Review on Sundown Naturals L-Arginine 500mg Dietary Supplement, 90 Capsules by Bethany Green

Revainrating 5 out of 5

Goes well with caffeine!

I tried it myself but found no real effect. I then tried my usual caffeine intake and WOW, it kicked my caffeine into overdrive. I definitely had to adjust the amount of coffee/caffeine pills I was taking with the recommended 3 pills 3 times a day L-arginine. This is good as I was consuming up to 1200mg of caffeine per day and had too much tolerance. I've now reduced my caffeine dose to 800mg per day and only take one dose of L-arginine twice a day.

Pros
  • Amino acids
Cons
  • Doubtful purchase for the elderly
