What is the main difference between Advanced Cellular Silver (ACS) 200 and “colloidal silver” products?

Advanced Cellular Silver 200 is a powerful and comprehensive antimicrobial going far beyond colloidal silver formulas in both antimicrobial and healing effect. Independent studies prove to ACS 200 Extra Strength to be far more effective in killing pathogens than Argentin, SilverMax, or any other brand of colloidal silver. ACS 200 Extra Strength is anti-viral, bactericidal, anti-fungal and anti-parasitic, killing Methicillin-resistant Staphylococcus aureus (MRSA), Candida and Rhinovirus at 99.99999% in less than 3 minutes. As performance benchmarks, these are extremely difficult pathogens to kill. Competing colloidal silver formulas have very mild antimicrobial effect when compared to ACS 200 Extra Strength.
ACS 200 Extra Strength is actively prescribed by health care practitioners in over 15 countries.

How do you determine the efficacy of ACS 200 Extra Strength?

The killing effect of any antimicrobial or antibiotic can only be determined by kill time studies. All kill time studies using ACS 200 Extra Strength have been performed using The Scientific Association Dedicated to Excellence in Analytical Methods (AOAC) standards at some of the top independent microbiological laboratories in the world.
Results RNA has sponsored over 500 kill time studies in the last 10 years alone.

How safe is ACS 200 Extra Strength?

As to the safety of ACS 200 Extra Strength in both short term and long term use, acute oral toxicity studies were performed with ACS 200 Extra Strength at a very high dose of 5,000 milligrams per kilogram of murine weight. At the end of the 14 day study, there was zero toxicity in any of the cells analyzed.

As to long term use, millions of doses of ACS 200 Extra Strength have been taken over many years by patients the world over delivering superb efficacy, without incident.

Does ACS 200 interrupt the floral balance in the intestine?

Sustained use of ACS 200 Extra Strength by many people over years of time has not shown any evidence of destroying the floral balance of the intestine.

Although the mechanism is not fully understood, what we do know is that pathogenic microorganisms are much more primitive in their cellular makeup than the bacteria comprising the healthy flora of the human body. The bacteria that make up healthy flora that interact with mammalian cells are much more sophisticated in their cellular makeup. As to claims by other silver manufacturers that silver can harm healthy flora, ACS 200 is uniquely different than any other silver product. After a 15 year history of selling ACS 200 to hundreds of thousands of customers, we know that ACS 200 does not harm the healthy flora, and in fact increases the health of the immune system as it very effectively resolves gut issues. As we know, antibiotics destroy healthy flora and thus, hurt the immune system.

What is the half life of ACS 200 Extra Strength?

Half life is the time it takes for the blood level to decrease by half after discontinuing product use. Therefore, if ingestion of ACS 200 Extra Strength (which has a half life of 15 days) is discontinued, and the blood level at the time is for discussion sake 20, in 15 days the blood level will decrease to 10.

What is the content of ACS 200

200 Parts Per Million (PPM) 99.99% pure silver colloid hydrosol

What silver particle sizes are provided in ACS 200 Extra Strength?

ACS 200 Extra Strength contains a very safe size range of pathogen lethal silver particles – from 0.4 microns down to nanometer. This range of sizes acts as broad arsenal in the pathogen attack.

In what sizes is ACS 200 Extra Strength currently offered?

ACS 200 Extra Strength is currently offered in 2 oz and 4 oz intra-oral sprays, 2 oz ACS Silver Gel topical treatment, 1 oz ACS Nasal Spray.

Is ACS 200 Extra Strength patented?

Yes. The silver technology of ACS 200 Extra Strength is backed by over 14 patents to date.

Will weather elements affect the product (heat or cold) if when delivered if customer cannot pick up immediately, sits at home or outside a Dr’s Office?

The only way the product would be affected is if it is cold enough to freeze the product (splitting the bottle) or hot enough to melt the bottle.

What is the shelf life of the Results RNA formulas?

Has an indefinite shelf life.

Do your formulas react to the plastic bottles?

