The greens category is a powder monoculture. AG1 and its hundred imitators all assume you want to drink your greens — and every comparison article just ranks powders against powders. Nobody addresses the actual decision many buyers face: powder or capsules? They're genuinely different products with different winners depending on who you are. Here's the honest breakdown.
The Case for Powder: Dose
Powder wins on one axis, and it's a big one: quantity per serving. A typical greens powder delivers 8–12g of ingredients per scoop. Capsules physically can't match that — a large capsule holds roughly 0.5–0.8g, so even a 3-capsule serving delivers 2–3g.
If your goal is maximum grams of greens per day and you don't mind the ritual, powder is the efficient format. Ours is BioGreenz — 35 superfoods, 300g, organic, and honest about what greens powders can and can't do (we wrote a whole evidence guide vs AG1 on that).
The Case for Capsules: Everything Else
1. Taste — the real reason people quit. Most greens powders taste like sweetened lawn. The industry's workaround is flavouring systems and sweeteners, which is why "greens powder without sweeteners" is such a common search. Capsules delete the problem entirely — and with it, the need for any sweetener, flavouring or masking agent at all.
2. Consistency. A supplement only works if you take it. Capsules travel in a pocket, need no shaker, no water bottle, no washing up, no desk ritual. For commuters, travellers and anyone who's abandoned a half-used powder tub before — that's most of us — the boring format is the effective one.
3. Precision and cleanliness. No scoop variability, no clumping, no half-dissolved sludge at the bottom of the shaker.
The Honest Maths
Don't buy capsules expecting a powder-sized dose — and don't buy powder expecting to still be taking it in March. The real comparison is:
- Powder: ~10g/serving × the servings you actually take before quitting
- Capsules: ~2–3g/serving × every single day, indefinitely
For a large share of real users, the capsule's compliance advantage outweighs the powder's dose advantage. The best format is the one still in use in six months.
Who Should Choose Which
Choose powder (BioGreenz) if: you already make a daily smoothie or shake, you want maximum grams, you'll genuinely sustain the habit, or you're using it partly as a meal-shake base.
Choose capsules (SuperBio) if: you hate the taste of greens drinks, you travel or commute, you've quit powders before, you want zero sweeteners by design, or you're building a simple capsule routine alongside your other supplements.
SuperBio is our capsule format: 35+ organic superfoods in food form with plant enzymes, 100 capsules, vegan and halal approved — the entire greens concept with the shaker bottle removed.
What Neither Format Does
Fair warning either way: greens supplements are a supplement to vegetables, not a replacement. No powder or capsule matches the fibre, water content and satiety of actual plants on your plate. Treat both formats as insurance for imperfect days, not a licence to skip the salad.
FAQs
Are greens capsules as effective as powder?
Per serving, powders deliver 3–5× more raw material. Per month of real-world use, capsules often win because people actually keep taking them. Match the format to your habits, not the marketing.
How many greens capsules equal one scoop of powder?
Roughly 12–15 large capsules would match a 10g scoop — which is why capsules aren't dosed that way. They're a daily micronutrient-and-phytonutrient top-up, not a shake in disguise.
Do greens capsules contain sweeteners?
Good ones contain none — there's nothing to mask. That's a structural advantage of the format, and why capsule greens suit anyone avoiding sucralose and stevia.
Can I take both?
Yes — a common pattern is powder at home in a smoothie, capsules when travelling. Same ingredients philosophy, two delivery methods.
