Yes, you can safely take Nervijen-D (which contains methylcobalamin + alpha-lipoic acid + benfotiamine + other B vitamins) together with cholecalciferol (vitamin D3) — in fact, this combination is very commonly prescribed in India for people with low vitamin D (your level 8.7 ng/mL is severely deficient) + nerve-related symptoms, fatigue, or general weakness.
Nervijen-D does not contain vitamin D, so there is no overlap or risk of overdose when combined with separate cholecalciferol. Taking only Nervijen-D would help with B12 and nerve support but would not correct your severe vitamin D deficiency — so both together is the better choice.
Next Steps
1. Start both after confirming with your doctor (especially since you are breastfeeding or have any other medicines/conditions) — but this combo is safe and standard.
2. Typical safe dosing (doctor will confirm/adjust):
• Nervijen-D: 1 capsule daily after food (usually at night)
• Cholecalciferol (vitamin D3): 60,000 IU once weekly for 8 weeks (then 2,000 IU daily maintenance) — brands like D-Rise, Uprise-D3, Calcirol, Lumia are fine
3. Add calcium 500–1,000 mg daily (e.g., Shelcal HD, Calcimax) — vitamin D works much better with calcium.
4. Recheck vitamin D after 8–12 weeks — aim for 40–60 ng/mL.
Health Tips
• Take vitamin D with a fatty meal (milk, curd, eggs, ghee) — absorption increases 2–3 times.
• Nervijen-D is best after dinner — helps with any nerve tingling/fatigue.
• Drink 2.5–3 liters water daily + 15–20 min safe sunlight exposure (arms/legs) — supports vitamin D.
• Avoid tea/coffee 1 hour before/after supplements — can reduce absorption slightly.
You are doing the right thing by correcting this severe deficiency early — most people feel significantly more energetic and less achy within 4–8 weeks.

You have a severe deficiency of Vitamin D.
The tablets like Nervigen have a very small amount of Cholecalciferol. So you should go for a regular Vit D3 supplement having 60 K vitamin D 3
