The supplement industry is indeed the “Wild West” and there are a lot of snake oil salesmen out there with false claims and no ethical standards. Part of what inspired the creation of Neurohacker Collective was in response to this exact problem.
We have non-proprietary formulations - we publish exactly what’s in our product, with the exact amounts. We publish links to the research that support their safety and efficacy, which includes Phase II & III university and clinical trials, strong quantified self research data, and over 40+ years international research on nootropic stack formulation. We specifically designed our product with a set of ethical guidelines, so that we would avoid things like dependence or down regulation. In addition, the formulation was designed to produce long-term benefits to the brain, supporting the growth of new neurons, synaptic connections, neuroprotection, and so on.
