As a global nutrition company, we’re all about providing our customers with daily balanced nutrition. But meeting your nutritional needs every day can sometimes be difficult to put into practice. Our lives are so busy with work, school, or family commitments that planning and preparing healthy meals and snacks is often an afterthought.

Healthy lifestyles are built on balanced nutrition, so we developed our signature protein shake product, Herbalife Nutrition Formula 1 Healthy Meal Nutritional Shake Mix.

Formula 1 is a delicious, easy-to-make shake mix that provides an ideal balance of protein, fiber, vitamins, and minerals. Around the world, more than five million Formula 1 shakes are consumed every day.

Formula 1 protein shakes can be used in a number of ways, such as:

What Is Formula 1?

Formula 1 is a complete, convenient meal that provides the nutrients your body needs. Its plant-based protein formula was developed by nutritionists and food scientists and is rooted in the latest research showing the efficacy of meal replacements, along with diet and exercise, as a solution for achieving a healthy weight**. According to a systematic review and meta-analysis of 14 studies, the University of Oxford found that programs incorporating meal replacements led to greater weight loss compared to alternative diets.

But a Formula 1 shake can be a part of anyone’s balanced daily regimen. Whether you’re focused on shedding pounds, building up muscle, maintaining a good diet, or all of the above, Formula 1 is a key addition to your routine of smarter eating and regular exercise.

A Formula 1 shake, when made with 8 fluid ounces of nonfat milk or soy milk contains:

A Formula 1 for Everyone

Formula 1 is built on sound science and, as millions of customers can attest to, the varieties of flavors are delicious. In North America, we have flavors such as Cookies ‘n Cream, Wild Berry, Dulce de Leche, Dutch Chocolate, Pumpkin Spice, and more. My personal favorite is Banana Caramel.

In other markets, we’ve developed region-specific flavors to help customers around the world better achieve their nutrition goals. Examples include Kulfi Formula 1 in India, Matcha and Red Bean Formula 1 in China, Cantaloupe Formula 1 in Russia, and Chocolate Hazelnut Formula 1 in South and Central America.

For individuals with specific dietary restrictions or allergies, we also created Formula 1 versions to meet the needs of those who follow vegetarian, gluten-free, kosher, vegan, or soy-free diets. For instance, our Formula 1 Select line is a gluten-free, AVA certified vegetarian blend made with pea, quinoa, and rice proteins, non-GM ingredients and is certified kosher. Similarly, Tri Blend Select, available in certain European markets, is our first 100 percent vegan protein shake made with pea, quinoa, and flax seeds.

Formula 1 and Its Glycemic Index Value

The Glycemic Index (GI) is a method that quantifies the effects of carbohydrate-rich foods on the sugar levels in your bloodstream. When these foods are digested and absorbed, the end result is a rise in blood sugar (or, blood glucose), which serves as the primary fuel for your muscles and brain. Since they don’t all affect blood sugar the same way, the GI is used to rank foods according to how much – and how rapidly – they cause blood sugar to rise after they’re eaten.

Many high GI carbohydrates are those that are highly refined and readily digested and absorbed – like white bread, white rice, pasta or sugary foods – and have GI values of 70 and above. These foods tend to cause quick spikes in the blood sugar. But these spikes are often followed by steep declines, which can lead to cravings for more high GI foods to bring blood sugar levels back up and maintain physical and mental energy. The end result may be a which can lead to a “roller coaster” of blood sugar highs and lows throughout the day.

Low GI foods, with a GI of 55 or less, include non-starchy vegetables, whole grains, beans and lentils, apples, berries, and oranges. They release carbohydrates more slowly into the bloodstream, so the rise in blood sugar is more modest and energy levels are more sustained. In addition, several flavors of Formula 1 carry the Low Glycemic Index symbol and are certified by the Glycemic Index Foundation. For individuals who follow a carbohydrate-restricted diet, this information can be helpful in meal planning.

The Different Ways You Can Customize Your F1 Shake

Aside from the vast variety of flavors, a Formula 1 shake can be tailored to meet your unique nutritional needs, tastes, or preferences.

What type of milk should you use for Formula 1?

Label directions suggest blending Formula 1 with milk or soy milk, as they complement the protein in the shake mix and also provide additional vitamins and minerals, making the finished shake nutritionally complete. 

