Product Overview


  • Phase 2 Carb Controller
  • Dietary Supplement

Source Naturals Carbohydrate Blocker contains Phase 2 white kidney bean extract. Phase 2 works by slowing down the digestion of starch by inhibiting alpha-amylase, an enzyme that breaks down starch to be more fully absorbed by the body. Carbohydrate Blocker may help support weight loss when used in conjunction with the Maximum Metabolism Weight Loss Plan (included).

Suggested Use

2 tablets with a glass of water (8 ounces), 5 to 10 minutes before a meal containing starch. If Carbohydrate Blocker is taken too early, it can pass through the body before interacting with food. Do not exceed 6 tablets per day.

Other Ingredients

Microcrystalline cellulose, stearic acid, and modified cellulose gum.


Store in a cool, dry place.

Caution: May cause more frequent bowel movements, and stomach upset. If you have diabetes, consult your physician before using this product. Do not use if you are pregnant, may become pregnant, or breastfeeding.

Do not use if either tamper-evident seal is broken or missing. Keep out of the reach of children.

Time will tell

Only recently started using them so I am not sure how well this works but so far so good.

Thanks for your feedback!

Many uses...

Not only does the Source Naturals Phase 3 Carbohydrate Blocker help with some weight loss, but most importantly for me is that it helps keep my blood sugar in check it i over do it on my carbs. Another great benefit is that it helps keep you "regular" by having more bowel movements. They are not crampy or diarrhea type bm's they are just more often. Which definitely helps of course to remove toxins from your body..

Thanks for your feedback!

Phase 2 Carb Blocker

I feel like I can tell this works when I take it about 30 min before a meal. The hard part is remembering to do it. It may make you have gas though but that's how I know it's helping me eat less carbs b/c I don't like the side effect so now I'm more aware of what I eat.

Thanks for your feedback!
