Vitamin A toxicity's impact on headaches
A Rare Case Report of Benign Intracranial Hypertension Caused by Hypervitaminosis A.
Insights on headache and vitamin A
We examined a rare case involving a 13-year-old girl who experienced symptoms of headache and visual disturbances due to benign intracranial hypertension (BIH) related to vitamin A toxicity. This condition was characterized by elevated pressure inside her skull, which led to her experiencing severe headaches, photophobia, and vomiting.

After conducting various tests, including magnetic resonance imaging and a lumbar puncture, we confirmed the diagnosis of BIH. Treatment was initiated with acetazolamide, a medication commonly used to reduce intracranial pressure. Although the study primarily focuses on the condition resulting from vitamin A excess, the use of acetazolamide makes it challenging to isolate the effect of vitamin A on headache relief specifically.

What's particularly noteworthy in this case is the significant elevation of serum vitamin A levels, which aligned with her symptoms. Following treatment, this patient showed a remarkable clinical improvement, including a reduction in papilledema during regular eye check-ups. Within just two weeks after starting treatment, she was discharged symptom-free, highlighting how important it is to consider vitamin A levels in children presenting with similar symptoms.

This case serves as a reminder for clinicians regarding the potential consequences of vitamin A toxicity, especially when evaluating children with headaches correlated to papilledema.

Potential headache trigger
After using this product, I experienced a severe headache, possibly due to the soybean oil and PUFA (polyunsaturated fatty acids) it contains, which are said to cause chronic inflammation and harm health.

Headaches alleviated
Good composition, fast delivery, high-quality packaging, and nothing was damaged. The capsules are a tad large but easy to swallow. I've taken one daily for 10 days and noticed more energy, stopped headaches, and improved mood. I recommend it, especially for those interested in sports or on a diet. Omega-3 energises and replenishes what the body lacks.

Reduced headache frequency
I mistakenly took two capsules in two days, resulting in headaches. I've since reduced it to one a week and have no more headaches.
