The science behind blood glucose control for weight loss 

Weight management is far more complex than how many calories we eat and how many the body uses. It has a lot to do with blood glucose levels! 

The role of blood sugar in the body

Blood glucose levels indicate the amount of sugar (glucose) in the blood. Typically, they are lowest in the morning and rise after a meal. When you eat carbs, sugar, and other starches, the digestive system breaks them down into simple sugars, which enter the blood. 

As blood glucose levels rise, the pancreas responds by producing insulin, a hormone that prompts cells to absorb blood glucose to use for energy immediately or store it for later. 

Insulin is the main player in fat storage

When you eat too many carbs, the elevated blood glucose levels send a signal to the pancreas there’s lots more sugar on the way. More insulin is produced, and sugars that aren’t used right away are stored for later use in the form of fat. 

Simply put, with elevated insulin levels, the body’s ability to burn fat for energy is impaired. The key to successful weight loss lies in keeping insulin spikes under control by balancing blood glucose levels.

The real reason behind cravings

High-carb meals cause blood sugar spikes. With that, more insulin is released, which causes a sudden drop in blood sugar levels, known as a ‘sugar crash’. This triggers cravings for sugary or carb-loaded foods and may lead to overeating. 

When your blood sugar levels are within a normal range, your body has a consistent source of energy. This prevents blood sugar spikes and crashes that trigger cravings. 

SlimBerine – the first step in weight loss 

Maintain blood glucose control for weight management

SlimBerine harnesses the power of berberine, a bioactive compound that has a long history in traditional Chinese and Ayurvedic medicine but has also gained attention in modern times. Berberine has been proven to improve blood glucose control, a key part of any successful slimming journey. 

We source the berberine from the Indian barberry, ensuring the preservation of its natural purity with a meticulous extraction process. On top of that, the capsules contain a high concentration of the active ingredient – one capsule equals 20,000 mg of Indian barberry powder. 

Our ultra-pure extract contains at least 97% pure berberine that is enriched with chromium and black pepper. This makes the formula an ideal solution for anyone searching for balanced blood glucose levels and sustainable weight management.

Premium natural-based ingredients 


What is berberine?

Berberine is a bioactive compound found in several plants. We source it from the Indian barberry (Berberis aristate), also known as ‘tree turmeric’. It’s traditionally used in Chinese and Ayurvedic medicine as it has many health benefits. 

How does SlimBerine work?

SlimBerine contains berberine and chromium for double blood sugar management. Berberine has been proven to improve blood glucose control, while chromium helps maintain normal blood glucose levels. 

Is SlimBerine effective for weight loss?

Blood glucose control for weight management is essential for two reasons. It regulates insulin, the hormone that signals cells to absorb and use or store sugar. Keeping insulin spikes under control allows the body to burn fat for energy. Optimal blood glucose levels can also prevent sugar crashes that cause cravings for sugary foods. 

How fast does SlimBerine work?

The speed and the amount of weight loss depends on every individual. We recommend using the product for at least 3 months for maximum efficiency. 

How long can I take SlimBerine?

For maximum efficiency, it is recommended that food supplements be used for 3 months, but it’s completely safe to use for longer. 

Can I take SlimBerine if I have diabetes or another medical condition?

Food supplements cannot replace prescription medication. If you are taking any medication or if you have any medical conditions, please consult your doctor before taking any food supplement. 

Can pregnant or breastfeeding women use SlimBerine?

This product is not recommended for pregnant and breastfeeding women.
