Lipoic Acid (1200mg daily) – this is the most important one. It gets into your damaged nerves and stops the burning from the inside. Most supplements only have 300-600mg, which isn't enough. You need 1200mg daily for it to actually work.
Benfotiamine (200mg) – this is a special form of B1 that protects your nerves from getting worse, especially if you have diabetes. It stops the progression so you don't end up with more damage.
B Vitamins (high-dose B12 as methylcobalamin) – your nerves need B vitamins to repair the protective coating around them. When that coating is damaged, you get tingling, numbness, and pain. B12 helps rebuild it so signals work properly again.
Acetyl L-Carnitine (100mg) – helps damaged nerve fibers actually regenerate. This is about healing, not just masking pain.
Turmeric (100mg) – reduces the inflammation around your nerves so there's less pain signals firing constantly.
You need all of them together at the right doses – not just one ingredient at fairy dust amounts like most supplements. That's why this actually works when other things don't.
