Carb Blocker Ranking Factors

There are several factors that we used to rank and review these carb blocker supplements. We took into account the ingredients (whether they were natural, pure, or added), the proposed health benefits, their affordability, and their health and safety factors.

We ranked Utilize as the number one best carb blocker on our list due to its combination of affordability, overall nutrient content (vitamins and supplements), and its well-reviewed role as a carb catalyst and weight loss aid.

As we go down the list, we highlighted nine other ideal carb blocker supplements of varying prices and ingredients with different health benefits. All of these supplements aid the lowering of blood sugar and help to support better energy from carbohydrates, as opposed to carbs being stored for fat.

Ingredients and Dosages

Most of the above carb blocker supplements come with a recommended daily dose of 2-4 capsules per day. Generally, it’s suggested to take 1-2 capsules of a car blocker preceding each heavy-carbohydrate meal of the day.

However, if you take carb blockers for overall health supplement effects, you could also take them once in the morning and once in the evening.

Many carb blockers are rich in ingredients that support lowered blood sugar, such as chromium, cinnamon extract, and bitter melon extract. The supplements also commonly include popular vitamins, such as B complex vitamins, Vitamin C, and Vitamin D3.

In terms of allergen content, many of the carb blockers mentioned above are free of common allergens, such as tree nuts, gluten, shellfish, etc.

However, some of them are even vegan-, keto-, or vegetarian-friendly, including the capsules. This is why we particularly like Barberine-500, Glucose Optimizer, and Glycodrin.

Benefits

The benefits of the above ingredients range far and wide. Although carb blockers are mainly marketed towards athletes who want to lower blood sugar levels and/or bulk up, they have a lot of secondary health benefits to consider.

The main benefit of carb blockers is that they help with weight loss by stopping the digestion of carbohydrates. As a result, carbs get moved into energy, rather than fat buildup. But one of the other ways that carb blockers supposedly help with weight loss is by suppressing appetite. Some scientists even believe that carb blockers decrease hunger hormone levels (ghrelin levels), leading to eating less.

Another key benefit of carb blockers is that they may manage blood sugar well, which is helpful for more than just diabetics. Since they slow/stop carb digestion, they also lead to lower blood sugar levels when eating carbohydrates.

There are many side benefits of carb blockers, too, due to the fact that many of them contain vitamins and nutrients with specific health properties. For example, many carb blockers contain bitter melon extract.

The health benefits of bitter melon range from lowering blood sugar to providing Vitamin C ; A, as well as iron. Furthermore, many carb blockers contain different forms of Vitamin B and D, which have the beneficial property of improving mood and energy levels.

Price

In general, carb blockers can range in cost from about $15.00-$60.00 for a bottle of capsules. We factored this into our best carb blocker guide by identifying the carb blocker products that lied closer to the average cost for this type of supplement ($35.00-$40.00).

While some of the picks on our list entail costs closer to the higher end of prices, it’s due to their high quality compared to other options. In general, though, the top 10 list we’ve compiled represents mostly affordable options for those who want a decent carb blocker supplement.

Safety

Carb blockers are technically just supplements, meaning they aren’t an actual medication that needs to be prescribed by a doctor. That said, it’s always still advisable to consult with your doctor about using carb blockers before you try them. It’s important to note how carb blocker supplements and their specific added ingredients may affect your health and wellness.

The main reason it’s important to check with a doctor first is that many supplements are not required to be evaluated by the FDA. While prescription medications are much more heavily monitored and studied, most carb blockers claim to have health benefits that aren’t evaluated or proven.

Furthermore, the health benefits and safety of certain natural ingredients - like bitter melon extract, grape seed extract, and fenugreek - aren’t necessarily backed by hard science.

In many cultures, natural ingredients such as these are recommended for their use in alternative medicine, but there is a reason they aren’t the first choice to be prescribed by medical doctors.

That being said, carb blockers are generally very safe to take. Although you may experience side effects when taking them, such as GI issues, bloating, or gas, they’re often safe enough for adults, and non-pregnant or non-nursing individuals to use.

The only other individuals who should really have a concern about taking these are diabetics, who may need to change their insulin dose if they choose to take carb blockers.

Should You Use a Carb Blocker?

Many people debate whether or not it’s a good idea to take carb blockers, or if they’re even worth it. While they do seem to have palpable effects in terms of blood glucose and weight loss, they aren’t a surefire, quick fix for those who want to get lean.

When taking supplements like carb blockers, you run the risk of messing with your gastrointestinal health, which could become unsettled and lead to discomfort. You also run the risk of having to change your diet to make the carb blockers work (they work best in higher-carb diets).

