Okay ladies,
I know I'm overloading you with articles, but this one is about how much chlorella can be taken. That's a question everyone has asked. I know babydollhair takes 3 gm and got excellent growth but surprisingly it's recommended to take even more. BUT if you read through the article it says NOT to take it all at once, to increase it slowly.

Chlorella
Disease-fighting dose: 10 grams / day
Maintenance dose: 5 grams / day
Upper limit:
there is no upper limit, but introduce chlorella into your diet gradually and monitor your stools. Since chlorella can result in mild diarrhea in some persons, introduce it slowly. (Your body will adapt over a period of a few weeks, allowing you to take more.)
Once again, most people take far too little of these foods. I've seen people take two tiny tablets of chlorella -- about 300mg -- and declare they've "taken my chlorella for the day!" That's like eating one bite of broccoli and expecting to receive the full health benefits of broccoli.
In order to be effective, you've got to take the much larger doses mentioned above. If you buy chlorella in tiny tablets, as it is often sold, that means taking a handful of tablets with each meal. Here's a tip: don't count out the tablets every single time. Count them once so you know what five grams looks like. After that, just grab a handful and toss it down your throat. It doesn't matter if it's off by a few tablets. Remember: these aren't drugs. You don't have to be exact about it, just make sure you're getting at least the doses mentioned above.
There's no harm in taking more, of course. Aside from the health benefits I've described here, the main thing you'll notice is that your stools will turn green. This is an indication that you're getting a good dose of chlorella into your diet.
If your stools aren't green, you aren't taking enough.
