How to Take DiBerberine 300x Enteric Dihydroberberine
To achieve the maximum bioavailability and cellular energy support via AMPK activation of DiBerberine 300x, strict adherence to proper dosing guidelines is required. Because this product relies on advanced enteric coating and P-gp modulation, how you take the capsule is just as critical as the ingredients inside it.
Standard Dosing Instructions
- Serving Size: 1 enteric capsule per day
- Servings per Bottle: 30 (Providing a full 30-day supply)

Critical Rule: Do Not Open, Crush, or Chew the Capsule
The acid-resistant vegetable capsule used in DiBerberine 300x is not a matter of packaging preference, it is the absolute functional mechanism of the product. If the enteric capsule is broken, crushed, chewed, or opened in any way:
- The highly sensitive DHB is immediately exposed to the harsh stomach acid.
- The stomach acid (pH 1-3) triggers a rapid oxidation reaction, forcefully converting the DHB straight back into regular berberine HCl.
- The entire massive 6.7x absorption advantage of DHB is entirely eliminated before it reaches your intestines.
You must swallow the capsule whole with a full glass of water.
With or Without Food?
For optimal results, we highly advise taking your daily capsule with your largest meal of the day. More importantly, however, is consistency. Consistency matters far more than the exact size of the meal. Take it consistently at the same time every single day.
When to Expect Results
AMPK activation and cellular energy pathways take time to adapt. Effects on energy metabolism and AMPK activation typically begin to appear at 6-8 weeks of consistent daily use. You should expect the most significant observations in the 6-12 week window. Remember, this is about cellular AMPK activation, not a quick stimulant flush.
Drug Interactions: Talk to Your Healthcare Provider First
DO NOT TAKE THIS PRODUCT WITH MEDS. Berberine and DHB can interact with certain medications via CYP3A4 pathways and RGBooster1 can increase absorption of many medications. You must consult your healthcare provider if you are taking any medications and suggest not taking medications within 4-5 hours after taking this product after talking to your doctor, also be aware of the following:
- Blood thinners (warfarin): Berberine affects CYP3A4 metabolism.
- Statins (atorvastatin, simvastatin, lovastatin): Berberine strongly inhibits CYP3A4, the primary metabolic pathway for statins. Combined use may dangerously increase statin plasma levels.
- Any CYP3A4-metabolized medications.
Storage Requirements
The acid-resistant vegetable capsule is sensitive to extreme environments. Store your bottle in a cool, dry place entirely away from direct sunlight. Do not store your supplements in the bathroom, as the severe heat and ambient humidity from showers can physically degrade the enteric coating over time, ruining the capsule's protection mechanism.
Secure Your 30-Day Supply of DiBerberine 300xFrequently Asked Questions
How long does DiBerberine 300x take to work?
DHB/berberine activates AMPK through enzymatic pathways, not stimulant mechanisms. Users in berberine clinical literature consistently report effects on energy metabolism and AMPK activation beginning to appear at the 6-8 weeks mark with consistent daily use. The most significant observations typically occur in the 6-12 week window. Consistency matters, daily use is required for cumulative AMPK activation benefits.
What is enteric-coated dihydroberberine?
Enteric-coated dihydroberberine is DHB in an acid-resistant capsule that bypasses the stomach and dissolves only in the small intestine. Without enteric coating, stomach acid converts DHB to regular berberine before absorption. DiBerberine 300x by RevGenetics uses an acid-proof enteric capsule and adds RGBooster1, a patent-pending P-glycoprotein efflux modulator, to address the second absorption barrier.
Will enteric-coated DHB cause stomach issues like regular berberine?
For most people, no. Berberine GI side effects occur because most of a high-dose standard berberine protocol is never absorbed, remaining in the gut lumen and disrupting motility. DiBerberine 300x uses an enteric capsule that bypasses the stomach entirely, and a 2022 study found 100mg DHB produced approximately 6.7x greater plasma berberine exposure than 500mg standard berberine HCl (from one-fifth the dose).
Why do most dihydroberberine supplements underperform?
Most DHB supplements use standard capsules that dissolve in stomach acid (pH 1-3), converting dihydroberberine back to regular berberine before reaching the small intestine. This eliminates DHB's absorption advantage. P-glycoprotein efflux pumps at the intestinal wall further reduce absorption. DiBerberine 300x addresses both barriers.
Who makes DiBerberine 300x?
DiBerberine 300x is manufactured by RevGenetics, founded by Anthony Loera and based in Miami, FL. It is produced in a USA-based cGMP-certified facility and independently third-party tested for purity and potency. The RGBooster1 formulation is covered by a patent application filed with the USPTO.
