What are Clif Bloks Energy Chews?

Clif Bloks Energy Chews are small, bite-sized cubes designed to deliver quick, sustained energy for endurance athletes. They provide a solid, chewable option that’s easy to control. No messy packets, no sticky hands, and no chugging liquid mid-run.

Each serving (three chews) contains fast-acting carbohydrates that help maintain your energy levels, plus electrolytes to replace what you lose through sweat. Some flavors also include caffeine for an extra boost, making them a go-to for long-distance runners, cyclists, and high-intensity athletes.

Compared to traditional Clif Shot Bloks, which are more gel-like, Clif Bloks have a firmer texture and come in pre-portioned packs, allowing athletes to fuel up gradually instead of all at once. They’re lightweight and easy to carry. Plus, they dissolve quickly—ideal for anyone who needs sustained energy.

The science behind the chews 

Clif Bloks Energy Chews are designed with fast-absorbing carbohydrates, giving your muscles the fuel they need without the sluggish digestion of solid foods. Each chew contains simple sugars like organic tapioca syrup and organic cane sugar. These are rapidly converted into glucose, keeping energy levels steady during endurance activities.

Beyond carbs, electrolytes (like sodium and potassium) help replace what’s lost through sweat, supporting hydration and muscle function. Some Clif Bloks mixed flavors also contain caffeine (50mg per serving) for a mental and physical boost. These are particularly beneficial for for long races, early-morning training, or times when fatigue sets in.

Compared to sports drinks, Clif Bloks allow for more controlled intake—athletes can eat one or two at a time instead of gulping down a full bottle. Unlike energy gels, which you tend to swallow all at once, Bloks are bite-sized and easy to pace, preventing sugar crashes or stomach discomfort.

For those looking to try a range of flavors, Clif Bloks Variety Packs make it easy to test different options and find what works best for training and recovery.

Clif Bloks Energy Chews reviews—what athletes are saying

Athletes consistently turn to Clif Bloks Energy Chews for their convenience, taste, and steady energy boost. Most agree that these chews offer an easy, mess-free way to fuel up mid-workout.

A reviewer from Cycling Independent noted,"Clif Bloks are sweet but not too sweet. They chew and swallow easily when I'm tired." Many athletes appreciate that they don’t leave a sticky aftertaste and can be eaten gradually, making them easier to digest than gels. Those who opt for the Clif Bloks Variety Pack enjoy switching between flavors like Margarita (which has extra sodium for hydration) and Black Cherry (which includes caffeine for a mid-race boost).

Some users mention that the chews can soften in hot weather, so keeping them in a cool spot while training is recommended. Others on Reddit’s running community highlighted that Clif Bloks mixed flavors are a great way to keep things interesting during long runs, with one user noting “my favorites are strawberry, mountain berry, and watermelon”.

Overall, reviews show that Clif Bloks deliver long-lasting energy and taste great. They’re a flexible fueling option—whether you're training for a marathon, heading out on a long bike ride, or perhaps looking ahead to an intense pickleball match.

Clif Bloks side effects

While Clif Bloks Energy Chews are a favorite among athletes, it’s important to be mindful of a few potential side effects. Since each serving contains sugar for quick energy, consuming too many chews at once could lead to a temporary sugar spike. This is why it’s best to pace yourself and space out the chews throughout your workout, rather than taking them all at once.

Some flavors include caffeine, which can provide a helpful boost but may not suit everyone. If you’re sensitive to caffeine, opt for non-caffeinated flavors or mix them within your routine. Staying hydrated is also key, as this helps with both energy absorption and reducing any digestion issues that could arise from taking in concentrated carbs.

Digestive sensitivity varies from person to person, so it’s helpful to test Clif Shot Bloks during a less intense session. This will help determine how they work for you. Overall, paying attention to Clif Bloks side effects is simple: balance intake, stay hydrated, and most importantly, listen to your body.

Where to buy Clif Bloks at the best value

Finding where to buy energy chews at the best price can take some searching, but there are a few ways to save. While many sporting goods stores and bike shops carry them, availability can be hit or miss.
