Over Black Friday, I bought a 333-day supply of spirulina for just over £20. I couldn’t be happier. I’ve just drawn to the end of my previous 2k pill supply, so the Black Friday deal at Amazon has arrived at the perfect time. It’s one of the best supplements, and I thoroughly recommend it to anyone interested in improving their vitamin intake, supporting their immune system and possibly improving digestion.

According to my research, the last time they were cheaper than this was in January 2023, when the price dipped to £19.99 for the New Year. Though a 15 percent discount isn’t the most significant cost reduction, I’m happy to save myself some cash for such an essential supplement in my routine.

Though the Black Friday deal is over, I still consider the product to be an excellent purchase at full price.

I’ve incorporated Sevenhills Wholefoods Organic Spirulina 500mg Tablets (winner of our best spirulina roundup) into my daily routine for the last year. As a vegetarian, I initially wanted spirulina to address nutrient gaps in my primarily plant-based diet. However, the benefits have gone far beyond giving me extra vitamins.

Most notably, I noticed a positive impact on my stomach health. It turns out that spirulina acts as a prebiotic, providing nourishment for the good bacteria in your gut. Studies show that spirulina can boost the number of beneficial bacteria while reducing the harmful ones. These friendly fellas play a crucial role in digestion, absorbing nutrients, and keeping your immune system in tip-top shape.

I’ve found Sevenhills Wholefoods Organic Spirulina Tablets to be a top-notch and cost-effective supplement. Sevenhills ensures the quality of its spirulina, making it a reliable choice for those seeking a natural and organic supplement. These tablets offer a potent 500mg of freshwater-grown, certified organic spirulina. With the flexibility to take up to six pills a day - which I do with breakfast - you can easily customise your daily intake to suit, especially most recommend that you build up to this level over a few weeks.

At full retail price, which is £24.99, the daily dose of six is only 7p. Considering the benefits that I feel, you’ll hear no complaints from me!


  • Certified vegan, organic, and GMO and heavy metal-free
  • Convenient to take
  • Available in bulk


  • The six-tablet dose is a bit of a mouthful at first

More about spirulina

Spirulina, Blue-green algae. Spirulina represents a biomass of cyanobacteria (blue-green algae)

Spirulina, a microscopic, spiral-shaped, blue-green alga thriving in warm, alkaline water, boasts a rich history as a nourishing food source. Civilisations like the Aztecs and Kanem-Bornu tribes have used it. Its vibrant green colour, attributed to chlorophyll, signals its nutrient density, comprising high-quality plant protein, vitamins, minerals, and antioxidants, earning its superfood status.

Consumable as a supplement in tablets or powder, spirulina integrates easily into diets through smoothies, juices, energy bars, soups, or salads. Beyond its nutritional value, spirulina garners attention for potential health benefits, including immune system support, cholesterol reduction, anti-inflammatory properties, and potential contributions to weight management.

However, while spirulina is generally safe when consumed in recommended amounts, it may induce side effects in some individuals. Consulting a healthcare professional, especially for those with underlying health conditions, is advisable. Furthermore, ensuring the quality and safety of spirulina products by purchasing from reputable sources is crucial for a positive and healthful experience.
