⚠️ Warnings & Precautions

Keep away from children.

Warning: If you are pregnant, nursing or taking any medications, consult your doctor before use.

If any adverse reactions occur, immediately stop using this product and consult your doctor. If seal under cap is damaged or missing, do not use.

🧪 Formulation Notes

The CRaNiULS formula is based on the Council for Responsible Nutrition's (CRN) Upper Level of Supplementation (ULS). Rather than use the Food and Drug Administration's Recommended Daily Intake (RDI), CRN examines current scientific research to determine the maximum a human can consume with no adverse effects. Believing that optimal health levels lie closer to the ULS than the RDI, one CRaNiULS capsule contains 50% of the ULS for the nutrients listed.

Due to the size limitations this formula does not contain calcium, iron, vitamin K, magnesium, potassium, phosphorous and copper.
