Vitamin B complex effective for cramps

Based on 2 Researches

Chan P, Huang TY, Chen YJ, Huang WP, Liu YC. Randomized, double-blind, placebo-controlled study of the safety and efficacy of vitamin B complex in the treatment of nocturnal leg cramps in elderly patients with hypertension. J Clin Pharmacol. 1998;38:1151.

We conducted a randomized, double-blind study to see if vitamin B complex could help older adults with nighttime leg cramps. Over three months, participants reported their cramp frequency and intensity.

The results were encouraging—86% of those taking vitamin B complex saw significant improvement, while the placebo group showed no notable changes. This suggests that vitamin B complex is a promising and safe alternative to traditional treatments like quinine, which can have unpleasant side effects.

NOW B-100 is effective! Since taking this supplement, the burning sensation in my legs with exertion has disappeared. My energy levels have increased, and my mood has improved over a couple of weeks. It's a great value, and the scent, although present, is not overpowering. The tablets are large, but swallowing them with another tablet makes it easier. I am a repeat customer and firmly believe in the benefits of B-100 for better health.

Vitamin B1 shows promising results

We assessed how effective oral vitamin B1 could be in treating primary dysmenorrhea, which causes significant pelvic pain in young women. In a robust study involving 556 participants aged 12-21 years, we administered 100 mg of vitamin B1 daily for 90 days.

The results were promising, with 87% of participants reportedly completely cured, while 8% experienced some relief. Notably, these positive outcomes persisted for two months after treatment ended, showcasing vitamin B1 as a safe and cost-effective approach to address the root cause of pelvic pain.

Benfotiamine improves ulcer healing

Based on 7 Researches

Shokati Sayyad M, Khanjani MH, Amirbeik M, Seyedabadi M, Talebpour Amiri F, et al. The protective effect of benfotiamine on gastric ulcers in male rats: an experimental study. J Mol Histol. 2024;55:863. doi:10.1007/s10735-024-10237-x

We investigated how benfotiamine might impact stomach ulcers in male rats. The study involved dividing 30 rats into groups receiving different treatments, including benfotiamine at varying doses, following the induction of ulcers using indomethacin.

Our results showed that benfotiamine notably decreased gastric damage and lowered inflammation markers. Specifically, doses of 100 and 200 mg/kg appeared to enhance antioxidant levels and reduce tissue damage.

However, while these findings are promising, more research is needed to fully understand the mechanisms at play and assess benfotiamine's potential for human treatment.

Great effect on acne! I initially took this for my health, but it significantly improved my acne. After two weeks, my skin was clear. I believe those struggling with rough skin should certainly try it. I've tried other vitamins, but this one proved most effective. I hope it helps! 😆

Hair Loss details

Cicaria shows promise against hair loss

Based on 5 Researches

Jo H, Kim SY, Kang BH, Baek C, Kwon JE, et al. Cicaria, a Novel Strain Derived from the Human Microbiome, and Its Efficacy as a Treatment for Hair Loss. Molecules. 2022;27. doi:10.3390/molecules27165136

We examined a new strain derived from the human microbiome, Cicaria, to see how it helps with hair loss. Through testing on individuals with hair loss and comparing them to a control group with normal scalps, we found that Cicaria produced key compounds like adenosine and biotin. Notably, hair follicles treated with these elements displayed longer lengths and maintained healthier root diameters. Furthermore, these treatments appeared to support the phases of hair growth, slowing the transition to hair loss. Thus, Cicaria shows potential as a treatment for hair loss.

Vitamin B12 effectively reduces pain

Based on 14 Researches

Mauro GL, Martorana U, Cataldo P, Brancato G, Letizia G. Vitamin B12 in low back pain: a randomised, double-blind, placebo-controlled study. Eur Rev Med Pharmacol Sci. 2000;4:53.

We sought to understand how intramuscular vitamin B12 could help alleviate low back pain in patients with mechanical lumbago. In a rigorous study involving 60 participants, we compared the effects of vitamin B12 to a placebo.

Our findings indicated that those receiving the vitamin reported significantly less pain and disability, as measured by a visual scale and disability questionnaire. Notably, those on vitamin B12 also used less paracetamol than the placebo group.

Overall, our study confirmed that vitamin B12 can be effective for treating low back pain without nutritional deficiency.

We explored the effects of vitamin B12 on a 33-year-old woman living with HIV, who faced severe vision loss due to optic neuritis, a rare outcome of vitamin B12 deficiency. Prior to this, she had battled significant peripheral neuropathy treated with vitamin B12 tablets. After starting vitamin B12 injections following her vision loss, she experienced gradual improvement and regained her sight. This case highlights the importance of recognizing vitamin B12 deficiency, particularly since its signs can easily go unnoticed.

Methylcobalamin protects against liver failure

Based on 4 Researches

Xu W, Wang Y, Cui S, Zheng Q, Lin Y, et al. Methylcobalamin protects against liver failure via engaging gasdermin E. Nat Commun. 2025;16:1233. doi:10.1038/s41467-024-54826-6

We investigated how methylcobalamin, a form of vitamin B12, affects liver failure, particularly in cases of cholestasis. Methylcobalamin showed promise as it directly binds to and inhibits Gasdermin E, a protein linked to liver cell death.

In mouse models, this vitamin significantly reduced liver inflammation and damage, lowering mortality rates. These findings suggest that methylcobalamin could be a potential treatment option for preventing severe liver failure and related health issues.

Bone Pain details

Carnitine aids bone pain relief

Tabei SM, Mazloom M, Shahriari M, Zareifar S, Azimi A, et al. Determining and surveying the role of carnitine and folic acid to decrease fatigue in β-thalassemia minor subjects. Pediatr Hematol Oncol. 2013;30:742. doi:10.3109/08880018.2013.771388

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.

B12 and folic acid show variability

Regland B, Forsmark S, Halaouate L, Matousek M, Peilot B, et al. Response to vitamin B12 and folic acid in myalgic encephalomyelitis and fibromyalgia. PLoS One. 2015;10:e0124648. doi:10.1371/journal.pone.0124648

We examined the effects of vitamin B12 injections, combined with folic acid, on 38 patients with myalgic encephalomyelitis (ME), also known as chronic fatigue syndrome.

Participants were split into "Good" and "Mild" responders based on their improvement. Good responders reported greater progress with more frequent injections and higher doses of both supplements.

However, for Mild responders, the improvement was limited, suggesting that while there is potential for benefit, the response can vary widely among individuals. Overall, further investigation is needed to explore optimal treatment strategies.

It’s essential to conduct a vitamin B test before ordering and follow a doctor's advice, as deficiency affects the nervous system. After experiencing tendon pain in my right arm, I switched to this product, which proved to be of excellent quality, despite a below-average taste. It may also change urine colour, but I hope it helps.
