I've been taking Nutracene Ashwagandha KSM-66 for a few days now, and I’m genuinely impressed with the results. Right from the start, I appreciated the clean and transparent labelling, and knowing it's made in the UK with vegan-friendly ingredients gave me confidence in the quality. The high strength 1,000mg dose, combined with black pepper for better absorption, really sets this supplement apart from others I’ve tried. I’ve noticed a definite improvement in my ability to stay calm under pressure, especially during busy workdays.What I really love is that this supplement doesn’t make me feel drowsy or sluggish—quite the opposite. I’ve felt more clear-headed and energised throughout the day without any crash. It’s helped me manage stress more effectively, and I feel like my overall mental resilience has improved. Nutracene has done a fantastic job with this product, and it’s now a staple in my daily routine.

High Quality with Room for Improvement
I've been enjoying the benefits of Ashwagandha for over a year now, and I decided to try these Nutracene Ashwagandha capsules because they use only vegan ingredients and are free from unnecessary bulking agents or fillers.The Ashwagandha KSM-66 arrived in a white plastic jar, securely sealed with two tamper-proof seals and a child-proof lid. Unfortunately, the capsules inside only fill about half of the container, which I find both a bit misleading and wasteful in terms of packaging.This product is manufactured in the UK by Novogen Labs, based in Oxford. In addition to KSM-66 Ashwagandha Root Extract, it also contains black pepper powder and a vegetarian capsule shell.The label reassures customers by stating that the product adheres to GMP standards and is both GMO- and gluten-free. The recommended daily dose is two capsules, which I’ve found to be easy to swallow and completely tasteless. The bottle contains 120 vegan capsules, providing about a two-month supply.Overall, I feel confident that this is a high-quality product. However, I would have preferred a more appropriate packaging design so that the tablets filled the container completely.For transparency, I want to clarify that I am under no obligation regarding what I can or cannot write. I always leave honest and unbiased reviews, whether they are positive or negative.Thank you for reading my review. I hope you find it helpful!

What Our Happy Customers Are Saying
Experience enhanced energy, better immunity, and overall well-being with every dose.
Life's busy and a bit full-on at times, but this seems to take the edge off…. It’s a high-strength formula, but gentle on the stomach, no odd aftertaste or side effects, which I’ve had with other supplements before. The added black pepper helps with absorption too, so you’re getting the most out of it.

"I'm quite picky about the country of origin of any product that I will ingest. I much prefer products from the UK, western Europe, North America, and a few other countries such as Singapore and South Korea. This Nutracene product says it is manufactured in the UK, which to me means that if they put rubbish into it then the UK government might actually prosecute the people who run the business!."

“I am glad I ordered this magnesium supplement product as it has 3 different types of magnesium my body can use. I get less muscle spasms if I regularly take magnesium.”
Michael C
“These are my favourite collagen supplements by a very long way. I wouldn't use collagen on its own and I wouldn't want to use bovine collagen. This supplement contains a range of minerals/vitamins as well as marine collagen. The biotin, hyaluronic acid, vitamin E, C and turmeric are bonuses that together with the marine source of the collagen make this a great product.”
G. Davies
“This Collagen Complex is a great all-in-one supplement for boosting your skin, hair, and nails. Packed with collagen, biotin, vitamin C, hyaluronic acid, and vitamin E, it gives you a well-rounded beauty boost from the inside out.”

These have been my best find this year!I’ve been suffering from stomach pain for the past couple of years and despite tests from the doctors, all my results come back normal so I’ve been at a loss as to how to help myself.When I saw these I thought I’d try them as I don’t like probiotic drinks.I’m not a person that has patience with supplements as they’re more a long term prevention rather than a quick fix…. But i can honestly say, within a week of taking these probiotics, my stomach felt better and now 3 weeks in, I haven’t had a stomach pain!The tablets are quite large and if you have difficulty swallowing pills, these may not be for you, due to their size.I am overjoyed and of course will continue buying these for the foreseeable future.They are a little pricey and if you take two a day, will only last a month but for me, they’re proving to be so beneficial that they’re worth every penny!
Good - but not necessarily the best value option available.
I have tried quite a few probiotics and it has to be said that there is an element of "trial and error" involved in finding the best ones for you.A particular formulation that works wonderfully for one person may not work as effectively for someone else.The key starting point for everyone should be to make sure that you select a product from a reputable source with good quality and provenance credentials - On that score, this product from NUTRACENE ticks the right boxes.This particular product requires you to take two capsules per day. At two tablets a day this pack equates to a 30 day supply.At the current price of £32.99 for 60 capsules these work out at around £1.10 per day, which is on the costly side when compared with other similar quality probiotics on the market. I have tried a number of probiotic supplements that come in around the 60p per day mark, so I would consider that a reasonable benchmark for good quality probiotics.Ultimately, the most important factor is whether the probiotics do the job they are intended to do. These have worked pretty well for me. I certainly haven't had any adverse reaction (unsettled stomach, etc) and my system has been reasonably regular.However, the high daily cost would put me off buying this product in future.I hope you find these comments helpful.
Excellent supplement.Works well for me.I was taking another Tumeric supplement but wasn't finding it effective so decided to try these.Noticed a difference with pain relief quite rapidly.This also has the blend that I find really effective, tumeric and boswellia.I have started by taking just one capsule and that works really well.No side effects or upset at all.Would recommend and repurchase.
