Expert Reviews

What experts liked

The Lemon Zest vegan Luna Bar has 6 grams of fat with only 2.5 grams of saturated fat making it a heart healthy snack option. There is only 95 milligrams of sodium, which is comparatively low when looking at other plant-based nutrition bars. This will help keep blood pressure regulated but replace any lost sodium stores if using the bar like a post-workout snack or mini-meal. The bar has a small amount of potassium (120 milligrams) per vegan nutrition bar to help with electrolyte balance.
This one has no high-fructose corn syrup, no GMO's, and no artificial flavors or sweetener. It's also 70% organic so it's one of the better options out there when it comes to purity of ingredients.
The ingredients profile of this item is a high-quality prifile of organic oats, a blend of delicious sugars and a low glycemic index. With this, individuals can expect not only an energy bar that is delicious and has complete proteins, but it also focuses on muscle recovery due to the great nutrients and amino acids.
The company claims that they have created a dietary bar that meets the needs of active and athletic women by providing them with the necessary nutrients their body needs. According to their website, the Luna Bars are gluten-free and made to give you energy throughout your day. They also claim that the bars are made of organic ingredients along with fiber and protein.
Luna Bars contain soy, but are 100% gluten-free. Lower in fat and sugars than other brands, Luna bars may be a good option for weight management support as well.
Since these bars have good protein, fiber, no artificial ingredients or preservatives, and 70% of the ingredients are organic, I like having them for Lu as an emergency stash for traveling and afternoons of unexpected energy crashes in my active kid.
They're made with a protein grain blend that contains soybeans, milled flaxseeds, and other ingredients that show how vegans get their protein. The bars also contain rice syrup, dried cane syrup, vanilla extract, and other natural sweeteners that help to make them taste SO GOOD.

What experts didn't like

Some people felt the marketing is sexist.
Can taste the protein flavor.
Soy protein is derived from plants and can offer many benefits for women, such as an increase in estrogen, and muscle repair and growth, as stated on WebMD. But since the Luna Bar nutrition label fails to disclose the dosage of these ingredients, you don’t know if you are getting enough to have a real effect on your body. Even worse, you don’t know if you are not eating too much.


More and more people are turning to healthy foods and good nutrition to improve health and just feel better. With countless nutrition bars out there, how do you know which ones are the best? That is not an easy answer, but a little bit of research will help to make the process easier.

Who needs a nutrition bar? Nutrition bars are not just for those looking to lose weight or gain muscle; they offer a solution for heart health, diabetics, allergy-sensitive consumers, athletes and moms-on-the-go, just to mention a few. So, this means nutrition bars need to have all the right stuff in them to support all these different lifestyles. You will need to get the appropriate bar for you and your dietary restrictions so be sure to read the labels before you buy.

There are numerous factors to consider when reading the label of a nutrition bar. Good carbohydrates, healthy fats, the amount of fiber and good proteins are all things you will want to know about your nutrition bar.

Good carbohydrates are one of the most important factors in a good nutrition bar. Carbohydrates give our bodies energy to do our daily functions. They are composed of hydrogen, oxygen and carbon. In our bodies, carbohydrates are broken down into glucose which is, in turn, used to produce adenosine triphosphate or ATP which is used in the metabolic process. Carbohydrates are also important for muscles to function and retain their mass, especially during an extended period of exercise. The best nutrition bars will source their carbohydrates from natural foods without added sugar such as certain vegetables.

Healthy fats are important to our daily diets. Triglycerides and cholesterol not only store our energy but also give us insulation for our organs. Proteins wouldn’t be able to keep us moving without healthy fats. Cholesterol is what our cell walls are comprised of because cholesterol is not water-soluble. The cholesterol only allows fat-soluble molecules in and out of the cell.

The amount of fiber in your nutrition bar is extremely important. Fiber helps to move large molecules through our bodies. Most nutrition bars have proteins and carbohydrates to give energy, but they are difficult for our bodies to digest. Having at least 3 grams of fiber in the bar will enable the larger food molecules to move through our digestive tract with ease. You can find the amount of fiber listed in the nutrition facts section on the packaging.

Proteins are so vital to the function of our bodies. They are massive molecules that are extremely complex and perform most duties within the cell. They support tissues and organs but are also an essential part for the structure of these body parts. We need proteins to keep our blood sugars regulated for long periods of time as well.

When you want a nutrition bar that is dairy-free, soy-free, cholesterol-free and does not contain high fructose corn syrup, Nature’s Bakery Fig Bars are perfect. They are also kosher and vegan for those specific diets.

A nutrition bar that boosts energy and offers an incredible, 14 grams of protein is the Zone Perfect Nutrition Bar in fudge graham flavor. This bar is packed with vitamins and even offers antioxidants for boosting immunity. The flavor is similar to s’mores.

A popular choice among nutrition gurus is the KIND nutrition bars in Dark Chocolate Nuts & Sea Salt. This bar has only 5 grams of sugar but 6 grams of protein. Gluten-free and non-GMO in addition to 7 grams of fiber, makes these KIND bars a balanced option for a nutrition bar.

So when you want to find that happy medium between healthy and tasty, turn to these nutrition bars rather than your sugary, carb-filled, pantry snacks. You won’t regret it and they’ll make you feel great!
