Does Pro JYM Work?

Our researchers came up with a detailed Pro JYM ingredient breakdown.

Whey Protein Isolate

Whey protein is one of the leading supplements used by athletes and fitness enthusiasts. Research reviewed in Metabolism suggests that the properly timed ingestion of whey protein can increase muscle gains.

Whey protein can also play a role in fat loss. A randomized controlled trial published in the Journal of Nutrition examined the effect of whey protein on obese adults. Participants who ingested whey protein lost considerably more body fat compared to the control group.

Micellar Casein

Micellar casein is a slow-digesting form of protein. According to the Journal of Strength and Conditioning Research, combining fast-digesting protein like whey with slow-digesting casein increases the supplement’s anabolic effect.

Mile Protein Isolate

Milk protein isolate is the natural form of milk protein. A randomized controlled trial reviewed in the Journal of Nutrition suggests that a blend of different proteins promotes better protein synthesis in human muscles.

Egg White Protein

Protein from egg whites is also included in the Pro JYM protein blend. Egg white protein is a medium-digesting protein that’s packed with branched-chain amino acids. Branched-chain amino acids increase protein synthesis, according to the American Journal of Physiology, Endocrinology, and Metabolism.

Weight Loss

Pro JYM and Weight Loss

There is some evidence that whey protein can aid fat loss. A 2008 study featured in Nutrition and Metabolism (London) found that supplementation with whey protein reduced body fat in obese individuals without affecting lean muscle mass.

A meta-analysis published in the Journal of the American College of Nutrition suggests that individuals who take whey protein supplements and regular exercise lose more weight than those who rely on exercise alone for weight loss.

The studies mentioned above are promising, but participants in both studies combined a whey protein supplement with resistance training. You can’t expect to lose weight by drinking a protein shake if you’re not willing to exercise.

Product Comparison

JYM Pro JYM vs Gold Standard

We compared the product vs. the Gold Standard whey protein. Both products are ultra-premium protein powders, but Gold Standard doesn’t contain milk protein isolate of protein from egg whites. Pro JYM is slightly more expensive compared to the Gold Standard.

Pro JYM vs. Mass JYM

Our researchers compared this product with Mass JYM. Mass JYM combines Pro JYM’s blend of proteins with added fiber, fats, and carbohydrates to create an ultra-premium protein powder.

Side Effects

Pro JYM Side Effects

No serious reactions to the whey protein have been reported. Any whey protein can cause mild gastrointestinal discomfort.


How to Use Pro JYM

Add one scoop to 12 ounces of milk or water. Use less liquid for a thicker consistency. Drink a shake 30 minutes before and after a workout.

You can drink a shake with breakfast on days when you won’t be hitting the gym.

What Users Are Saying

What Users Are Saying

“Exactly as advertised. Tastes great, no sugar spike, mixes well in ice cold water without clumps. PBnC flavor is amazing. Not super sweet, tastes just right. I’m hooked on this brand. Great for post-workout or post-bike ride recovery.”

“I’ll start by saying I love Jym products and follow Doc Stoppani. It was disappointing to actually not like this flavor, it was very chemically to me. I will stick with the staples, Tahitian Vanilla Bean and chocolate peanut butter cup!”

“I started using JYM Protein for the past year and it has not disappointed me. I found the smores flavor to be one of my favorites.”
