ENERGYbits: the one-ingredient algae tablets I keep in my bag
I like a supplement that doesn’t come with a long ingredients list. If I can chew it, take it with water, or tip it into a smoothie, even better.
ENERGYbits was founded by Catharine Arnston, who set out to make nutrient-rich algae easy and approachable – just one ingredient, in a simple tablet.[1][2]
Here’s my guide to the two ENERGYbits tablets I recommend: spirulina for the day, and chlorella when I want something a little different.

Why I trust ENERGYbits

Both the spirulina and the chlorella I recommend are vegan, gluten-free and made without fillers or added sugar. You can chew them, swallow them with water, or blend them into a smoothie.[2]

My ENERGYbits favourites
ENERGYbits spirulina: my daytime tablets

These tablets are organically grown spirulina algae, naturally rich in protein, vitamins and minerals. Each serving provides vitamin B12, which helps reduce tiredness and fatigue, iron for normal immune function, and 5g of protein to support muscle growth and maintenance.[2]
You’ll also find naturally occurring thiamine, riboflavin, niacin, magnesium, chlorophyll and carotenoids. They’re vegan, gluten-free, caffeine-free and made without fillers or added sugar. I like them in the morning, mid-day or before a workout.[2]
“I love how they give me a clean, natural boost of energy and nourishment without any crash. They’re such a simple, powerful way to fuel my body with pure goodness and feel vibrant, focused, and strong throughout the day.” - Georgie x
RECOVERYbits chlorella: a simple evening option

RECOVERYbits are made from 100% chlorella algae. Each serving offers naturally occurring protein, vitamins and minerals, including iron and vitamin B12, which contribute to the reduction of tiredness and fatigue. Chlorella is also a natural source of vitamin A for normal vision and skin, and vitamin K for normal bones.[2]
A cracked-cell-wall process is used to support easy digestion. They’re vegan and gluten-free, with no fillers or added sugar, and many people enjoy them in the evening. They pair naturally with the spirulina tablets if you like having both in the house.[2]
“They’re such an easy, natural way to nourish and protect my wellbeing.” - Georgie x

How I take them
💖 Keep it simple. Chew, swallow with water, or blend into a smoothie.[2]
💖 Spirulina in the day. Morning, mid-day or before a workout.[2]
💖 Chlorella when it suits you. Many people enjoy RECOVERYbits in the evening.[2]
💖 Check first. Speak to your GP or pharmacist if you take medication, are pregnant or breastfeeding.[2]
💖 Food first. Supplements aren’t a substitute for a varied, balanced diet.
Why one-ingredient tablets appeal to me
I don’t want a cupboard full of complicated blends. A tablet that’s just algae, that I can take without thinking too hard, is the kind of habit that actually lasts.
That’s the idea Catharine was after when she started ENERGYbits, and it’s why these two have earned a place in my bag.[1]
