chlorella dangers

Can you imagine that dietary supplements, chlorella included, don’t undergo FDA regulation? That means that there’s no guarantee of their safety or effectiveness. While many consider it often safe, there are potential chlorella dangers and side effects.

For example, chlorella may cause digestive issues. So, you need to know how much to take and in what durations. It may also interact with some medications, including blood thinners. Chlorella may be unfit for users with allergies like iodine.

So, is chlorella right for you? Decide after adequately understanding the possible dangers and side effects of chlorella.

Why Should You Use Chlorella?

Chlorella is a nutrient-rich superfood that can help improve your overall health. Some potential benefits of chlorella include:

Chlorella enhances white blood cell and antibody production to strengthen the immune system. It can help minimize swelling by lowering pro-inflammatory cytokines and boosting anti-inflammatory cytokine levels.

The benefits of chlorella for hair include thickening, lengthening, darkening, and shining. Chlorella can help promote healthy skin by providing essential vitamins and minerals, plus reducing inflammation.

Chlorella can help enhance detoxification by binding to heavy metals and toxins in the body and helping to eliminate them.

Chlorella can help support cardiovascular health by reducing cholesterol levels and blood pressure. This superfood is also excellent due to chlorella fibromyalgia relief. It helps with sleep, pain, anxiety, and more.

Chlorella can help maintain healthy blood sugar levels by stabilizing blood sugar levels and helping to reduce insulin resistance.

Chlorella can support cognitive health by reducing oxidative stress and inflammation while improving blood flow to the brain. Chlorella can help reduce stress levels by reducing the stress hormone cortisol.

How Should You Consume Chlorella?

It is best to stick to the recommended dosage. Chlorella is a concentrated source of nutrients. So, taking too much can cause side effects like nausea or diarrhea. Start with a lower dose and increase gradually as tolerated.

So, how much chlorella per day is enough?

Though no universal chlorella dosages exist, children should take lesser than adults as with other medications. Three-year-olds can start with about 600mg. Users above ten can begin with 3g of chlorella and raise their intake to 10g. 

The supplement’s applications may alter your dosing needs. Some use it for constipation, but does chlorella make you poop? The superfood may improve your bowel movements in higher consumption from 12g.

Side Effects of Excessive Chlorella Consumption

Like most things, consuming too much chlorella can lead to some cons. Its side effects can include digestive issues like:

  • Nausea
  • Upsets
  • Vomiting
  • Green stool
  • Diarrhea
  • Gas

Chlorella can also cause headaches, dizziness, and fatigue. Therefore, consult with a healthcare professional before consuming large chlorella amounts. To be safe, only take it in moderation.

Some people may experience an allergic reaction to chlorella. A reaction can cause breathing difficulties, itchiness, and a swollen face, lips, throat, or tongue.

Drugs That Interact with Chlorella

Chlorella may interact with medications for blood-thinning purposes, such as warfarin. It contains high vitamin K amounts, which can cancel out the workings of these medications. Speak to a healthcare provider before taking chlorella if you are on blood thinners.

Chlorella may also interact with photosensitive medication. These medications may cause increased sun sensitivity. If you are taking photosensitive treatments, use sunscreen or stay in the shade to counter sunburn.

What To Look for in Chlorella Sources

When looking for a chlorella source, it is essential to consider the quality of the product. Chlorella is a type of algae, and like all algae, it can absorb heavy metals and other contaminants from the environment.

Is Taking Chlorella Making You Tired?

Chlorella may boost energy and endurance. These energy-boosting effects may be due to its high concentration of chlorophyll. Chlorophyll increases adenosine triphosphate amounts, which provides cells with energy.

If taking chlorella and you feel tired, you may be sensitive to it. It may also be due to issues unrelated to the superfood, like inadequate sleep or dehydration.

Not many studies cover chlorella impacts on fatigue. If you’re worried about feeling tired, talk to your doctor.

Does Chlorella Aid in Body Alkalinization?

Chlorella may aid in body alkalinization. It is a rich source of chlorophyll, which is an alkalizing agent. Chlorella also contains other alkalizing minerals like calcium, magnesium, and potassium.

Unsuitable groups may also experience chlorella side effects. Examples include:

  • Those under blood-thinning meds
  • Those under medications inducing photosensitivity

Can Chlorella Cause Blood Clots?

Chlorella does not cause blood clots in the healthy. However, for those on thinners, taking chlorella may lower your medicine’s effectiveness. Why? Chlorella contains Vitamin K, an essential nutrient for blood clotting.

Is Chlorella Supplementation Beneficial to the Liver?

The liver filters toxins out of the blood and breaks down fats. When overloaded with toxins, it can get damaged. Liver damage can cause several health problems, including fatty liver disease.

Chlorella helps to remove toxins from the body, reducing the burden of detox duties. Chlorella is also a powerful antioxidant and can help to protect the liver from damage.

Is Chlorella Toxic?

Chlorella is not toxic provided it grows in sterile conditions and is free of contaminants. When consumed in large quantities, it can cause gastrointestinal upset.

When it comes to toxicity, a typical question is: “does chlorella have iodine?” Though there is a low chlorella iodine content, those allergic may encounter issues should they take it. However, the supplement is often safe for most people.

How Long Does It Take For Chlorella To Produce Results?

It is best to give chlorella supplements at least a month to take effect. Some people may start to notice changes within a few weeks. Others may need up to three months to see results.

Chlorella is a slow-acting supplement, so it is crucial to be patient and consistent with its use. Results vary depending on factors like age, health, and diet.
