As long as suggested serving sizes are adhered to, this product is considered safe. However, if you are taking any medications that affect the heart or diabetes, a medical professional should be consulted beforehand.

If taking more than the recommended amount, side effects such as vomiting, nausea, headache and gastrointestinal pains may be experienced from use of this supplement. However, these side effects are quite rare. Taking a larger amount of one supplement may cause the absorption of other supplements to be less effective; it is important to supplement other minerals such as copper and zinc to make up for what is being lost.


Do not exceed the recommended dose. Not intended for pregnant or nursing mothers. Not intended for children under 18 years of age. If you are taking any medications, have a known medical condition, or are planning a medical procedure, consult your doctor before use. Discontinue use and consult your doctor if any adverse reactions occur. Please read the Safety Information section for more details.
