Jump Ahead to the Best Carb Blockers

Carbohydrates are one of the three macronutrients that are necessary for your body. They are starches, sugars, and fibers that are packed with energy. They are in fruits, vegetables, grains, and even in milk, which means they are in a wide variety of food. Their widespread availability makes them hard to avoid.

What Are Carb Blocking Supplements?

Carb blocking supplements block the absorption of certain carbohydrates, which reduces your caloric intake and lowers your blood sugar. They do this by inhibiting some of the enzymes that break down certain carbohydrates and starches. The common ingredients that are utilized in carb blockers include white kidney bean extract, garcinia cambogia, or a product called Phase 2.

The enzyme they inhibit is called amylase, which is made in the pancreas and the salivary glands. Garcinia cambogia is an exception, because it inhibits the enzyme citrate lyase. Top carb blockers block between 50% to 65% of the amylase that is supposed to break down these carbs, which means that not all ingested carbohydrates are blocked from being absorbed. This is good, because we do need carbs, just not as much of them sometimes.

Supplemental carb blockers are non-prescription, and you can by them over the counter. They use the same methods as prescription carb blockers. Some prescription carb blockers that are available are used for controlling blood sugar levels in patients that have type II diabetes. By reducing some of the carbs you absorb, the best carb blocking supplements are beneficial for weight loss.

Benefits of Carb Blockers

Carb blockers are helpful supplements to aid in weight loss. Paired with exercise and a healthy diet, carb blockers can improve your weight loss results. This means it speeds up the process of achieving your goal weight! It is also beneficial for getting past the most difficult weight to lose. The most difficult weight to shed is often the last you have to lose.

With that said, even the most effective carb blocking supplements are no magic pills. They are no fix for an unhealthy diet, although they can help slightly. For the best results, these products should be used in combination with a balanced diet and exercise plan.

Who May Benefit from a Carb Blocker?

Carb blocking supplements are great options for things like weight management, improving athleticism, improving blood sugar levels, and so on and so forth. Certain people who have specific health goals can really benefit from taking a carb blocker.

  • Those trying to lose weight – These are the people who can benefit the most from carb blockers. Carb blockers have numerous weight loss benefits, including blocking the absorption of carbohydrates, reducing appetite, promoting feelings of fullness, reducing caloric intake, reducing fat storage, and improving energy levels.
  • Those with high carbohydrate diets – Carb blockers have been shown to be the most beneficial to people who have high carb diets. This is because they reduce a certain percentage of the calories you absorb from carbohydrates only, and if you eat a lot of carbohydrates, carb blockers will make a bigger difference metabolically. If you have a high carbohydrate diet, carb blockers can help to fight weight gain from the carbs you consume.
  • Those who are athletes – Athletes can benefit from carb blockers in a couple of ways. Because carb blockers are effective weight loss supplements, they can help athletes reach a goal weight or body fat percentage in a shorter period of time. Some types of athletes that may gain the most benefit from this would be bodybuilders, wrestlers, and runners, among others. They can also benefit from the increase in athletic endurance. Those who participate in long workouts or enduranced based sports can potentially improve their performance through the use of carb blockers.

Many different types of people can benefit from carb blockers. Over 50% of Americans are at or above the recommended intake of carbohydrates as of 2015. The best carb blockers can help you to reduce your carbohydrate intake if you are above the limit or reduce your carbohydrate intake so that you may lose weight

How to Take Carb Blockers

Because the purpose of top carb blockers is to reduce the absorption of carbs, carb blocker supplements should be taken with a meal, ideally within 10 minutes before the food is consumed. Some products have instructions that differ, so make sure to read the directions supplied by the product. Generally, two to three doses are taken per day. Be sure to closely follow dosage instructions, and do not take more than the recommended amount.

Side Effects of Carb Blockers

Carb blockers cause undigested carbohydrates to pass through the digestive tract, resulting in the fermentation of carbs. This can cause side effects such as gas, bloating, and abdominal pain. If you have diabetes and take insulin, carb blockers may cause low blood sugar, so be sure to talk to your doctor before taking these products.

What to Look for in a Good Carb Blocker

A good carb blocking supplement can be identified by analyzing a couple of characteristics. One of the most important characteristics of a good carb blocker is the use of quality and effective ingredients at an effective dose. There are a couple ingredients that are used most commonly in carb blockers. These include:

  • White kidney bean extract – White kidney bean extract is a substance known as phaseolamin that is found in white kidney beans and blocks amylase. By blocking alpha-amylase, less carbohydrate molecules are broken down into simple sugars. This means that less calories are absorbed and less sugar enters the bloodstream, which results in reduced body fat production. An effective dosage is between 500 and 3,000 mg per meal.
  • Garcinia cambogia Garcinia cambogia is a tree that grows in Southeast Asia and India, and produces a fruit with a rind that contains hydroxycitric acid. Hydroxycitric acid, also known as HCA, can prevent fat storage, increase endurance, and help control appetite. HCA does this by blocking the enzyme citrate lyase, reducing appetite, promoting satiety, and speeding the metabolism. It also reduces the amount of carbohydrates that are turned into body fat by disrupting this very process, which is called fatty acid biosynthesis. An effective dosage of garcinia cambogia is 500 to 1,000 mg taken per meal.
  • Phase 2 – Phase 2 is a proprietary ingredient used in carb blockers that is all natural. It includes non-stimulant white kidney bean extract. Phase 2 has been clinically proven to reduce the digestion and absorption of dietary starches by up to 66%. An effective doses of Phase 2 are 500 to 1,500 mg per meal.

Another aspect of a good carb blocking supplement that should be analyzed is the company that produced the product. A top carb blocking supplement will be produced by a reputable company. Researching a little bit about the manufacturer can help you get a sense for their reputation. Our list of top 10 carb blocking supplements does the research for your convenience.

Lastly, evaluating the price of the supplement compared to its value is important. Get a feel for the market price ranges for the supplement and find out if it is fairly priced for the amount it offers, and the ingredients of the supplement. If a supplement is priced higher than some alternatives, it will be noted on our list.
