If you’ve been on a journey to shed body fat or tone up, chances are you’ve come across CLA supplements in your search. Short for conjugated linoleic acid, CLA is a naturally occurring fatty acid found in meat and dairy that’s often marketed as a fat-burning aid.
But with so many options on the market—and conflicting opinions online—it’s tough to know which CLA supplements are actually effective. In this guide, we’ll break down how CLA works, what the science says, and which products stand out based on quality, user reviews, and expert recommendations.
Let’s explore the best CLA supplements for fat loss—and how to use them wisely.
What Is CLA and How Does It Support Fat Loss?
CLA, or conjugated linoleic acid, is a type of omega-6 fatty acid that’s been linked to reduced body fat in several studies. It works by influencing enzymes and genes involved in fat metabolism. Essentially, it may help your body use stored fat as energy, making it easier to lean out—especially when combined with a healthy diet and exercise.
Although CLA is found in grass-fed beef and dairy products, the amounts are small. That’s why many turn to CLA supplements to achieve a higher, more consistent dose.
According to research published in The American Journal of Clinical Nutrition, CLA supplementation may lead to modest fat loss over time, particularly in the abdominal area1. However, results tend to vary based on lifestyle, dosage, and product quality.
Are CLA Supplements Safe?
For most people, CLA supplements are considered safe when taken as directed. Common dosages range from 2,000 to 3,400 mg per day, which has been shown to be both effective and well-tolerated in multiple studies.
That said, some individuals may experience mild side effects such as:
- Digestive discomfort
- Fatigue
- Nausea
It’s always smart to consult your healthcare provider before adding any supplement—especially if you have underlying health conditions.
What to Look for in a CLA Supplement
Not all CLA supplements are created equal. Here’s what to keep in mind when shopping for a quality product:
- Purity—Look for products with 80% standardized CLA content. This ensures you’re getting an effective dose of the active compound.
- Non-GMO and Third-Party Tested—Independent testing adds peace of mind regarding what’s inside the bottle.
- Transparent Labeling—Brands that list dosage per softgel and provide sourcing information tend to be more trustworthy.
- Value per Serving—Check the cost per daily dose—not just the bottle price.
Now that you know what to look for, let’s highlight some of the top CLA supplements that meet these standards.
Regular bowel movements are a good sign your gut is functioning properly. On the other hand, chronic constipation, diarrhea, or sudden changes in your stool may suggest something’s off in your digestive system.
This could mean your gut bacteria are unbalanced or that you’re not digesting and absorbing nutrients efficiently.
