I discovered the educational videos. They are valuable to gain an understanding of the products. The Lumbrokinase that you have tested well. It use to be you could get higher strengths. But lately it is difficult to find the potency. I am glad I discovered yours.

I wanted the 50 unit product I got the 30 unit product. It was not made clear to me when I ordered that I'd receive the 30 unit product. I am wondering what the 30 unit is about. Anyway,I ordered the 50 unit from Professional Supplement Center so I would get what I wanted.

I am so sorry for the delayed response on this review platform but perhaps you were able to get into contact with our Customer Service team? Since 2003 we have had our 30 capsules versions and they are excellent products, the Doctor and Patient versions, do have 50 capsules and are more expensive for a bottle but you do save on the per capsules price. For all of our products we have a full money back guarantee and since it has been so long I feel obliged to send you a free bottle. Again, sorry for the confusion while ordering and not getting back to you sooner!

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.
