600 mg of ubiquinol, the reduced and pre-converted form, with vitamin E and omega-3 in the softgel. The dose tier used in fertility and high-dose mitochondrial protocols, where standard 100 mg products would mean swallowing six capsules a day.
The plain-vanilla reference point: 100 mg of standard CoQ10 (ubiquinone) in an oil-based softgel, which is the form most of the older clinical literature actually used. A 150-count bottle at the dose most general-wellness studies tested, with no extra actives to complicate what you are testing.
Combines 1280 mg of omega-3s with 100 mg of CoQ10 in one lemon-flavored softgel. Worth considering only if you were already going to take both, since you are paying for the omega-3 as well. CoQ10 is fat-soluble, so pairing it with an oil base is consistent with how absorption studies dose it.
200 mg per capsule in a capsule rather than a softgel, which matters if you avoid gelatin or prefer to open a capsule. A reasonable step up from the 100 mg baseline without jumping to the high-dose tier.
300 mg per softgel, 100 softgels per bottle, from a warehouse-brand line. The practical pick when a protocol calls for 300 mg or more daily and per-milligram cost, not formulation extras, is the deciding factor.
400 mg of CoQ10 bundled with PQQ and a plant-oil omega blend. Relevant if you specifically want the CoQ10-plus-PQQ mitochondrial stack in a single softgel; skip it if you would rather dose the two separately and know exactly what each one is doing.
