Is spirulina good for male fertility? Is spirulina good for female fertility? Let’s find out what scientific research has found so far on the potential benefits of spirulina for fertility.

 

What Is Spirulina?

 

Is spirulina good for fertility?

You may recognize spirulina as a dark green supplement, whether in the form of tablets, capsules, or powder, sold in your favorite health stores. Despite its color, spirulina supplements are made from blue-green algae that naturally grow in freshwater.

Spirulina has been a popular natural supplement because various studies have supported its superfood status. The microalgae is naturally rich in vitamins, minerals, fatty acids, and carotenoids that aren’t typically available in a single food source.

On top of that, spirulina is very high in protein and contains essential amino acids. Its main pigment, phycocyanin, is one of the powerful antioxidants that may protect reproductive organs from free radical damage.

Preclinical studies have revealed that supplementing with spirulina may provide several health benefits, including lowering blood pressure, cholesterol levels, blood sugar, and weight management.

Studies that investigated possible spirulina benefits for fertility are relatively fewer. But they have also provided promising evidence that the blue-green algae may be able to help with male and female fertility.

How can spirulina help in fertility?

Fertility, or reproductive health in general, is complex and can be affected by other health and lifestyle factors. Pre-existing health conditions can also make it tougher to conceive, while, in other cases, age can also be a factor.

In any situation, keeping your nutritional intake is vital. You’ll notice that some of the best supplements for fertility over 40 years or younger promise to provide the nutrients you may lack from your typical diet.

The interest in spirulina’s potential to aid fertility treatments is also widely rooted in the blue-green algae’s rich nutritional profile. Along with a high protein content, spirulina contains nutrients with antioxidant and anti-inflammation properties.

Human studies and clinical trials on how spirulina can help with fertility are still limited.

However, research on spirulina indicates that its vitamins, minerals, amino acids, fatty acids, carotenoids, and pigments may help fight oxidative stress and inflammation.

Some evidence also suggests that spirulina consumption may help manage stress, improve hormonal imbalances, and enhance gut health, which might have positive outcomes for healthy fertility.

 

1. Spirulina for Fertility: A Nutrition Powerhouse

 

Multiple analyses of spirulina species have all confirmed that the blue-green algae can be a very good source of various nutrients. When trying to conceive, anyone planning to take spirulina should also pay particular attention to certain macro and micronutrients indicated in spirulina product labels.

A nonsystematic review summed up the most important nutrient that may play a role in supporting healthy fertility in women. Several of them have also been found to be present in spirulina.

Some of these nutrients are:

 

Can you get these nutrients from taking spirulina for fertility?

 

Values of spirulina nutrients vary in different studies, but overall, there’s evidence that the blue-green algae may contain the vitamins and minerals mentioned above.

Data from the USDA indicates that every 100g of spirulina products may contain:

  • 57.5 mg protein
  • 120 mg calcium
  • 28.5 mg iron
  • 7.2 mcg selenium
  • 195 mg magnesium

In other studies, it’s said that spirulina contains trace values of B vitamins and tremendously higher contents of:

  • Calcium — 180% more than milk
  • Iron — 5,100% more than spinach
  • Protein — 670% more than tofu
  • Beta carotene — 3,100% carrots

While these data support the nutrition powerhouse status of spirulina, the exact amounts of macro and micronutrients in each spirulina product will likely differ. When shopping for spirulina supplements, don’t forget to read the labels.

 

2. Spirulina for Antioxidant Boost 

 

Phytonutrients in spirulina are known for their antioxidant effects, making the blue-green algae a suitable ally in fighting oxidative stress.

Oxidative stress occurs from accumulating unstable molecules called free radicals, including reactive oxygen species.

Cell and DNA damage due to increased oxidative stress and chronic inflammation is linked to various diseases. Research also indicates a link between oxidative stress and female reproduction. Studies have also associated oxidative stress with sperm dysfunctions and male infertility.

So, what can you do to counter oxidative stress? Along with a healthier lifestyle, incorporating antioxidant-rich dietary supplements may help.

Minerals like zinc and selenium and vitamins like vitamin C and E are not the only antioxidant sources in spirulina. The blue-green algae is immensely rich in phycocyanin, demonstrating several mechanisms to fight oxidative stress.

Beta-carotene is also one of the richest carotenoids in spirulina. Experts noted that beta-carotene may aid in cellular growth.

 

Are There Spirulina Benefits for Male Fertility?

 

There are only a few studies conducted with human subjects that have investigated the effects of taking spirulina for male fertility. Most of the research was conducted in vitro or on animal subjects. Nevertheless, the findings are promising.

