All-Natural Remineralizing Spirulina Toothpaste

The first time I thought about whipping up my own toothpaste was one afternoon while searching for a healthier and natural alternative. After a frustrating series of searches, running from store to store, and comparing products on Amazon, I was not able to find a brand that didn’t have questionable ingredients. I must not have been alone since one Google search for DIY toothpaste yields an astonishing average of 3,460,000 results. So, why the demand for homemade toothpaste anyway?

Well, I can only speak for myself but in the beginning, my concern were those questionable ingredients. Things like:


• Not only is fluoride a common ingredient in toothpaste, many municipal water supplies are fluoridated. Even though overexposure has extremely toxic effects on the body, fluoride continues to be hard to avoid. Why? Well, the excuse we are sold is that it is good for our teeth…. Hmmm, even though it’s not been proven to prevent harmful oral bacteria. [1] However, its toxic effects cannot be disputed. In fact, the number one reason for poison control calls concerning fluoride is for children who have ingested toothpaste.
• Studies on fluoride show that [2] [3] Long-term ingestion is harmful to the brain, digestive system, heart, bones, and even the tooth enamel it’s supposed to help. [4] [5] [6]
• Skeletal fluorosis is a condition resulting from fluoride consumption because the liver is unable to process fluoride resulting in the toxin being absorbed into the bloodstream where it combines with calcium.
• Fluoride has been shown to cause calcification of cartilage, the essential tissue for joint health.
• Fluoride is toxic to thyroid cells as it inhibits function and causes cell death. [7] Unfortunately, fluoride was used to reduce thyroid function in individuals suffering from an overactive thyroid for decades. [8] Now, the range used in water fluoridation matches the levels that were once used to reduce thyroid function. SCARY. [9]
• Fluoride accumulates and calcifies the pineal gland. The pineal gland plays an integral role in the onset of puberty. Research has shown that girls living in areas with more fluoride exposure experience puberty earlier. [10] And, fluoride has also been linked to damaging defects on sexual function.
• A direct link exists between fertility rates and fluoridated drinking water. Higher levels of fluoride correspond to lower fertility rates. [11]
• Fluoride is toxic to the kidneys and a higher rate of chronic kidney disease has been reported in areas where the water contains high levels of fluoride. [12] [13] Per Chinese researchers, a fluoride level as low as 2 mg/L can cause renal damage in children. [14] While water fluoridation levels may be lower than this, the fluoride accumulates as we are exposed to more from sources such as toothpaste.
• Research suggests that exposure to fluoride causes cardiovascular inflammation and atherosclerosis. [15] [16]
• The Fluoride Action Network reports that, as of May 2013, 43 studies have examined the effect of fluoride on human intelligence. One observation is that fluoride negatively impacts children’s neural development. [17] Another is that children living in highly fluoridated areas have up to five times greater chance of developing a low IQ compared to those who do not. [18]
Need I say more?


Sorbitol, sodium saccharin and other artificial sweeteners are often used in toothpaste to improve taste, regardless that there is no evidence that these sweeteners are safe for use in the mouth.


A sneaky chemical used in antibacterial products. Triclosan was recently found to affect heart function said one study at University of California Davis. The FDA has now banned the use of triclosan.[19]


Another controversial ingredient it is found in many natural toothpastes. Glycerin is a sweet and colorless (typically) plant derived liquid. Some say it can coat teeth and prevent them from benefiting from the minerals naturally found in saliva.


Many toothpastes contain surfactants like sodium lauryl sulfate, which gives toothpaste its foam and lather. Research indicates that SLS cause tissue damage and can contribute to mouth ulcers and canker sores. [20]

Synthetic colors or dyes

Many toothpastes also contain artificial colors and dyes or synthetic flavors. These ingredients are often petroleum based and not something that I want in my mouth.

Want to see my dental routine in action?

While researching natural toothpastes and safe ingredients, I realized I could make a similar goop at home… and I launched a yearlong toothpaste recipe experiment.

Why Spirulina?

All natural spirulina toothpaste diy recipe remineralizing
Spirulina AKA blue-green algae, is a plant that is know to be one of the highest protein and nutrient sources of food available. It’s a superfood that I’m obsessed with.
At 65% complete protein (while beef is a lowly 22%), it contains all the essential amino acids plus some non-essentials as well. It contains a healthy amount of omega-3 as well as some omega-6 and omega-9, it’s high in chlorophyll (a natural blood purifier and immune booster), high in iron (58 time that of raw spinach and 28 times that of beef liver), and it’s full of vitamins and minerals.

If you want a cool way to get more spirulina in your diet, check out my Amazing Green Superfood Popsicle recipe.

This one herb can and should replace all those junkie, wasteful, and overpriced protein powders and fake multivitamins a lot of people are taking, and not absorbing.
In addition to being a nutrient powerhouse, spirulina is also great for tooth remineralization. Even the most mindful of healthy diets are often lacking in vital nutrients and minerals due to our modern depleted soil. Unfortunately, this can lead to vitamin and mineral deficiencies in the body. One of the most obvious symptoms of vitamin and mineral deficiencies in children is tooth decay and cavities. If our body lacks important vitamins such as vitamin A, D and K and minerals like calcium and phosphorous then our bones will suffer. Teeth are bones and they too can become weak. This weakness leads to breakdown, and that leads to cavities. That’s why it is so important to be conscious of what goes into our body by eating a healthy diet, and by being aware of overexposure to toxic ingredients in our environment.

Now that I have worked out the bugs and perfected this recipe I want to share it all with you!

All-Natural Remineralizing Spirulina Toothpaste

A superfood Remineralizing toothpaste recipe that is all natural and low waste.

Total Time 10 minutes


  • 4 tbsp bentonite clay
  • 2 tsp xylitol optional* this sweetener can be controversial, but has been shown to prevent cavities
  • 1/4 tsp spirulina powder
  • 1/8 tsp baking soda
  • 1/8 tsp neem powder
  • 1/8 tsp charcoal powder or 3 activated charcoal capsules
  • 1-2 tbsp coconut oil
  • splash distilled water as needed
  • Pure essential oils for flavor I like peppermint and grapefruit


  1. In a non-metal bowl, mix all dry ingredients well. 

  2. Add in coconut oil a little at a time until you have reached the desired consistency. You may wish to use a splash of water for this step as well. If you like a smooth and whipped texture, you can also use an electric mixer to whip ingredients together. 
  3. Once a paste is formed, add in essential oils for flavor. 
  4. That's all there is to it! I store my toothpaste in a small mason jar. This batch lasts me one month.

Recipe Notes

All ingredients may be omitted, reduced or changed per your preferences. For example, you may wish to add more charcoal powder for a whitening effect. 

For my toddler recipe: I use kaolin clay, baking soda, coconut oil, xylitol, and sweet orange essential oils. I like this one for younger kids since it is white and won't make a huge mess.
