Spinach – A Nutrition Packed Powerhouse

Spinach was made famous by the classic Popeye cartoon and its health benefits match the hype.

Spinach provides essential nutrients that benefit almost every aspect of health. Keep reading to find out how this humble vegetable can strengthen bones, optimize heart health, and even save your eyesight!

Loaded with Nutrients

Spinach is packed with many essential nutrients like vitamin A, vitamin K, vitamin C and folate. It’s also very high in fiber, which keeps you ‘regular’ while maintaining steady blood sugar levels.

Just one cup of raw spinach (1) nutrients include:

  • 0.8 milligram iron
  • 23.7 milligrams magnesium
  • 58.2 micrograms folate
  • 145 micrograms vitamin K
  • 2,813 international units vitamin A

Spinach Can Help Prevent Macular Degeneration

The leading cause of vision loss over age 60 is age-related macular degeneration. A condition that can slowly rob you of the ability to recognize faces or do detailed work by eroding your central vision.

The first signs are blurred vision and needing more light to read comfortably. Eventually straight lines start to look crooked. Finally dim or empty areas will block your central vision.

As the disease advances, delicate blood vessels in the eye can leak blood and fluid builds up in the retina, resulting in more damage.

However, eating spinach, which is rich in lutein and zeaxanthin, can lower the risk of developing macular degeneration.

Research in Biomed Research International found that a diet higher in lutein and zeaxanthin caused significant improvements in patients with macular degeneration (2).

High in Magnesium Spinach Supports Heart Health

As the fourth most common mineral in the body, magnesium is a critical component in over 600 health-maintaining chemical reactions. Magnesium benefits our health in many ways, including:

  • Relaxing blood vessels to keep blood pressure in a healthy range
  • Playing a role in regulating blood sugar and insulin levels to prevent type 2 diabetes
  • It’s critical for healthy nerve and muscle function
  • Magnesium is a buffer between the brain’s synapses maintaining healthy cognition

Magnesium is so essential for the healthy function of most cells in our bodies that a magnesium deficiency can lead to serious health problems.

A 2016 study published in The Journal of the American Heart Association, finds low magnesium levels are associated with death from heart disease and heart failure (3).

One researcher many reviewed previous studies to conclude that magnesium levels could be the greatest predictor of heart disease — not cholesterol or saturated fat intake (4).

Spinach Boosts Testosterone, Muscle Mass and Strength

Spinach has several properties that can aid your body in increasing testosterone production including:

Spinach also has a special and powerful phytonutrient called “phytoecdysteroids” which has been shown in human case studies to increase muscle mass and strength (5, 6, 7).

Phytoecdysteroids have also been shown to help decrease stress which is a huge testosterone killer. (8)

I need to point out the study on stress was performed on rats and has not yet been verified on humans (due to the complicated nature of testing) so we cannot yet say for certain it will have the same effect on us.

However, more research is being done all the time on and it does make logical sense the benefit would at least in part carry over.

Rich in Chlorophyll

Spinach is rich extremely rich in Chlorophyll which is what gives it that dark green pigment.

Chlorophyll is one of the healthiest phytonutrients on the planet and is believed to help improve health on several levels.

Researchers still need to prove more in human case studies to show conclusive evidence, however, preliminary research is still promising and some of the potential benefits which have been linked to chlorophyll include:

  • Blood Detoxification
  • Faster Wound Healing
  • Gut Health
  • Increased Energy
  • Stronger Immune System
  • Cancer Prevention
  • Diabetes Support
  • Fights Cardiovascular Disease
  • Improved Brain Function

Anti-Cancer Benefits

Including leafy green and cruciferous vegetables like spinach in your diet can help prevent cancer.

Spinach can slow the formation of cancerous cells by defending against DNA damage and reducing free radical damage with the antioxidants neoxanthin and violaxanthin (9).

These powerful substances protect our cells from mutations that could eventually lead to cancerous tumors.

Spinach also contains chloroplast and chlorophyll which act as potent cancer-fighters by removing carcinogenic substances from the body, reducing inflammation, and also slowing free radical damage (10).

Maintains Healthy Blood Sugar Levels

There are protective steroids in spinach known as phytoecdysteroids.

Research has shown that this class of steroid can increase sugar metabolism to maintain stable blood sugar levels (11).

This is especially important to prevent conditions like prediabetes (metabolic syndrome), and type 2 diabetes, because it reduces the amount of insulin your body needs to produce.

The fiber in spinach will also help slow sugar absorption in the gut to keep blood sugar stable (12).

Spinach Supports Bone Health

Vitamin K is critical for healthy bones and spinach is jam-packed with this essential nutrient. The vitamin K in spinach can help prevent osteoporosis and strengthen bones to prevent fractures (13, 14).

Additionally, it plays a powerful role in blood clotting and reducing inflammation in your body (15, 16).

Spinach Boosts Brain Health

Leafy greens like spinach, kale, and broccoli provide high levels pf brain-healthy vitamins like folate, lutein, vitamin K, and beta carotene. These plant-based nutrients may even help slow cognitive decline.

Studies show that spinach can enhance brain health by protecting against age-related disease and could even reverse some brain damage due to stroke (17).

One animal study found that giving rats a supplement of spinach extract reversed age-related cognitive decline and improved their motor performance (18).

Next Level Difference

Our Next Level multivitamin features 400 mg of spinach extract super concentrated at 4:1 which is equivalent to 1,600 mg of spinach extract!
