Is Aluminum Secure to Use? Wellness Mama

Desk of Contents[Hide][Show]

Of all of the poisonous components in private care merchandise, aluminum is a misunderstood and controversial substance. Some declare it’s protected, whereas different sources report that baking powder will be dangerous, even in tiny quantities. So what’s the actual story?

Notice: This can be a lengthy and really science-heavy put up. Aluminum is a controversial substance, and the science is inconclusive, so I are inclined to keep away from it each time attainable. If you happen to’re not within the scientific research surrounding it, skip to the underside to study some sensible tips about how one can keep away from it.

What Is Aluminum?

Aluminum is a metallic we’re all accustomed to and a standard substance in our every day lives (aluminum foil is without doubt one of the most used kitchen gadgets). We discover it in home items, vaccines, medicines, colour pigments, paints, explosives, propellants, and gasoline components. Family supplies and merchandise like ceramics, paper, gentle bulbs, glass, and heat-resistant fibers use oxides.

In meals, anti-caking brokers, coloring brokers, emulsifiers, baking powder (however NOT baking soda), and generally soy-based toddler components use its compounds.

It is very important observe that whereas it’s naturally occurring, the physique has no want for it (in contrast to nutritional vitamins, minerals, and hint minerals). On the flip aspect, it might have some destructive unintended effects. Let’s dig deeper.

Within the Setting

Aluminum contains 8% of the Earth’s crust, making it probably the most plentiful metallic discovered on the Earth’s floor.

As a result of it’s a very reactive aspect, you received’t discover it as a free metallic in nature. As an alternative, it’s at all times sure to different parts corresponding to fluorine, silicon, and oxygen. For instance, soils, rocks, clays, and minerals like sapphires, rubies, and turquoise bind aluminum with different parts. It may possibly additionally bind to particles within the air, dissolve in freshwater, and a few vegetation can take it up by way of the soil.

Human exercise will increase the focus of aluminum in the environment. Acid rain can mobilize it from the soil into water, and numerous industries launch its compounds into our air. Close by mines or industries which course of and produce aluminum metallic, alloys, and compounds may cause excessive environmental concentrations of aluminum. Coal energy vegetation and incinerates can even launch small quantities of aluminum into the setting.

Typical Publicity

The typical grownup within the US ingests about 7-9 mg per day by way of their meals. Entire meals like meat, greens, and fruits might naturally comprise small quantities of this metallic since it’s a naturally occurring aspect within the soil. Processed meals might add different aluminum compounds in baking powder, anti-caking brokers, and coloring brokers.

Common inhalation and dermal absorption expose people. Nonetheless, solely very small quantities of what we ingest, inhale, or take up by way of the pores and skin will enter the bloodstream.

Research estimate that the physique absorbs (bioavailable) 0.1% to 0.3% of aluminum from the weight loss program and 0.3% by way of water. Bioavailability will increase when ingested with one thing acidic (like tomato merchandise cooked in an aluminum pan). If not eradicated by way of the kidneys, it can retailer within the bones, lungs, muscle, liver, and mind.

Poisonous Publicity

That is the place aluminum will get controversial. Whereas consultants acknowledge the toxicity of it, they debate about what ranges are thought-about protected. Most frequently, publicity from one’s occupational or dwelling setting results in acute toxicity. Moreover, others present process sure medical remedies are in danger.

After contaminated workplaces, dwelling environments, and medical remedies, the following most typical supply of over-exposure is from continual use of aluminum-containing antacids, buffered aspirin, contaminated meals, and consuming water. Many well being consultants counter that the true risks accumulate over a extra prolonged time and that many research don’t comply with up lengthy sufficient to disclose long-term results.

Life-style Components Which Can Result in Aluminum Overexposure

  • Working in an setting with aluminum mud
  • Residing in excessive aluminum areas (corresponding to close to aluminum mines and processing vegetation, hazardous waste websites, or the place it’s naturally excessive within the soil)
  • Consuming or ingesting substances that comprise it (i.e., continual antacid use)

Well being Circumstances Which Can Improve Toxicity

Some well being situations make sure people extra inclined to aluminum toxicity. Lengthy-term dialysis exposes these with decreased kidney perform to the metallic by way of the dialysate fluid or different medical sources.

Nonetheless, the incidence of this has declined lately with the usage of uncontaminated fluid. Even with out the contamination from dialysis, since greater than 95% of aluminum is eradicated by the kidney, folks with poor kidney perform usually tend to retailer it of their our bodies.

Signs of Toxicity

Acute publicity may end up in signs like:

  • confusion
  • muscle weak point
  • bone ache, bone deformities, and fractures
  • seizures
  • speech issues
  • gradual development in kids

Ailments of Toxicity

Although drugs usually downplays the hazard of low-dose aluminum publicity, there may be proof in regards to the risks of long-term publicity. Identified long-term results of constant publicity embrace:

1. Bone Ailments

A 2007 research discovered that “sustained publicity to excessive ranges of aluminum may cause bone abnormalities.” The physique deposits the metallic at websites of recent bone development.

