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.

Essential for immunity
My go-to source for Vitamin A. It’s essential for boosting immunity and fighting infections. I always use the NOW 25,000 IU version, which provides an adequate dosage easily, and I can increase it quickly if I sense a cold coming on without needing numerous daily servings.

Fish oil superiority
Vitamin A from fish oil surpasses that from Retinyl Palmitate. My husband and I have found fish oil far more satisfying for natural Vitamin A. We take it daily for prevention and increase the dose during infections. With Retinyl Palmitate, we experienced more frequent colds and infections than with the 25,000 unit fish oil. Thus, I believe fish oil Vitamin A effectively prevents and resolves mucous membrane infections and numerous other ailments.
