Marah Natural is owned by Marah Deo Holdings.

Sigma Anti-bonding Calcium (SAC) is a revolutionary technological advancement that is changing lives with its passive calcium delivery system. While other forms of calcium delivery struggle in areas of absorption, SAC safely increases bone density naturally by awakening the body’s own bone-formation process.

Marah Natural products are manufactured in Coquitlam, British Columbia, Canada.

Our signature Sigma Anti-bonding Calcium technology is based on calcium carbonate derived from small oyster shells only found in Northern British Columbia, Canada. Our products are sustainable, naturally derived, and locally sourced.

Some of our elemental ingredients such as zinc and magnesium are chemically extracted from natural sources. We do not use Genetically Manufactured Organisms.

Yes. Marah Natural’s products feature our proprietary SAC Formulation Technology: the world’s first true ionic calcium, that is safe to use. Marah Natural has been tried and tested by over 100,000 customers from around the world who come in different ethnicities, gender, age and size. Unlike traditional calcium supplements our products have no known side effects and does not cause any calcification.

Our clinical trials are currently in progress. We are conducting the study of SAC’s role in multiple myleoma and erythropoietin-induced osteoporosis with the University of Arkansas for Medical Sciences in the USA and Clinical collaborative research of CBHI and Hallym University on the bone density increase by SAC in postmenopausal women with Hallym Univeristy in South Korea. 

Although our clinical trials are still ongoing. So far the results we have received from the University of Arkansas has been promising. We found that “the life span of mice with Multiple Myeloma could be extended from 50 days to 62 days via SAC IV. If we compare this to human life expectancy, we expect to extend the lifespan of humans by 20% or more. In addition, we saw a significant increase in bone density in the additional 8-week clinical trial confirming a 5% increase in BMD.” Showing the great potential SAC could deliver in improving bone health and lifespan.

Rest assured, Marah Natural has been tried and tested by over 100,000 customers from around the world already with raving results.

No. In our research and customer trials we found that the key to our innovative formula relies on including a golden ratio dosage of SAC calcium and other minerals. Several studies have found that excess calcium supply in our body can lead to calcium overdose which can cause calcification, degenerative diseases and lead to serious health conditions. Our ability to absorb minerals depends on our body weight, quality of lifestyle and also in the quality of the supplement - and Marah Natural’s innovative SAC Formulation Technology offers the world’s first true ionic calcium - that is safe and natural to use.

Health Canada only approves and gives NPN numbers to Calcium product that has at least 300 mg of Calcium. Our research and numerous customer trials has shown that including 300 mg or more of Calcium is not effective, therefore, we had to be approved as a Selenium supplement with SAC supplementing the product.

Health Canada only approves and gives NPN numbers to Calcium product that has at least 300 mg of Calcium. Our research and numerous customer trials has shown that including 300 mg or more of Calcium is not effective, therefore, we had to be approved as a Vitamin D supplement with SAC supplementing the product.

Let’s assume you are 154 lbs (70kg). In your body, you have about 1.2 kg of calcium. A healthy body’s Calcium quantity is approximately 1-1.3kgs according to male and female. Bone is composed of Calcium, Phosphorus, Magnesium, Collagen and Water and makes up 12-15% of body weight. Normally, if you weigh 70kg you have about 3.5L of blood. And in the blood, you have about 350mg of calcium and among the calcium, the physiologically active calcium is about 175mg Imagine you taking 500mg to 1000mg of calcium per day. That is an overdose which will cause problems like calcification.

1. For a healthy person without any health conditions: we recommend taking one dose per day, mixing 5 ml of SAC with 500 ml of water and taken on an empty stomach  

2. For patients with chronic conditions: we recommend taking one dose twice per day, mixing 5 ml of SAC with 500 ml of water and taken on an empty stomach  

  3. For children: we recommend taking one half-dose per day, mixing 2.5 ml of SAC with 300 ml of water and taken on an empty stomach

There is no recommended maximum daily dose for our product. 

Please refer to appropriate sources for the latest information about the principles and guidelines of adequate dietary intake of calcium and supplementary ingredients listed on the product. 

Our supplements must be taken on an empty stomach to prevent interaction with food and strong stomach acid. We suggest taking the dose 1 hour (or at least 30 minutes) before meals. Some people prefer to take our products first thing in the morning (before breakfast) and some prefer to take it between meals. Since SAC may induce frequent urination, we recommend it be taken before bed.

Products must be stored in a cool place away from direct sunlight. Depending on the storage temperature, precipitation may naturally accumulate in the bottom of the bottle. This will dissolve upon shaking and does not affect the potency of the product.

When the product is unsealed, used, and closed in normal circumstances, the products are guaranteed to perform as intended for six months.

But when the product is opened and left unclosed, the product can last up to 7 days but loses the potency. Do not leave it open.

