Promax Protein Bar Supplement Review

Each Promax Protein Bar provides your body with 20 g of protein, 40 g of carbohydrates, 4.5 g of fat, and 270 calories. They’re also packed with 18 vitamins and minerals, including 25% of your RDA for Vitamin A and Vitamin C.

But unlike most protein powders, there’s no creatine, L-glutamine, or BCAAs. So are they an effective source of pre-workout and post-workout nutrition?

In this review we’ll compare Promax to two other top-rated protein bars; CLIF Builder’s Protein, and Optimum Nutrition Opti-Bar.

Comparisons include the levels of protein, carbs, and fats, as well as the cost per serving, flavors, customer feedback, and total calories.

This is to guarantee you only buy the best protein bar for your current diet and fitness goal. Whether that’s weight loss, lean muscle gain, bulking, or simply to boost your daily protein intake.

Promax Protein Bar Ingredients

Promax Protein Bar Ingredients

As with most protein bars, nutrient levels vary slightly depending on which flavor you prefer. But on average, Promax Protein Bars are considered high-carb, with 37-40 g per serving.

That’s compared to low carb protein bars, like MuscleTech Mission1 Clean Protein Bars, which have 22 g of carbs per serving. This also has a big impact on the calorie count, with Promax bars delivering around 280 calories per serving, compared to just 200 with Mission1.

So what if you need more protein per bar?

There are few protein bars on the market that offer more than 20 g per serving. MET-Rx have a meal replacement bar called Big 100, which has 30 g of protein, but is high carb (46 g) and high in calories (400 per bar).

If you need more protein than 20 g per serving, you’re best option is protein powders or RTDs instead of bars.

In terms of the protein blend, Promax contains a combination of soy protein isolate, whey protein concentrate, and calcium caseinate.

Most protein bars use a combination of protein isolates, as isolates contain approximately 90% pure protein. However, isolates require additional processing, which means a higher cost. That’s why Promax bars balance the more affordable whey concentrate (roughly 80% pure protein) with whey isolates to deliver a high protein bar that’s more affordable than others on the market.

At the time of writing this review, a box of 12 Promax Protein Bars cost $14.79, compared to $24.49 for a box of 12 MuscleTech Mission1 bars, which have just 1 g more protein, 18 g less carbs, and 80 less calories.

Weight loss or weight gain?

Promax Protein Bars are designed to assist with the support of lean muscle growth and recovery, as part of a regular exercise and nutrition program.

Protein bars for weight loss are difficult to find. Your best option is finding a high protein, low calorie, low carb protein bar that helps put your body in a caloric deficit each day. Quest Protein Bars are an excellent example. They contain just 6 g of fat, 20 g of protein and as few as 170 calories.

For weight gain, you’ll need to consume sufficient protein and enough calories from healthy foods to put your body in a daily caloric surplus. This is where Promax Protein Bars would be a better choice.

If you need more calories and don’t mind the extra carbs, MET-Rx Big 100 bars are an excellent option (30 g protein, 47g carbs, 400 cals).

Who are they designed for?

Runners, weightlifters, athletes, or anyone looking for a quick and easy way to increase their protein intake.

When is the best time to take it?

The high carb content of Promax Protein Bars means they’re ideal for pre-workout nutrition, or as mid-morning/mid-afternoon snacks.

You can also enjoy one as a nutritious snack anytime throughout the day. But as a general guide, whether you’re looking to diet or add lean muscle, carb intake should be drastically reduced after 5-7pm.

Save money with Amazon

If you’re looking to save money on your monthly supplement order, you might want to consider the Amazon Subscribe & Save program.

Subscribe & Save allows you to unlock savings of up to 15% on a wide range of sports nutrition products, including Promax Protein Bars (selected flavors only).

You can save 5% with a subscription to 1 product, or save the full 15% by subscribing to 5 products, provided they’re all delivered to the same address. The delivery schedule can be set from monthly, up to once every 6 months.

Although 5 products might sound a lot, if you already supplement with a protein powder, multivitamin, creatine, BCAA, and glutamine, the savings can soon add up. But it’s best to order before you run out of your current supplements, because Amazon set the day of the month each order is sent (same day each month e.g. 14th.).

Who are Promax?

Since 1996, Promax have been one of the market leaders in high protein energy bars. The original protein bar product line has since expanded to include Promax Lower Sugar, which use the stevia sweetener in their recipe to keep the sugar level low.

Promax Protein Bars are best for anyone that’s looking to either bulk up with lean muscle, or fuel a lifestyle that includes a lot of physical activity.

That’s because their bars are made with a 2:1 carbs to protein ratio, in contrast to the more traditional 1:1 ratio followed by companies like Optimum Nutrition (Opti-Bars) and MuscleTech (Mission1 Clean).

Review Overview

Overall Review Rating

4.5 / 5

So, are the Promax Protein Bars worth buying?

The 2:1 protein to carbs ratio is great for anyone that's looking to bulk up and gain muscle, or needs energy before physical activity, such as cycling.

However, most of this energy is simply from the high sugar content, with 30g per bar. This is 10x the sugar you get with bars such as MuscleTech Mission1 Clean and Pure Protein Bars.

Although they're only available in 2 flavors (Chocolate Fudge and Peanut Butter Chocolate), Lower Sugar Promax Protein Bars are also available. These contain just 9g of sugar per bar, 33g of carbs, 18g of protein, and 210 calories.

The original Promax Protein Bars are also excellent value for money, and some of the cheapest protein bars on the market.

At the time of writing this review, you could buy a box of 12 for $14.79 ($1.23 per bar). That's compared to $23.97 ($2 per bar) for Quest Bars, and $25.99 ($2.17) for RXBAR Whole Food Protein Bars.

Overall, as specialists in protein bars, and with over 20 years experience in their taste and macro split, it's clear that Promax deserve their hundreds of high review ratings. Their protein bars are delicious, great value for money, and can provide an effective energy boost pre-workout.
