Carlson, nordic and sports research
I take Sports Research and it bumped my vitamin D level up nicely.
You want triglyceride form (rTG), for better absorption not the free fatty acid form (EE) - try Sports Research, Nordic Naturals, Viva Naturals, Carlson.
What are you talking about? Sports Research is IFOS tested.
For example, look up Sports Research, Carlson, or Viva Naturals (all sell IFOS cert oils on Amazon I think) and compare the TOTOX value, it's interesting to see.

AI summary — not a quote
L-Theanine is widely praised on Reddit as a reliable supplement for promoting a state of "calm focus," particularly when used to counteract the jitters associated with caffeine. While many users report significant improvements in anxiety management and sleep quality, a minority of users find it ineffective or experience paradoxical effects like mental alertness when trying to sleep.
Pros
- Effectively reduces jitters and overstimulation from caffeine
- Promotes relaxation and focus without causing heavy sedation
- Helps manage mild anxiety and social anxiety for many users
- Can improve deep sleep quality and duration for some individuals
Cons
- Potential for severe headaches, especially at higher doses (e.g., 400mg)
- Can cause a 'hangover' effect characterized by brain fog and heaviness the next morning
- May be completely ineffective for some users regardless of dosage
- Can interfere with sleep for some by increasing alpha wave activity and keeping the mind active

I accidentally took 400 a few weeks ago and I got a headache so severe that I seriously considered going to the ER.
L-theanine - good for anxiety, brain, longevity
Theanine and taurine are calming. ... Magnesium threonate and theanine are good too but the effects seem more subtle.
My overall oxidative stress with magnesium bisglycinate and L-theanine
L-theanine — subtle, but definitely helps me stay present without feeling wired.
