10 Popular Health Supplements

Here is a list of 10 popular supplements with their health benefit claims. 

Vitamin D:  An essential nutrient for bone health and immune function.

Multivitamins: A combination of vitamins and minerals that can help fill nutrient gaps in our diet.

Vitamin C: An antioxidant that helps support the immune system and may help reduce the severity and duration of colds.

Probiotics: Live bacteria that can improve gut health and may help with digestion, bloating, and diarrhea.

Magnesium: A mineral that is important for muscle function, blood pressure regulation, and energy production.

Fish Oil: A good source of omega-3 fatty acids, which are important for heart health, brain function, and inflammation.

CoQ10: An antioxidant that is involved in energy production in cells. CoQ10 levels decline with age, and some studies suggest that CoQ10 supplements may help improve heart health.

Turmeric: A spice that contains curcumin, a compound with anti-inflammatory and antioxidant properties. Turmeric supplements may help with arthritis pain and inflammation.

Melatonin: A hormone that helps regulate sleep-wake cycles. Melatonin supplements may be helpful for people with insomnia or jet lag.

Elderberry:  A fruit that has been used for centuries to treat colds and flu. However, the evidence for its effectiveness is mixed.

Review: Elderberry for Respiratory Illness, COVID-19 Infection.

A review by Dr. Susan Wieland of the University of Maryland School of Medicine and colleagues examined the use of elderberry for preventing and treating viral respiratory illnesses.

Background:

Elderberry has a long history of use for respiratory issues. During the COVID-19 pandemic, interest in elderberry supplements for preventing or treating the illness surged. However, concerns existed regarding elderberry potentially overstimulating the immune system and triggering a cytokine storm (an excessive immune response). Dr. Wieland's team aimed to assess the benefits and potential side effects of elderberry for these purposes.

Methods:

The researchers searched six databases, four research registries, and preprint materials, screening 1187 records. They identified five randomized trials on elderberry for treating or preventing viral respiratory illnesses. They found no studies linking elderberry to clinical inflammation issues, but three studies examined cytokine production after elderberry intake in a lab setting (ex vivo).

Results:

• The review suggested elderberry might not prevent the common cold but could potentially reduce its duration and severity. Similar findings were seen for influenza, although the evidence for both effects was considered inconclusive. (1)
• The researchers compared elderberry supplements to oseltamivir (an antiviral medication). They found that elderberry might be associated with a lower risk of influenza complications and side effects. However, evidence regarding elderberry and clinical inflammation outcomes was lacking. Interestingly, some evidence suggested elderberry might influence inflammatory markers, though this effect may diminish with continued use.
• A small study compared elderberry's effectiveness in reducing cytokines over time to diclofenac (an anti-inflammatory drug). The results suggested elderberry might be equally or slightly less effective than diclofenac. (1,2)

Additional Research on Potential COVID-19 Treatments

A separate review by Brett R. Martin and Joshua Richarson examined research articles from 2005 to 2021 on potential treatments for coronavirus infections. They focused on substances with anti-inflammatory, immune-stimulating, or antiviral properties, including vitamin D, zinc, vitamin A, elderberry, garlic, licorice, stinging nettle, N-acetylcysteine, quercetin, and selenium. Their findings suggested these substances might offer some benefit, but only vitamin D, zinc, licorice, quercetin, and selenium had research specifically related to COVID-19 effects. (3)

Five health supplements that have shown some promise on COVID-19

While there's been much interest in using supplements to combat COVID-19, it's crucial to understand that there is no magic bullet and supplements should not be considered a treatment or prevention method.

However, some research suggests certain nutrients may support overall immune health, which could potentially play a role in your body's response to the virus. Here are 5 supplements that have shown some promise, but remember:

1. Vitamin D: Deficiency is linked to increased susceptibility to infections. Studies suggest adequate Vitamin D levels might be associated with milder COVID-19 cases. However, more research is needed. (1)
2. Vitamin C: An antioxidant supporting immune function. While high doses haven't proven effective in treating COVID-19, ensuring adequate intake through diet or moderate supplementation might be beneficial. (2)
3. Zinc: Crucial for immune response and cell division. Studies suggest zinc deficiency might be linked to severe COVID-19 cases. However, excessive intake can be harmful, so consult a doctor before supplementing. (3)
4. Elderberry: Early research indicates potential antiviral properties against influenza and respiratory infections. Some studies suggest elderberry might shorten COVID-19 symptom duration, but more research is needed. (4)
5. Melatonin: This hormone regulates sleep and has antioxidant and anti-inflammatory properties. Some studies suggest melatonin might improve symptoms and reduce the risk of severe COVID-19, but more research is needed. (5)

• Always consult your doctor before starting any new supplement,
