Is 5-hour Energy Safe for People with Diabetes?
Evaluating the safety, ingredients, and health effects of 5-hour Energy and similar energy drinks for people with diabetes.
Many energy drinks like 5-hour Energy promise a quick boost in alertness, but for people living with diabetes, knowing what’s truly safe can be challenging. This article provides a comprehensive examination of 5-hour Energy’s ingredients, the risks and benefits for people with diabetes, and evidence-based guidance for making informed choices about energy drinks.
Understanding Energy Drinks and Diabetes
Energy drinks are popular for their ability to enhance mental focus and reduce fatigue, but concerns remain about their effects on blood sugar and overall metabolic health. People with diabetes must pay special attention to the ingredients in these beverages, especially added sugars, artificial sweeteners, and caffeine content, all of which may affect blood glucose control and cardiovascular health.
What Is 5-hour Energy?
5-hour Energy is a widely recognized energy drink available in small 2-ounce bottles. It is marketed as a dietary supplement rather than a conventional beverage and promises a fast, sustained energy boost without sugar or many calories.
- Format: 2-ounce (60 ml) energy shot, typically containing no sugar and around 4 calories per serving.
- Key Ingredients: caffeine, B vitamins (notably B6, B12), taurine, glucuronolactone, citicoline, and non-nutritive sweeteners such as sucralose or acesulfame potassium.
5-hour Energy’s zero-sugar formulation often makes it appear preferable for glucose management compared with other high-sugar energy drinks; however, the drink’s high caffeine and additive content warrant caution.
Key Ingredients in 5-hour Energy and Their Health Effects
| Ingredient | Purpose | Potential Concerns |
|---|---|---|
| Caffeine (~200 mg) | Central nervous system stimulant; increases alertness | Can raise blood sugar, blood pressure, and heart rate May impair insulin sensitivity |
| B Vitamins | Support energy metabolism | Generally safe; excess excreted in urine |
| Taurine, Glucuronolactone | May help with focus and energy, mechanism not fully established | Limited safety data at high supplement doses |
| Non-nutritive Sweeteners (e.g., sucralose, acesulfame K) | Provide sweetness without sugar/calories | May affect gut bacteria and glucose tolerance in some individuals |
Caffeine Content
Each 5-hour Energy shot contains approximately 200 mg of caffeine—equivalent to two strong cups of coffee. While caffeine can temporarily increase mental alertness, it also stimulates the release of stored glucose from the liver, which may result in noticeable blood sugar spikes for some people with diabetes. High caffeine intake can also acutely decrease insulin sensitivity, which complicates blood glucose management.

Sugar and Sweeteners
Unlike standard energy drinks, 5-hour Energy is sugar-free but instead uses artificial or non-nutritive sweeteners. While these sweeteners avoid immediate blood glucose spikes, emerging evidence suggests that regular consumption may still influence glucose metabolism and gut health in ways that are not yet fully understood. Individual responses vary, and people with diabetes should be mindful of the potential subtle effects of artificial sweeteners over time.
Risks of Energy Drinks for People with Diabetes
Energy drinks, including 5-hour Energy, can pose several risks for individuals with diabetes due to their ingredient profiles and high caffeine content. Here’s a breakdown of key concerns:
- Blood Sugar Fluctuations: High caffeine intake increases liver glucose release and can cause blood sugar to rise, followed by potential crashes that may stimulate hunger and overeating.
- Impaired Insulin Sensitivity: Caffeine reduces insulin sensitivity on an acute basis, potentially leading to higher post-meal blood glucose readings.
- Cardiovascular Effects: Caffeine and sodium in energy drinks may raise blood pressure and heart rate, increasing the risk of heart attacks or strokes in people with diabetes, who already face elevated cardiovascular risks.
- Weight Gain: While 5-hour Energy is low in calories, other energy drinks with high sugar content can contribute to excess caloric intake and weight gain, leading to worsened insulin resistance and diabetes management challenges.
- Adverse Reactions: Reported side effects include jitters, anxiety, insomnia, headaches, gastrointestinal upset, and—in rare cases—cardiac events.
Comparing 5-hour Energy to Other Energy Drinks
| Beverage | Serving Size | Sugar (g) | Caffeine (mg) | Calories |
|---|---|---|---|---|
| 5-hour Energy | 2 oz | 0 | 200 | 4 |
| Red Bull | 8.4 oz | 27 | 80 | 110 |
| Monster | 16 oz | 54 | 160 | 230 |
| Rockstar | 16 oz | 24 | 160 | 122 |
Key Insights: The absence of sugar in 5-hour Energy eliminates the most significant source of blood sugar spikes seen in conventional energy drinks. However, the high caffeine load remains concerning for individuals who already struggle with glycemic variability or cardiovascular issues.
Side Effects and Potential Health Risks
Energy drinks have been linked with emergency room visits, particularly among young people or those with pre-existing health conditions. Reported side effects include:
- Rapid heart rate
- Increased blood pressure
- Headaches and migraines
- Jitters and anxiety
- Sleep disruption or insomnia
- Gastrointestinal distress
- Rarely: cardiac arrhythmias and liver injury at very high intakes
The U.S. Food and Drug Administration (FDA) has documented adverse event reports associated with 5-hour Energy and other similar drinks, though definitive links to serious harm are uncommon in moderate consumers.
Potential Benefits of 5-hour Energy for People with Diabetes
There are limited—but relevant—scenarios where 5-hour Energy may be preferable to higher-calorie options:
- No Sugar: People seeking a sugar-free way of increasing alertness may opt for 5-hour Energy, as it won’t cause the sudden blood glucose spikes that sugar-sweetened beverages do.
- Low Calories: With only a few calories per serving, it won’t appreciably impact weight for most people if consumed occasionally and in moderation.
- Convenience: For those who tolerate caffeine well, 5-hour Energy’s small size and portability may be a practical substitute for coffee when on the go.
Despite these points, the benefits do not eliminate the importance of careful monitoring and moderation for those with diabetes.
Who Should Avoid 5-hour Energy?
Certain individuals should exercise particular caution or avoid energy drinks entirely:
- People with a history of high blood pressure or cardiovascular disease
- Individuals with poor blood glucose control or frequent hypoglycemic/hyperglycemic events
- Children, teenagers, and pregnant or breastfeeding women
- Individuals sensitive to caffeine, or with a known history of anxiety, insomnia, or gastrointestinal issues
Practical Tips for People with Diabetes Who Consider Energy Drinks
- Read labels carefully: Check for sugar, caffeine, and sodium content
- Track your blood sugar: Monitor before and after consuming any energy drink to understand your individual response
- Limit portion size: Stick to a single serving and avoid combining with other sources of caffeine
- Stay hydrated: Prioritize water over energy drinks to maintain healthy blood glucose and circulation, especially during exercise or hot weather
- Consult your healthcare team: Discuss any concerns and your overall caffeine tolerance to avoid adverse effects
Healthier Alternatives to Energy Drinks for Sustained Energy
Many people consume energy drinks out of habit or convenience, but better choices can often deliver energy without unwanted health risks. Consider the following options:
