    I wouldn’t buy my mushroom supplements anywhere else, delivery is fast, customer service excellent.

  2. P

    Great website. So easy to find what you want, with clear and very detailed info on the ingredients. Customer service is excellent. I emailed with a query on the efficacy of an ingredient, and had a reply within 2 days. Delivery was very good too.

  3. DT

    I’ve ordered from this company several times and I’ve always received my items without any problems. I’m very happy with both the products and the service.
    With my last order, I had a small issue with the delivery, which was a little disappointing at first. However, once I contacted the company and explained the situation, they were very helpful and made sure the issue was resolved.
    I really appreciate the effort they made to sort everything out. Overall, I’ve always had a positive experience with this company and would happily order from them again. Highly recommended!

  4. A

    Excellent company to deal with. Quality products & quick delivery. Would buy from again & will! Thank you.

    Great source of Omega 3 if you don’t like fish

    I started taking crown supplements at the beginning of this year and the results have been amazing. I was going through a really hard time because I was having a lot of peri-menopause symptoms. I was always angry, sad, and tired. Also, joint pain and stiffness had taken over my life. It was hard to even bend down to pick something up. I would have to slowly lower myself while holding onto nearby furniture to avoid sharp pain. I used to do yoga every day, but I couldn’t do it anymore because my flexibility and range of motion had gotten so bad. I started with collagen, and while it helped my joints a little, the biggest change was in my skin. It looked brighter, more elastic, and the marionette lines got softer. I also added Spirulina and Magnesium L-Threonate. This is the only type of magnesium I’ve found that doesn’t make my stomach upset. I eventually added turmeric to my daily routine. The colour alone showed how good it was: it was rich and bright. The advanced uptake blend made a big difference, and when I ran out for a short time, I realised how much it had been doing in the background. It’s one of those things where being consistent really helps. I found ingredients I had never even heard of before when I contacted crown supplements for advice on menopausal support. Magnesium L-Threonate, Natural Vitamin C, Vitamin D3 + K2, Silica, MSM, Turmeric, Red Clover, Mucuna L-Dopa, and Spirulina are now all part of my daily stack. I can now move freely, stretch easily, and feel more in tune with my body because my mobility has improved. The biggest difference, in my opinion, has been the synergy of these supplements working together.

    Great

  4. MR

    I’ve taken spirulina in tablet form for a few weeks now, and it’s made a difference in my energy and skin. No fishy taste, just quick tablets I can take with water. Much easier than adding powder to everything!

  5. KS

    Spirulina all good. 1 of a few supplements I get from Crown Supplements.

  6. RG

    As with all of Crown Supplementss stuff. Top quality.

  7. AP

    I received wrong amount of supplements and i never received the rest ones what I have bought so far

  8. EP

    Loving these SPIRULINA capsules!
    (I chose capsules over powder or pressed tablets as they are easily absorbed and don’t have that spirulina taste!)
    I’d always used SPIRULINA as a basic nutrient /food supplement during times of low energy , like glandular fever. But my kinesiologist uses it as an ADAPTOGEN. As I am trying to repair my burnt-out adrenals and lower my crazy high cortisol levels, I’ve found taking these SPIRULINA capsules alongside natural Vitamin C (for extra absorption and adrenal support, specifically ORGANIC AMLA and CAMU CAMU, also from Crown Supplements) and ORGANIC REISHI (for calming my ridiculous cortisol stress) and ORGANIC CORDYCEPS (mornings only, for energy and stamina).

    My morning “hit” is 3x SPIRULINA caps, 3x ALMA caps, 3x CAMU CAMU caps (plus general B-complex and low dose magnesium) and a morning beverage of 1tsp REISHI powder, 1 tsp CORDYCEPS, 1 tsp CACAO and 1 tsp MATCHA in slightly cooled boiled water , topped up with hazelnut milk. Tastes really quite good, like a kind of coffee/hot chocolate, without the jitters.

    Hope this helps anyone who is feeling burnt-out. Adrenal fatigue/ burnout is not fun!

  9. CM

    Great quality Spirulina and customer service. I am very pleased with this product and vaious other products I have purchased from Crown Supplements. Many Thanks!

    I feel more energetic and rarely get sick now.

What exactly is Spirulina?

The distinctive blue-green algae ingredient in a measured capsule format.

Spirulina is the familiar commercial name used for dried biomass from photosynthetic cyanobacteria commonly described as blue-green algae. The material is dried and milled into the Pure Spirulina Powder contained inside each capsule.

Customers may search for Spirulina Capsules, blue-green algae capsules, Spirulina Powder capsules, algae supplements or green algae capsules in the UK. These terms centre on the same recognisable ingredient supplied here in capsule form.

The Crown Supplements formula keeps Pure Spirulina Powder at the centre of every capsule instead of burying the ingredient under filler padding, binder padding or production-line extras.

Spirulina

The familiar ingredient name

Spirulina is the direct customer-facing name used for the deep green powder contained inside these capsules.

The ingredient is also commonly described as blue-green algae powder or algae powder.

Blue-Green Algae

The recognised category name

Blue-green algae is the familiar descriptive category widely used for Spirulina products.

The capsule contains the same recognisable Spirulina Powder in a pre-measured, enclosed format.

Loose Spirulina Powder

Powder supplied directly in a pouch

Loose Spirulina Powder requires the powder to be measured separately before use.

Crown Supplements Spirulina Capsules

Pre-measured powder in HPMC shells

Each capsule contains 373mg of Pure Spirulina Powder, giving 746mg in every two-capsule serving.

Understanding the serving

746mg per serving. 1,492mg across the day.

The specification separates the amount inside one capsule, the combined amount in a two-capsule serving and the complete recommended daily amount across two servings.

746mg

The two-capsule serving

Two capsules supply a combined 746mg of Pure Spirulina Powder.

That provides an exact physical ingredient amount of 373mg inside each capsule.

1,492mg

The complete daily amount

The recommended use is two capsules, two times per day.

Four capsules therefore supply a combined daily total of 1,492mg of Pure Spirulina Powder.

Serving numbers made simple

373mg per capsule. Two capsules per serving. Two servings per day.

The ingredient amount, serving size and recommended use work together without an undefined blend or inflated equivalent figure.

Why choose these Spirulina Capsules?

The Spirulina should lead the capsule.

British shoppers choosing Pure Spirulina Capsules are paying for the algae powder. Crown Supplements keeps the formula centred on that ingredient instead of turning the capsule into a production checklist.

01

Pure Spirulina Powder

The named blue-green algae ingredient remains at the centre of the capsule formula.

02

746mg per serving

Every two-capsule serving supplies an exact combined ingredient amount of 746mg.

03

373mg per capsule

The physical Spirulina Powder amount inside each individual capsule is easy to compare.

04

HPMC capsule shell

The Spirulina Powder is enclosed in HPMC hypromellose capsules.

05

Four pouch choices

Choose 90, 180, 270 or 360 capsules according to the supply required.

06

No capsule padding

No fillers, binders or machine flow agents are added by Crown Supplements.

The Crown Supplements formula standard

Built around Spirulina—not manufacturing convenience.

When capsules include filler padding, bulking materials, binders, lubricants, anti-caking agents or machine flow agents, part of the capsule is being built around production instead of the Spirulina customers came to buy.

They may help the machine. They are not the reason the customer buys the capsule.

What filler-heavy capsules add

Filler material occupying capsule space beside the Spirulina Powder
Bulking material making the capsule look fuller without adding more Spirulina
Binding materials included around high-volume production requirements
Lubricants and anti-caking agents included around machinery rather than customer buying intent
Machine flow agents taking space in a formula customers expected to be centred on Spirulina
Why pay for capsule padding when Spirulina is what matters?