If the physique doesn’t correctly eradicate aluminum by the kidneys or bile, the physique shops 60% of it in bone tissue. Animals uncovered to aluminum have elevated bone weak point and brittleness. Deficiencies in calcium or magnesium can exacerbate these results.

Toxicity additionally results in the suppression of parathyroid hormone, which regulates calcium homeostasis. In dialysis sufferers, excessive ranges of serum aluminum (higher than 30 mg/L) have been related to osteomalacia, softening of the bones, and different associated issues.

2. Nervous System Issues

These issues manifest as problem finishing up voluntary and involuntary actions and considerably correlate to occupational publicity. So-called “neuropsychiatric signs” embrace lack of coordination, reminiscence loss, and issues with steadiness.

3. Mind Ailments and Issues

Analysis completed on animals, and dialysis sufferers, make it clear that prime ranges of aluminum within the Central Nervous System (CNS) can result in neurotoxicity. In dialysis sufferers, concentrations higher than 80 mg/L plasma aluminum have been related to encephalopathy (any mind illness that alters mind perform or construction). Even with this information, it has been difficult to evaluate what focus of serum aluminum correlates with mind harm.

4. Respiratory Issues

Individuals who breathe in massive quantities of aluminum mud might develop respiratory issues, corresponding to coughing or irregular chest x-rays. Most individuals who develop respiratory diseases from aluminum accomplish that as a result of their workplaces have excessive quantities of this mud.

In aluminum business staff, probably the most well-researched respiratory impact is named Potroom Bronchial asthma. The frequent signs of this dysfunction are wheezing, dyspnea (labored respiration), and impaired lung perform.

Different adjustments after occupational publicity are: “alveolar proteinosis and wall thickening, diffuse pulmonary fibrosis, and interstitial emphysema,” together with some nodule formation. Publicity may contribute to Shaver’s illness, a pulmonary fibrosis seen in staff uncovered to advantageous aluminum powders.

5. Impaired Iron Absorption

Aluminum might negatively have an effect on hematopoiesis, the physique’s course of of making new purple blood cells, particularly in individuals with an underlying iron deficiency. Aluminum additionally interferes with the metabolism of different metals, particularly an elevated excretion of phosphorus.

Different Potential Well being Results

These are the areas the place aluminum publicity will get controversial, and there may be fairly a little bit of proof supporting its attainable hyperlink to those situations, although extra analysis is required.

Alzheimer’s Illness

You might have heard that you must keep away from aluminum as a result of it might probably trigger Alzheimer’s Illness. Nonetheless, the analysis has come to combined conclusions.

Earlier than I get into the analysis outcomes, it’s essential to know how this illness impacts the mind.

Alzheimer’s illness, or AD, disrupts essential metabolic processes to maintain wholesome neurons (mind cells). These disruptions trigger neurons within the mind to cease working correctly, lose connections with different cells, after which die.

The loss of life of mind cells is what causes the hallmark signs of this horrible illness: reminiscence loss, character adjustments, and the shortcoming to hold out every day duties. Whereas there may be nonetheless loads to be understood about Alzheimer’s Illness, a 2017 evaluate of analysis identifies two irregular constructions within the brains of these with AD: amyloid plaques and neurofibrillary tangles.

Amyloid plaques, first described by Dr. Alois Alzheimer in 1906, consist primarily of insoluble deposits of a poisonous protein-peptide referred to as beta-amyloid within the synapses, or areas between neurons. There’s nonetheless loads to be discovered about these plaques. It’s nonetheless unknown whether or not they instantly trigger the illness or are a symptom of its course of.

Neurofibrillary tangles are collections of abnormally twisted protein strands discovered inside nerve cells. The tangles harm the power of the neurons to speak with each other. The subsequent main function of AD is the lack of connections between neurons. The inhibition of intercellular communication can harm the mind cells and trigger them to die off.

As neurons die, the affected areas start to atrophy, and the mind begins to shrink, ultimately leading to loss of life.

Aluminum’s Function in Alzheimer’s

Some research present that publicity to excessive ranges of the metallic correlates with elevated charges of Alzheimer’s illness, whereas others present no correlation. The identical 2007 research above factors out that a number of research have investigated publicity from consuming water. But, the information is tough to interpret due to the number of research designs and their vary of high quality.

Nonetheless, nearly all of epidemiological research have reported a optimistic affiliation between aluminum ranges in consuming water and the danger of AD. Which means when concentrations rose, so did the variety of circumstances of Alzheimer’s.

