Positives

• A patient taking Tru Niagen alongside LDN found that NR made the LDN more effective, with stopping NR on multiple occasions resulting in more pronounced fatigue while continuing LDN alone Reddit.
  
  
• A long-hauler reported feeling better on high doses of B1 and Nicotinamide Riboside, with general improvement across many symptoms Reddit.
  
  

Negatives

• A long-hauler had difficulty tolerating large quantities of Niagen and had to reduce from standard dose to 250mg with more time between doses, with still no sustained improvements Reddit.
  
  

Hurdles & Side Effects

• Tru Niagen runs about $40-$50 for a 30-day bottle of 300 mg capsules, and patients trading notes on NAD boosters show disabled members on fixed income switching to bulk NR powder from AliExpress at roughly one-tenth the price because branded Niagen is unaffordable long-term, while ConsumerLab’s testing found most generic NR products contained little to no actual NR Phoenix Rising.
