Frequently Asked Questions

Can I take this with your other products?

Yes, this product has been formulated to work in partnership with other products in our range.

Many customers choose to pair this product with Puro Multivitamin - our comprehensive daily formula with 34 premium ingredients for complete daily support.

If you have any concerns or a medical condition, please speak with a member of our team or consult your GP.

How do I know this is a quality product?

This product is made in the United Kingdom to GMP standards in an ISO 22000 certified facility. It's also rigorously tested for purity & ingredient quality - and we stand behind it with a 60 day money back guarantee.

How long until I feel benefits?

B-vitamins are water-soluble meaning they constantly need to be replenished in the body so a consistent and regular intake is often beneficial.

The results will vary from person to person but the beneficial effects of B vitamins tend to build up over several weeks.

Some customers report feeling a difference in 3-4 weeks, but it can take up to 12 as we're all unique and different.

Why are B vitamins important for vegans?

Many of the B vitamins inside a vitamin B-Complex are commonly obtained from animal-based sources - particularly red meat.

This can mean anyone following a plant-based diet may be at an increased risk of deficiency.

Puro B Complex is 100% suitable for both vegans & vegetarians.

Does this product contain all B vitamins?

Yes. This product contains over 100% of the recommended daily allowance for all eight essential B vitamins - B1, B2, B3, B5, B6, B7, B9 &; B12 plus we also include PABA (vitamin B10).

What makes your product better?

We include B vitamins in clinically-backed doses that really make a difference & use superior quality forms of B vitamins including methylcobalamin B12 to ensure ultimate absorption & effectiveness.

Unlike most supplements we also don't include hidden nasties like synthetic additives, bulking agents and fillers.

    Energy Boosting

    I was so fatigued earlier this year and following testing for deficiencies, my results highlighted I was low in several B vitamins. I did my research to find a suitable supplier that used natural ingredients and no fillers or additives in their supplements. Purolabs was a company I had used in the past for their menopause supplements and I chose to buy from them again. Within a week or so of taking the B Complex, I was feeling much more energised and the vitamins have made a huge difference to my health and life balance. I have a subscription to ensure I don't run out and have now got my 90 year old father started on the B Complex which he feels have helped his energy levels which is important as he has a limited diet these days. Highly recommend.

    Vitamin B Complex

    Arrived quickly in a small compact box that goes easily through your letter box so no need to be there when they are delivered. I've only been taking them for a month but I think my hair has improved. I will be buying them again.
