Why Does AG1® Have a Lead Warning?

Why Does AG1® Have a Lead Warning?
By Previnex®

Finding a green powder supplement that’s made with high-quality, pharmaceutical-grade, organic ingredients is crucial. There are farming, manufacturing, and testing standards that go into how a greens powder supplement is put out into the world, and if companies and products do not have the correct standards, it can be detrimental to your health. Some companies put lead warnings on their products, and there’s a good reason for it. Let’s dive in. 


Does AG1® Contain Lead? 

Yes, AG1® does report that their products contain trace amounts of lead, but the levels are within the regulatory limits and deemed safe for consumption. The company states that each batch of AG1® is third-party tested to ensure that the levels of heavy metals are below the USP (United States Pharmacopeia) guidelines and the NSF Certified for Sport® guidelines. There is a threshold laid out by USP for the level of heavy metals in supplements, vitamins, and other food ingredients. 


Heavy metals such as lead, arsenic, cadmium, and mercury can enter crops through soil, water, or air pollution. This causes the fruits, vegetables, roots, and herbs to absorb those heavy metal toxins. Heavy metals can also be introduced to food during the manufacturing process, depending on the machinery and safety precautions (or lack thereof). 


AG1® details their sourcing and ingredient details on their website, as well as their third-party testing standards. 


Why Does AG1® Have a Prop 65 Warning? 

AG1® has a Prop 65 warning because they sell products in and source ingredients from California and their products have lead amounts that exceed 0.5 mcg/day (which triggers the Prop 65 warning). All products with more than 0.5 mcg/day of lead must have a Prop 65 warning, regardless of where they are manufactured or come from.. 


Prop 65 is a law in California that requires businesses to provide warnings before customers are exposed to any of the chemicals on California’s Prop 65 list. The law has been in place since 1986, and is known officially as the Safe Drinking Water and Toxic Enforcement Act of 1986.


The Prop 65 warning simply advises customers that they may be exposed to chemicals that can contribute to an overall lifetime risk of cancer, birth defects, or other reproductive harm. It does not mean that there are dangerous levels of those toxins, just that there is a chance for exposure. This is where digging into a company’s sourcing, manufacturing, and testing processes is crucial! If a company does not have high-quality standards and practices in place, you are increasing your risk of exposure to these toxins exponentially. 


Are There Bad Ingredients in AG1®? 

AG1® claims to source their ingredients “from quality partners for absorption, potency, and nutrient density to deliver the Foundational Nutrition your body needs.” One pack/scoop of AG1® contains: 

  • Vitamin A (as beta-carotene)

  • Vitamin C (as ascorbic acid) 

  • Vitamin E (as mixed tocopherols)

  • Thiamin (Vitamin B1, as thiamine hydrochloride)

  • Riboflavin (Vitamin B2)

  • Niacin (as nicotinic acid, niacinamide)

  • Vitamin B6 (as pyridoxal-5-phosphate - P5P)

  • Folate (as 5-MTHF)

  • Vitamin B12 (as methylcobalamin)

  • Biotin (as D-biotin)

  • Pantothenic Acid (Vitamin B5, as calcium pantothenate)

  • Choline (as choline bitartrate) 

  • Calcium (as calcium citrate)

  • Iron 

  • Phosphorus

  • Magnesium (as dimagnesium malate, magnesium glycinate) 

  • Zinc (as zinc citrate) 

  • Selenium (as selenized yeast) 

  • Copper (as copper gluconate)

  • Manganese (as amino acid chelate) 

  • Chromium (as chromium picolinate) 

  • Molybdenum (as molybdenum glycinate) 

  • Sodium

  • Potassium (as dipotassium phosphate) 

  • Vitamin K2 (as menaquinone-7)

  • Benfotiamine

  • Myo-Inositol

  • Boron (as boron glycinate) 

  • Coenzyme Q10 (as ubiquinone) 

  • Alpha-Lipoic Acid (ALA) 


It also contains an active superfood and prebiotic complex, a daily phytonutrient complex, and a dairy-free probiotic blend. 


AG1® claims to be free from dairy, gluten, lactose, egg, peanuts, and animal byproducts. However, it does contain soy. 


Are There Any Side Effects to AG1®? 

Some people experience minor digestive side effects when taking AG1®, like nausea, diarrhea, bloating, or constipation. Additionally, while the ingredients in AG1® are generally considered safe, it’s important to note that some vitamins, minerals, and nutrients may be present at high levels, which can interact with other supplements or pharmaceutical medications. 


Those who are pregnant, breastfeeding, or under the age of 18 are not recommended to take AG1®. 


How Does AG1® Meet Safety Standards?

AG1® claims to meet safety standards by ensuring its ingredients are sourced from high-quality places and partners. Additionally, they claim to have their products third-party tested, that their products are NSF Certified for Sport®, and that they meet the USP standards. NSF Certified for Sport® ensures dietary supplements are free from 280+ substances that are banned by major athletic organizations. 


However, AG1® does not claim that their products are pharmaceutical-grade—something we take seriously at Previnex due to the fact that pharmaceutical-grade products undergo rigorous testing at all stages of production - from raw material testing to production run testing to finished product testing.