Analysis carried out on mind samples experiences that the aluminum focus was increased within the general mind samples, neurofibrillary tangles, and plaques from topics with Alzheimer’s illness than the controls.

Then again, aluminum might have merely an oblique function in inflicting AD. It could amplify situations and promote mechanisms that negatively have an effect on “synergistically” worsening cognitive talents in Alzheimer’s sufferers.

Direct injection of aluminum will increase markers of oxidative stress in animal research. In animal research, it appears that evidently it might have an effect on levels of cholesterol, which can function a possible modulator of Alzheimer-type amyloid formation.

It might improve the aggregation of molecules recognized to type lesions within the brains of Alzheimer’s sufferers. A 2002 research famous that mice fed diets excessive in aluminum confirmed elevated ranges of amyloid. There’s additionally proof that it promotes the aggregation of B amyloid peptide in mice.

A 1991 research established that publicity to the metallic causes the formation of filamentous constructions containing cytoplasmic neurofilament protein, selling the formation of neurofilibary tangles. Nonetheless, in a number of research rats and mice uncovered to very excessive ranges of aluminum didn’t present “profound” cognitive impairment.

Briefly, that is one space that actually wants extra analysis. Because the physique doesn’t have a physiological want for this metallic and there could also be a hyperlink to some well being situations, it might be price avoiding till science learns extra.

Right here is extra information on find out how to detox heavy metals from the physique.

Human Copy

The proof is unclear in regards to the impact of aluminum on copy, although some animal research have pointed to an impact on offspring.

When administered orally, it didn’t appear to have an effect on reproductive capability in both males or females. Publicity throughout gestation didn’t have an effect on maternal well being or the event of the fetuses and neonates.

Nonetheless, massive quantities delay unborn and growing animals’ skeletal and neurological growth. The identical research above carried out in mice confirmed neurobehavioral abnormalities in offspring whose moms got aluminum throughout gestation and lactation.

The CDC’s Company for Poisonous Substances and Illness Registry, Division of Toxicology and Environmental Drugs’s Public Assertion on Aluminum factors out that it’s in breast milk. They declare solely a small quantity will enter the toddler’s physique by way of breastfeeding—typical concentrations in human breast milk vary from 0.0092 to 0.049 mg/L. It’s additionally in soy-based toddler components (0.46–0.93 mg/L) and milk-based toddler components (0.058–0.15 mg/L).

Most cancers

That is one other controversial subject relating to aluminum publicity.

The Division of Well being and Human Companies (DHHS) and the Environmental Safety Company (EPA) haven’t evaluated the carcinogenic potential in people. Whereas it has not conclusively triggered most cancers in animal research, some human research have advised a attainable hyperlink between aluminum and breast most cancers.

In 1984, the Worldwide Company for Analysis on Most cancers (IARC) categorised aluminum as carcinogenic.

A 2012 research means that aluminum-based antiperspirants might improve breast most cancers threat. As a result of most breast cancers develop the place we apply deodorant—within the higher outer a part of the breast, they hypothesize that chemical substances in antiperspirants, like aluminum, take up by way of the pores and skin, particularly when shaving nicks the pores and skin. These chemical substances might then work together with DNA, result in cancerous adjustments in cells, or intervene with the motion of the feminine hormone estrogen, which we all know influences the expansion of breast most cancers cells.

Nonetheless, we don’t totally perceive the direct motion of aluminum and its function in breast most cancers. A 2009 research noticed that aluminum and different endocrine disruptors that hold the physique from perspiring might need different destructive well being penalties as a result of sweating is a pure means of elimination for the physique.

Oxidative Injury

In 2012, this research demonstrated that aluminum creates oxidative stress within the physique, which can additionally improve charges of cancers, and one other 2012 research confirmed it particularly in human mammary cells. A 2001 research demonstrated the identical destructive oxidative impact in pores and skin cells. These research don’t show that it’s a reason for most cancers however actually counsel that it’s problematic sufficient to warrant additional analysis and concern.

I really like utilizing my NanoVi to assist fight oxidative stress. Pay attention right here to my interview on it. 

Aluminum can even bio-accumulate, particularly within the mind. An extra 2012 research reveals that it might probably substitute for minerals like calcium, magnesium, and iron, resulting in deficiencies of those minerals.

Gadgets to Keep away from

Once more, aluminum is a controversial substance. I want we might know its results for positive on long-term human toxicity. Nonetheless, we do know that it isn’t mandatory for the physique, and avoiding it received’t trigger any hurt. So it’s a substance that I personally keep away from as a lot as attainable.

If you’re involved and wish to keep away from aluminum publicity, be careful for these shopper merchandise:


Antacids comprise 300-600 mg aluminum hydroxide, translating to 104-208 mg of aluminum per pill, capsule, or 5mL liquid dose. Whereas the digestive tracts might solely take up just a little of it, it might be a priority for these already experiencing excessive exposures to the metallic or these wishing to keep away from it altogether.

