Spirulina pregnancy

Spirulina pregnancy

Is Spirulina safe during pregnancy? Since Spirulina is packed with proteins, vitamins (Pro-Vitamine A) and minerals like iron which is often deficient during pregnancy, this superfood is usually recommended during pregnancy and breastfeeding. 

A clinical study realized in Chad (Africa) in January 2018 concluded the intake of Spirulina in its traditional form is highly beneficial for increasing β-carotene to achieve an optimal vitamin A status in healthy women and their children. Similar studies have been performed in China and India.



In general, taking the best organic certified Spirulina is deemed safe during pregnancy but since pregnancy is a very important event, it is best to discuss it with your doctor or a health practitioner whom you trust. The same applies to breastfeeding.

Usually cheaper Spirulina doesn’t contain half of the nutrients certified organic Spirulina has anyway and may come from areas heavily polluted with, among others, mercury and arsenic and low standards of production hence the price difference. Even if you are on a budget, it is a lot better to use less quantity and go for quality instead. More does not equal better results anyway!

There is a common concern about Spirulina containing too much Vitamin A, which may cause some problems. However, rather than Vitamin A Spirulina contains pro-Vitamin A, otherwise known as beta-carotene, a gentle and safe ‘pre-cursor’ of Vitamin A easily assimilated by the body.

With Spirulina as with any other natural plant food, the body takes the nutrients it needs and eliminates what it doesn’t need, which doesn’t happen with synthetically derived vitamins & minerals which can contribute to vitamin and mineral imbalances.

The consumption quantities are also important, always start with a small dose at first (5 grams/day) and do not overdo it. Usually, 10 grams per day are safe during pregnancy or whilst breastfeeding.

The antioxidant content of Spirulina has shown to improve ovule & sperm health and prevent preeclampsia (a condition in pregnancy consisting of high blood pressure, swelling of hands and feet and protein in the urine).

A scientific study from Mexico suggests that Spirulina may be helpful in preventing preeclampsia and even curing it because the leading cause of preeclampsia is poor nutrition and oxidative stress.

Numerous studies have shown that preeclampsia is associated with increased oxidative stress in the placenta and vascular system of the mother. Phycocyanobilin (PCB) contained in Spirulina has been shown to inhibit oxidative stress. This may help to protect mother and child from preeclampsia.

Many of the vitamins and minerals in Spirulina are antioxidants, which protect the body from free radical damage. Oxidative damage due to free radicals is one of the contributing causes to fertility issues such as luteal phase defect, poor egg and sperm health, as well as lowered immunity and general poor health.
