As recently as the 1990s the few doctors and nutritionists that had heard of gluten only knew it to be the result of a chemical bond between the molecules of glutenin and gliadin that allowed things like pizza dough to have its sticky character.
Today, we know that about 1 percent of the population suffers from celiac disease which is an intestinal condition triggered by exposure to this ingredient.
But many health professionals believe its danger do not stop there. As such, gluten free foods and supplements - including the protein powders profiled below - have become a hot item and there are a growing number of people who consume these types of products.
Below we'll take a close look at the 5 best gluten free supplements on the market today.

Vega Sport is more than just one of the best vegan protein powders on the market, it’s also the best supplement of its kind on the market. Vega Sport achieves that impressive double play by paying attention to the details.
Their gluten free supplement is carefully formulated with pre and probiotics to create a healthy digestive environment, is derived from not one but five different plant-based sources and is chock-full of the branched chain amino acids your body needs in order to recover from a vigorous workout.

Toss in the fact that it’s more affordable and it creates tasty gluten free protein drinks than most other products in the market.
2. Orgain Organic Supplement
Orgain Organic Gluten Free Protein Powder is produced in a certified organic facility and is perfect for vegans or vegetarians. On top of that it just happens to be one of the highest quality supplements you can buy.
Orgain makes sure every ingredient in their plant-based product meets their rigorous quality control and dietary standards. They never use genetically modified organisms to try and prop up their protein powder because, frankly, it doesn't need propping up.
In many ways, Orgain Organic sets the bar for purity and efficacy. The protein here is derived from brown rice and hemp which is known to be rich in iron, calcium and magnesium and low in carbs and calories.
In addition, there's no sugar added, no artificial preservatives, no soy and it comes in a variety of natural flavors. It's going to cost you more, but it's worth the stretch in making the best gluten free protein shakes.
3. Isopure Zero Carb
Isopure Zero Carb is a great way to power up your keto diet and to derive enhanced results from your time in the gym. Isopure is 100% gluten free whey protein.
It is extremely effective in delivering nutrients to overworked muscles post-workout, or to provide the strength and endurance you'll need prior to your workout.
Because Isopure is whey protein, it's not going to be for everyone, but if you are not lactose intolerant or vegan then Isopure will help you achieve the lean, muscular physique you've been yearning for.
Isopure is available in a variety of flavors, so there's bound to be one that's perfect for you.
Have your gluten free meal replacement shakes first thing in the morning to jump-start your day or after your workout to activate the process of recovery.
4. Muscle Milk Protein Powder
Each serving of Muscle Milk contains 32 grams of protein and is low in calories and rich in calcium, iron, and magnesium. It is also loaded with vitamins A, C and D while being completely devoid of genetically modified organisms.
Each Muscle Milk gluten free protein shake provides the full array of other nutrients you need when you're trying to establish new personal bests, and it does so without bombarding you with artificial flavor enhancers, preservatives or colors.
Mix Muscle Milk with water or milk or add it to your pancake or muffin batter. If you’ve been experiencing a lack of energy in the gym or protracted recovery times after strenuous workouts, this will fill the nutritional gap and get you back on the road to help you achieve a leaner, stronger you.
This product is really one of the best gluten free protein powders in the market today.
5. PlantFusion Complete Protein
Plant-based protein is known to be more easily digestible which means you don't usually need as much to get the results you're after.
That's good news because often you have to consume ridiculous amounts of animal-based supplement to see any benefit and this means thick, chalky healthy shakes that are tough to choke down.
With PlantFusion, you get all the nutrients you need and none of the soy, eggs, fish, nuts or lactose you don't need. And because you don't need so much, your gluten free protein shakes are a joy instead of a slog.
Each serving provides 21 grams of efficacious, gluten free plant-based protein, a scant 120 calories, and zero saturated fats.
PlantFusion products are also hypoallergenic, and there isn't a genetically modified organism anywhere to be found in their state-of-the-art production facility.
Is Whey Gluten Free?
Whether in concentrate, isolate or hydrolysate form, whey itself does not contain this ingredient. As such if you suffer from celiac disease, consuming this type of protein should be a safe thing to do. 
However, and this is important, there are some types of supposedly gluten free whey protein powder that include additives in their formulation which do contain it.
Glutamine, for instance, is a fairly common protein powder additive that is derived from wheat just like gluten and which many health professionals say should be avoided if you suffer from its intolerance.
Why is It Added to Some Protein Powders?
As we said at the outset, gluten has the ability to, among other things, cause pizza dough to bond and become malleable. Which is one reason it’s found in so many different products. It’s also for that reason that it is sometimes added to protein powder.
Not that it’s going to turn protein powder into pizza dough but it improves the texture, which makes for smoother gluten free meal replacement shakes. In addition, peptide-bound glutamine is sometimes added to the supplement to cover for a loss of amino acids during processing.
Choosing the Best Gluten Free Supplement
As you have likely deduced by now, this can be a tricky ingredient to track down. The fact that protein powders are not subject to FDA regulations only complicates the matter, allowing companies to claim their protein is gluten free while at the same time they add glutamine to their powder to make it more agreeable.
As such, when choosing a supplement, it's imperative that you read labels carefully and thoroughly.
Should you see any of the following on the ingredient list you'll want to take a pass, especially if you have celiac disease:
