For addressing extreme depression, evidence on supplements is limited and generally supplements should not replace conventional treatments like therapy or prescribed medication. That said, some people find that certain supplements, like Omega-3 fatty acids, St. John's Wort, and S-Adenosyl methionine (SAMe), might help support mood health. However, it is strongly recommended to consult a healthcare professional before using such supplements, as they can interact with medications and have side effects.

When it comes to managing symptoms of the common cold, several supplements have been found to be potentially beneficial:

1. Vitamin C - Regular supplementation of 1 to 2 grams per day might reduce the duration and severity of the common cold¹.
2. Zinc - If taken within 24 hours of the onset of symptoms, zinc can reduce the duration and severity of colds²³.
3. Vitamin D - Supplementation may provide protective effects, especially for individuals with a deficiency¹.
4. Echinacea - Some studies suggest that taking Echinacea may help prevent and treat colds, though results can vary¹.

As always, it is important to consult with a healthcare provider before starting any new supplement regimen, especially if you have underlying health conditions or are taking other medications.
