If you’re seeking a nutritious health enhancement method, you may wonder: “wheatgrass vs spirulina, what should you use?” These superfoods are packed with vitamins, minerals, and other health-promoting compounds. But, there are some critical differences between them.

Wheatgrass is grass commonly juiced or blended into smoothies. It is a rich source of chlorophyll, thought to detoxify and has alkalizing abilities. Wheatgrass also abounds in vitamins A, C, and E and minerals like iron and calcium.

Spirulina, a blue-green alga, is most popular in powdered and tablet forms. It is an excellent source of protein, vitamins, and minerals, and is also high in antioxidants. Spirulina strengthens immunity and may also help with cholesterol levels.

So, which is the better choice? Dive in for a better analysis.

Spirulina Vs Wheatgrass – Let the Battle Begin!

When it comes to wheatgrass vs. spirulina, both are excellent superfoods. However, nutritional profiles, best health benefits, and side effects vary.

Nutritional Value

Wheatgrass is rich in vitamins A, C, and E, plus minerals like iron. It also has extensive chlorophyll reserves (70%), providing the body with many merits like detox. 

But, does wheatgrass give you energy? Does wheatgrass break a fast? The supplement helps boost energy, providing 25 calories in a teaspoon. If on a ketosis diet, this supply is inadequate to consider it breaking a fast.

  • 25 calories
  • 1g protein
  • 24mg calcium
  • 6g carbs
  • 4g fiber
  • 86mcg vitamin k
  • 1mg iron
  • Zero fat.

One of the biggest worries when dealing with food or supplements is allergic reactions. So, does wheatgrass have caffeine or gluten? Like spirulina, wheatgrass has no gluten or caffeine, making it gentle to many.

Spirulina is an excellent source of protein, vitamins, and minerals, and is also high in antioxidants. One tablespoon (8g) of spirulina powder contains these ingredients:

  • 23.2 calories
  • 2g carbs
  • 4.59g protein
  • 9.6mg calcium
  • 4g fiber
  • 2.23mg iron
  • 108.8mcg vitamin k

Health Benefits

Many superfoods including spirulina boast of improving cardiovascular health. Is wheatgrass in the same category? Does wheatgrass lower blood pressure? Yes, it is rich in chlorophyll, known to help to improve circulation and reduce stress levels.

While cardiovascular health is a big deal, wheatgrass is famous for its anticancer properties. Its chlorophyll protects against cancer by binding to carcinogens and helping the body to eliminate them. Also, its antioxidants help counter cell damage.

Other wheatgrass benefits are:

  • Boosts the immune system
  • Aids in digestion
  • Reduces inflammation
  • Promotes healthy skin, and hair
  • Lowers blood pressure
  • Reduces stress and anxiety.

Although not as excellent as wheatgrass at anticancer properties and other chlorophyll-related strongholds, spirulina has the same merits above. 

Where spirulina shines the most is its huge protein supplies, excellent for body repair and improvements. Before and after a good workout, 70% protein can do wonders to boost your muscle development. Plus, you get it at a lesser heart disease risk than animal protein.

Side Effects

Spirulina is a relatively safe supplement, even in high doses. The most common side effects of spirulina are gut-related issues like upsets and nausea. Other side effects may include headaches and trouble sleeping.

People with autoimmune conditions or allergies should avoid spirulina, as it may trigger an immune response. The supplement isn’t fit for those with PKU and bleeding issues too. Speak to a doctor if considering spirulina while pregnant or lactating to determine its suitability.

Like spirulina, there aren’t significant wheatgrass side effects. It’s okay for most adults with oral usage up to 18 months considered safe. The most common wheatgrass harmful effects include constipation, appetite loss, and nausea.

How To Take

You can take spirulina and wheatgrass in several ways. The most typical way is to mix them with water or add them to a smoothie or juice. You can also take them in tablet or capsule form.

The preferred dose is 1-2 teaspoons of spirulina powder or 1-5 grams of tablets/capsules daily. Higher doses of up to 10 grams per day are popular during uses like detox. For wheatgrass, use similar powder amounts or 1-4g of tablet/capsule daily.

Like wheatgrass, the best time to take spirulina is on an empty stomach in the morning. However, spirulina is more flexible in usage time. You can whip it into a quick smoothie or add it to your favorite meal at lunchtime or before bed.
