Overview

Overview Information

When you hear “chia,” you may think of “Chia Pets.” These are clay figures sold in the US that support the growth of chia sprouts. But chia has a much longer history as a medicinal herb. It originated in Mexico and was cultivated by the Aztecs. Today, chia is grown commercially in Central America and South America. It is grown mainly for its seed, which is a rich source of omega-3 fatty acids.

People use chia seed for diabetes, high blood pressure, and for generally reducing the risk of heart disease and stroke (cardiovascular disease).

How does it work?

Chia seeds contain a large amount of healthy omega-3 fatty acids and dietary fiber. Researchers think omega-3 fatty acids and fiber help reduce risk factors for heart disease.

Uses

Uses & Effectiveness?

Possibly Ineffective for

  • Obesity. Consuming chia seeds mixed with water twice daily before meals for 12 weeks does not seem to reduce body weight or blood pressure in people who are overweight or obese. Also, eating milled or whole chia seeds daily for 10 weeks does appear not improve body weight or blood pressure in overweight women.

Insufficient Evidence for

  • Athletic performance. Early research suggests that trained athletes who drink a beverage containing 50% of calories from chia seeds (Green Plus Omega 3 Chia seeds) and 50% from Gatorade for 2 days before completing an endurance exercise perform similarly to athletes who drink just Gatorade alone.
  • Diabetes. People who have diabetes are more likely than other people to develop heart disease and stroke. Some early research shows that people with diabetes can lose weight and improve some "markers" of heart disease and stroke risk by eating a type of chia called Salba (Salba Smart Natural Products). However, eating Salba does not affect all heart disease and stroke risk factors and does not seem to reduce body fat or blood sugar levels in people with diabetes.
  • High blood pressure. Early research suggests that taking 35 grams per day of chia flour for 12 weeks reduces blood pressure in people with high blood pressure. It seems to work best in people already taking medicine to lower their blood pressure.
  • Itching. Early research shows that applying lotion containing chia seed oil to the skin for 8 weeks reduces itching.
  • A grouping of symptoms that increase the risk of diabetes, heart disease, and stroke (metabolic syndrome).
  • Other conditions.
More evidence is needed to rate the effectiveness of chia for these uses.

Side Effects

Side Effects & Safety

Chia is POSSIBLY SAFE Early research shows that applying lotion containing chia seed oil to the skin for 8 weeks reduces itching.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Not enough is known about the use of chia during pregnancy and breast-feeding. Stay on the safe side and avoid use.

High blood fats called triglycerides: Blood contains several types of fat, including cholesterol and triglycerides. Triglyceride levels are too high in some people. Eating some types of chia can make them even higher. If you have high triglycerides, stick with using a specific variety of chia called Salba. Salba does not significantly increase triglyceride levels.

Prostate cancer: Chia contains a lot of alpha-linolenic acid. Some research suggests that large amounts of alpha-linolenic acid in the diet might increase the chance of getting prostate cancer. If you have prostate cancer or have a high risk of getting it, avoid eating large amounts of chia.

Dosing

Dosing

The appropriate dose of chia depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for chia. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
