Vitamin A deficiency worsens lupus nephritis
We examined the impact of vitamin A deficiency (VAD) on the progression of lupus nephritis in a mouse model. By inducing VAD during pregnancy or after weaning, we discovered that both methods significantly worsened the condition, leading to higher mortality rates.
Interestingly, restoring vitamin A levels after weaning reduced mortality. This suggests that VAD accelerates lupus nephritis through increased immune cell activation and autoantibody production. However, effects were less pronounced when VAD was introduced post-weaning. Overall, the study highlights the potential dangers of vitamin A deficiency in autoimmune diseases.

We analyzed data from five cycles of the National Health and Nutrition Examination Survey (NHANES), focusing on how dietary retinol (a form of vitamin A) intake relates to rheumatoid arthritis (RA).
Our findings indicated that higher dietary retinol intake, especially in women, was linked to a reduced risk of developing RA. Specifically, women who consumed more than 354.86 mcg of retinol saw the most significant benefits.
This suggests that adjusting our diets to include more vitamin A could offer a protective effect against this autoimmune disorder.

We investigated whether a therapeutic vaccine could target harmful Th17 cells in autoimmune diseases using vitamin A ingredients. By using all-trans retinoic acid (ATRA) in liposomal formulations, we found that it specifically inhibited Th17 cells related to a particular autoantigen, sparing unrelated ones.
This process not only reduced disease severity in a mouse model of multiple sclerosis, but also encouraged Th17 cells to adopt a more regulatory and tolerant role. Overall, our findings suggest that ATRA-containing vaccines might effectively alter the behavior of Th17 cells in autoimmune conditions.

Seizures alleviated
180 people found this helpful
I took vitamins daily and noticed significant improvement after three days, achieving mostly normal mouth movement. After a week and a half, the seizures disappeared—though results can vary for others. I now take these vitamins in courses at the start of cold weather and in spring, and the issue with seizures no longer bothers me. I highly recommend purchasing these vitamins if prescribed by a doctor; you certainly won't regret it.

Skin condition improved
7 people found this helpful
I took this drug primarily as a co-factor of vitamin E. Alongside Mason Natural Vitamin E, this dietary supplement restored my extremely dry skin to a normal condition quite quickly! I took both in tandem during the autumn-winter period when the heating in our house dries the air, causing my skin to crack and peel. After a month, everything improved, and I continue taking them. I plan to order vitamins A and E from these brands again in the autumn due to their good formulation, volume, and value for money.

For years, I struggled with problematic skin since my teens. After trying various treatments, I ordered vitamin A to specifically address my skin issues. A month later, my skin feels smoother, the pores have tightened, and overall, I was pleasantly surprised. I did not experience any side effects and plan to continue using it.

Vitamin A enhances rheumatoid arthritis treatment
We examined how well all-trans retinoic acid (ATRA) works alongside methotrexate (MTX) in treating rheumatoid arthritis. Our research focused on its ability to reduce the growth of synovial cells while promoting their death, which is essential in managing this condition.
While MTX alone didn't significantly affect cell viability or apoptosis, the addition of ATRA showed impressive results. It not only inhibited cell growth but also triggered both apoptosis and autophagy via the ROS-JNK pathway. In tests with rats, this combination therapy notably improved results compared to MTX alone.
ATRA may be a valuable supplementary treatment for rheumatoid arthritis, especially since MTX alone has limited effectiveness on these specific cellular processes.

We explored an innovative treatment for autoimmune arthritis using microparticles that release all-trans retinoic acid (ATRA), a form of vitamin A. This method aims to enhance immune responses in a targeted way, improving T cells that help reduce inflammation.
Our findings show that these microparticles, when injected into the joints of mice, decreased symptoms of the disease without completely suppressing the immune response. The approach appears promising for enhancing treatment in patients who don’t respond well to traditional therapies like DMARDs.

We investigated a cutting-edge method using engineered nanoparticles to deliver all-trans retinoic acid (ATRA) directly to synovial fibroblasts in rheumatoid arthritis (RA). This approach utilizes a unique Golgi-targeting system to ensure effective treatment.
Our findings demonstrated that ATRA-loaded nanoparticles significantly disrupted pathogenic protein production in RA cells, leading to less inflammation and reduced joint damage in animal models. Overall, this targeted delivery method shows promise in effectively managing RA while being mindful of safety, as it caused minimal toxicity to major organs.

Rapid healing effects

I took this alongside vitamin E during my rubella period to reduce peeling from the rash, and it helped. Although the formulation isn't the most natural, I noticed improvements within five days, quicker than the usual Aevit from the chemist. My grandmother also took it a couple of times yearly, but now I'm searching for a more natural alternative.

Now Foods' products are of very high quality. I ordered vitamin A, and to my surprise, I noticed benefits within just three days; a scar on my hand vanished. After the first course of treatment, I reordered and plan to share it with my son as well. The tablet size is manageable and taste-free. I highly recommend everyone to try it!

Improved eyesight noted
2 people found this helpful
I noticed my eyesight deteriorating from working at the computer and mobile internet usage. I ordered vitamin A, initially sceptical about its effectiveness. However, after three to four weeks, I observed significant improvements. My eyes feel less fatigued, and clarity has noticeably improved. I'll finish the course and, if necessary, order more.

Skin problems resolved
2 people found this helpful
I ordered it for my little sister, who had dry, cracked skin. She now says it has cleared up. It's important to remember that this is a fat-soluble vitamin that can accumulate in the body, so moderation is essential; no overdosing is key. I also combined it with omega-3.

Skin condition improved
143 people found this helpful
I have suffered from atopic dermatitis and eczema since childhood. After switching from pharmacy vitamins to those from iHerb, my skin condition improved significantly. I take capsules for a month, followed by a month off to prevent vitamin A overdosing. I recommend checking your vitamin A levels with a test to adjust dosage accurately. If you're pregnant, avoid vitamin A due to teratogenic risks. If my experience has helped, please give it a thumbs up!

Vitamin A is superb and well-received by my family. We take it in the evening to avoid interaction with other supplements. Together with vitamins E, D, and omega, it manages acne and skin conditions effectively. I consume it regularly for my autoimmune condition.
