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.

Quick recovery noted
Fine! I truly appreciated this natural beta carotene. I took it myself and also gave it to my husband at the first signs of a cold, and his recovery was rapid! The benefits are evident. The capsules are small, soft, and easy to swallow, and the packaging is convenient, taking up little space in the refrigerator. NOW Foods products consistently demonstrate high quality.

Helps with sore throat
I take Vitamin C, Zinc, and Vitamin D3 & K at the onset of a cold, along with this. When I experience a sore throat, this aids my recovery significantly, making it a very useful addition to my regimen.

Effective for prevention
This is effective for preventing colds in the throat and nose. During the air-conditioning season in summer and cold winter, I often suffered from pharyngitis and acute sinusitis. I discovered that this ingredient strengthens mucous membranes, so I began taking it daily, and I hardly get a cold in my throat or nose anymore. Compared to before, when the conditions worsened, I find it distinctly effective.

Supports skin health
This is a fantastic supplement for skin health and immunity! I have been using beta-carotene for several weeks now and have noticed positive changes. My skin appears healthier and more radiant, particularly on sunny days. Additionally, I feel more resilient against colds and infections. The capsules are easy to swallow and the ingredients are natural, which is essential for me. I recommend it for anyone looking to enhance healthy skin and immune function!

Clear skin improvement
I liked the drug immensely. It absolutely works! I experienced a lack of vitamin A - there were vivid pink spots on my thighs, reminiscent of cold weather, which were palpable and visible, similar to "goose bumps". However, after taking this carotene along with vitamin E, everything has cleared up!
