Recommended Daily Intake of Goji Berries
For most healthy adults, a daily intake of 15 to 30 grams (approximately 1 to 2 tablespoons) of dried goji berries is considered a safe and beneficial amount. This dosage is sufficient to provide the body with a potent dose of antioxidants, vitamins, and minerals without overdoing it. For fresh goji berries, the recommended amount is higher, around 150 grams per day.
It is worth noting that these recommendations are for general health and wellness. In traditional herbal formulas, goji berries might be used in slightly different dosages. For instance, a 15-gram serving is often cited as enough to supply sufficient zeaxanthin, an important antioxidant for eye health. Ultimately, starting with a smaller amount and gradually increasing intake is a prudent approach to gauge your body's response.
Factors Influencing Your Goji Berry Intake
Individual needs and circumstances can affect the optimal amount of goji berries for each person. These factors include:
- Body weight and metabolism: Larger individuals may tolerate slightly higher doses, while smaller individuals might benefit from less.
- Health goals: Someone seeking a high concentration of antioxidants for specific concerns might aim for the higher end of the recommended range, while someone simply adding a nutrient boost might stick to the lower end.
- Form of consumption: Dried, fresh, juice, and supplement forms have different potencies and recommended servings. For example, 120 ml of goji berry juice is a common daily dose, whereas a supplement capsule may contain a more concentrated extract.
- Medication use: This is a crucial factor, as goji berries can interact with certain prescription drugs. Always consult a healthcare provider if you are on medication before adding goji berries to your diet.
Potential Side Effects and Precautions
While goji berries are safe for most people in moderation, overconsumption can lead to a few adverse effects, primarily due to their high fiber content and potent properties.
Common Side Effects from Overconsumption
- Digestive Issues: Eating a large quantity of goji berries in one sitting can cause bloating, gas, and diarrhea, especially for individuals not accustomed to a high-fiber diet.
- Insomnia: Some individuals have reported difficulty sleeping after consuming an excessive amount of goji berries.
Significant Precautions
- Medication Interactions: Goji berries can interact with several types of medication. The most well-documented interaction is with blood thinners like warfarin (Coumadin), which can increase the risk of bleeding. They can also lower blood sugar and blood pressure, posing a risk for those on diabetes or high blood pressure medication.
- Pregnancy and Breastfeeding: Due to the presence of betaine, which may cause uterine contractions, goji berries are not recommended for pregnant women. There is also insufficient data on their safety during breastfeeding.
- Allergies: People with allergies to other nightshade plants, such as tomatoes, peaches, and tobacco, may be more prone to an allergic reaction to goji berries.
