About SAC

SAC restores our body’s natural balance and activates powerful healing potentials by triggering the cascade of hormonal responses which leads to calcium homeostasis. As the world’s first calcium-ion delivery system, SAC replenishes calcium ion which as the second messenger restores our body’s communication from cellular level up. 

Miracles happen when our body communicates clearly.


SAC Calcium is an innovative new bio-material based on calcium carbonate derived from small oyster shells.

Highly advanced process formulates it to maintain positive charges (2+) by altering the bonding structure, namely sigma anti-bonding. The positive charges of the molecule attract water molecules to cluster around it, making it incredibly water soluble and allowing direct and passive absorption into our body through channel protein of our membranes by diffusion.


About 50% of calcium in our blood is inactive. SAC calcium ionizes inactive calcium in our blood to be active.


SAC calcium helps maintain proper calcium level in the body by triggering thyroid hormone and parathyroid hormone.


SAC helps calcium to reach the ultimate destination- the bone.



Helps in detoxifying pathogens (includes cancer cells) and harmful substances in our body for prevention of cancer.




Helps in stabilizing calcium homeostasis by initiating bone formation and repair process for prevention of osteoporosis.




Helps in spreading calcium ions deep into the cartilage to restore and eliminate sources of pain for prevention of arthritis.

Rapidly Improving Kidney Function!

Years of dysfunctional kidneys sucked the life out of me and even turned my face into a deathly dark color. I tried everything from eastern to western medicines, but nothing seemed to help. Then at the plea of a close friend, I started taking Maragen. In about a month, I have noticed that my face turned back to normal and my body felt much better.

I thought it was the effects of all the medication I had been taking, and immediately stopped taking the Maragen. (I thought it was a bit pricey.) I felt good for a few days, but then my condition deteriorated slowly, and in about two weeks my face started to turn dark again. I got back on Maragen again and discovered how amazing and powerful the product was. Experiencing rapid restoration of my kidney functions and seeing my normal face again in the mirror is simply unbelievable! I thank my friend and Pronuvia for these wonderful products.

Saved from last stage colon cancer!

I had terminal colon cancer which was metastasized to both liver and bones. I was devastated and had little hope when I received radiation therapy twice and it did not have any effect. I had been taking only pain killers and sleeping pills. My cancer level in October 2015 was CEA 200. When I heard about the remarkable effects of Maragen on cancer from a close friend, I had to give it a try. I started on it since Oct. 2015, and my cancer levels dropped to CEA 49.1.

I could not believe it. On February 9, 2016, after taking Maragen for four months, all blood test results showed almost normal. This is truly remarkable. I am feeling much better, and continuing to get better.

My cancer is receding!

I grew 17cm in 8 months!

I was a short 10th grader at only 153cm. I could only reach to my friends’ chins. Then my mother got Osso Junior in October 2015. For two months I could not notice any changes. In the past, I had tried so many different things to grow taller, but they all failled. Not having better options, I decided to try Osso Junior for at least 6 months. Then in January 2016, I started experiencing a dramatic effect, I was growing taller! By August 20, 2016, my official height was 170cm! Everyone who saw me was amazed. I am amazed. Osso Junior is a miracle for me.

A golf ball sized tumor - gone!

I am a US Air Force pilot and one day got diagnosed with a brain tumor the size of a golf ball. I was devastated. However, when I heard about Maragen, I took it for three months beofre I got another brain scan at the Washington Bethesda Medical Center.

The doctor asked me incredulously,”How come I do not see the tumor?”

Maragen is a miracle supplement!
