Only Protein Meal Replacement Review

Only Protein Meal Replacement

Only Protein Meal Replacement is exactly as it sounds: an all-in-one meal replacement with protein, vitamins, and minerals the body needs for a well-balanced meal.

Meal Replacement by Only Protein is calorie friendly, weighing in at 103 calories per serving and is advertised as a great on-the-go alternative for “clean eating.”

This review covers everything you need to know about Only Protein Meal Replacement, so you can decide if it is worth trying.

Are the Ingredients Powerful?

There are several ingredients and proprietary blends in Only Protein Meal Replacement’s nutritional profile. These blends don’t list individual ingredient amounts.

Instead of discussing all the ingredients, I highlighted a couple of key components.

New Zealand Protein Blend
Only Protein Meal Replacement features whey and casein in a couple different forms:

Whey Concentrate is the least processed whey form and is around 80% protein by weight. [1]

Whey Isolate is slightly higher in protein content than concentrate, over 90% protein by weight. [1]

Whey proteins are absorbed quickly and offer dramatic “but short increase[s] of plasma amino acids.” [2]

Calcium Casienate is derived from casein, the main protein present in milk. It is a slow digesting protein, which means it offers a longer, sustained release of amino acids. [2]

The Centers for Disease Control and Prevention recommends consuming around 56 g protein per day. [3] Only Protein Meal Replacement provides 18 g protein per serving, so users need to obtain additional protein from other sources.

Proprietary Protein Blend
This blend contains 3 ingredients. Once again, individual ingredient amounts are not disclosed.

Garcinia Cambogia is believed to aid in fat storage prevention and curb appetite. Researchers indicate, however, whether this activity occurs in humans is unclear. [4]

L-Carnitine is studied for its fat burning potential.

Evidence reveals l-carnitine optimizes fat oxidation when administered in 3 g during a 10-day experimental period. [5]

L-carnitine amounts in Only Protein Meal Replacement are smaller than the clinical amount because they are 1 of 3 ingredients in a 195 mg blend.

Hoodia Gordonii is an ingredient believed to aid in weight loss. However, according to Louise Chang, MD, evidence supporting its benefits is inadequate. [6]

Protease is an enzyme that aids in protein digestion, and supplemental forms are especially beneficial for those suffering from pancreatic disease.

One study shows protease supplementation improved muscle function and attenuated muscle strength losses post exercise when administered in 5.83 g per day. [7]

There is 200 mg protease in Only Protein Meal Replacement. Consequently, I don’t believe protease’s muscle benefits are prominent in Meal Replacement.

Lactase is an enzyme used to aid in digestion of milk and dairy products in those who are lactose intolerant. [8]

According to academic authorities, those who are lactose intolerant may suffer from lactase deficiency. [9] A clinical study indicates 400 mg lactose or less can be used safely. [10] Only Protein Meal Replacement contains 200 mg lactase.

Amino Acid Profile provides several essential amino acids like isoleucine (1170 mg), leucine (1920 mg), and valine (1030 mg).

These amino acids are branched-chain amino acids and are known for their collective ability in reducing muscle breakdown, bolstering muscle control, and optimizing athletic performance.

One study in particular shows a mixture providing 5 g BCAA improved muscle soreness and recovery following intense compound leg exercises to fatigue. [11]

Is Only Protein Meal Replacement Affordable?

Only Protein Meal Replacement comes in powder sticks and jug form and is available in vanilla and chocolate flavors.

Each Only Protein Meal container provides 15 powder sticks, and each jug provides 21 servings. Depending on how you use Only Protein Meal Replacement, the stick form may better suit on-the-go needs whereas the jug provides more servings.

Prices per jug vary, ranging from $32.98-$45.00, and the sticks retail for $28.99-$40.00.

Are Customers Satisfied?

Although there aren’t many, user reviews are positive. I found the following user review on a third party retailer, the rest are testimonials listed on OnlyProtein.com. Here is a look at what users are saying:

“This is absolutely one of the best protein shakes that I have ever had!” says Yazmine101 on BodyBuilding.com. “I have gained over 10 lbs of muscle. I look and feel great!” She says the chocolate flavor tasted exactly like a milkshake. “I couldn’t believe how great it tasted.”

“I like this product because its only 103 calories per serving!” says Korben on OnlyProtein.com. “I am addicted to it and the way I feel. It does not upset my stomach like other proteins or meal replacements. The Vitamin B12 for sure gives me energy and allows me to work hard at the gym.”

Landen Powell says he has been using Only Protein for a few weeks and loves the results. “Can’t believe the difference I feel out on the track and in the gym. It’s exactly what you need for the high strength-endurance sport that we compete in!”

What Is the Best Way to Use It?

Users are instructed to add 1 serving to 120-180 ml water. Use as needed.

Some users indicate they use Only Protein Meal Replacement to replace meals occasionally, while others supplement their meals with additional protein from Meal Replacement.

Are There Any Side Effects?
The company doesn’t specify whether there are any long or short term side effects. It does indicate Only Protein Meal Replacement is manufactured in a GMP (Good Manufacturing Practice) certified facility.

Only Protein Meal Replacement contains milk by-products.

Should You Buy It?

Only Protein Meal Replacement appears to be an average meal replacement supplement. It doesn’t provide all necessary daily required protein amounts, however.

The price per serving is affordable depending on where you purchase it. The best deal I found for the Only Protein Meal Replacement sticks was on eSupplements.com. This third party retailer stands behind all products purchased from them, offering a 60-day money-back guarantee.
