The market for greens powders is booming, with products like AG1, previously known as Athletic Greens, gaining immense popularity through endorsements and slick marketing. Positioned as a comprehensive nutritional supplement, AG1 contains a blend of vitamins, minerals, superfoods, probiotics, and adaptogens. However, while the product suggests broad wellness benefits, its specific impact on markers like cholesterol is less clear and not explicitly claimed by the company. The effectiveness of AG1 for heart health is complex and depends on a nuanced understanding of its ingredients and the limitations of its proprietary formula.
The Science Behind AG1's Ingredients and Cholesterol
AG1 is a composite of many different ingredients, some of which have been studied individually for their effects on cholesterol. While these components show promise in isolation, their efficacy within the AG1 blend is uncertain.
Probiotics and Gut Health
AG1 contains a blend of probiotics, including Lactobacillus acidophilus and Bifidobacterium bifidum. Extensive research indicates that certain probiotic strains can produce short-chain fatty acids (SCFAs) that block cholesterol-producing enzymes in the liver. Probiotics can also encourage the body to use up circulating cholesterol to create bile acids, further reducing blood cholesterol levels. A 2018 meta-analysis found that probiotics could reduce total cholesterol, with some specific strains potentially offering significant benefits. However, it is crucial to note that this research was on probiotics generally, not specifically on the AG1 product, and the impact depends on the specific probiotic strains and their quantity.
Spirulina, Chlorella, and Other Superfoods
The 'superfood' complex in AG1 includes ingredients like spirulina and chlorella, which have been individually studied for their potential to lower blood pressure and cholesterol. Cocoa, another ingredient, has also been linked to improved cholesterol levels. However, the amounts of these ingredients within AG1's proprietary blend are not disclosed. This lack of transparency means it is impossible to know if the concentration is high enough to produce a therapeutic effect, as seen in clinical studies. For example, studies on chlorella often use doses far higher than what is likely present in AG1 to observe an effect.
The Issue of Proprietary Blends
AG1 lists its ingredients in 'proprietary blends,' meaning the precise amounts of each component are not disclosed to the consumer. This is a major hurdle for anyone trying to determine if the product is effective for a specific health goal like lowering cholesterol. Without knowing the dosage of key compounds like probiotics or spirulina, any potential health claims, especially regarding clinical outcomes, are speculative. This is why many health professionals caution that AG1 should not be seen as a targeted medical treatment.
Comparison: AG1 vs. Other Cholesterol-Lowering Strategies
When considering how to manage cholesterol, it is helpful to compare AG1 with other, more scientifically validated methods. AG1 can be part of a healthy lifestyle, but it is not a substitute for proven approaches.
| Feature | AG1 Greens Powder | Heart-Healthy Diet & Exercise | Proven Supplements (e.g., Psyllium) |
|---|---|---|---|
| Scientific Evidence | Indirect and circumstantial, based on individual ingredients; no specific clinical trials on AG1's formula for cholesterol. | Strong, long-standing, and evidence-based for significant cholesterol reduction. | Varies by supplement, but some like psyllium, phytosterols, and specific omega-3s have supporting research. |
| Mechanism of Action | Hypothetical, relying on probiotic and superfood content to influence gut health and metabolism. | Multifactorial: increasing soluble fiber, healthy fats, and physical activity to block absorption and improve lipid profiles. | Targeted actions, such as psyllium binding to cholesterol in the gut or phytosterols blocking its absorption. |
| Transparency | Lacks transparency due to proprietary blends, so effective doses are unknown. | Highly transparent, with clear dietary guidelines on what to eat and what to limit. | Clear dosage information, often standardized and regulated. |
| Primary Role | Foundational nutritional support; a way to fill potential nutrient gaps. | First-line, most effective strategy for lifestyle-based cholesterol management. | Adjunctive therapy; a secondary tool to use alongside diet and exercise, often under medical guidance. |
The Verdict: Can AG1 Be Part of a Cholesterol-Lowering Plan?
For someone seeking a simple, proven way to lower their cholesterol, AG1 is not the answer. There is insufficient high-quality clinical evidence to suggest that AG1, as a complete formulation, can reliably or significantly reduce cholesterol levels. While it contains ingredients that, in isolation, have shown potential, the proprietary nature of the blend and the lack of specific studies on the product itself mean its effects on cholesterol are, at best, a secondary and uncertain benefit.
Instead of viewing AG1 as a targeted treatment, it is more accurately seen as a dietary supplement that can provide a broad spectrum of nutrients to fill potential gaps in a person's diet. For those concerned about cholesterol, a comprehensive, evidence-based strategy involving diet, exercise, and medical supervision is paramount.
Best Practices for Lowering Cholesterol Naturally
Adopting a holistic approach is the most effective way to manage and lower cholesterol levels. A greens powder like AG1 can be a complementary tool, but these foundational strategies are essential.
- Prioritize Soluble Fiber: Increase your intake of soluble fiber, which binds to cholesterol and removes it from the body. Excellent sources include oats, barley, apples, citrus fruits, and legumes.
- Choose Healthy Fats: Replace unhealthy saturated and trans fats with monounsaturated and polyunsaturated fats. Opt for healthy cooking oils like olive oil and incorporate foods rich in omega-3 fatty acids, such as salmon and flaxseed.
- Eat More Whole Foods: Focus on a diet rich in fruits, vegetables, whole grains, and lean proteins, limiting processed foods, red meat, and sugary snacks.
- Regular Exercise: Engage in regular physical activity. The American Heart Association recommends at least 150 minutes of moderate-intensity exercise per week.
- Maintain a Healthy Weight: Losing excess weight, especially around the midsection, can have a positive impact on cholesterol levels.
- Consider Proven Supplements: If needed, discuss with your doctor whether supplements like psyllium husk, phytosterols, or red yeast rice might be appropriate additions to your plan. Be aware of potential risks and side effects.

In conclusion, while AG1 offers a host of nutrients, it is not a proven cholesterol-lowering solution. The most reliable path to better heart health is through consistent, evidence-based dietary and lifestyle modifications under the guidance of a healthcare professional. Any potential benefits from AG1 for cholesterol are minor and unverified compared to these foundational strategies.
