Looking for the best CLA supplements? We’ve got you covered.

Conjugated Linoleic Acid (CLA) is a type of omega-6 fatty acid. It naturally occurs in meat and dairy products, especially grass-fed animals. [1] Despite being trans fat, it is considered healthier as it occurs naturally in the foods we eat, unlike industrial trans fat. CLA supplements have been recognized as an important tool for weight loss and have been a favorite within the body-building community. 

Numerous studies have been done to know its health and wellness benefits. A review paper from 2015 states that CLA aids in breaking down body fats. It also promotes changes in lipid metabolism which can result in the modulation of the immune system, reduction of body fat, and reduced blood glucose. [2]

Another study showed that consuming 7.2g of CLA daily led to increased leg press gains, skin-fold corrected arm girth and overall body mass. It’s important to note that they accompanied it with a bodybuilding regimen. [3] However, some suggest that the way CLA increases lean muscle mass and decreases body fat mass needs to be studied more.

The amount of CLA you consume depends on your diet or the supplements you take. Most people consume CLA through their daily diet. The CLA in dietary supplements is not derived from food, but rather, is made chemically. 

If you’re interested in commencing a CLA supplement, we’ve got a list of some of the best CLA supplements on the market for bodybuilding, weight loss, and more!

How To Choose the Best Conjugated Linoleic Acid Supplement

As mentioned, meat and dairy are sources of CLA but if your daily diet does not include these foods in bulk, you may need to take supplements. Let’s discuss the main factors when choosing the right dietary supplement for you. Remember, not all supplements are created the same.

Check for Additives and Fillers

While additives and fillers serve some purpose, they offer no nutritional value. Additionally, those ingredients can trigger allergic reactions so be cautious. If possible, opt for supplements with minimal or no additives and fillers at all.

CLA Supplement Dosage Recommendations

It’s extremely important to know the dosage you need before making a decision. CLA found in supplements are larger than what is found in meat and dairy. Large doses can increase the risks of side effects. According to animal and human studies, large doses might lead to insulin resistance and inflammation. [4

As you can consume it through your diet already, your supplemental dosage will depend on your needs. Studies suggest that the ideal daily dosage is between 3 grams and 6 grams.  The minimum dosage may increase depending on your weight or body composition. Consult your doctor or nutritionist to guide you when making a decision. 

Know the Ingredients/CLA Content

The supplements are not made of CLA found in foods. It is chemically extracted from different oils high in linoleic acid such as sunflower, soybean, and safflower oils. The supplements made from these oils have mixed isomers rather than natural CLA.

When choosing the perfect supplement for you, pay attention to the amount of CLA in the supplement. For instance, if the packaging says the supplements contain 1250g of ingredients, it is more than likely that 80% of it is active CLA. Taking a look at the CLA content per capsule will give you an idea of how many tablets you need to take daily.

Possible Side Effects of CLA Supplements

Just like other dietary supplements, CLA can cause some side effects. Large doses can cause diarrhea, nausea, and insulin resistance. [5] It can also affect those with diabetes because CLA can worsen how your body absorbs sugar. It can lower good cholesterol as well.

There are not a lot of studies regarding its safety, hence, doctors don’t recommend pregnant women and children to take CLA supplements. Also, before taking any forms of CLA supplements, it’s better to consult your doctor or other health practitioners. Be extra cautious especially if you’re taking other medications.

Frequently Asked Questions (FAQ):

Is CLA good for fat loss?

Yes, it can help you to lose fats. Supplements should be combined with healthy eating and exercise.

Can CLA make you gain weight?

So far, there is no evidence of this. Moreover, unless you stop taking the supplements or if you don’t accompany it with exercise and healthy eating.

Is CLA bad for you? 

Not necessarily. It depends on each customer. In addition, some reported side effects while others are completely fine after taking the supplements.

Can CLA work for belly fat? 

A study from the International Journal of Obesity discussed the possible connection of CLA and abdominal fat reduction in overweight men. [6] However, another study found that CLA did not reduce waist circumference. [7] In conclusion, it will depend on each individual using the supplements and their lifestyles.

When is the best time to take CLA?

The best time to take CLA supplements is with any of your main meals. People have noted that they experience the best results from CLA supplementation if it is taken with food. Hence, you can take your CLA supplements during or right before your meal.

Is CLA + carnitine good for you?

The effects of this combination will differ from person to person. L-carnitine may help to burn belly fat, support weight management, and enhance your exercise performance. Since L-carnitine has similar benefits to CLA, you may find a combination of the two in certain supplement brands. Theoretically, this combination should be more effective in helping you achieve a healthy weight and burn belly fat. But more research needs to be conducted to confirm this.

Bottomline: Best CLA Supplements

Conjugated Linoleic Acid is an omega-6 fatty acid found mainly in dairy and meat products. Weight loss and fat loss are among the many health benefits of CLA, making it an ideal ingredient in supplements. Choosing the right high-quality supplement can lead you to achieve your goals. Just don’t forget to accompany the supplements with the right diet and an active lifestyle.
