AG1 Expert Review: Is AG1 a Scam?
Like many other supplements, AG1 sometimes sparks questions and debate online – and that’s a good thing. After all, when it’s something you take every day, you want to be sure it’s not only safe and high quality, but also genuinely beneficial.
That’s why Dr Georg Abel, a PhD nutrition scientist, takes a closer look at some of the most common questions, misconceptions and critiques about AG1 found online.
“No one needs supplements.”
Can’t you just eat a balanced diet?
Dr Georg Abel says: Absolutely – a varied, balanced diet is the foundation of good health. Supplements, as the name suggests, are designed to supplement your diet. Whether someone needs or chooses to use them depends on individual lifestyle and circumstances.
But to claim that no one needs supplements isn’t accurate. Research shows that the nutrient content of many foods has decreased in recent decades – for example, minerals like zinc, iron, and magnesium. Nutrient levels vary depending on soil quality, storage, and preparation methods such as cooking.
Supplements like AG1 can help support a controlled and health-focused intake of essential nutrients – especially when diet alone doesn’t always provide optimal amounts.
Are they essential for survival? Usually not – and you shouldn’t be told otherwise.
“The ingredients in AG1 are overdosed.”
267% of your daily Vitamin E needs – isn’t that dangerous?
Dr Georg Abel says: No need to worry – none of the ingredients in AG1 are overdosed. This is a common misunderstanding. When people talk about “overdosing” in supplements, they often confuse two very different concepts:
Nutrient Reference Values (NRVs)
These are the percentages you see on product labels. They indicate the daily amount of vitamins or minerals the average healthy adult needs to meet their basic requirements. They also serve as a guideline to prevent deficiencies and to show whether a product contains meaningful levels of a nutrient. Only nutrients that reach at least 15% of the NRV can be listed on a label or linked to health benefits.
Tolerable Upper Intake Levels (ULs)
This is the maximum daily intake that can be consumed safely over time – not shown on labels, but defined by the European Food Safety Authority (EFSA).
Scientific research shows that the NRV does not represent the optimal intake level. The amount that’s physiologically beneficial often lies above the NRV but below the upper safe limit.
Example: Vitamin E
AG1 contains 32 mg of Vitamin E per serving – that’s 267% of the NRV, but still well below the EFSA’s safe upper limit of 300 mg.
So while it’s more than the minimum daily requirement, it’s comfortably within a healthy and safe range.

“AG1 is expensive – it’s just overpriced urine.”
Couldn’t I just take a multivitamin instead?
Dr Georg Abel says: Price is one of the most common points of criticism – and it’s understandable. AG1 is positioned at the higher end of the market, which can cause some scepticism at first glance. But cost should always be viewed in relation to what you’re getting: premium-quality ingredients, continuous research and product development, and a uniquely comprehensive nutrient profile. Those things come at a price.
And as for the idea that you’re “just paying for expensive urine” – that’s not how nutrient metabolism works. The body absorbs and uses what it needs, while excreting what’s no longer required. That’s how a healthy system functions. A well-formulated supplement isn’t about excess – it’s about consistency, convenience, and ensuring your body gets what it needs, every single day.
AG1 has clinically studied the bioavailability of their ingredients:
AG1 helps improve key nutrient levels within 3 months.ᵃ
AG1 decreases Homocystein levels.ᵃ
WHY THIS MATTERS
Homocysteine is an indicator of sufficient supply of B vitamins. A low-normal homocysteine level suggests a good B6, B12, and folate status – nutrients that among others support the homocystein metabolism. A functioning homocysteine metabolism prevents the accumulation of intracellular homocysteine and subsequent export into the blood, where it can contribute to oxidative stress.
AG1 increases vitamin C levels.ᵃ
WHY THIS MATTERS
Representing antioxidants in AG1, vitamin C plays an important role in defending the body against oxidative stress³ and supporting immune function¹. As a powerful antioxidant, it’s essential to a wide range of physiological, psychological and cellular functions¹²⁴.

AG1 is clinically shown to enrich the gut microbiome.ᵃ⁻ᶜ
Over 10x average increase in friendly bacteria in the gut.ᵃ⁻ᶜ
WHY THIS MATTERS
These good bacteria live in the gut as part of a healthy microbiome.

b. In a double-blind, randomised, placebo-controlled 2-week cross-over clinical trial assessing microbiome shifts in 20 active adults ages 19-37.
c. In a double-blind, randomised, placebo-controlled 2-week cross-over clinical trial assessing microbiome shifts of 24 healthy adults with occasional GI distress ages 26-59.
Key nutrients in AG1 were shown to be quickly and easily absorbed into the body.ᵈ
Thiamine levels were significantly increased within 30 minutes of drinking AG1.ᵈ
WHY THIS MATTERS
AG1 delivers key nutrients like thiamine, biotin, riboflavin, niacin, vitamin C, zinc and folate – in bioavailable forms the body can easily and readily utilize, maximizing their potential benefits.
d. In a double-blind, randomised, placebo-controlled cross-over clinical trial assessing bioavailability in 16 healthy adults ages 18-42 over the course of 8 hours.
The studies were conducted on a similar version of AG1's continually evolving formulation. The transferability of the study results is ensured because of comparable ingredients and amounts.
“AG1 doesn’t taste good.”
A green powder? Surely it must taste just as it looks – very green.
Dr Georg Abel says: It’s understandable that people might doubt the taste of something so green. But AG1 is actually described by most users as fresh and fruity, with notes of pineapple and vanilla. Unlike many other supplements, it contains no artificial flavours or added sugar.
Personally, I think it tastes pretty good. But the only way to know for sure is to try it yourself. And if you’re not convinced – there’s always the 30-day money-back guarantee.
TL;DR
What Does an Expert Think of AG1?
- As with any supplement, there are both positive and critical opinions about AG1. Some question the price or the taste, while others praise the high ingredient quality and how it makes them feel.
- If you’re looking for a high-quality, effective supplement that delivers a broad range of bioavailable nutrients, AG1 is a strong choice.
- As always: try it yourself and see if AG1 fits your daily routine – and speak with your doctor if you’re unsure.