The reason we use the very high grade High Density Polyethylene (HDPE) plastic is because of what you have already observed; both the ACS 200 Extra Strength PPM silver and the ACZ Nano Extra Strength zeolite products are very active to put it mildly. HDPE plastic is used for many packaging applications because it has excellent moisture barrier properties as well being lightweight and flexible. HDPE plastic has good resistance to chemicals, which is why it is commonly used to package many household and industrial cleaning products including detergents, bleaches, and even acids. HDPE is extremely resilient in this regard, (much more so than PET or other types of plastics, including glass) and therefore does not leech contaminants into the product.

What about side effects such as the possibility of permanent bluish discoloration of the skin?

As to long term use, millions of doses of ACS 200 Extra Strength have been taken over many years by patients the world over delivering superb efficacy, without incident. As a matter of medical silver use in history, there were over 5 million prescriptions of silver dispensed in the United States in 1929. Out of those 5 million users, there were less than 60 accounts of Argyria. None of those cases were associated with colloidal silver. These cases were associated with the use of silver nitrate.

What is the safety of ACS 200 Extra Strength for a woman who is trying to become pregnant or who is pregnant?

Robyn Arouty
I was prescribed the colloidal silver spray after several weeks of doxy for Lyme & I’ve had fantastic results!!!!*

Ed Womelsdorf
All of the above plus depersonalization acid reflux, IBS and light sensitivity. The price of these products is very reasonable considering what the average LLMD charges per visit plus the cost of Antibiotics. I had a positive experience with ACS 200. I would definitely recommend it… Pretty much in remission now.*

Xavier Keough
I’ve been using this for roughly 8 months and it has changed my life after suffering for 5 years and nearly dying. I never thought it would be as effective as antibiotics but it has been and then some…and without all the dangerous side effects. I’m grateful and pray it continues to work.*

Jorge L. Moreno
We have had great response to many different types of illnesses/infections using the ACS200 products!*

Rita Bradley Taylor Pettit
It really works. I will stay on a maintainable dose for the rest of my life. Thank you to all of the brilliant scientist who invented this pure form of silver. *

Bonnie McConnell
Best silver on the planet! Cured a brown recluse spider bite. Use it daily, got over a nasty bug in two days, while everyone else I know took weeks!

While I didn’t find specific studies to relate, there were consumer testimonials where silver was used for brown recluse bites. While not all recluse bites are necrotic, their hemotoxic venom can cause serious problems. I know having grown up in the South were these spiders are plentiful.

It makes sense, given that ACS 200’s broad spectrum antimicrobial and anti-inflammatory properties could prevent infection and exacerbation of symptoms. *

Moji Lavi-Khorramian
I am so thankful and beyond happy to have used this prouducts and can honestly say that has changed my life Thank you thank you thank you How lucky and blessed I feel to have found this . It’s worth every penny I rather not eat but use this no matter how little or limited I am financially. Thank you *

Nicole Pigeault
The BEST Silver Spray… I always have some in my house 🙂*

Steve Rey Sorensen
No other silver comes close to this, and that’s based off of my own personal experience, as well as some double blinded clinical and scientific studies i was fortunate enough to see for myself. Absolutely amazing product and would recommend it to anyone.*

Edna Smith
GOOD STUFF been using silver for years. put some in ear and throat a few days ago for what I thought may be start of a cold. cleared up in couple hrs.*

Jennifer L Giblin
Trust me it works!*

Yvonne Larsone
I don’t usually comment on products, but this is very important. Last year I was so listless, no energy, and I ached all over. Taking new meds one after another and finding no relief. Just wanted to sleep all day. I was familiar with this product but was not willing to try it. So I decided to throw away all 7 of the different medications and try this. What did I have to lose? A year later I have so much more energy that I have just finished a nurse traveling assignment in Alaska. At 69 going stronger than ever!! What have you got to lose? Try it.*

Bob Wade
I’ve been using ACS 200 for 2 years now. Nothing compares to it. Nothing.*
