Aspirin (acetylsalicylic acid) products with the fewest additives

Many aspirin brands contain questionable additives that you might not expect. For example, silica or silicon dioxide are often added to prevent caking, magnesium stearate or stearic acid for easier manufacturing, artificial colors for visual appeal, hypromellose (hydroxypropyl methylcellulose) as an emulsifier or thickener, sodium lauryl/laureth sulfate (SLS/SLES) as an emulsifier, titanium dioxide for whitening, propylene glycol as a preservative, and povidone as a binder.

I try to avoid those additives because they may have questionable health effects. If you want to do the same, I have some recommended brands depending on your needs:

Recommendations for those who don't need an enteric/safety coating

For most people that don't need an enteric coating, the simplest approach is to buy aspirin tablets with the fewest excipients. Fortunately, there are couple brands of aspirin whose only ingredients are aspirin and starch:

I haven't found an online source for this product. It isn't carried on Walmart.com.

Finding locally

You can view the product page on walmart.com to check local store availability, though be warned that it showed as available in my local Walmart without actually being carried.

All ingredients:

Aspirin, starch.

I doubt this brand will be available in many local stores.

All ingredients:

Aspirin, corn starch.

Other local sources

Another alternative is to check discount or dollar stores, who will sometimes carry off-brands that are also just aspirin and starch. Dollar Tree is one example; you can try their store finder to ask if your local store has Assured brand non-enteric aspirin.

Don't bother looking for the uncoated Kroger/King Soopers aspirin I had suggested in the past, it has been discontinued.

Recommendation for those who do need an enteric/safety coating

Unfortunately, the enteric-coated brands I've been able to find still have some undesirable excipients. I think best of the bunch is:

Finding locally

This product should be common in any local store. Don't confuse it with the common Bayer Coated Tablets, which are not truly enteric-coated. The label should explicitly mention "Safey Coated".

All ingredients:

Aspirin, black iron oxide, brown iron oxide, carnauba wax, corn starch, D&C yellow #10 aluminum lake, FD&C yellow #6 aluminum lake, hypromellose, methacrylic acid copolymer type C, polysorbate 80, powdered cellulose, propylene glycol, shellac, sodium lauryl sulfate, triacetin, triethyl citrate.

This is the best enteric coated-product I've been able to find, but it unfortunately contains artificial colors, hypromellose, sodium lauryl sulfate, and propylene glycol.
