What are Soya Isoflavones? 

Soya is the best source of Phyto (plant-based) Oestrogens, and is rich in three particluar Isoflavone compounds: Daidzin, Glycitin and Genistin.

Why take Soya Isoflavones? 

The onset of the menopause brings natural production of oestrogen down to much lower levels than a woman is used to. This change will often result in discomfort by way of hot-flushes, night-sweats, moods-swings and irritability - all uncomfortable effects that are usually treated by the introduction of additional oestrogens into the body through HRT or supplementation. These oestrogens can help to combat this crash, and restore balance to the bodies hormones.

Guaranteed strength and quality per tablet - the UK's strongest

Just Vitamins Soya Isoflavone tablet is produced using a 250mg Soya complex, which is standardised to provide 40% of its mass as isoflavones, giving 100mg of actual Soya Isoflavones per tablet - this is more than double the level of most other retailers.

Product: I was recommended this supplement by my GP, as I am going through the menopause , but due to illness cannot take HRT or estrogen, so was recommended soya isoflavones. I have been talking them for 3 weeks and just started my period again and the symptoms I was suffering have definitely eased a bit and I feel less tired. I was a bit sceptical that anything would work but I am very happy with them and will continue taking them. Would recommended giving them a go if you are in a similar situation.

Product: Maybe too early to be 100% sure but I believe that they're helping to alleviate my symptoms
Service rating: Have purchased this supplement for my wife for several years, it seems to really help for post menopausal symptoms. Gave 4 stars because it seems that Just Vitamins have dropped the 180 sized package of this supplement so could only order the smaller 90 which effectively represents a price increase. Did send an email to Just Vitamins but never got an answer.
Product: After trying various post menopausal supplements, this one really suites my wife
Service rating: Always good to buy from this seller, never a problem. Well packaged orders that arrive safely. Good varied choice of vitamins, would recommend.

Service rating: The test of good company is how they deal with errors/ reward loyal customers. I am very pleased to say that 'Just Vitamins' customer service demonstrates how highly they value their customers and how quickly and painlessly they rectify mistakes. 100% recommended!
Product: Really difficult to say whether this product 'works' or not - I'd only be able to tell if I stopped taking it or was given a placebo. However, I have no symptoms of hot flushes etc and no side effects so will continue to take it.
Service rating: quick, efficient, fair prices, lots of choice
Product: I'm taking them as going through the menopause, and found that I don't have as many and as bad sweats

Product: Supplement fine,though tablet a little large to swallow easily and you need to get it done first go or coating becomes rough and tablet tastes foul
Service rating: Very happy they came promptly and was kept informed
Product: Only just started taking them so don’t know if they will help with the menopause
Service was excellent. I bought the soya isoflavones for menopausal symptoms and they do seem to have helped with low mood. Also got some collagen tablets but can’t say weather they are doing anything or not!

Product: Find them very good for hot flushes. Really work have tried different options.
I have used Just Vitamins for a number of years and buy 6 different products from them regularly. The products are excellent and competitively priced. The free postage option is great and so is the letterbox-friendly packaging (which is also recyclable). I recommend Just Vitamins to anyone who asks where to get supplements from. I can’t yet say whether the Soya Isoflavones are effective as I haven’t been taking them long enough
Service rating: Quick and efficient, good value for money.
