AG1 (Athletic Greens) Review — Is It Worth It?

AG1 is the most talked-about supplement of the last three years, and it genuinely divides opinion. It's expensive, well-formulated, and heavily marketed. The question isn't whether it's a good product — it is — but whether it justifies a price roughly four to eight times higher than its category competitors.

What Is It?

AG1 (formerly Athletic Greens) is a comprehensive daily greens and wellness supplement providing 75 vitamins, minerals, and whole food ingredients per 12g serving. It's sold primarily on a subscription model, positioning itself as a daily nutritional foundation rather than a simple greens supplement.

Ingredients & Nutrition

Per 12g serving: a proprietary blend totalling approximately 7.2g of greens, adaptogens, and functional ingredients, plus individual vitamins and minerals at or near 100% of daily recommended values. At 50 calories per serving, it's one of the few greens powders with a meaningful caloric contribution.

Standout ingredients include spirulina, chlorella, ashwagandha (KSM-66), rhodiola rosea, digestive enzymes, and probiotics. The vitamin D3, B12, and zinc inclusions are at therapeutic levels. The formula is NSF Certified for Sport — significant for tested athletes.

The proprietary blend means individual ingredient doses are not disclosed, which is a legitimate transparency concern for a product at this price.

Taste & Mixability

AG1 has invested heavily in making greens powder palatable, and it shows. The flavour is earthy but with a mild sweetness from stevia — tolerable and arguably pleasant once familiar. It mixes well in water with a shaker, producing a slightly frothy green drink without excessive residue.

Effectiveness

AG1's broad ingredient matrix makes specific efficacy claims difficult to evaluate — the formula covers so many bases that isolating contribution per ingredient is impossible. What the research on the individual components suggests: vitamin D3, magnesium, and B vitamins at these doses will benefit deficient individuals. The KSM-66 ashwagandha and rhodiola dosages are meaningful. The probiotics provide gut health support.

For a well-nourished individual eating a varied diet, AG1 is largely nutritional insurance with some functional additions. For anyone with dietary gaps — limited vegetable intake, vegan diet, or high training load — the comprehensive coverage has genuine value.

Value for Money

At £79.99 per month (30 servings on subscription), you're paying approximately £2.67 per serving. That's the highest per-serving cost in this comparison by a significant margin. Huel Daily Greens at £1.00 per serving and Bulk Complete Greens at £0.50 per serving deliver broadly similar micronutrient coverage for 50–80% less.

Verdict

AG1 is a genuinely good product let down by its price. For tested athletes who want an NSF-certified all-in-one daily supplement, the premium is justifiable. For everyone else, the combination of Bulk or MyProtein greens plus a separate quality multivitamin achieves equivalent nutritional outcomes for a fraction of the cost. The marketing is world-class; the value proposition is not.
