What is CLA?

CLA, otherwise known as conjugated linoleic acid, is an omega-6 fatty acid.

More specifically, CLA actually refers to a family of 28 different isomers of linoleic acid, which is the most common omega-6 fatty acid found naturally.

CLA is found naturally in things like grass-fed beef and dairy made from grass-fed cows. It’s also found in non grass-fed beef, but in much smaller amounts.

In supplement form, the acid is often derived from vegetable oils, and closely mimics the effect of naturally produced CLA.

Benefits of CLA

Some potential uses of CLA supplements include:

Fat loss

CLA supplements are primarily marketed as a way to help lose weight. The evidence for this claim is mixed.

In animal trials, researchers found that CLA helped to increase fat burning, inhibit the production of fat, and reduce food intake (1, 2, 3). These findings suggest that CLA can have anti-obesity effects that may help to reduce body fat.

However, where human trials are concerned, the evidence is less clear-cut.

Several human studies found that CLA contributed to significant fat loss (4, 5, 6). However, a similar number of human trials found that CLA had no effect on fat loss at all (7, 8, 9).

With such conflicting information, it is difficult to draw a clear conclusion either way.

Despite the mixed results, meta-reviews of CLA supplementation have found that, on average, CLA can have a modest fat burning effect.

One meta-review found that CLA contributed to a 0.2lb fat loss per week for 6 months, for a total of ~4.8lb of fat loss, compared to placebo (10).

A separate review showed that CLA resulted in an extra 3 lb of fat loss compared to the placebo group (11).

These studies suggest that conjugated linoleic acid can have a positive effect on weight loss efforts, although more research is needed.

Muscle mass

CLA manufacturers also claim that CLA supplements may help to increase lean muscle mass and protect lean muscle mass during fat loss.

These claims are largely overblown.

Some studies have found that CLA supplementation, when combined with resistance training, can increase lean muscle mass more than the placebo control group (12, 13).

At the same time, several studies have concluded that CLA had zero effect on lean muscle mass (14, 15). More research is needed.

Overall, CLA may have a moderate effect on fat loss, but there is mixed evidence; more research is needed.

Side Effects

Taking too much of ANY supplement can be dangerous, so be sure you follow the dosage instructions – no matter what kind of supplement you’re taking.

While some people don’t experience CLA side effects, the following effects are common in those that do:

  • Stomach upset, including nausea and diarrhea
  • Fatigue

Again, side effects can become much more severe and potentially dangerous if you take too much of a given supplement.

Always follow dosing instructions and speak to your doctor before taking any supplements.

There is also some concern in the scientific community related to the production process involved in making CLA supplements.

These supplements are manufacturer using potentially unhealthy vegetable oils.

While naturally derived CLA found in foods is completely healthy, some studies have shown conflicting information when it comes to the types of manufactured conjugated linoleic acid found in supplement form.

For example, one study linked increased CLA supplementation with a rise in fat within the liver, a condition which may increase the risk of developing diabetes and other health issues (16).

Another linked it to a rise in inflammation, a potential complication for people with metabolic syndrome (17).

How To Take CLA

As with any supplement or health product, it’s vitally important to know how and when to take CLA supplements.

More importantly, it’s important to not take too much.

For the most part, you should simply follow the instructions on the label of the supplement you’re taking. It’s important to not take too much of ANY supplement, including CLA.

Generally, these supplements will come in a single-capsule serving size, usually containing somewhere between 500-1000mg of CLA.

It’s also recommended to consult with your doctor before you begin taking any new health supplements.

Lastly, you should take CLA at mealtime. It’s not recommended to take on an empty stomach and that can cause minor stomach discomfort in some people.

Most supplements you can take 1-3 times per day, depending on the dosage amount.

Again, check the label to see what the manufacturer recommends, and talk to your doctor if you have any questions.

What to Look for in a Good CLA Product

In order to find the right CLA supplement for you, it’s important to shop around.

Here are some things you should look for when shopping for the best option.

  • Amount of CLA – obviously, the first thing you should take a close look at is the actual quantity of conjugated linoleic acid in each capsule/serving. Now, keep in mind that it’s not possible to have pure CLA, so most products will say something like “contains 1250mg safflower oil, standardized to 80% CLA”. Most products will also list the amount of active CLA in each serving. In general, expect 800-1000mg per serving. When comparing prices of two different products, keep in mind the differing serving sizes/amounts of active ingredients.
  • Brand quality – if you buy one of the products listed above, you can rest assured you’re buying a good product from a good company. On the other hand, if you shop elsewhere you can not necessarily count on that to be true. Always buy from reputable companies, no matter what type of supplement you’re buying. If you shop elsewhere, be sure to read CLA reviews to determine quality before making a purchase.
  • Community feedback – again, if you choose to shop elsewhere and don’t buy a product listed below, we recommend that you at least read CLA supplement reviews on whatever retailer’s site you’re on. Amazon is a good resource with lots of customer reviews.
  • Value for money – as with anything, you’ll want to find a good product at a fair price. While you don’t necessarily want cheap CLA supplements, you’ll want to find an option that fits your budget and needs. Be sure to compare per serving prices, and not just compare the prices of the whole package.