There are many milk alternatives available other than soy, but they can vary greatly in calorie and protein content. To maximize protein, your best bet is a pea-based milk – most brands match the 8 grams of protein you get in a cup of dairy or soy milk. Most nut-based milks don’t offer much protein – only 1 gram or so per cup – so, if you use them, you’ll want to add more protein to your shake to match the 17 grams you would get when making the shake according to label directions.

Ways to Customize Your Shake

Add More Protein

Even though Formula 1 is already formulated with protein, you might want to include more if your protein needs are high. You can add plain protein powder, such as Herbalife Nutrition Personalized Protein Powder, or add low-fat cottage cheese, yogurt, ricotta cheese, or silken tofu to boost protein content.

For a higher protein shake, many of our customers prefer a water-based blend made with a serving of Herbalife Nutrition Formula 1 and a serving of our Protein Drink Mix – a combination that serves up 24 grams of protein. With the many flavors of both Formula 1 and Protein Drink Mix to choose from, the flavor combinations are nearly endless. If you’re interested in post-workout and recovery products, you can also look into our dedicated sports nutrition line, Herbalife24.

Add Fruits and Vegetables

Adding fruits and vegetables to your Formula 1 protein shake is an easy way to get more servings of these healthy foods in your daily diet. Frozen fruits and vegetables are convenient, and they give your protein shakes a thicker texture. Experiment with different fruits and vegetables (you might start with sweeter veggies like carrots or butternut squash) and try different combinations – like pineapple with carrot, or banana with butternut squash.

When you’re feeling a little bolder, try adding more unusual ingredients to your shake – like baby spinach leaves or beets.

Add Beneficial Fats

Seeds like flax, hemp, chia or sunflower add a bit of texture to your shake, and give a little boost of minerals (especially copper and zinc) and omega-3 fatty acids. Nut butters – such as almond, walnut or pistachio – also contribute zinc and copper, along with some protein and fiber, too.

Add Fiber

Most people don’t eat as much fiber as they should, so try adding high-fiber foods to your Formula 1 shakes.  Aside from fruits and vegetables, rolled oats, bran, or seeds such as sunflower, flax or chia seeds all contribute fiber.

Another great shake addition is Herbalife Nutrition Active Fiber Complex: a blend of soluble and insoluble fibers with 5 grams of fiber per serving.

Add Herbs and Spices

Try a dash of sweet cinnamon, nutmeg, allspice or clove, or add some spicy heat with ginger or even a dash of white pepper. Since they’re plant products, spices also contribute phytonutrients and antioxidants. Herbs may not be something you’ve thought about adding to your shake, but there are plenty of herbs that work really well, such as mint, rosemary, thyme or basil.

Add Extracts and Zest

A little fresh lemon or orange zest adds a bright, fresh flavor to your shake, and there are some healthy oils in citrus peel, too. I also like to keep all kinds of extracts on hand – like pure vanilla, almond, coconut and peppermint for an extra flavor boost.

Add Ingredients That Support Digestive Health

Herbal Aloe Concentrate adds a mild sweet flavor to your shake and helps support nutrient absorption in your digestive tract. Yogurt contains probiotics – the “good” bacteria that help support digestive health. Ginger and peppermint are both known to aid the digestive process. Chia seeds are a very rich source of soluble fiber, which supports the growth of the good bacteria in your intestines.

Add More Calories

If your calorie needs are high, you can add rolled oats, nuts, nut butter, avocado, or dried fruit to boost the calorie content of your shake.

Add Ice to Your Protein Shake.

Ice makes a nice addition to a shake because it thickens up the liquid. Ice also adds volume to your shake, so it increases the portion size without adding calories. This is a great trick for those who are watching their weight.

Our daily routine can be complicated, but balanced nutrition shouldn’t be. Each meal and snack provides an opportunity to improve your nutrition and ensure you are ingesting calories packed with the nutrients needed to replenish and rebuild.  Formula 1 can be the foundation for a healthy diet and lifestyle, and with so many options for making delicious shakes, everyone can find a shake that works for them.

*Clinical studies on U.S. Formula 1 (one study) and on similar products show that Formula 1 shakes taken twice a day as part of a reduced-calorie diet help people lose weight.
**Studies still have to be conducted to determine the expected results of weight-loss or maintenance programs that use exclusively Herbalife Nutrition products.
