Vitamin A's key role in thermogenesis
Intact vitamin A transport is critical for cold-mediated adipose tissue browning and thermogenesis.
Highly relevant to metabolism research
We explored how vitamin A affects our body’s response to cold, specifically looking at its role in transforming white fat into brown fat, a process known as browning. This transformation is significant, as it can help reduce obesity and improve metabolic health.
In our investigation, we conducted cold exposure studies involving both mice and humans. We observed that exposure to cold led to an increase in circulating vitamin A, also known as retinol, and its transporter protein, Rbp. However, in mice lacking this protein, we found that their ability to adapt to the cold and promote thermogenesis—essentially, generating heat through fat—was severely compromised.
Interestingly, we also noted that stimulating human fat cells with retinol heightened the expression of genes associated with thermogenesis and boosted mitochondrial activity, which is vital for burning fat. In humans, the rise in vitamin A during cold exposure hinted at improved fat utilization.
Overall, our findings revealed that not only are vitamin A levels responsive to cold, but effective transportation of this vitamin is crucial for cold-induced fat browning and the body's ability to generate heat.

Effectiveness of Vitamin C on Colds
Vitamin C for the common cold and pneumonia.
Strong relevance to cold prevention
We explored the effects of vitamin C on the common cold and pneumonia by examining a range of studies. Interestingly, research on animals suggests that vitamin C may have protective effects against infections. However, when it comes to preventing colds in the general population, taking more than 1 gram of vitamin C per day didn’t show significant benefits.
But there's a twist! Participants engaged in heavy physical activities saw their cold incidence reduced by half with vitamin C supplementation. Additionally, regular intake of 1 gram or more daily was linked to a 15% decrease in cold severity. While some therapeutic trials showed inconsistent results when vitamin C was taken after cold symptoms appeared, two studies did indicate that larger doses (6-8 grams per day) could effectively shorten the duration of colds compared to lower doses.
Our investigation also looked into pneumonia, but the studies were conducted in unique settings, such as a boarding school and military recruits. This makes it hard to generalize the findings to the wider population. Yet, some trials suggested benefits for pneumonia patients. Finally, the role of vitamin C in treating COVID-19 and sepsis remains unclear, with mixed results.
Given that vitamin C seems to alleviate symptoms and shorten the duration of colds, while being safe and affordable, it might be worth considering a dose of 6-8 grams per day to see if it helps at an individual level.

Vitamin C improves cold tolerance
Application of Exogenous Ascorbic Acid Enhances Cold Tolerance in Tomato Seedlings through Molecular and Physiological Responses.
Directly addresses cold tolerance
We explored the effects of ascorbic acid, commonly known as vitamin C, on cold tolerance in tomato seedlings. In our study, we discovered that applying vitamin C significantly boosts the seedlings' ability to handle cold stress.
By enhancing the antioxidant defense system, vitamin C treatment increased the enzyme activity in the seedlings' leaves. Additionally, it raised levels of important compounds such as proline, sugar, and abscisic acid, all of which play crucial roles in plant stress responses.
Our observations showed that vitamin C also protects the photosynthesis system of tomato seedlings. This implies that it helps maintain chlorophyll function, which is critical for the plant's overall health, especially under cold conditions.
Moreover, we found that vitamin C treatments led to increased expression of genes linked to antioxidant enzymes and cold response mechanisms. Overall, our findings suggest that exogenous vitamin C is a beneficial approach to improve cold tolerance in tomatoes and may provide helpful insights for farmers looking to cultivate hardier varieties during colder months.

Boosts overall health
I've been using supergreen products for about two years and switched to Garden of Life six months ago. My overall health has improved significantly, and I haven’t caught a cold in over two years, even when surrounded by illness. My digestion feels optimal, and I have energy to spare, a stark contrast from five years ago. These products have worked wonders for my health.

No more colds
Really helped me and my weak immune system. I have a poor immune system and suffer from colds or flu several times a year. I've been using this product for over a year now and haven't contracted any contagious diseases—no colds, no flu. I would recommend this to anyone with a weak immune system.
