Data-driven optimizers seeing measurable improvements
I have been using Levels for 6 months, and SugR-2-FibR made a noticeable difference in my post-breakfast spikes. Went from averaging 155 mg/dL peaks to around 125 mg/dL. The data does not lie.
— Sarah M., Levels User
As someone who tracks everything on my Dexcom, I appreciate supplements that actually show up in my data. SugR-2-FibR helps me maintain metabolic flexibility without cutting out foods I enjoy.
— Jessica L., Dexcom User

Everything you need to know about SugR-2-FibR
Most users notice smoother post-meal glucose curves within 3–7 days of consistent use. Because SugR-2-FibR works by converting digestible sugars into beneficial fiber before they're absorbed, the effect is often visible on your Dexcom, Levels, or Stelo device fairly quickly when taken before meals.
Take 1 serving before meals that contain carbohydrates. It works best when taken shortly before eating so the enzyme can begin converting sugars as you digest your meal. Many users take it with breakfast, lunch, and dinner for full-day coverage.
Yes. SugR-2-FibR uses a patented enzyme blend designed for regular use. It is Non-GMO, vegan, and NSF-certified. As with any supplement, we recommend consulting your healthcare provider if you have specific medical conditions or take prescription medications.
Absolutely. While the product is especially popular with CGM users who want to see the difference in their data, many people use it simply to support more stable energy and metabolic flexibility without needing to restrict carbs.
SugR-2-FibR is tasteless and dissolves easily, so it won't affect the flavor of your meals. Most users report no noticeable side effects. As with any fiber-related product, some people may experience mild digestive adjustment in the first few days.
Subscribe & Save gives you 20% off every order plus free shipping and lets you pause or cancel anytime. It's the best value if you plan to use SugR-2-FibR regularly. One-time purchase has no commitment.
We offer a 30-day CGM Results Guarantee. Use SugR-2-FibR consistently before meals for 30 days. If you don't see measurable improvement in your post-meal glucose spikes on your CGM, contact us for a full refund.
SugR-2-FibR is generally well-tolerated alongside most other supplements. However, because it affects carbohydrate absorption, we recommend speaking with your doctor or pharmacist if you take medications that influence blood sugar.
