CDS vs MMS: Key Differences and Which One Is Right for You
You already know both release chlorine dioxide. The real question is which one matches how you actually plan to use it day to day.
Pick Based on Your Daily Setup
Look at how much time and equipment you have on hand.
| Your situation | Start with | Why |
|---|---|---|
| Mixing at home is fine and you want lowest cost per dose | MMS | Uses basic sodium chlorite plus activator you already keep |
| You travel or need something ready in seconds | CDS | Comes pre-activated in a sealed bottle |
| You prefer fewer taste variables each time | CDS | Single liquid, consistent strength |
| You make larger batches for family use | MMS | Easy to scale the same activator ratio |
How to Prepare Each One
MMS needs two steps every time.
- Measure drops of sodium chlorite solution into a dry glass.
- Add the same number of activator drops, wait 30 seconds until it turns amber, then dilute in water.
CDS skips the activator step.
- Pour the pre-made solution straight from the bottle.
- Dilute in water at the ratio you need.
Real Dosing Examples
A person starting at three drops three times a day usually does this with MMS: 3 drops sodium chlorite plus 3 drops 4% HCl, wait, add to 200 ml water. Same person using CDS measures 3 ml of 3000 ppm solution into the same 200 ml water. Both reach roughly the same chlorine dioxide output, but only one requires the wait and extra bottle.
- Protocol 1000 style: split into 8-10 small doses across the day.
- External spray: CDS works straight from the dropper bottle into a spray bottle; MMS needs fresh mixing each time.
Storage and Shelf Life Notes
Keep both out of direct sun. MMS sodium chlorite lasts years in a cool cabinet. Once you add activator it only stays potent for a few hours. CDS holds its strength for months in the original dark bottle if the cap stays tight. Check the date on any bottle you buy and write the opening date on the label so you know when to replace it.
