Inclusion criteria

* Adults 18 years and over * Able to provide informed consent * Diagnosed with COVID-19 infection (RAT or PCR test) \>4 weeks, but \< 12 months and experiencing post COVID symptoms (1) * Agree not to participate in another clinical trial while enrolled in this trial 1. Common post COVID symptoms may include fatigue, cough, chest pain, hair loss, weakness, joint pain, cardiac issues, neurocognitive impairment including memory loss, and decreased quality of life

Exclusion criteria

* Symptoms resulting from vaccination (2) * Unstable or serious illness (e.g., serious mood disorders, neurological disorders such as MS, kidney disease, liver disease, heart conditions, diabetes, thyroid gland dysfunction) (3) * Current malignancy (excluding BCC) or chemotherapy and radiotherapy treatment for malignancy within the previous 2 years * Receiving/prescribed coumandin (Warfarin), heparin, dalteaparin, enoxaparin or other anticoagulation therapy * Receiving pharmaceutical treatment for anxiety, libido, low energy * Active smokers, nicotine use, alcohol, or drug (prescription or illegal substances) abuse * Chronic past and/or current alcohol use (\>14 alcoholic drinks per week) * Allergic to any of the ingredients in the active or placebo formula * Known pregnant or lactating women * Any condition which in the opinion of the investigator makes the participant unsuitable for inclusion * Participants who have participated in any other related clinical study during the past 1 month * History of infection in the month prior to the study (2) Symptoms must be as a direct result of having contracted COVID. If symptoms only appeared within 2 weeks of a vaccination it will be considered a vaccine injury and not classed as a result of COVID. (3) An unstable illness is any illness that is currently not being treated with a stable dose of medication or is fluctuating in severity. A serious illness is a condition that carries a risk of mortality, negatively impacts quality of life and daily function and/or is burdensome in symptoms and/or treatments.

Design outcomes

Primary

MeasureTime frameDescription
Change in Energy and FatigueBaseline, week 4, week 8 and week 12Change in energy and fatigue as measured via Fatigue Severity Scale. The items are scored on a 7 point scale with 1 = strongly disagree and 7= strongly agree. The minimum score = 9 and maximum score possible = 63. Higher the score = greater fatigue severity

Secondary

MeasureTime frameDescription
Change in Mental AcuityBaseline, week 4, week 8 and week 12Change in Mental acuity as measured by Reaction Time Test
Change in Muscle Strength (Hand grip)Baseline, week 4, week 8 and week 12Change in Muscle Strength (Hand grip) as measured by Dynamometer
Change in Hair loss/growthBaseline, week 4, week 8 and week 12Change in Hair loss/growth as measured by Hair loss questionnaire
Change in LibidoBaseline, week 4, week 8 and week 12Change in Libido as measured by - If male, DISF-SR (Derogatis Sexual Function Index), If female, FSFI (Female Sexual Function Index)
Change in Stress and MoodBaseline, week 4, week 8 and week 12Change in Stress and Mood via Depression Anxiety and Stress Scale (DASS-21)
Change in MemoryBaseline, week 4, week 8 and week 12Change in Memory as measured by Short Term Memory testing
Change in Pathology results via Blood testBaseline, week 4, week 8 and week 12Change in Pathology results (Full blood count, CRP, iron, Soluble P-selectin, Testosterone, DHT, SHBG, Estrogen, IGF1, Cortisol, Prostaglandins, Inflammatory markers IL-10, IL-6, IL-17, TNF-a) as measured by Blood test
Change in WeightBaseline, week 4, week 8 and week 12Change in Weight as measured by scales in kg
HeightBaseline, week 4, week 8 and week 12Height as measured by tape measure in centimetres
Change in Safety as assessed by Adverse Events RecordingDuring enrolment periodChange in Safety as assessed by Adverse Events Recording
Change in safety markers as assessed by pathologyBaseline, week 4, week 8 and week 12Change in safety markers E/LFT as assessed by pathology
Change in Quality of Life IndicatorsBaseline, week 4, week 8 and week 12Change in Quality of Life Indicators via Symptom Burden Questionnaire - Long Covid
