Prop 65 Lead Warning California Labels

Thank you for writing. I understand your cause for worry regarding the lead and I hope I can ease your concerns!

A little about lead -- Lead is present in small amounts throughout the environment due to its natural occurrence and its release into the environment by human activities. Lead in soil can be deposited on or absorbed by plants, including plants grown for food or used in supplements. Lead that gets in or on the plant cannot always be completely removed by washing or other steps in the processing of the food. So, any product which contain whole foods may have trace amounts of lead in them.

All of the following ingredients in the Tricycline come from plants - berberine sulfate, artemisinin, citrus seed extract (from grapefruit), and black walnut hulls. Berberine is the active constituent of goldenseal. Artemisinin, or qinghaosu, is the active constituent of sweet wormwood (Artemisia annua) - all plants that can potentially contain lead.

Question for you. On the label did it read "Proposition 65" on it? I'm not sure you're aware of Prop 65, but you can learn more about it below.

What is Proposition 65?
In 1986, California voters enacted what is known as the Safe Drinking Water and Toxic Enforcement Act also referred to as Proposition 65 (Prop 65). Prop 65 requires companies to provide warnings to consumers if their products contain a chemical determined by the State of California to cause cancer or reproductive toxicity. It also requires the State of California to publish and maintain a list of these chemicals. The list has continually expanded since the inception of Prop 65 and it currently contains over 800 substances, many of which may be naturally present in the environment.
The law governs extremely low levels of chemicals and is among one of the most stringent reporting laws in the country. The presence of these low levels of chemicals necessitates warnings only. It is important to note that Prop 65 does not ban the sale or use of any product for health or safety reasons.
The most recent list and other Prop 65 information are available on California’s web site:

What kinds of foods and products are impacted by Prop 65?
Almost all foods contain certain levels of one or more of the substances/chemicals (arsenic, cadmium, lead and mercury) recognized by the State of California. In many cases, the exposure levels established by Prop 65 are less than what occurs naturally in fruits, vegetables, grains, and even drinking water.
The limits established by Proposition 65 are as follows:

  • Arsenic: 10 micrograms
  • Cadmium: 4.1 micrograms
  • Lead: 0.5 micrograms

Vitamin/supplement products containing all natural ingredients are naturally going to contain these substances.
