How Does BerbeThin Work?

BerbeThin works by naturally mimicking the same chemical reactions that happen inside your body when you lift weights, spin or sweat bullets on the treadmill.

Is BerbeThin Like Those Over-The-Counter Fat Loss Supplements?

Absolutely not. There’s no caffeine, no sugar, no jitters or agitation.

How Many Bottles Should I Order?

I suggest 3 bottles at this discounted, first-time customer pricing. However, if you have a family, or simply want to stock up at my lower price, I'd advise you to purchase the six-bottle option to take advantage a the preferable price discount.

How Often Do You Suggest I Take BerbeThin?

One capsule three times daily, in the morning before breakfast, and evening is a highly effective dose for my typical patients.

Is BerbeThin Safe?

Yes. Both the formula itself, and the capsules, are made from 100% non-GMO, plant based ingredients, which are independently tested for purity and quality.

Can I take BerbeThin With My Other Supplements?

Absolutely. I encourage many of my patients to include a daily multivitamin, probiotic, and Omega supplements as part of their overall wellness programs. That said, I encourage you to speak with your doctor when you begin to take new supplements.

When Can I Expect Results?

Keep an eye on your scales. Most patients report dropping pounds of fat over the course of 2-4 weeks. The best results are achieved by patients who regularly take BerbeThin for more than 4 weeks. Please use as directed.
