference towards your nutritional goals.
