In a study published in Nutrition Research, researchers at McGill University, Canada, and the University of Sydney, Australia, investigated the effect of CLA on parathyroid hormone (PTH), which is a marker for bone resorption. The study also showed that the CLA was not effective at reducing intact or bioactive PTH levels. The results suggest that CLA may help the immune system and prevent the negative effects of overtraining.
CLA supplements for men should be made from only natural ingredients. Avoid those that contain unnecessary ingredients, such as preservatives or colors. The supplement should also be tested by a third-party agency, such as the U.S. Pharmacopeia. If you have diabetes or are taking blood-thinning medications, consult a medical professional before beginning a CLA supplement. It is also not recommended for women who are pregnant or breastfeeding.
Though CLA may not be as popular as other supplements, it does have a lot of potential. When used in conjunction with good training and nutrition, it can help improve body composition and promote weight loss. In addition to weight loss, it helps maintain muscle mass during the bulking phase. You can take it as a pre-workout shake powder or soft gels during meal times. However, you must note that body fat reductions from CLA supplements are not always translated into pounds.
