The depression could be from downregulation of GABA/serotonin/dopamine. Unfortunately (or perhaps fortunately) I only have experience with those two adaptogens, both of them being mushrooms. Maca is next on my list to try, but a word of advice: Get gelatanized (cooked) maca, because the raw root that is most commonly sold contains toxins and has caused several people to experience such abdominal pain that one person passed out for four hours from the pain, and his friend vomited immediately. It could have also been from a tainted batch, but who knows? When I first started researching adaptogens, there was a prerequisite in the definition of "adaptogen" that involved a substance that didn't produce side effects, or if it did, they were minimal. I certainly feel misled, but I have also experienced positive effects from them. But to say they are devoid of any troublesome side effects simply isn't accurate, or I haven't found a true adaptogen yet.
The reason I started cordyceps and reishi was because a coworker emphatically told me about them. They had changed his life, and he consumed a tea of cordyceps every day before switching to reishi. I saw him become increasingly hostile in the workplace, and he eventually hit rock bottom, swearing the stuff off. I continued on with cordyceps, and tried reishi out of curiosity. That's when I started to wonder about the whole "intelligence" thing. How can an herb or mushroom be so in tune with each person's body functions that it helps regulates them to normal levels? This sounds otherworldly to me. There is certainly something strange and mysterious about reishi, but my trust factor just isn't there to try it again anytime soon. And cordyceps had no effect on my mood, except to stabilize it. It rather makes me emotionless, like a machine, though I'm full of energy and focus. Reishi took me more for a ride, pulling up past emotions and memories, and making me think outside the box.
I may give lysine a whirl afterall. And you were right, the renal failure was in a woman who took high doses for five years:
L-Lysine has been reported to cause Fanconi syndrome and tubulointerstitial nephritis. Fanconi syndrome is impairment in renal proximal tubular function and may lead to acidosis, dehydration, and electrolyte imbalances. It is often treated supportively until the underlying cause is addressed. A single case report identified a 44-yr-old woman who developed Fanconi syndrome and tubulointerstitial nephritis after consuming 3000 mg/d L-lysine for 5 yr. Subsequently, the patient progressed to chronic renal failure (33).
Also from the same site regarding confirmed renal failure: Chromium (not fatal), Creatine (fatal due to multisystem organ failure in one case), geranium (probably fatal), Vitamin C (not fatal), cranberry tablets (not fatal), wormwood oil (not fatal), licorice (not fatal), etc.(all regarding the the kidney aspect, but I wouldn't want to be in the shoes of any one of those people involved in these case studies) http://cjasn.asnjour...nt/2/4/757.full

L-Lysine Warnings
Last Updated: Aug 16, 2013

Lysine is an amino acid essential to human life. It can be obtained by eating animal protein, eggs, dairy products and beans. If you do not eat much of these foods, you may need to take supplemental lysine, which is often available in the form of L-lysine. L-lysine is generally thought to be safe, but it can be dangerous if you have certain conditions. You should always speak to your doctor before starting supplementation with lysine to avoid potentially problematic conditions and drug interactions.
Gallstone Formation
High doses of lysine have been found to cause gallstones. Lysine can increase your cholesterol. The increase in cholesterol can cause the bile in your gallbladder to retain excessive amounts of cholesterol, which can lead to stone formation. Take caution in using lysine if you have a history of gallstones or if your cholesterol is already high. Gallstones may not cause any symptoms. If they do, you will typically experience nausea, upper right-sided abdominal pain, vomiting and fever. If you develop gallstones, you may need to have your gallbladder removed.
Hypercalcemia
Taking lysine can increase your risk of developing hypercalcemia, abnormally high levels of calcium in the blood. This is especially true if you already take in a significant amount of calcium each day or if you have decreased kidney function. Lysine has been shown to increase the amount of calcium your intestines absorb, according to a review published in the November-December 1992 issue of "Nutrition." To decrease this risk, do not take lysine with a calcium supplement or with dairy products unless you're instructed to do so by your doctor. Consult your doctor immediately if you experience nausea, vomiting, flank or bone pain, muscle weakness or memory loss, as these are symptoms of hypercalcemia.
Kidney Disease
Lysine has been linked to kidney failure, so do not take it if you have impaired kidney function. Large doses of lysine and other amino acids may induce acute kidney failure even in healthy individuals, according to a review published in the June 2007 issue of "The Journal of Nutrition." Symptoms of acute kidney failure may include pain between the hip and ribs, a decrease in the amount of urine you're excreting, intractable nausea and vomiting, and bloody stools. Seek immediate help if you develop these symptoms while taking lysine.
Given that these issues mostly appear with large doses of amino acids, including lysine, it's apparent that one should not take large doses and observe the "everything in moderation" rule, even when it comes to Mother Nature. The risk seems minimal, however, but it's best to be aware of any risk when putting any foreign substance (including food) into the body.
What is a good "maintenance dose" of lysine, or how much do you take? I haven't studied the dosing yet. I've also heard about people using it with arginine. Can you shed some light on your own experiences with lysine?