If you do consult with your doctor and ultimately choose to use carb blockers as dietary supplements, it would be beneficial to work it into your health regimen.

As opposed to using it as a healthy lifestyle replacement, you should integrate carb blockers into a well-rounded lifestyle of ample exercise, healthy eating, water intake, good sleep, and other health measures.

At the end of the day, there is no instant way to lose weight. To do so in a healthy manner, you have to have patience and diligence.

Do Carb Blockers Work?

The supposed effectiveness of carb blockers is widely debated. Although there is some science and research to back up the use of carb blockers for weight loss, it also seems that they only get more effective if you eat more carbs than usual.

Essentially, you have to eat a carb-heavy diet in order to get a significant weight loss effect out of the carb blockers, which may be counterintuitive in some people’s weight loss journeys.

It’s also important to note that a carb blocker isn’t designed to block the digestion of all carbohydrates that you consume while taking it. Carb blockers only have an effect on certain types of carbohydrates (complex carbs), which usually don’t make up the entirety of a person’s diet.

This means that carb blockers only work to a certain extent, and you of course have to watch your diet and exercise routine if you really want to lose weight and lower your blood sugar spikes.

Whether or not a carb blocker will be effective also depends on which ingredients it contains. For example, if you have a carb blocker that only utilizes one or two ingredients that work to lower blood sugar, it’s not going to make a significant difference on your health.

Conversely, if you choose a carb blocker supplement that includes added ingredients such as cinnamon bark extract, berberine, and bitter melon extract, you might find that you have considerably more positive effects in terms of weight loss and lowering of your blood glucose levels. You can also look into adding a fat burner.

Are Carb Blockers Safe to Use?

Carb blockers are safe to use as long as your doctor approves them for you individually. In order to take them safely, you also need to stick to the suggested dosage for your chosen type of carb blocker and use them as directed.

Frequently Asked Questions

It may help you to know a tad bit more about carb blockers before you begin taking them as a supplement. Generally, people have concerns about carb blockers regarding how and when to take them, as well as their effects.

When should you take carb blockers?

Most carb blocker supplements are recommended as a pre-meal supplement. Generally, the bottles will tell users to take 1-2 carb blocker capsules/tablets just prior to eating the meal of the day with the largest quantity of carbohydrates.

However, you can also take these supplements as a twice daily option (in the morning and evening each day). Some carb blockers even start out as a higher/smaller dose, then change in the days following your first dose. Always read the facts on the bottle before beginning doses.

Which supplements work well in combination with carb blockers?

Many people who use carb blockers for weight loss also use them in combination with fat burning supplements. You can technically take these supplements in combination; however, it isn’t necessarily going to make a huge difference in terms of weight loss.

Fat burning supplements work similarly to carb blockers in that you have to consume a lot of fat in order for the supplement to have a significant effect. Therefore, it may be more helpful to just take the carb blockers on their own.

Do carb blockers eliminate the effect of carbohydrates?

No, while the name may be a bit misleading, carb blockers don’t actually get rid of carbohydrates or eliminate them from your system. Rather, they work to stop the digestion of carbs in the GI tract to prevent too many of them from getting stored as fat in the body. As a result, the carbs get stored for energy use instead, which is beneficial to athletes and muscle builders.

What is the difference between simple and complex carbohydrates?

As mentioned previously, carb blocker supplements target complex carbohydrates, rather than simple carbohydrates. Simple carbohydrates are those that you’ll find in processed food like soda, sweets, and juice. Simple carbohydrates chain together to form complex carbohydrates.

On the other hand, complex carbohydrates are those that you’ll find in fibrous foods such as grains, legumes, pastas, and bread. Thus, if you want your carb blocker to be effective, you need to eat foods with complex carbs.

How do carb blockers work on a scientific level?

Carb blockers stop or slow the digestion of complex carbs by preventing enzymes in your digestive tract from breaking down ingested carbohydrates. The result is that carbs pass through your intestines without adding calories or increasing your blood sugar levels so much.

Conclusion

We hope you found our guide to the top 10 best carb blockers of 2022 to be useful. Carb blockers are supplements used to stop the digestion of complex carbohydrates, which may aid in weight loss and the process of lowering blood sugar spikes.

There are other benefits to these supplements, which come from their added ingredients, such as vitamins and other nutrients.

While carb blockers are safe to use, you should always consult with a doctor before beginning to use any over the counter supplements, especially if you are diabetic.

They have numerous benefits, from heart health to weight loss, hunger decrease, lower cholesterol levels, and more.
