How to find the best carb blockers and why are they so popular? Many people struggle to lose weight and keeping up with a restrict diet.
If you are looking for an effective way to lose weight without starving yourself, consider carb blocker supplements (also known as starch blockers).

Complex carbs can be found in many foods, such as bread, rice, pasta, starchy vegetables, and more.
It is recommended to do some research in order to find the best carb blockers on the market and asking your doctor is the best before taking them. Always go for reliable and effective supplements.

How to Choose a Carb Blocker – 7 Tips
How do I choose a carb blocker? With so many different supplements on the market, it may be difficult to know which one will work for you.
Choosing the best fat blocker should be an individual affair. In other words, what works for your friends may not work for you.
It is important to understand that we all have differences in our metabolisms.
Some people report better and faster results on carb blockers, while others struggle to lose weight even on these supplements.
Unfortunately, no one has invented a magic pill for weight loss yet!
That being said, there are several important features you want your supplements to have.
When choosing a carb blocker, make sure to pay attention to the following:
1. Ingredients and safety
Just like with any other dietary supplement, your number one concern should be your health. It is important to only consume carb blockers that contain natural ingredients that you know are safe for you.
Keep in mind that not all manufacturers disclose all of the ingredients, so make sure it is a company you trust (see below).
Furthermore, it is best if you consult your doctor before choosing a carb blocker. Your doctor can advise you on the supplements that are safe for you to consume.
2. Is the company reliable?
While reputation is not everything, it is a very important parameter you should think about. Is the company known, and is it reliable?
What do you know about the manufacturer? You need to be aware of the status of your chosen brand before you invest your money.
Keep in mind that this is about your health, and you need to protect yourself. Make sure to do some research before you trust a specific company’s supplements.

3. How effective is this supplement?
You want your carb blocker to work, and you want it to work for you.
There are many starch blocker supplements promising effective results but do not trust the label. Make sure to read other people’s reviews and honest reports of results.
You want a carb blocker that works consistently and provides effective weight loss.
4. Carb blockers come in many different concentrations
Some capsules contain as few as 100 mg of a white kidney bean or another active ingredient.
Others contain 700 mg or even more of the active ingredient.
A more potent capsule might be more effective, but it can also prove to be a downside: stronger capsules also carry a higher risk of side-effects. Also, keep in mind that the daily dosage of white kidney bean should not go above approx. 3,000 mg. Keep this in mind when choosing your supplements based on potency.
5. Powder or capsules?
Many carb blockers come in capsules or tablets, but there are also those that are available as powders.
Generally speaking, there is no much difference between the two, as long as the ingredients and their concentration are the same. Some people find difficulty in swallowing capsules so the powder form is more suitable for them.
However, many people find powdered starch blockers to be too bitter. On the other hand, keep in mind that supplements that come in capsules tend to be more expensive.
6. Serving number
How many capsules are there in the bottle? How many servings? Keep in mind that you will need to take your carb blockers before each meal, which means anything from two to four or more capsules per day.
The number of capsules in a bottle is important. A supplement may seem cheap, but if it only contains a week’s worth of supplements it can turn expensive in the long run.
7. Price
While a price should not be your main reason for choosing a specific supplement, it is definitely a factor you want to take into account. Carb blockers are not very expensive, so it is possible to find an affordable solution. When choosing your supplement, make sure to pay attention to serving number, potency and other parameters.
Carb Blocker Benefits
There are many benefits advertised by carb blocker manufacturers but most of these claims are not backed up by scientific studies.
There are some studies done on animals, that do show the ability of carb blockers to prevent the secretion of enzymes responsible for breaking complex carbs.
Other studies demonstrated carb blockers’ benefits in suppressing hunger and in regulating blood sugar levels.
However, in general, there hasn’t been enough research done on carb blockers to provide definite proof of these supplements’ benefits.
Nevertheless, there are many users who claim that starch blockers are effective in terms of weight loss and suppression of hunger.
Here are the main best carb blocker benefits:
1. Weight loss
In essence, starch blockers help you lose weight by eliminating complex carbs from your overall calorie count. These supplements block the enzyme alpha-amylase, and without it, your body cannot break complex carbohydrates so they could be absorbed.
It means that calories from these complex carbs do not count toward your overall calorie count.
Consuming fewer calories on a daily basis leads to weight loss.
2. Suppressing appetite
Another benefit of carb blockers is that it can help prevent hunger. As a result, you consume less food and you feel full for longer periods of time.
3. Boosting your metabolism
Certain carb blockers claim to boost your metabolism and improve your energy levels which contribute to weight loss.
4. Regulating blood sugar levels
One of the best things about carb blockers is that they regulate your blood sugar levels. This can be beneficial for people who have a mild problem regulating blood sugar.
Studies showed that carb blockers prevented healthy people from getting high blood sugar levels after eating food rich in complex carbs.

