Taurine supplements with the fewest additives

Taurine is an amino acid that may benefit exercise performance, liver glycogen storage (for which I think I've seen results), and more. However, many taurine supplements use excipients to make manufacturing easier and less expensive. I try to avoid such excipients when possible. If you want to do the same using brands that provide lab analysis of their purity, my recommendations are:

No-additive taurine gelatin capsule recommendation:

No-additive taurine veggie capsule recommendation:

Positives:
  • silica-free / silicon-dioxide-free
Negatives:
  • contains hypromellose / hydroxypropyl methylcellulose
All ingredients:

Taurine, cellulose (capsule, probably hydroxypropyl methylcellulose).

No-additive taurine powder recommendations:

Powdered taurine is easy to take by mixing it with a drink, or just swishing it around with a sip of liquid. The taste is fairly neutral.

It does tend to clump up easily, so people in humid areas may be better off with capsules. I find it's easiest to sift out the large clumps and pop them in a blender on a low speed to break them up. I imagine a potato masher would work even better because smashing things is fun.
