Effect of a Locally Formulated Carrot–Ginger Micronutrient Supplement on Immunological and Liver Function Biomarkers among HIV Patients Receiving Antiretroviral Therapy in Kaduna State, Nigeria

Living with HIV requires more than just medication; it demands a body that is strong enough to fight back. For decades, doctors have known that the virus attacks the immune system, specifically a type of white blood cell called the CD4 T-cell, which acts as the general of the body's defense force. When these cells are depleted, the body loses its ability to ward off infections. While modern drugs known as antiretroviral therapy, or ART, are excellent at stopping the virus from multiplying, they do not always fully restore the immune system on their own. In many parts of the world, patients also struggle with a lack of essential vitamins and minerals, a condition known as micronutrient deficiency. These tiny nutrients, such as vitamins A, C, and E, along with minerals like zinc and selenium, are the fuel the immune system needs to rebuild itself. Without them, the recovery process can be slow and incomplete. Furthermore, the very drugs used to treat HIV can sometimes cause stress to the liver, the organ responsible for filtering toxins from the blood. This creates a difficult situation for patients in resource-limited settings: they need better nutrition to heal, but expensive commercial supplements are often out of reach.

In response to this challenge, a team of researchers in Kaduna State, Nigeria, set out to test a simple, local solution. They wondered if a mixture made from two common kitchen ingredients—carrots and ginger—could help HIV patients recover their immune strength and protect their livers. Carrots are naturally rich in beta-carotene, which the body converts into vitamin A, a nutrient vital for immune function. Ginger contains compounds known for reducing inflammation and supporting liver health. The researchers hypothesized that combining these two foods into a daily supplement might offer a low-cost way to boost the effectiveness of standard HIV treatment. To find out, they conducted a carefully controlled study involving ninety adults living with HIV who were already taking their daily medication. The participants were divided into three groups. One group continued with their medication alone. A second group took their medication along with a well-known, commercially produced vitamin and mineral supplement. The third group took their medication alongside a locally made powder made from dried carrots and ginger mixed in a specific ratio.

The study took place over ninety days at a general hospital in Kafanchan. The researchers measured the health of the participants at the start and then checked their progress every thirty days. They looked at several key indicators: the number of CD4 T-cells in the blood, the levels of vitamins and minerals in the serum, the patients' body weight, and the levels of enzymes that signal liver stress. The results showed a clear difference between the groups. By the end of the three-month period, the patients who received the carrot-ginger supplement saw a significant rise in their CD4 T-cell counts. Their immune cells increased from an average of about 373 cells per microliter at the start to roughly 402 cells per microliter. While the group taking the commercial supplement saw an even larger increase, reaching nearly 477 cells, the improvement in the carrot-ginger group was still substantial and statistically meaningful compared to the group that received only the medication. The group with no supplement showed very little change in their immune cell counts, suggesting that the medication alone was not enough to fully restore their immune strength in this short timeframe.

Beyond the immune system, the supplement also had a positive effect on the patients' overall nutrition and liver health. The patients who took the carrot-ginger mixture gained weight, moving their body mass index into a healthier range, which is a critical sign of recovery for those who have suffered from HIV-related weight loss. Their blood tests revealed higher levels of essential vitamins and minerals, particularly vitamin A, vitamin C, and zinc. Perhaps most importantly, the supplement appeared to protect the liver. In the group that took only the medication, the levels of liver enzymes, which rise when the liver is under stress, increased slightly over time. In contrast, the groups receiving supplements, including the carrot-ginger mixture, maintained stable or even slightly reduced levels of these enzymes. This suggests that the natural compounds in the ginger and carrots helped shield the liver from the strain of processing the daily medication.

The researchers also looked at how these different factors were connected. They found a very strong link between the levels of vitamins in the blood and the number of immune cells. Patients with higher levels of vitamin A, vitamin C, and minerals like zinc and selenium tended to have higher CD4 counts. This correlation supports the idea that providing the body with the right nutritional building blocks helps the immune system rebuild itself more effectively. The study concluded that a locally formulated supplement made from carrots and ginger can serve as a valuable, low-cost addition to standard HIV treatment. It helped improve immune recovery and supported liver function without causing any serious side effects. While the commercial supplement performed slightly better in some measures, the local mixture offered a powerful, accessible alternative for patients in areas where expensive products are not available. The findings suggest that for many people living with HIV, the path to better health may lie not just in the pharmacy, but also in the kitchen.
