CLA Side Effects Review - 5 Things You Need to Know


From time to time, we encounter a product needing additional attention, like CLA, so in this review we will concentrate on CLA side effects. (Feel free to read our full CLA review.) We took a close look at the ingredients and clinical research. We chose to read through hundreds of dieter comments. We then summarized the info to give you the bottom line.

CLA Side Effects can be purchased through Amazon.

What You Need to Know

CLA or conjugated linoleic acid is an essential fatty acid found in various foods such as eggs, milk and beef. The ingredient can’t be produced by the human body. You can take CLA in pill form. Typically, dieters take one capsule per day, which supposedly increases metabolism and weight-loss. It’s helpful that the supplement can be consumed in pill and powder form.

CLA, in its original form, was discovered in 1978. The supplement is available to purchase through various retail and health food stores. We do like that the product is affordable and it has been around for decades, but read on…

The first concern with CLA side effects was jitteriness. “CLA is intended to boost metabolism and increase weight-loss,” said our Research Editor. “You don’t expect the ingredient found in everyday foods to cause adverse reactions.”

“I started taking this product 2 days ago and I am dizzy. Every time I take it I feel lightheaded,” commented a customer.

“What bothered me was hours later I still felt jittery and wired. I took the serving at around 2:30 p.m. I figured it would eventually pass but it didn’t. I attempted to sleep at 1 a.m that night (almost 12 hours later) and I still felt uncomfortable and anxious,” reported a user.

Stomach Issues

Based upon some customer comments, the CLA side effects included stomach issues. “Every time I take this I get very sick to my stomach. I’m done feeling like crap, I’ve tried this at least five times and each time I feel like I’m going to have to run to the bathroom,” reported a user.

“Made my stomach upset and made me flushed in the face every time I took it,” offers a consumer.

“I have been taking this for 3 and a half weeks, the first week and a half it caused stomach discomfort with everything I ate,” said a dieter.

We’ve researched lots of products and we’ve found it takes something simple, like jitteriness, to cut down your chances of long-term success. If CLA side effects are an issue, the dieter needs to take that into consideration.

The Science

There are studies suggesting CLA will assist with weight-loss, but the findings were mixed. According to the Journal of International Medical Research, “CLA reduces body fat but not body weight in healthy exercising humans of normal body weight.” Also, the American Journal of Clinical Nutrition states,”A 3.4-g daily CLA supplementation for 1 y does not prevent weight or fat mass regain in a healthy obese population.” At DietSpotlight, finding concrete evidence supporting claims is critical. If there’s no real proof, that’s concerning.

The Bottom Line

After taking a comprehensive look at CLA side effects, we’ve come to a conclusion. We like that the supplement is widely available and that it’s found in foods, but we can’t recommend it because the published scientific research is inconclusive. Plus, we’re concerned about the potential side effects caused by CLA.

If you want to shed those extra pounds, we recommend going with a supplement with no side effects that’s supported by published clinical research.

Dietspotlight Burn is among the best supplements we’ve seen this year. The product’s formula is a four-ingredient proprietary blend, which has been shown in published scientific studies to accelerate fat loss and enhance metabolism. We checked and there’s no mention of negative side effects. Our look into the product did reveal dieters are seeing great results.

Additionally, the company that makes Dietspotlight Burn is confident in the supplement, so they’re offering a Special Trial Offer, which is quite the deal.