In a 2018 preclinical study on 40 men with idiopathic infertility, participants consumed 2 g spirulina daily for 12 weeks along with a doctor-recommended fertility regimen. No significant difference in sperm quality was observed between spirulina and control groups. However, researchers recorded a 5% increase in pregnancy rate in the wives of the spirulina-treated participants compared to 0% in the control group.

An animal study also observed improved sperm quality in bovine subjects following consumption of Spirulina maxima extract.

 

What Are the Spirulina Benefits for Female Fertility?

 

The antioxidant activity of spirulina may help protect egg cells from oxidative damage and promote mature egg health.

One study supported this claim, noting that supplementing Chlorella vulgaris and Spirulina platensis extracts reversed the monosodium glutamate-induced reproductive dysfunctions in albino mice.

The same experiment observed an improvement in the quality of oocytes (developing egg cells) following chlorella and spirulina supplementation.

 

Is Spirulina Good for the Uterus?

 

More animal studies also demonstrated the positive effects of spirulina on uterine health.

Spirulina platensis inhibited uterine oxidative damage and muscle reactivity induced by strength training in female Wistar models.

Another study with female Wistar rat subjects revealed that spirulina supplementation via oral route may reverse DNA and tissue damage in the uterus caused by arsenic consumption.

 

3. Spirulina for a Healthier Gut Microbiota

 

There’s emerging evidence linking gut microbiota health with human reproductive functions.

Several studies have suggested that the human microbiome may affect regulating sex hormones and in various stages of female reproduction.

Research in recent years also provided more insights into how the disruption of gut microbiota may be related to endocrine disorders, thus potentially causing reproductive dysfunction.

In multiple studies, spirulina exhibited its ability to support gut health. For instance, daily spirulina supplementation showed positive effects in modulating colonic microbiota in animal subjects.

Another animal study also showed that supplementing with spirulina may reduce intestinal inflammation and address gut microbiota imbalance.

 

Is Spirulina Safe When Trying to Conceive?

Does spirulina help fertility? Does spirulina boost ovulation?

An added benefit of taking spirulina is that the blue-green algae has been categorized as generally safe for human consumption.

With proper guidance from your healthcare provider, regular spirulina supplementation is likely safe when you’re trying to conceive.

Although there’s limited clinical evidence of spirulina’s effect on fertility, it can still be an excellent source of nutrients that are critical for conception.

It is yet to be established if spirulina directly encourages ovulation. However, its protective effects on uterine tissue and its antioxidant properties may offer support in this aspect.

 

What Does Spirulina Do for PCOS?

 

Is spirulina good for the ovary?

Polycystic ovarian syndrome (PCOS) is one of the most widespread hormonal conditions that directly affects female fertility.

However, it is a common misconception that a PCOS diagnosis means a woman can’t get pregnant at all. Decreased fertility is, technically, only a symptom of this condition. That means there are treatment options to manage it.

Diabetes medications like Metformin are one of the common conventional treatments for PCOS. Spirulina was found to be just as effective as Metformin in improving ovarian conditions in rat models with PCOS in a 2022 study.

 

Frequently Asked Questions

 

Does Spirulina Increase Testosterone?

 

A clinical study to confirm spirulina’s effect on testosterone in human males is yet to be established.

However, studies on animal models found that spirulina supplementation led to increased testosterone levels that were negatively affected by physical stress and arsenic-induced testicular damage.

 

Does Spirulina Affect the Menstrual Cycle?

 

We need more evidence to confirm spirulina’s role in regulating the menstrual cycle and relevant hormones. But it’s worth noting that spirulina is a rich source of gamma-linoleic acid (GLA), which may improve premenstrual syndrome.

 

How Much Spirulina Should I Take for Fertility?

 

There’s no scientific consensus yet on the right spirulina dosage for fertility or for any health goals.

Clinical studies that investigated the benefits of spirulina for various health conditions administered daily doses that range from 1 to 10 g. Meanwhile, most spirulina supplement makers recommend 3 to 5 g doses daily.

 

Should You Take Spirulina for Fertility and Reproductive Health?

 

As we look forward to seeing more scientific evidence on how spirulina can support healthy fertility in men and women, we have to appreciate the pieces of preliminary evidence we have now.

Most of them agree that spirulina’s nutritional profile and antioxidant properties may provide potent support for fertility treatments.

In any case, the top advice you may get is to eat healthy foods to get adequate nutrition, which is very important in your fertility and pregnancy journey. For that alone, adding spirulina to your diet is worth considering.

However, keep in mind that spirulina is not currently approved to treat any health condition and as a fertility treatment, so don’t forget to consult your doctor.