We recommend a 1:100 ratio of SAC to water for optimum absorption by diffusion. Mixing the product with less water does not make the solution stronger, but does decrease the absorption rate, making it less effective. The interaction between water molecules and SAC makes SAC absorbable. Taking SAC without mixing it with water will render it ineffective.

Once mixed, we recommend that the product be taken within one hour. However, for dialysis patients with kidney problems, intake may be spread out over many hours, as long as the stomach is empty.

In addition to 28 types of minerals, raw material contains 50 plus types of minerals including trace minerals, however, in most actual cases, it may not become analyzed due to limits on the analytic device.  The result is compounded by processing with 1/200 of usage. First, Magnesium, Zinc is artificially added because they are generally necessary to be supplemented.   The focus of our product is Calcium, not mineral.   Generally, mineral is mostly possible for intake by having a balanced diet.   When marketing our product if we focus on mineral content, the meaning of SAC fades out, so it would be better to appeal as produced using SAC although it is officially Selenium.

Within a small quantity of liquid, it is not difficult to raise density of a matter to a certain density by spending time, but it becomes exceedingly difficult when it is attempted to raise to an even higher level.  It takes a long time and the production environment needs to be changed precisely.

2.5mg, 5mg of SAC absorption rate is possible up to 99%. After you consume SAC the internal pH is changed, thereby radically increasing absorption of Calcium we intake through passive transport movement.  There is a large quantity of Calcium in anchovy, cheese, and beef soup, but it is a solid compound of Calcium Phosphate, namely a compound with an ionic bond.  It is not easy to ionize this for internal absorption, especially in an acidified body fluid with a large quantity of reactive oxygen.  All Calcium compounds of Calcium products are compounds with strong ionization, and it is relevant how much is ionized and absorbed as biological Calcium in body.  SAC Calcium has over 200 times of ionization compared to general Calcium.   Namely, Marah Natural’s Ion Calcium means not that Calcium is already ionized, but that it is easily ionized.   It is impossible to have ionized metallic substance.   For Calcium, when dissolved in water, it becomes only 1/10 x 100000000. What is ionization?  For example, salt, namely NaCl is an ionized matter of Na and positive ion Cl interacting to become a negative ion.  Na interacts as a positive ion and Cl as a negative ion to become a compound.  This is called an ionic bond.  This compound is not called an Na ion salt just because Na is a positive ion.

A healthy body’s Calcium quantity is approximately 1-1.3kgs according to male and female.Bone is composed of Calcium, Phosphorus, Magnesium, Collagen and Water and makes up 12-15%of body weight.Normally, if you weigh 70kg you have about 3.5L of blood. And in

the blood, you have about 350mg of calcium and among the calcium, the physiologically active calcium is about 175mg Imagine you taking 500mg to 1000mg of calcium per day. That is an overdose which will cause problems like calcification.

Ionized Calcium dissolved in water is 200 times stronger compared to general Calcium. Maintenance period:   It may be over ten days in vacuum, but it is about one day after exposure to air when dissolved.  In a covered glass jar, it will last over six months.  Oxygen is permeated in a plastic bottle so it does not last long.

Marah Natural is trying to shift the paradigm in the Calcium supplement industry. That is why we are partnering with institutions like CBHI to keep up with the up to date knowledge on Calcium and bone health. This leads to the question: how does 3.5mg of Calcium can help  us?  Let’s assume you are 154lbs (70kg).  In your body, you have about 1.2 kg  of Calcium. A healthy body’s Calcium quantity is approximately 1-1.3kgs according to male and female.  Bone is composed of Calcium, Phosphorus, Magnesium, Collagen, and Water and makes up 12-15% of body weight.     Normally, if you weigh 70kg you have about 3.5L of blood. And in the blood, you have about 350mg of Calcium and among the Calcium, the physiologically active Calcium is about 175mg. If you absorb 99.% of 3.5mg SAC, that means your physiologically active Calcium will increase to 178.5, but you will always lose some calcium if you exercise a lot or if you have a bad diet and such. So, this will balance out and keep your calcium level to be simply perfect.Imagine you taking 500mg to 1000mg of Calcium per day. That is an overdose which will cause all sorts of problems like calcification.

In conclusion, Health Canada only approves and gives NPM numbers to the Calcium product that has at least 300mg at the moment. Therefore, we had to be approved as a Seleniumsupplement with SAC supplementing the product.

We are an independent Canadian company that research, develops, manufactures and markets our own Marah Natural products. Our priority is investing in the study of SAC and advancing our knowledge of the link between calcium and overall health & wellness with the leader of the science & research community and medical experts. We are different because many supplement brands are white label or private label brands that drop ships their products and therefore does not absorb any research & development and facilities costs. Our compansy is GMP (Good Manufacturing Practice) certified in Canada which ensures the quality, consistency and integrity of our products and also the fair treatment of our employees.
