All these reactions are allergic rhinitis. Some studies say that Spirulina can improve symptoms of rhinitis. Specifically, it can enhance nasal inflammation and reduce histamine levels in the body. Also, it is useful in case of

Are Spirulina supplements safe?

Doctors or medical health providers take to be safe in regular use, particularly under the light of its long history as a food. But Spirulina can be spoiled or contaminated with toxic or harmful metals, disease-causing bacteria, and microcystins (toxins formed from some algae) if developed in an unsafe environment.

Contaminated Spirulina may lead to liver disturbance, restlessness, vomiting, thirst, weakness, sudden heartbeat, shock, and, ultimately, death. Spoiled Spirulina may be particularly harmful to kids. The NIH suggests studying Spirulina's sources in dietary supplements to make sure they are developed in a safe environment and tested for toxins.

Individuals who are suffering from some autoimmune conditions should not use Spirulina supplements, according to the NIH. As it boosts the immune system, its dietary supplements can worsen symptoms of lupus (systemic lupus erythematosus, SLE), multiple sclerosis (MS), rheumatoid arthritis, and other health problems related to overactive immune systems.

For the same reason, it can also weaken the influence of immunosuppressants that are mainly recommended as a treatment for autoimmune conditions and save your body from rejecting organ transplants.

Spirulina can even interfere with medicines that reduce the speed of blood clotting, involving blood thinners like warfarin and also nonsteroidal anti-inflammatory (NSAIDS) pain medications. Mixing it with pure herbal dietary supplements that minimize the speed of blood clotting can enhance the person's risk of bleeding. Like herbs involve cloves, garlic, danshen, ginger, ginseng, and turmeric, under NIH's claim.

Females who are pregnant or breastfeeding their kids should not use Spirulina as there is a lack of safety research on this group regarding pregnant or breastfeeding women. Individuals who have a genetic health issue, phenylketonuria, must also avoid it. The reason is that Spirulina may worsen their condition, according to the NIH.

As there are not enough scientific shreds of evidence to develop a safe dose range of Spirulina, so, we recommend you speak to a doctor or medical health provider and follow instructions on all supplements to get rid of unsafe doses.

Possible Side Effects of Spirulina

Although specific harmful impacts are linked to Spirulina's usage, taking it may lead to headaches, allergic reactions, muscle severe pain, restlessness, and sleeping disorder in some cases. Individuals having allergies to seaweed, seafood, and other sea vegetables should not use Spirulina.

  • There is not adequate scientific evidence to offer a suggested dose of Spirulina. Different doses of it have been utilized in research.
  • For example, in multiple studies examining Spirulina's advantage for high cholesterol, doses of 2-8 g per day for almost three weeks to 5 months have been utilized.
  • For Learning about its influences on hypertension, one recent research administered a dose of 4 g of Spirulina blue-green algae per day for five weeks.
