We examined the potential benefits of carnitine and folic acid in reducing bone pain and fatigue in patients with beta-thalassemia minor. Over three months, 73 participants received either carnitine alone, a combination of carnitine and folic acid, or folic acid alone, while a control group went without supplementation.
Our results showed that carnitine significantly improved plasma levels and reduced bone pain and muscle weakness for those affected by this condition. Although folic acid improved red blood cell levels, its impact on bone pain was not directly highlighted. Overall, our findings suggest that carnitine can be beneficial in addressing bone pain in these patients.

Initially thought a high dosage of B vitamins was beneficial, but I experienced dark yellow urine, pain in my bladder, strong weakness, and eventually liver pain. I regretted taking these vitamins thoughtlessly.

I'm very pleased with this product. The Solgar B complex is easy to swallow and I've found it effective. I suffered from fatigue and poor sleep, but they’ve improved since taking these vitamins. Additionally, my hair has stopped falling out, and I've noticed improvements in bone pain and my heart. It's an excellent support for the body during stressful periods, and there are no allergies or issues. I will definitely repurchase this complex.

Boosted energy levels
4 people found this helpful
For a long time, I suffered from impotence and lethargy, resulting in bone pain. I discovered a lack of B vitamins and ordered Solgar’s, which are high quality. Within a week, my energy increased, as did my motivation. I stopped feeling tired and my back pain diminished. My mood improved significantly too, although I had a flu episode. I believe multivitamins are essential for boosting immunity before continuing B vitamins.

Less joint pain
3 people found this helpful
I was anxious about joint pains and headaches, which led to a depressive state. After a week of taking these vitamins, I noticed joint pain decreasing and mood swings disappeared. I feel energised, and these Solgar vitamins support heart and nervous system health. They contain no wheat or dairy products and are gluten-free. The quality is exceptional, and I wish everyone good luck with their health.

Stronger nails

I must note that the dosages in this complex are therapeutic, making it more of a medicine than a vitamin. After a month of use, my neck pain subsided, and I also noticed stronger nails and improved hair growth. Good product; I will continue taking it.

Increased energy

I have hypothyroidism and have found that taking these vitamins has alleviated my body pain considerably; I even managed to go shopping! However, missing doses leads to a return of symptoms and body pain. Consistency is key.

Reduced bone pain
11 people found this helpful
Great anti-inflammatory! I mainly use this product for my joints. As someone who is overweight and has arthritis, I often experience bone pain. This B complex formula from Solgar significantly reduces inflammation and pain, especially in my knees. I take it with flaxseed oil, which almost eliminates the pain entirely. I prefer this natural alternative to OTC pain relievers, as I believe they harm your liver or kidneys. The 100 B complex lasts longer too!
