Vitamatic delivers the same 200 mg L-theanine and 100 mg caffeine as the capsules above for a fraction of the price: 120 tablets for around $10. The panel also declares 75 mg calcium from calcium carbonate, and the other-ingredients line runs to microcrystalline cellulose, calcium carbonate, stearic acid, croscarmellose sodium, silicon dioxide and magnesium stearate. The listing shows a third-party certificate of analysis covering identity, microbiology and heavy metals.
How we built the SAC Product Score™ — 8.2/10
Ratio & Dose vs the Trials30%9/10
200 mg L-theanine to 100 mg caffeine is the trials' 1:2 ratio at double the Owen dose in one tablet.
Ingredient Sourcing & Form20%6.4/10
Generic caffeine and L-theanine pressed with calcium carbonate, stearic acid, croscarmellose sodium, silicon dioxide and magnesium stearate; the longest excipient line here.
Testing & Manufacturing20%7.8/10
A third-party certificate of analysis for identity, microbiology and heavy metals is shown in the listing gallery; no seal is printed on the panel itself.
Dosing Flexibility & Practicality15%8.4/10
A tablet can be halved for a half dose; 120 tablets per bottle.
Value15%9.6/10
About $0.08 per tablet, the cheapest full dose on the list by a wide margin.

Marketing claims vs. reality
False
“Clean formula, nothing extra.”
The panel lists 75 mg calcium carbonate and six other ingredients; it is the longest excipient line on this list.
Verified
“Third-party lab tested.”
The listing shows a certificate of analysis with identity, microbiological and heavy-metal results for the product.
What our test actually found
01The price is real and so is the certificate
A full 100/200 dose for eight cents, with a COA you can actually read, is a genuine budget option that most brands at this price do not offer.
02It is a tablet, and it reads like one
Six binders and a calcium filler are what it takes to press this into a tablet. None are harmful; all are the opposite of the two-ingredient capsules above.
Pros & cons, no sugar-coating
Pros
- About $0.08 per full 1:2 dose
- Certificate of analysis shown in the listing
- Tablet can be split for a 50 mg step
- 120 tablets per bottle
Cons
- Six excipients plus 75 mg calcium carbonate
- Generic caffeine, no source
- Tablet format dissolves more slowly than a capsule
The budget pick, honest about being a tablet
If you want the studied pairing at the lowest price and a certificate to go with it, Vitamatic is the answer. You give up a clean label and natural caffeine. For most people testing whether caffeine plus theanine works for them, that is an acceptable place to start.