Carb Blocker Disadvantages
If you wish to use carb blockers, you need to be aware of the possible side effects and other disadvantages that these supplements can bring.
While generally considered safe, carb blockers might not be for everyone.
Here are the main side effects of carb blockers:
1. Bloating and flatulence
Some people react in this way to carb blockers, particularly to those supplements that are very potent. Because carbs are not digested, they go straight to your large intestine. This can cause bloating and flatulence.
Sometimes, carb blockers work too efficiently. This can cause loose stools and diarrhea. It is more common with supplements that have a high concentration of the active carb blocker ingredient.
This is a rare side effect, but it can happen to some people as a result of taking carb blockers.
2. Dangerously low sugar levels
This side effect can happen to people with diabetes. If you have diabetes, you should not use carb blockers before consulting your doctor. This is a serious concern so make sure to take this warning seriously.
These side effects do not happen to everyone, and not with every single carb blocker.
However, make sure to pay attention to how you feel when you start using starch blockers.
If you notice any of these side effects, stop using the supplement and consult your doctor immediately.
3. Uneven results
Carb blockers simply work better for some people than the others. There is still not enough research to prove who is better suited for these supplements. One thing to note is that starch blockers seem to work better for people who consume large quantities of complex carbs.
4. Doesn’t work on simple carbs
One of the most important things to remember about carb blockers is that they don’t work on simple carbohydrates. Simple carbs are found in processed foods and many sweet foods. It means that you have to avoid these foods to lose weight. Carb blockers can only help you with complex carbs, such as those from bread, rice, potatoes (and other starchy veggies).
5. Not all complex carbs are blocked
Keep in mind that carb blockers do not prevent all of the complex carbohydrates from being absorbed. It means that you will probably receive certain calories from those carbs.
All supplements and their active ingredients have a safe dosage for a reason.
If you go above this, you can overdose on a supplement and have negative side effects.
To avoid this problem, make sure to consume your supplements as directed.
Never take more capsules than recommended on the package.

How to Take Carb Blockers
To stay safe and to maximize carb blocker results, make sure to follow the manufacturer’s instructions.
Generally speaking, it is best to take your carb blockers before you eat a meal rich in complex carbohydrates.
Starch blockers are most effective if taken 5-10 minutes before the meal. If you take it too early, they will be absorbed by your system before they can block carbs.
If you take them too late, they will not be able to prevent the absorption of carbohydrates.
Follow the manufacturer’s instructions. Typically, you should take 1-2 capsules before each meal.
However, make sure to check what is directed. Some supplements are taken in different ways than this.
Also, keep in mind that there is no point in taking a carb blocker if your meal doesn’t contain a significant amount of complex carbohydrates.
Remember: starch blockers work only on complex carbs and not simple carbs.
Do not waste a capsule on a meal that doesn’t contain bread, potatoes, starchy veggies, rice or other food rich in complex carbs.

They are generally safe, but you need to be careful about choosing the product that suits you best.
