Grass-Fed Whey Protein Isolate

Rapidly absorbed, complete protein source rich in branched-chain amino acids for muscle recovery.

Grass-Fed Whey Protein Isolate

Egg White Protein

High-quality protein source that’s easy to digest and supports lean muscle growth.

Egg White Protein

Natural Peanut Butter

Unprocessed peanut butter gives our protein bars a rich texture while providing quality fats.

Natural Peanut Butter

Natural Almond Butter

Rich in healthy fats, protein, and micronutrients for satiety and heart health.

Natural Almond Butter

Grass-Fed Whey Protein Isolate

Grass-fed whey protein isolate is a complete protein source that's rapidly absorbed and easily digestible. Being derived from the milk of grass-fed cows, our whey protein isolate is an excellent source of essential amino acids and branched-chain amino acids (BCAAs), which are crucial for muscle repair and growth [1].

Grass-Fed Whey Protein Isolate

Egg White Protein

Egg white protein is another exceptional complete protein source that promotes muscle repair; in fact, egg whites have the highest attainable protein-digestibility corrected amino acid score (PDCAAS) [2]. They are also a good source of B vitamins and selenium.

Egg White Protein

Natural Peanut Butter

Natural peanut butter contains a generous amount of protein, healthy fats, and fiber, which promote satiety and heart health. It is also rich in vitamins E and B3, as well as minerals like magnesium, supporting overall micronutrient intake without the added sugar or hydrogenated trans-fat found in more processed versions.

Natural Peanut Butter

Natural Almond Butter

Almonds are a nutrient-dense nut packed with heart-healthy monounsaturated fats, protein, minerals, and dietary fiber, making them a perfect complement to our protein bars. Almonds are also nutritious due to their magnesium and antioxidant content, which are commonly lacking in the diet.

Natural Almond Butter

Gluten-Free Rolled Oats

Oats are rich in soluble fiber, which promotes healthy digestion and helps maintain cholesterol balance. In addition to their fiber content, oats deliver a spectrum of essential minerals — including magnesium, phosphorus, and iron. Naturally gluten-free and easy to digest, they form a wholesome base for our Protein+ Bars that’s as functional as it is filling.

Gluten-Free Rolled Oats

Dates

Unlike refined sugars, dates provide a slow, steady energy release thanks to their fiber content and low glycemic impact. They’re also loaded with essential minerals like potassium, copper, and manganese. Beyond their nutrition profile, dates give our Protein+ bars a chewy, satisfying texture and a naturally sweet flavor .

Dates

Honey

Honey is a natural sweetener with a diverse nutritional profile, including trace amounts of vitamins, minerals, enzymes, amino acids, and antioxidants. Unlike refined sugars, honey contains flavonoids and phenolic acids that contribute to its antioxidant properties, offering potential health benefits such as anti-inflammatory effects. Its lower glycemic index than table sugar means it has a more stable impact on blood sugar levels.

Honey

Dairy-Free Chocolate Chips

Dairy-free chocolate chips provide the rich sweetness and flavor of traditional chocolate chips without using milk products and have a low sugar content. They are made with unsweetened chocolate, cocoa butter, and a touch of cane sugar.

Dairy-Free Chocolate Chips

Sea Salt

Sea salt is a natural source of numerous electrolyte minerals, notably magnesium, sodium, and potassium, adding not only a dash of flavor but also essential nutrients to the final product.

Sea Salt

Tapioca Syrup

Tapioca syrup, derived from the starch of the cassava root, is a natural sweetener that offers a gluten-free alternative to corn syrup. The body rapidly absorbs tapioca syrup, providing a quick energy boost to keep you moving.

Tapioca Syrup

Coconut Oil

Coconut oil is a dense source of medium-chain triglycerides (MCTs), a class of "healthy" saturated fats that support metabolism and energy production [3]. It also provides a soft, chewy texture to our Protein+  bars.

Excellent Protein Bars

The Oatmeal Chocolate Chip bars have great taste with clean ingredients. Sweetened with honey and dates (no sugar alcohols), whey protein isolate and no additives of any type. Have tried all four flavored bars TL offers and they are all excellent. My only issue is a couple of the bars are a little high in sodium. Would like to see TL lower the sodiuim content on those bars as it's not necessary.

Great tasting and filling!

Excellent taste and ingredients profile. It’s less about protein and more like a mini meal replacement. Keeps me full longer than others with similar macros. If I had one complaint it would be that they are a bit greasy to the touch, but that’s not really an issue.

Great on the go

Like the taste and perfect for grabbing and having handy on busy days. Only complaint is stock on hand… and I think that shipping them in the summer to AZ is not going to work.

Added sugars from a clean company ? Sketch for sure

Curious why a company that claims to be so clean is using added sugars won’t purchase again there other products don’t contain added sugars and are great I have yet to see a solid protein bar company that can effectively not use added sugar it’s mind blowing

Frequently Asked
Questions

When Is the Best Time to Eat a Protein Bar, and Can it Replace a Meal?

Protein+ Bars can be eaten any time you want a healthy meal replacement or snack, though you might need to eat more than one bar if you're using it as a large meal replacement. We typically recommend Protein+ Bars after a workout, when you don't have time to eat a whole-food meal, or when you want a high-protein snack throughout the day.

What Should I Look For in a Protein Bar?

This depends on your goals and dietary needs/restrictions; however, it's important to look for a protein bar that is made with healthy, natural ingredients. In addition, be cautious when you see protein bars labeled as "sugar-free" or "low net carbs" as they very likely contain artificial ingredients and sugar alcohols.

Is it Better to Have Protein Bars or Protein Shakes?

Either of these options are a good, protein-rich food source but it depends on your macronutrient intake goals and dietary preferences/restrictions. 

Protein shakes likely provide more protein per serving, but may not be as filling as a whole-food protein bar like our Protein+ bars due to the inclusion of complex carbohydrates and healthy fats.

Are Protein+ Bars Gluten-Free?

While many of the ingredients in Protein+ bars are gluten-free, the product as a whole is not tested for traces of gluten. Therefore, we cannot guarantee that Protein+ Bars are gluten-free.

Note that we use gluten-free rolled oats as a healthy carbohydrate source.
