Q: What is whey protein isolate?
A: Whey protein isolate, the primary source of protein in Primal Fuel, is the gold standard in protein powders, because it has the highest bioavailability of any form of protein. This means that it’s one of the easiest types of protein for your body to use. It is derived from milk, but retains very little lactose or other milk proteins, which makes it easier to tolerate than other dairy supplements. So, it is derived from dairy, but it is casein free. If people have difficulty digesting dairy, it is typically because of the casein content. Furthermore, many studies have demonstrated the various beneficial health properties of this particular protein, such as improved digestion and a stronger immune system.
Our Fuel is the only protein on the market that derives its fat from coconut milk, which is considered one of the most heart-healthy fats. It is grain free and soy free, which is important to us as we believe a grain- and legume-free diet is the most appropriate diet for our genetic disposition.
Finally, our protein powder contains inulin from Jerusalem artichoke and kelp extract, a great prebiotic that helps aid in digestion and immune function. Obviously if your goal is to be a raw foodist our protein does not fall within this framework. It really comes down to your belief system as to what type of diet is the best for your genetic expression. Our philosophy is founded on the principles of ancestral health and the idea that our bodies thrive on a diet most closely related to that of our Primal ancestors.
Q: Is the whey from grass-fed cows?
Grass-fed animal fat is better. Grass-fed meat is better. Grass-fed dairy is definitely better. But grass-fed whey isolate? It's actually unnecessary. Why? Well, let’s look at the commonly cited reasons for preferring grass-fed animal products to grain-fed animal products. Grass-fed has better fatty acids, more omega-3, and more CLA. Whey isolate contains no fat. Grass-fed has a better micronutrient profile, more minerals, and more vitamins. Whey isolate contains neither minerals nor vitamins. Grass-fed has a better taste. Some say it’s “gamey.” Whey isolate has no flavor, so “better” doesn’t enter the equation. When you don't keep the fat in your protein powder, it makes no difference if the cows from which it comes are grass fed or not. Grass feeding only affects fat profile, not protein content or amino acid profile. Grass-fed's benefits are mostly in the healthy fats and WPI (whey) has very low fat (it's supposed to be a source of protein), so it’s not really cost effective to source the whey from grass fed cows.
Q: What is the amino acid breakdown?
Alanine: 970 mg , Arginine: 400 mg, Aspartic Acid: 2170 mg, Glutamic Acid: 3440 mg Glycine: 310 mg, Histidine: 380 mg, Isoleucine: 1310 mg, Leucine: 2040 mg, Lysine: 600 mg, Methionine: 890 mg, Phenylalanine: 1150 mg, Proline: 1420 mg, Serine: 970 mg, Threonine: 1460 mg, Tryptophan: 350 mg, Valine: 1150 mg *per serving (20 g of protein)
The amino acids you see on the side of Muscle Milk are just as you thought, simply the amino acid profile from the casein and whey protein sources. There are no added aminos. Primal Fuel has a similar amino acid content breakdown. The difference is that we don't use casein as a protein source (it causes problems with some people) and we don't use canola oil, sunflower oil, or any other high-omega-6 vegetable oils. In fact, we avoid those like the plague (even more than sugar). Instead, our fat comes from coconut milk, the healthiest source of fats on the planet.
Q: What are prebiotics?
A: Prebiotics are food for the good bacteria that inhabit your gut. Prebiotics encourage these good bacteria to survive and thrive. Primal Fuel prebiotics come in the form of all-natural soluble chicory.
Q: For how long does Primal Fuel curb hunger?
A: One Primal Fuel shake can curb hunger for up to three to five hours after consumption. It’s not meant to replace all your meals (you still need to eat a balanced diet to achieve optimal health and weight loss), but it curbs hunger without adding lots of calories, which makes you more likely to eat responsibly at other meals.
Q: What are the "natural flavors" made of?
A: Our natural flavors are true to their name. They’re a proprietary blend of natural cocoa powder, natural chocolate fudge, and natural vanilla bean—nothing tricky or artificial!
Q: The chocolate fuel contains cocoa powder, does that mean there is caffeine?
A: A tablespoon of cocoa powder has about 12 milligrams of caffeine - not much, but it can affect an individual who is sensitive to it. A serving of Primal Fuel has even less than a tablespoon of cocoa powder, however, if it keeps you up, you may want to have your shakes earlier in the day.
Q: Your product label says Primal Fuel contains milk, soy and tree nuts. What gives?
A: We do not add soy to our Primal Fuel. There is no soy in the product. One of the natural flavors (2% of the formula) has a tiny bit of soy lecithin (2% of that), which is a phospholipid containing none of the soy protein from which it was derived, as an emulsifier. Labeling laws require that we have a disclosure on the ingredient panel for those who are extremely sensitive to certain allergens regardless of whether they are in the product as long as the factory where the product was made also processes these other allergens (such as soy, peanuts, milk, etc.).
Q: What is your filtration process?
A: Our filtration produces all natural protein powder without any added chemicals. There are differences between whey protein isolate and whey protein concentrate. Whey protein isolate has a higher protein content and is lower in carbohydrates, lactose, and fat. But it is typically more expensive due to the additional manufacturing process it undergoes. Micro Filtration techniques use low temperatures to allow production of very high protein contents (>90%), the retention of important sub-fractions, extremely low fat and lactose contents, and virtually no undenatured proteins.
Q: Is Primal Fuel screened for heavy metals?
A: It's not something we routinely test, however, we work with a Canadian manufacturer with as strict, if not stricter standards than US manufacturers. All of our ingredient suppliers go through a rigorous approval process because the facility is SQF certified.
Q: How often should I consume Primal Fuel?
A: Many people use Primal Fuel as a breakfast shake to start the day or to replace a meal with a low-calorie, high-protein, moderate-fat option. Others use it as a quick primal-friendly snack when better snack choices are unavailable or unappealing. Some find it's a great way to add more protein and healthy fat to an existing small meal. So the frequency in which you use it will depend on how you use it.
Q: What is the shelf life?
A: The Shelf life would be no less than 9 months from being opened. Each canister has an expiration date labeled on the package.
