Understanding California Proposition 65

Seeing a warning that mentions cancer or reproductive harm can be unsettling. It deserves a clear explanation.

Proposition 65 is a California law that requires warnings about exposure to certain chemicals. A warning does not, by itself, mean a product violates safety standards or establishes that using it as directed will cause harm. It does provide information you should consider when choosing a product.

Here is what the law means, why it can apply to foods and supplements, and how it fits alongside other standards around the world.

What is Proposition 65?

Proposition 65, officially called the Safe Drinking Water and Toxic Enforcement Act of 1986, requires businesses to warn people in California about certain exposures to chemicals the state lists as may cause cancer, birth defects or other reproductive harm.

The law applies to a broad range of products and settings, including foods, dietary supplements, and everyday consumer goods. It applies to all businesses selling their products in California.

Why might these substances be in a food or supplement?

Some listed substances, including lead, cadmium and arsenic and mercury can be present in soil and water through natural processes, agricultural practices, pollution, or can enter ingredients used in foods and supplements.

For example, plants absorb elements from the soil in which they grow so they may contain small amounts of those elements.

The presence of any listed substance does not necessarily mean they were intentionally added. However, being naturally occurring does not automatically make a substance harmless. The substance, amount and pattern of exposure matter—which is why quality controls and exposure assessments are important.

The law applies to a broad range of products and settings, including foods, dietary supplements, and everyday consumer goods. It applies to all businesses selling their products in California.

Does a warning mean the product is unsafe?

A Proposition 65 warning is an exposure notice. It is not, on its own, a determination that a product is unsafe.

California’s warning requirements operate separately from other regulations and industry standards so a product can meet applicable standards and still carry a Proposition 65 warning.

Why is a warning required at such a low exposure?

California establishes exposure levels for many listed chemicals below which a Proposition 65 warning is not required. These are called “safe harbor” levels.

The methods include substantial protective assumptions. For reproductive toxicants, the warning threshold is generally set at one thousandth of the level shown to have no observable reproductive effect. For carcinogens, the threshold is based on an exposure calculated to cause no more than one additional cancer case in 100,000 people exposed over a 70-year lifetime.

These thresholds help determine when a warning is needed. They are not a point at which harm suddenly begins.

How does California’s Proposition 65 levels compare with standards around the world?

Different authorities use different approaches to managing contaminants in foods and supplements. Some set daily exposure limits, others set maximum concentrations in a product, and Proposition 65 focuses on when an exposure warning is required.

FAQs

Frequently asked questions about pre-workout.

What are pre-workout supplements and what do they do?

A pre-workout supplement is a type of nutritional, ergogenic aid that is meant to be ingested shortly before a workout. These are designed to improve exercise performance and physiological adaptations such as reducing fatigue and making one feel focused and energized.

How do pre-workout supplements enhance workout performance?

Pre-workout supplements increase mental focus and provide a subjective feeling of energy to pump you up for a workout while also improving blood flow for better pumps while training. By increasing energy, pre-workouts can help when training so you can accrue lean muscle mass, and benefit overall fitness. One well-studied ingredient is creatine. It is useful in moves that involve fast, explosive power such as sprinting. Creatine is a substance naturally found in muscles. It is a part of the phosphagen system which helps replenish ATP (the universal energy currency of the cell), in muscles when oxygen levels are low (anaerobic).

Are pre-workout supplements safe to use?

Yes, the pre-workout supplements by MuscleTech are safe to use by healthy individuals. Always consult your physician prior to taking a supplement.
