Customers praised these capsules for boosting energy levels, faster muscle recovery, and improved well-being. Many noted benefits for respiratory health, with one saying it "protects your respiratory system from viruses." Shoppers appreciated the quality, convenient packaging, and easy capsule format. One concern was the PP plastic packaging lacking UK recycling.
Since February 2026, when I started taking Spirulina capsules, the muscle recovery is faster, a boost of daily energy and an increase in good mood every day. When time to reload, thinking about the subscription.
I have been taking these for a few weeks now. Seem to have improved how I feel after strength training, no aches and tiredness seems to ge much kess
Hi there! We're so glad to hear that the Spirulina capsules are helping you feel better after your workouts. Thanks for sharing your experience!

Really good product, this is my third time ordering it. Service is fantastic too, convenient packaging for initial purchase (buying the tin) and subsequent refill packs
Excellent product , service and communication
The PP (polypropylene) pot packaging is a no-no. We still don’t have recycling plants in the U.K. for this kind of plastic.
Thank you for your support and feedback, we have been working tireless over the past 2 two years to make our entire range plastic free, we're not quite there yet in regards to the entire range, but our pure organic spirulina is now plastic free!
Kind wishes,
Amazing quality, you can smell the freshness and product, great price point, thank you
Great product, is use it everyday and notice the difference. Speedy delivery.
Good quality products, excellent communication and professional service. A very happy customer, thanks!
Easy Simple ordering
So much easier to take a capsule then mixing in powder form. Wish I known about this years ago
Great experience
I took Spirulina as directed for 3 weeks to give an honest review. I have more energy. I suffered from digestive problems, particularly acid reflux. Not anymore after taking Spirulina. This supplement is organic and pure with no fillers. I have never experienced such profound, positive, natural changes.I feel so much better. I will always choose The Natural Health Market's supplements. It's the best you can give your body at reasonable prices.
Personally, I think these capsules have lots of benefits. However, the major changes I have experienced with using this capsule, is that it really protects your respiratory system from viruses and chest infections. i.e. Colds, flu etc. Since I have been taking these capsules, I have never had any of the above symptoms, which is now over a year. Whereas, before I started taking them, even though, I had regular flu jabs, I still had colds and the flu about twice or three times in a year. So I strongly recommend the above capsules to anyone who wants to purchase them. I always stock mine up when they are about to finish, because it’s one health herbal remedy that I cannot go without using it twice daily. In my eyes it’s totally amazing and brilliant.
Since I have been taking spirulina capsules, I have notice that it has been preventing me from having colds, flu or terrible chest infections. This is very good because it's protecting my respiratory system. There may be other benefits it's helping me with, but this is the one I have notice so far. I really do recommend it to anybody that usually suffers from colds or other respiratory problems to purchase it and use it daily.
Hi! Good product. Surely I will buy one again
How is the spirulina processed? Where does it grow?
Thanks so much for your question!
Our organic spirulina is grown in the clean, mineral-rich waters of Inner Mongolia. The growing environment is carefully managed, and the spirulina is gently spray-dried at low temperatures to help preserve its natural nutrients.
Once it arrives in the UK, we encapsulate it ourselves at our small facility — so we have complete oversight of the final product. We use no additives or fillers, just 100% pure organic spirulina.
The spirulina is certified organic by the Soil Association here in the UK, and our manufacturing site is SALSA accredited, which ensures high food safety and quality standards. It’s also rigorously tested to meet all the usual requirements for organic certification, including checks for heavy metals, pesticide residues, and other impurities.
The capsules we use are made from HPMC (hydroxypropyl methylcellulose), which is vegan-friendly and plant-derived. And we pack everything plastic-free — using home-compostable or fully recyclable materials wherever we can.
Let us know if you have any more questions — always happy to help!
Are your spirulina tablets dried or heated after harvesting do you use heat or do you air dry to keep the enzymes? Because if you use heat then you kill all the enzymes?
Thanks so much for your thoughtful question — it’s a really important one, and we’re glad you asked.
Our spirulina is spray dried using a carefully controlled process designed to minimise nutrient loss while ensuring the product is safe and stable for consumption. The drying process involves a brief exposure to high temperatures (~180°C for less than 5 seconds), followed by a slightly longer phase at 70–75°C for a few more seconds. This very short exposure helps to preserve the nutritional profile of the spirulina as much as possible.
We’re acutely aware of the impact heat can have on enzymes and sensitive nutrients, which is why this method — spray drying — is widely regarded as one of the most effective and gentle techniques for preserving nutrient density in spirulina. While some enzyme activity may be reduced by heat, the vast majority of spirulina’s benefits come from its vitamins, minerals, protein content, and antioxidant compounds, which are much more stable and remain largely intact through this process.
In our view — and based on both research and long-standing global practices — this is an acceptable and responsible method for drying spirulina, balancing safety, shelf stability, and nutrient retention.
We hope this helps, and thank you for your great question!
Warmest wishes,

Where is your spirulina sourced?
Thanks so much for your question! Our regular organic spirulina is sourced from Inner Mongolia, China, where it’s grown in clean, carefully controlled conditions. We also offer a Hawaiian spirulina option for those looking for a different origin.
Both are high-quality, nutrient-dense, and carefully selected to meet our standards — it just depends on your personal preference.
If you have any other questions or need help choosing between the two, we’re always happy to help!
