Can I combine several supplements?
Not automatically. First compare the complete ingredients, daily servings and allergens. If you take medicines or have a diagnosed condition, ask a doctor or pharmacist for individual advice.

Seek advice for a sudden or worsening change in memory, confusion, speech difficulty or other neurological symptoms. Also ask for individual advice if you take medicines, are pregnant or breastfeeding, or have a diagnosed condition.