If an individual should take antacids, it’s useful to attend earlier than consuming something bitter or acidic, corresponding to citrus and tomatoes. Acids make it simpler to soak up the aluminum present in antacids. Those that take antacids every day could also be experiencing low abdomen acid as a substitute of excessive abdomen acid.

Buffered Aspirin

One pill of buffered aspirin might comprise 10-20 mg of aluminum.

Meals Components

The Environmental Working Group (EWG) warns that baking powders usually make the most of sodium aluminum phosphate or sodium aluminum phosphate as a leavening agent.

To keep away from this, you may make your individual utilizing baking soda, arrowroot, and cream of tartar.

It is usually vital to notice that baking soda does NOT comprise aluminum, although there may be confusion about this on the web. “Aluminum Free” is a advertising and marketing time period on baking soda packaging. Nonetheless, producers acknowledge that baking soda doesn’t comprise this metallic and is only a advertising and marketing ploy.


Aluminum powder is used as a colorant in lots of cosmetics however primarily in nail polish, eye shadow, eyeliner, and lip gloss. The EWG notes that aluminum goes beneath the names listed within the components as aluminum, aluminum flake, LB Pigment 5, Pigment Metallic 1, A 00, A 95, A 995, A 999, AA 1099, or AA 1199.


Antiperspirants use aluminum zirconium tetrachlorohydrex glycine. The EWG warns that Canada restricts its use. As a easy pure different, make do-it-yourself deodorant with this recipe. (Notice: Even “pure” deodorants like crystal deodorants can comprise aluminum, however you’ll be able to fight this with an armpit detox.)


Many sunscreens and make-up foundations with sunscreen use aluminum hydroxide as an opacifying agent, pores and skin protectant, and beauty colorant. Whereas the EWG provides this chemical its lowest hazard rating, Canada classifies it as “anticipated to be poisonous or dangerous.” If you happen to’re involved, see my beneficial sunscreen listing or use bodily measures like hats and shirts to keep away from burning.


Many varieties of kitchen merchandise and cookware use aluminum, particularly antiques. I make sure that to make use of protected cookware that doesn’t comprise Teflon or aluminum. This put up lists my favourite cookware, however you must know I like to recommend Xtrema ceramic cookware probably the most.

Kitchen Merchandise

Aluminum can also be current in lots of different kitchen merchandise like foil, canned items, water bottles, drink pouches, and tin storage dishes. Analysis reveals that it transfers into meals, particularly when meals are heated in foil or containers or come into contact with it whereas sizzling. Some sources declare that foil is protected for storing chilly meals, however I nonetheless desire to keep away from it.

Fortunately there are straightforward substitutes:

Testing and Regulation

One of the simplest ways to foretell the “aluminum physique burden” is to check bone tissue. Nonetheless, since that’s invasive, a blood take a look at can even decide long-term publicity. A urine take a look at assesses solely latest publicity. One other approach to take a look at is to research a hair pattern, however its worth in general toxicity wants future research.

Authorities Rules

Aluminum is at present regulated in meals, water, and shopper merchandise, although not as tightly within the US as many different international locations.

Consuming Water

The Environmental Safety Company recommends a “Secondary Most Contaminant Degree” or SMCL of 0.05-0.2 mg/L for aluminum in consuming water. Nonetheless, this focus relies on style, odor, and colour, not on if the extent will have an effect on the well being of people or animals.

Client Merchandise

The FDA has decided that the aluminum in meals components and medicinals (aspirin and antacids) are “typically protected.” It has, nevertheless, set a restrict for bottled water of 0.2mg/L.

Office Air

OSHA has set a authorized restrict for aluminum in mud (averaged over an 8-hour workday) for 15 mg/m3 (milligram per cubic meter) of whole mud.

If you happen to reside close to any excessive aluminum areas, I’d suggest getting an AirDoctor Air Filter that may assist clear your air. (Use this hyperlink to get 50% off for a restricted time!)

So, Is Aluminum Secure?

Primarily based on this analysis, I contemplate aluminum to be sufficient of a priority to keep away from when attainable. It’s one more reason why I’m glad I eat unprocessed complete meals and persist with all-natural magnificence merchandise. Some sources argue it’s advantageous, however there may be additionally a physique of proof suggesting it might not be.

This text was medically reviewed by Dr. Jennifer Pfleghaar, D.O., FACEP, ABOIM. Dr. Jennifer is a double board-certified doctor and is now working in Emergency Drugs and has an workplace in Ohio practising Integrative Drugs. As at all times, this isn’t private medical recommendation and we suggest that you just speak along with your physician.

Since we nonetheless want extra analysis to find out how aluminum impacts mind well being, I desire to keep away from it. What do you assume?
