🌿 FAQs About Greens Powders in the UK
1. Are UK greens powders safe and regulated?
Yes, most UK-distributed greens powders follow food supplement regulations, but it's always best to choose brands that disclose full ingredient details and avoid unnecessary additives like sucralose or maltodextrin.
2. Can greens powders replace a multivitamin?
Many modern greens powders (like GRNS) contain enough micronutrients, antioxidants, and digestive support to replace a basic multivitamin but always check the label to see what's covered.
