Brief Summary:
The study will assess whether Niagen, a safe dietary supplement, improves recovery of COVID-19 related symptoms in individuals who were infected at least 2 months prior to study entry ("Long-COVID" "Long-haulers"). 60% of participants will receive Niagen and 40% will receive PBO. Outcomes will consist of standardized cognitive, neuropsychiatric, physical, functional and biomarker assessments.

Condition or disease Intervention/treatment Phase
Covid19 Sequelae of; Infection Cognitive Symptom Drug: Niagen Phase 4

Detailed Description:

This study will recruit people who were infected with COVID-19 at least 2 months ago and continue to experience symptoms related to infection. Initially thought to be an acute illness like the flu, resulting in death for some or full recovery in most, scientists and clinicians are now appreciating that substantial numbers of COVID-19 illness survivors experience persistent, significant and sometimes disabling symptoms. Variously called "Long-COVID," "COVID long-haulers," or "chronic COVID syndrome", some of the most prominent symptoms are neurologic and neuropsychiatric, including cognitive impairment ('brain fog'), headache, fatigue, muscle aches and weakness, shortness of breath, hair loss and pain, among others. In this research study the investigators want to learn about whether taking Niagen (also known as Nicotinamide riboside, or NR), a daily supplement containing a form of Vitamin B3, can improve recovery of cognitive function, mood, and physical health in individuals who were infected with COVID-19 and continue to experience "brain fog" and other neurological and physical symptoms. The investigators think that this supplement may help improve thinking skills and other symptoms, and improve quality of life, in individuals who had COVID-19.

Participants will complete the following at baseline and every 5 weeks: 1) a standard cognitive battery and subjective cognitive complaints scales; 2) mood measures; 3) assessments of physical functioning, as well as of other common COVID-19-related symptoms; 4) blood draw; and 5) 2 optional MRIs. Participants will also wear a Fitbit and complete questionnaires to assess sleep and physical activity.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Examine the effect of Niagen on cognitive functioning as measured by executive functioning and memory composite scores. [ Time Frame: Baseline, 12 and 22 weeks ]
    The investigators will examine the effect of Niagen on cognitive functioning through neuropsychological test scores that form executive functioning and memory composite scores.


Secondary Outcome Measures :
  1. Examine the effect of Niagen in depression symptoms [ Time Frame: Baseline and every 5 weeks for 22 weeks ]
    Depression will be measured using the Beck Depression Inventory

  2. Examine the effect of Niagen in anxiety symptoms [ Time Frame: Baseline and every 5 weeks for 22 weeks ]
    Anxiety symptoms will be measured using the Beck Anxiety Inventory

  3. Examine the effect of Niagen in COVID-related physical symptoms [ Time Frame: Baseline and every 5 weeks for 22 weeks ]
    COVID-related symptoms will be measured using a COVID symptom checklist that assesses number and severity of symptoms.
