Key ingredients for immune support

Thinking about taking AG1 for immune health?

You should always take a food-first approach to nutrition, but even healthy eaters can experience nutrient gaps due to differences in diet and food quality, genetics, gut health, and nutrient bioavailability. In an analysis of 157 participants across four clinical trials, 87% had at least one dietary nutrient gap, and most had four or more. AG1 Next Gen has been shown to help fill common nutritional gaps and complement participants’ day-to-day diets.

Here’s what’s in AG1:

• A daily dose of essential nutrients intended to support your body’s immune defense and keep you resilient, day in and day out
• Vitamin C and zinc to support immune health
• Superfoods and functional mushrooms for added whole food nutrients; these aid in filling nutrient gaps and replenishing a range of phytonutrients, promoting whole body health
• Probiotics, which promote gut health and immune function³

The combination of these nutrients, superfoods, and probiotics helps support the systems your body relies on to stay healthy and resilient. Consider AG1 a gentle way to help your immune system by ensuring it has the fuel and support it needs to function.*

AG1 Next Gen is well-researched

Most supplements aren’t clinically studied. AG1 Next Gen is different.

Our formula is shown to support your body’s various systems. It’s a low-effort, yet comprehensive way to get your body important vitamins, minerals, and probiotics—every day.

Our team has an ongoing commitment to discovery research, ensuring the benefits of our products are actually measurable. A few examples:

• 7 in 10 study participants had an increase in RBC folate, a 33% increase in Vitamin C levels after 3 months, and an average of over 10x increase in healthy bacteria in the gut.⁴
• After drinking AG1 Next Gen in addition to a healthy diet, study participants showed 94% of nutrient requirements met, as compared to only 71% of requirements met with diet alone.⁴

It’s essential to note that a drink of AG1 Next Gen is not a replacement for consistent consumption of the healthy, nutritious food your body requires. All studied improvements complement a healthy, nutrient-dense diet and other healthy habits.

How to incorporate AG1 into your daily routine

This one’s easy. It’s just one scoop, once a day. We recommend taking it first thing in the morning, but the timing can be flexible—just make it work for you so you can stick to it.

How to enjoy AG1:

• Add AG1 to your first glass of water in the morning.
• Mix it into a smoothie or add it to a protein shake.
• Enjoy it with lunch.
• Drink it before, during, or after a workout—though it’s not a protein shake or a traditional pre-workout fuel beverage.

As an all-in-one immune supplement, AG1 offers a convenient, once-daily way to help support immune health, gut health, and whole-body vitality—making it easier to build a strong nutritional foundation alongside a balanced diet and healthy lifestyle.
