It does not replace blood pressure medicine. Does chia seed lower cholesterol? The meta-analysis found no significant change in cholesterol, triglycerides or blood sugar. Can I eat chia seeds while pregnant? Usual food amounts are widely eaten, but there are no safety data for supplement amounts. Ask your doctor before using larger amounts. ## Sources Source type is not an efficacy rating. A monograph may document traditional use or safety.
