California Proposition 65

Proposition 65 is a California “right to know” law enacted in 1986, formally called the Safe Drinking Water and Toxic Enforcement Act. It requires businesses to inform California consumers when products contain certain naturally-occurring chemicals above California’s threshold levels.

The law covers over 900 chemicals and applies to a wide range of products — from foods (spinach, oysters, roasted nuts and potato chips) and supplements to furniture and electronics. You may see Prop 65 warnings in restaurants, grocery stores, and on many everyday food products throughout California.

Important context: A Prop 65 warning does not mean a product is unsafe or violates any safety standard. It is a disclosure requirement, not a safety violation. California’s threshold for lead (0.5 micrograms per day) is set at 1/1,000th of the level shown to cause harm — an extremely cautious standard that many everyday foods exceed.

Sea moss is a sea vegetable that naturally absorbs minerals and trace elements from ocean water as it grows. This is what makes sea moss so nutrient-rich — it contains over 90 essential minerals directly from the ocean.

However, as sea moss absorbs minerals that are beneficial for human health, it also absorbs trace amounts of naturally-occurring heavy metals like lead that are present in ocean water worldwide. This is not contamination - it is a natural process called bioaccumulation that affects all sea vegetables, seaweed, and marine-based foods.

Because these trace amounts can exceed California’s conservative threshold of 0.5 micrograms per day, we provide the Prop 65 warning to comply with California law and ensure full transparency with our customers.

Lead in everyday foods (for context):

• ½ cup cooked spinach: ~0.9 µg lead per serving
• 1 cup of rice: ~1.5 µg lead per serving
• 1 oz dark chocolate: ~2.0 µg lead per serving
• ½ cup sweet potato: ~1.2 µg lead per serving
• Prop 65 threshold: 0.5 µg/day. FDA interim reference level for adults: 12.5 µg/day.
