Greens supplements are concentrated blends of vegetables, grasses, algae and other plant-based ingredients, commonly available as powders, capsules or daily packs.

A greens powder is a powdered supplement containing concentrated plant ingredients such as spinach, kale, wheatgrass, barley grass, spirulina or chlorella.

Super greens generally refers to multi-ingredient greens supplements combining several nutrient-rich plant foods, grasses, algae and sometimes additional vitamins, minerals or botanical ingredients.

Their nutritional value depends on the individual formula. Greens supplements can provide a convenient source of plant-based ingredients and selected nutrients, but they should complement rather than replace a balanced diet.

No. Greens powders shouldn't replace whole vegetables and fruit. Whole foods provide fibre, nutrients and dietary variety that cannot necessarily be replicated by a powdered supplement.

Greens powders can generally be taken at any convenient time of day, although you should follow the directions provided with the individual product.

Many greens products are designed for daily use, but recommended serving sizes and ingredients differ between formulas, so always follow the product directions.

Common ingredients include spirulina, chlorella, wheatgrass, barley grass, spinach and kale, alongside fruits, vegetables, botanical extracts and, depending on the formula, added vitamins and minerals.

Greens powders can be useful for people wanting a convenient way to add a broader range of plant-based ingredients to their diet, but they aren't a substitute for eating a varied, balanced diet.
