AG1
AG1 is middling — some recognized ingredients, but dosing or disclosure holds it back.
Ingredients by dose
What's actually in it, ranked by how well it's dosed against research thresholds.
What it does
Evidenced benefit intensity, derived from dosed ingredients — not label claims.
The receipt
Every point of this grade, traced to the ingredient, its dose, and the evidence.
Vitamin A (Retinol / Beta-Carotene) at 555 mcg — underdosed
Below the ~700 mcg effective dose, so the labeled benefit is unlikely at this amount.
Vitamin C at 420 mg — effective dose
Meets the ~200 mg effective threshold. NIH ODS/meta-analyses: 200-1000 mg/day saturates plasma and modestly shortens common-cold duration; antioxidant. UL 2000 mg.
Vitamin E at 83 mg — effective dose
Meets the ~15 mg effective threshold. NIH ODS: 15 mg meets requirement; antioxidant. High-dose supplementation shows no clear benefit and may carry risk. UL 1000 mg.
Vitamin B6 (P5P) at 3 mg — effective dose
Meets the ~1.3 mg effective threshold. NIH ODS: RDA 1.3-1.7 mg/day supports amino-acid and neurotransmitter metabolism; benefit beyond requirement only if deficient. The old US UL of 100 mg is outdated — EFSA lowered the upper limit to 12 mg/day (2023) and multiple regulators (TGA, Medsafe, NPRA) issued 2025-2026 alerts after peripheral-neuropathy cases at doses well under 50 mg, occasionally under 12 mg in sensitive people. Keep total B6 from all supplements low and time-limited.
Folate (Methylfolate) at 680 mcg — effective dose
Meets the ~400 mcg effective threshold. NIH ODS: 400-800 mcg DFE/day supports red-blood-cell formation and is essential preconception/pregnancy. UL 1000 mcg (folic acid).
Vitamin B12 at 22 mcg — underdosed
Below the ~500 mcg effective dose, so the labeled benefit is unlikely at this amount.
Calcium at 118 mg — underdosed
Below the ~500 mg effective dose, so the labeled benefit is unlikely at this amount.
Magnesium Glycinate at 26 mg — underdosed
Below the ~200 mg effective dose, so the labeled benefit is unlikely at this amount.
Zinc at 15 mg — effective dose
Meets the ~15 mg effective threshold. Meta-analyses: 15-30 mg/day supports immune function; lozenges may shorten cold duration. UL 40 mg; pair with copper if used long-term.
Selenium at 20 mcg — underdosed
Below the ~55 mcg effective dose, so the labeled benefit is unlikely at this amount.
Spirulina present — dose hidden in a proprietary blend
A recognized ingredient, but the label doesn't disclose its individual dose, so we can't confirm it reaches the effective ~1 g.
Fiber (Inulin / Psyllium) present — dose hidden in a proprietary blend
A recognized ingredient, but the label doesn't disclose its individual dose, so we can't confirm it reaches the effective ~5 g.
CoQ10 (Ubiquinone / Ubiquinol) present — dose hidden in a proprietary blend
A recognized ingredient, but the label doesn't disclose its individual dose, so we can't confirm it reaches the effective ~100 mg.
Vitamin K2 (MK-7) at 7 mcg — underdosed
Below the ~90 mcg effective dose, so the labeled benefit is unlikely at this amount.
Pros & cons
The honest tradeoffs.
- Vitamin C dosed to the effective threshold (420 mg)
- Vitamin E dosed to the effective threshold (83 mg)
- Vitamin B6 (P5P) dosed to the effective threshold (3 mg)
- Folate (Methylfolate) dosed to the effective threshold (680 mcg)
- Zinc dosed to the effective threshold (15 mg)
- Vitamin A (Retinol / Beta-Carotene) appears underdosed (555 mcg) — labeled benefit unlikely
- Vitamin B12 appears underdosed (22 mcg) — labeled benefit unlikely
- Calcium appears underdosed (118 mg) — labeled benefit unlikely
- Magnesium Glycinate appears underdosed (26 mg) — labeled benefit unlikely
- Selenium appears underdosed (20 mcg) — labeled benefit unlikely
- Spirulina's dose is hidden in a proprietary blend — can't confirm it's effective
