SunTheanine proved useful for consistently improving deep restful sleep and consistent bowel regulation as reported by a client with Parkinsons. Replaced the use of OTC fiber supplements.

I truly love Master Supplements. Their products are of outstanding quality — you can feel the difference. What makes this company even more special is their commitment to education and integrity. They don’t just sell supplements; they teach you how and why they work, empowering practitioners and clients alike. As a Functional Health Practitioner, I deeply appreciate their science-based approach and the care they put into everything they do. Master Supplements is not only a brand I trust — it’s one I genuinely admire.

I checked the ingredients and was surprised that Aspergilis niger was one of your ingredients. I believe that it is not good for the body because it comes from mold. Please respond

Hi Geralyn, I am so sorry that this wasn't responded to sooner via this review platform but hopefully you were able to contact one of our staff members via phone or e-mail to get an explanation. Some enzymes are fermented of off substrates like bacteria, yeast, and other microorganisms. After the fermentation process the original substrate material is no longer traceable in the enzyme itself. I hope this helps!
