Best I Ever Tried

"I am very happy with the quality of the ingredients used by Purolabs, and I can trust that their products and supplements are pure and mostly are natural extracts. And so far, Purolabs Vitamin B Complex are the best I ever tried."

Frequently Asked Questions

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.

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.

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.

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.

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).

    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.

    Niacin top up!

    Purolabs were recommended to me by a nutritionist as well as my partner! Great product, easy to swallow and I feel the additional niacin might help me in my fight to reduce cholesterol.

    Great product.

    Basic reason for purchasing to help with my flagging energy levels due to my hypothyroidism.

    I've been taking them for the last month and yes I have already noticed a change, particularly over the last week. Whereas in mid afternoon I would normally 'hit a wall' this no longer happens until early evening. Certain tasks I can now continue for longer periods before feeling a lag in energy too.

    One tablet daily gives 100%+ of all 8 minerals which cheaper brands don't do, also being made in UK I know they are safe (nothing added to bulk out or use for cheapness)

    Do they work? Yes.

    Will I continue to purchase? Yes.

    Would I recommend? Yes.

    Looking forward to optimising my energy.

    Simple to order, great service with a great product *****
