Description
Quick answer: Puritans Pride Vitamin B6 100 mg is a high-dose vitamin B6 supplement. B6 supports energy metabolism, the nervous system and red blood cell formation, but there is an important catch: taking high doses such as 100 mg over a long period can cause peripheral nerve damage. It should be used cautiously and, for long-term use, under medical advice.
⚠️ Central safety rule: Taking high-dose vitamin B6 (such as 100 mg) for a long time can cause peripheral neuropathy — nerve damage causing numbness, tingling or pain, usually in the hands and feet. Do not take high-dose B6 long-term without medical advice, keep within recommended limits, and stop and see a doctor if you notice any numbness or tingling.

What is Puritans Pride Vitamin B6?
Puritans Pride Vitamin B6 100 mg is a supplement providing pyridoxine, one of the B-group vitamins, at a high 100 mg dose per tablet. Each bottle contains 100 tablets. Vitamin B6 is an essential nutrient with genuine roles in the body, but this is a high-dose product, and the most important thing to understand about it is the caution around taking high doses over time.
What vitamin B6 does
Vitamin B6 helps the body use energy from food, supports the normal function of the nervous system and the immune system, contributes to normal red blood cell formation, and is involved in making certain neurotransmitters. It is a nutrient the body genuinely needs — but, as with several vitamins, the amount needed each day is far smaller than a 100 mg tablet provides.
The important safety warning
This is the section that matters most. Unlike many water-soluble vitamins, vitamin B6 can cause harm when taken in high doses for a long time. Prolonged high-dose B6 is a recognised cause of peripheral neuropathy — damage to sensory nerves that causes numbness, tingling, burning or unsteadiness, typically in the hands and feet. According to the NIH Office of Dietary Supplements vitamin B6 fact sheet, there is an upper limit for B6 precisely because of this risk. A 100 mg tablet sits at a level where long-term daily use warrants real caution and, ideally, medical guidance.
How much B6 do you actually need?
The daily requirement for vitamin B6 is only a small number of milligrams, easily met by a normal diet. A 100 mg tablet provides many times that amount. High doses are sometimes used for specific, short-term medical reasons under supervision, but they are not something to take casually or indefinitely. Matching intake to need is especially important with this vitamin.
Who might be prescribed or advised high-dose B6
Doctors do sometimes recommend higher-dose B6 for particular situations, such as certain types of nausea in pregnancy or specific metabolic conditions, but this is done with guidance, a defined purpose and a time limit. Self-treating with a high dose for vague reasons, or continuing it for months and years, is where the risk of nerve damage arises.
Recognising the warning signs
If you take high-dose B6 and notice numbness, tingling, a burning sensation, clumsiness or unsteadiness — especially in the hands or feet — stop the supplement and see a doctor. Nerve symptoms from B6 often improve after stopping, but they are a clear signal that the dose is too high for too long. Do not ignore them or push through.
How to use it more safely
If you use a B6 supplement, favour keeping within recommended limits rather than taking a high dose routinely, take it with food, and avoid combining it with a multivitamin or B-complex that also contains B6, which can push your total intake higher than you realise. For any long-term use, involve a doctor who can weigh the reason against the risk.
Food sources of B6
Vitamin B6 is widely available in foods such as poultry, fish, potatoes, chickpeas, bananas and fortified cereals, so most people meet their needs easily through diet. Genuine deficiency is uncommon in people eating a varied diet. This makes routine high-dose supplementation unnecessary for the majority.
Storage and quality notes
Keep the bottle tightly closed in a cool, dry place away from direct sunlight, and out of reach of children. Check the expiry date and buy from a reputable retailer. Be mindful of the dose on the label and of any other supplements you take that also contain B6.
Expert note
Dr. Abdallah Fouad — Clinical Nutrition Specialist, 25+ years of experience: I want to be direct about this one, because it is different from most water-soluble vitamins. High-dose vitamin B6 taken over a long period can damage your nerves, causing numbness and tingling in the hands and feet — this is well documented. A 100 mg tablet is far above what you need from a normal diet. If a doctor has recommended high-dose B6 for a specific reason and time, follow their guidance; otherwise, do not take this dose long-term, watch for the total B6 in any multivitamins you also take, and stop and see a doctor immediately if you notice any numbness or tingling.
Frequently asked questions
Can vitamin B6 be harmful?
Yes, in high doses over a long time. Prolonged high-dose B6 can cause peripheral neuropathy — nerve damage causing numbness, tingling or pain in the hands and feet. This is why there is a recommended upper limit.
Is 100 mg of B6 a lot?
It is many times the daily requirement, which is only a few milligrams. High doses may be used briefly under medical supervision for specific reasons, but they are not for casual or indefinite use.
What are the warning signs to stop?
Numbness, tingling, a burning sensation, clumsiness or unsteadiness, especially in the hands or feet. Stop the supplement and see a doctor; symptoms often improve after stopping.
Who might need high-dose B6?
Doctors sometimes advise it for specific situations, such as certain pregnancy-related nausea or metabolic conditions, always with a defined purpose and time limit. It should not be self-prescribed long-term.
Do I need a B6 supplement at all?
Most people meet their needs through diet, from foods such as poultry, fish, potatoes, chickpeas and bananas. Genuine deficiency is uncommon, so routine high-dose supplementation is usually unnecessary.
