Possible Spirulina Side Effects to Watch Out For

You may know by now the many benefits spirulina has for the body, but it is equally important to know whether spirulina side effects should be expected as well. Spirulina are blue algae that grow in alkaline water. Since the 1970's it has been widely used as a dietary supplement in many countries.

Spirulina Benefits and Spirulina Facts

The popularity of spirulina stems from the fact that it contains over 100 kinds of nutrients. It is described to be the most complete food source ever - "The Superfood" as most call it.

Spirulina is a rich source of vegetable protein which is about five times higher than can be found in meat. It is also rich in a wide range of minerals, and vitamins. It is the richest source of beta carotene and vitamin B complex that most people who have vegetarian diets lack.

Spirulina Dosage

Spirulina dosage depends largely on the form being taken. Spirulina products come in the form of spirulina capsules, tablets, powder and flakes. Spirulina extract is also available for those who prefer this type of spirulina diet.

Spirulina Tablet and PowderSpirulina may also be found in combination with other natural products such as chlorella, wheat or barley grams. About ten (to twenty) 500 milligram spirulina tablets a day for adults and five (to ten) for children under 12 are usually recommended. The dose for spirulina capsules and tablets can vary from 250 milligrams to 5 grams a day as well. About a spoonful of spirulina extract or spirulina powder (about 3 to 5 grams) is enough to last a day.

Spirulina Overdose

Spirulina is a completely natural food source. Being natural, it is not expected to give any problems to the body. Theoretically speaking, even if too much is taken, there should be no harm done to the body. However, doing so will only be a waste of time, effort and money.

Adverse Effects of Spirulina

Some people have reported to experience some minor symptoms after taking spirulina. These spirulina side effects include:

  • Slight fever. This can be normal since the body needs to burn extra protein found in spirulina.
  • Slight dizziness and nausea.
  • Thirst and constipation. When taking spirulina, you should increase your water intake. At least half a liter should be taken for the body to absorb the spirulina herb well.
  • Stomach ache and other gastrointestinal symptoms
  • Slight body risk or skin itching

Danger of Spirulina

Spirulina poses no dangers when taken in the recommended dosage. Taking less than 50 grams per day should be relatively safe with no notable side effects. However, as in most dietary supplements, taking exceedingly large doses can cause unwanted spirulina side effects. Because of the high nucleic acid content of spirulina, it can give you increased levels of uric acid, which can consequently cause kidney problems. Due to the high content of vitamins and minerals, impaired liver function might also occur.
