Why International Bestselling Author Mike Matthews Created Atlas

Atlas is a 100% natural meal replacement supplement with high-quality whey and casein protein from small dairy farms in Ireland and nutritious, food-based carbs and fat.

Meal replacement and “weight gainer” supplements and protein and snack bars are quick, easy, and tasty, but they often contain . . .

  • Lower-quality forms of protein
  • Cheap refined sugars like maltodextrin, dextrose, and corn syrup derivatives
  • Low-grade fats like canola oil and creamers
  • Unwanted junk fillers and chemicals

While such supplements are convenient, many are inferior to whole foods, and that’s why we created Atlas.

It’s a naturally sweetened and flavored meal replacement supplement with exceptionally high-quality whey and casein protein from small, sustainable dairy farms in Ireland and nutritious, food-based carbohydrates and fats.

So, if you want a clean, all-natural, delicious meal replacement supplement with no chemical junk and cheap fillers . . . you want to try Atlas today.

You won’t be disappointed.

In fact, if you don’t absolutely love Atlas, just let us know and we’ll give you a full refund on the spot. No form or return necessary.

You really can’t lose, so order now, and try Atlas risk-free and see if it’s for you.

Ingredients (98.6 g per serving)

Whey Isolate & Micellar Casein Protein (38 g per serving)

When you’re considering buying a weight gainer or meal replacement supplement, the first thing you should look at is the types of protein it contains.

And what you’ll find in most cases is a blend of lower-quality forms of protein like milk protein, whey protein concentrate, and calcium caseinate.

The problem with these second-tier protein powders is they contain less protein and more carbs and fat than higher-quality options.

That’s why Atlas contains whey protein isolate and micellar casein, which are the highest grade fast- and slow-burning protein powders on the market.

Research suggests that a blend of fast- and slow-digesting proteins like this may be more conducive to muscle growth than either individually because it provides you with the immediate and powerful muscle-building stimulus of whey as well as the extended anti-catabolic effects of casein.[1][2][3][4]

Potato Starch & Oat Flour (51 g per serving)

Starch is a type of carbohydrate produced by most green plants as an energy store, and potato starch is exactly what it sounds like—starch extracted from potatoes.

We’ve included it in Atlas for a few reasons:

  1. Potatoes are one of the most nutritious carbohydrates you can eat, making potato starch a good source of vitamins, minerals, and fiber.
  2. It’s also a good source of resistant starch, which is a special type of starch found in certain foods that’s associated with various health benefits, including improving gut function, insulin sensitivity, and blood sugar control.[5][6][7]
  3. It’s readily absorbed and rich in glucose—a simple sugar that’s our bodies’ primary source of fuel—but doesn’t spike blood sugar levels, meaning it provides a boost of energy without a crash.

And why oat flour? It’s more nutritious than most other grains and also rich in a molecule known as beta-glucan, which is a carbohydrate that forms the cell walls of cereals, bacteria, and fungi and is known to lower cholesterol levels and support gut health.[8][9]

Also, similar to potato starch, oat flour is digested and processed slowly, preventing blood sugar spikes and crashes that come with most meal replacement and weight gainer supplements.

Tumeric Tumeric

Flaxseed & Coconut Oil (6 g per serving)

We chose flaxseed oil because it contains powerful antioxidants and alpha-linolenic acid, an omega-3 fatty acid that can provide the body with two others vital to its health: eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

We chose coconut oil because most of its fatty acid profile consists of medium-chain triglycerides, which are more readily converted into unusable energy than the types of triglycerides found in most foods and less readily stored as body fat.[10]

Boswellia Serrata plant Boswellia Serrata plant

21 Vitamins, Minerals, & Other Micronutrients (2,377.9 mg per serving)

We’ve fortified Atlas with 21 different micronutrients that many people are commonly deficient in and that are especially important for people who live physically active lifestyles.

These additions range from the basics like vitamin D, zinc, and magnesium, to the less commonly included, like vitamin K, inositol, and taurine.

Grapes and grape seeds Grapes and grape seeds

Digestive Enzymes & Probiotics (1,200 mg per serving)

Digestive enzymes are substances produced in the mouth, stomach, and intestines to help break food down into usable nutrients.

Probiotics are live bacteria and yeasts found naturally in your body that support gut function and health.

We’ve included two digestive enzymes in Atlas—bromelain and fungal lactase—because the more calories you eat, the more energy is needed to digest them, which ultimately means that the body needs to divert energy from and slow down other physiological processes, like muscle building.

We chose bromelain because it helps your body digest protein more efficiently, which aids in the muscle building processes, and fungal lactase because it assists in digesting the sugar in dairy (lactose), which can cause gastrointestinal stress in many people.

We’ve also included three probiotics most likely to benefit people with healthy guts—lactobacillus acidophilus, lactobacillus casei, and bifidobacterium lactis.

What’s more, these bacteria work best when they have a lot of food to “feed” them because no matter how well your gut functions or how many digestive enzymes you take, your body will never be able to fully digest and absorb every calorie that you eat.

A small portion of every meal will always make it to the large intestines undigested, where it can ferment and cause gassiness and discomfort and be eliminated as waste.

When you add probiotics into the mix, though, they’re able to eat up these remnants and turn them into various substances that benefit your digestive system and thus your entire body.

100% Naturally Sweetened & Flavored

No Artificial Food Dyes or Other Chemical Junk

100% Naturally Sweetened & Flavored

While artificial sweeteners may not be as dangerous as some people claim, studies suggest that regular consumption of these chemicals may indeed be harmful to our health.[11][12][13][14][15][16]

That’s why we use the natural sweeteners stevia and erythritol instead. Studies show that these ingredients are not only safe but can also confer several health benefits, including better insulin sensitivity, a lower cholesterol profile, improved blood glucose control, potential anti-cancer effects, lower blood pressure and inflammation levels, and more.[17][18][19][20]

No Artificial Food Dyes or Other Chemical Junk

As with artificial sweeteners, studies show that artificial food dyes may cause negative effects in some people, including gastrointestinal toxicity and behavioral disorders.[21][22][23][24][25]

That’s why we use natural coloring derived from fruits and other foods, as well as natural flavoring.
