What is C3G — And Why Health Experts Are Obsessed With It in 2025

If you haven’t heard of C3G (cyanidin-3-glucoside), you’re not alone—but it's time to get familiar. This naturally occurring compound is rapidly gaining attention in health, fitness, and nutrition circles for its wide-reaching effects on metabolic health, weight management, inflammation, and cellular protection.

So, what is it?

C3G is a type of anthocyanin, a powerful class of flavonoids responsible for the dark red, purple, and blue pigments in plants. While you can find small amounts of C3G in foods like black rice and purple corn, haskap berries contain one of the highest concentrations—making up to 80% of their anthocyanin content.

That makes haskap juice and powder one of the most potent sources of C3G on the market.

Here are 7 science-backed reasons to add C3G to your daily wellness routine—especially through haskap-based products.

1. C3G Supports Glucose Regulation & Insulin Sensitivity

Maintaining stable blood sugar and insulin response is key to reducing the risk of type 2 diabetes and metabolic disorders.

A 2023 study in Frontiers in Endocrinology confirmed that C3G improves insulin sensitivity and enhances glucose uptake by activating AMPK pathways and modulating gut hormones like GLP-1.

This means C3G may:

• Improve your fasting blood glucose

• Reduce insulin resistance

• Support overall metabolic flexibility

2. C3G May Help Prevent Fatty Liver Disease (NAFLD)

Non-alcoholic fatty liver disease (NAFLD) now affects nearly 1 in 3 adults globally—and early prevention is critical.

Research in Nutrients (2023) shows that C3G supplementation significantly reduced hepatic fat accumulation and improved liver enzyme profiles in animal models. These results suggest that C3G may be a safe, natural aid in managing early stages of fatty liver disease.

Pairing haskap powder with a balanced diet may offer a natural line of defense for your liver.

3. C3G May Reduce Weight Gain and Improve Fat Metabolism

Obesity-related inflammation and metabolic syndrome are two of the most widespread health issues today.

Multiple studies—including a 2022 study published in Journal of Functional Foods—report that C3G:

• Reduces fat mass accumulation in high-fat diet-fed models

• Modulates adipokine signaling

• Improves lipid metabolism and energy expenditure

Though many results are from preclinical studies, the consistency across studies is pushing clinical trials forward, including trials underway in Europe and Japan.

4. C3G Shows Promise in Cancer Research

Let’s be clear—no natural compound should be viewed as a cancer cure. However, C3G is showing compelling potential in research aimed at cancer prevention and adjunct support.

In a 2023 study from the World Journal of Surgical Oncology, C3G was shown to inhibit the proliferation of lung adenocarcinoma cells through oxidative stress modulation and apoptosis signaling.

Other ongoing research is exploring C3G’s role in:

• Breast and colon cancer models

• Limiting angiogenesis (blood vessel growth that feeds tumors)

• Enhancing chemo-sensitivity in some cancer treatments

Further human studies are needed—but the anti-mutagenic and protective properties of C3G are firmly established.

5. C3G May Enhance Learning and Memory

Neuroinflammation and poor diet are closely linked to cognitive decline. Fortunately, C3G appears to cross the blood-brain barrier, offering direct benefits to brain health.

Recent research published in Brain, Behavior, and Immunity (2024) shows that C3G supplementation:

• Improved short-term memory and learning

• Enhanced neuronal plasticity

• Reduced markers of brain inflammation in aging models

In human studies, diets rich in anthocyanins—including C3G—are correlated with slower cognitive decline and reduced dementia risk over time.

6. C3G Protects Pancreatic Beta Cells

Your pancreatic beta cells are responsible for producing insulin. Damage to these cells—often caused by oxidative stress—can lead to type 2 diabetes or dependence on insulin therapy.

Studies in Oxidative Medicine and Cellular Longevity (2023) demonstrate that C3G:

• Reduces oxidative stress in pancreatic tissue

• Preserves insulin secretion function

• Modulates pathways that protect against cellular apoptosis

This research reinforces the protective role that antioxidant-rich foods like haskap play in long-term metabolic health.

7. C3G Has Strong Anti-Inflammatory Effects

Inflammation is often called the “root of all chronic disease.” Whether it's arthritis, gut issues, or autoimmune flare-ups, C3G’s anti-inflammatory actions are wide-reaching.

A 2024 paper in International Journal of Molecular Sciences found that C3G:

• Suppresses key inflammatory cytokines like TNF-α and IL-6

• Modulates the gut–brain–immune axis

• Promotes intestinal cell barrier integrity, crucial for gut health

Haskap’s high concentration of C3G makes it especially beneficial for individuals dealing with chronic or systemic inflammation.

In Summary: Why Add C3G (via Haskap) to Your Daily Diet?

From blood sugar control to brain function, fat metabolism to inflammation, C3G is proving to be one of nature’s most powerful health allies. And haskap berries offer one of the most bioavailable, natural sources of this compound.

Here’s how to easily incorporate C3G into your daily routine:

• Haskap Juice: 1 oz daily as a morning wellness shot

• Haskap Berry Skin Powder: 1 tsp in smoothies, yogurt, oatmeal, or water

• Haskap Concentrate: Add to baking, sauces, or even tea

Backed by a growing body of 2025 research, C3G via haskap is a smart addition to almost any diet—whether your goals are performance, prevention, or long-term vitality.
