According to Athletic Greens' official FAQ, AG1 can be mixed with various cold liquids, including milk and milk alternatives, as long as they are not hot or highly acidic. This offers flexibility beyond plain water for those looking to improve the taste or texture of their daily greens supplement.

Quick Summary

AG1 can be safely mixed with cold milk or milk alternatives like almond milk. This can be used in smoothies to improve the flavor and texture of the greens powder. The manufacturer recommends avoiding hot or highly acidic liquids to preserve ingredient integrity. Various mixing options are available to suit different dietary needs.

Key Points

Yes, you can add AG1 to milk: AG1 can be safely mixed with cold milk (dairy or non-dairy) without affecting its efficacy, according to Athletic Greens.
Avoid hot liquids: Never mix AG1 with hot milk or any other hot liquid, as heat can damage the probiotics and other sensitive ingredients.
Improve taste and texture: Mixing with milk or a creamy milk alternative can significantly improve the flavor and mouthfeel, masking the earthy taste often found in greens powders.
Best for smoothies: For a thicker, more satisfying drink, use a blender to mix AG1 with cold milk, fruit, and other ingredients to create a nutritious smoothie.
Use a shaker bottle: To prevent clumping, especially with thicker liquids like milk, use a high-quality shaker bottle with a wire whisk to ensure a smooth blend.
AG1 is dairy-free: The AG1 powder itself is dairy-free, meaning those with dairy allergies or sensitivities can safely mix it with dairy-free milk alternatives like oat or almond milk.
Lactose intolerance considerations: If you are lactose intolerant, stick to dairy-free milk substitutes to avoid potential stomach upset.
Optimal absorption: The manufacturer recommends taking AG1 on an empty stomach for optimal absorption, regardless of whether you mix it with water or milk.

Mixing AG1 with Milk: Is it a Good Idea?

For many, adding a scoop of AG1 to water is a standard morning ritual. However, some users find the earthy taste challenging and look for alternatives. Mixing AG1 with cold milk, or a milk substitute, is a popular choice for improving palatability and creating a more substantial drink, similar to a smoothie. AG1 is certified dairy-free, meaning it contains no dairy ingredients, and mixing it with dairy milk is a matter of personal preference and dietary needs, rather than product compatibility.

Potential Benefits of Mixing with Milk

Combining your greens powder with milk or a plant-based alternative can offer several advantages. First and foremost, it can significantly improve the texture and mask the earthy flavor, making the daily habit more enjoyable. For individuals looking to increase their protein or calorie intake, especially athletes, mixing with dairy milk can provide a good source of both. For those who prefer dairy-free options, blending AG1 with plant-based milks like almond or oat milk is a recommended method from the manufacturer to create a delicious and creamy smoothie.

Are There Any Concerns?

While generally safe, there are a few considerations when mixing AG1 with milk. Some individuals with sensitive digestive systems might experience minor discomfort, such as bloating or stomach upset, from the combination of ingredients like probiotics and milk. Another potential issue, particularly with thick dairy milk, is clumping. The powder may not dissolve as smoothly as it does in water, especially if not blended thoroughly. Using a shaker bottle with a wire whisk ball or a blender can help achieve a smoother consistency.

The Best Mixing Liquids for AG1

Beyond milk, many other liquids can be used to customize your AG1 experience. The key is to avoid hot liquids, as the heat can damage the integrity of heat-sensitive ingredients like probiotics. Highly acidic beverages, which could potentially reduce the alkalinity, should also be avoided.

Alternative AG1 Recipes and Pairings

For Smoothies: Add AG1, almond milk, half a banana, and some frozen berries to a blender for a nutritious and delicious smoothie.
With Juice: Apple juice can effectively mask the taste while adding a touch of natural sweetness.
The Simple Route: Plain, cold water remains the most straightforward method, and AG1 is formulated to taste pleasant with it, featuring natural notes of pineapple and vanilla.

In short, adding AG1 to milk is a perfectly acceptable and safe way to consume the supplement, particularly if you're looking for a better taste and texture. The manufacturer even provides recipes using milk alternatives, such as almond milk, in its official FAQ. However, it's worth noting that using dairy milk will alter the supplement's nutritional profile by adding calories and protein. If you are lactose intolerant, stick to a dairy-free milk alternative to avoid potential stomach issues. No matter which liquid you choose, remember to always use cold temperatures to preserve the probiotics and other sensitive ingredients. Experiment with different combinations to find the one that best fits your dietary needs and taste preferences.

AG1 and Dairy-Free Alternatives

AG1 is a dairy-free product, making it suitable for those with dairy allergies or who follow vegan or dairy-free diets. When mixing with milk alternatives, you can maintain a dairy-free drink. For instance, almond, oat, coconut, or soy milk are all suitable options that provide a creamy base without dairy. Always check the ingredient list of your chosen milk alternative to ensure it aligns with your specific dietary requirements.

The Best Time to Drink AG1 with Milk

While AG1 can be consumed at any time, many users prefer taking it in the morning on an empty stomach to optimize absorption. Drinking it with milk can make it more filling, which is ideal if you want a complete morning drink to hold you over until your first meal. For best results, use cold liquid and consume immediately after mixing to avoid potential clumping and to preserve the supplement's freshness.
