CoQ10Shilajit
Half-Life33-36 hours6-10 hours (fulvic acid components)
Typical DosageStandard: 100-300 mg daily with a fatty meal. Ubiquinol form is better absorbed than ubiquinone, especially in older adults. For mitochondrial support: 200-400 mg daily. Statin users may need supplementation as statins deplete CoQ10.Standard: 250-500 mg purified resin daily. PrimaVie is the most studied branded extract. Take in the morning with warm water or milk. Resin form preferred over powder for purity. Effects build over 2-4 weeks. Always buy from reputable sources — contamination with heavy metals is common in cheap products.
AdministrationOral (softgels, capsules). Ubiquinol form preferred for absorption. Take with fat-containing food.Oral (purified resin, capsules). Dissolve resin in warm water. Take in the morning.

Mechanism of Action

CoQ10

CoQ10 (ubiquinone/ubiquinol) shuttles electrons between Complex I (NADH dehydrogenase) and Complex II (succinate dehydrogenase) and Complex III (cytochrome bc1 complex) of the mitochondrial electron transport chain. This is the fundamental process of oxidative phosphorylation—electrons flow through the chain to Complex IV, driving proton pumping and ATP synthesis via Complex V (ATP synthase). Without adequate CoQ10, the chain bottlenecks at the CoQ pool and energy production drops, particularly in high-metabolic tissues like neurons. As a lipid-soluble antioxidant, CoQ10 (in its reduced ubiquinol form) protects mitochondrial membranes from lipid peroxidation by terminating free radical chain reactions. It also regenerates vitamin E (tocopherol) from its radical form, amplifying antioxidant capacity. Brain CoQ10 levels decline with age.

Shilajit

Fulvic acid is the primary bioactive, acting as an electron shuttle that donates and accepts electrons — enhancing mitochondrial electron transport chain efficiency by facilitating electron transfer at Complex I and II, similar to CoQ10 but through a different (non-enzymatic) mechanism. DBPs (dibenzo-alpha-pyrones) protect CoQ10 from oxidation by scavenging radicals, extending its functional life in the reduced ubiquinol form. The combination increases ATP production in mitochondria. Fulvic acid also chelates minerals (iron, zinc, magnesium) via carboxyl and phenolic groups, forming soluble complexes that transport across cell membranes via divalent metal transporter 1 (DMT1) and other channels, improving bioavailability. It has direct antioxidant effects (scavenging ROS) and anti-inflammatory effects through inhibition of complement C3 activation and NF-kB.

Risks & Safety

CoQ10

Common

Mild gastrointestinal discomfort, nausea, diarrhea.

Serious

May reduce the effectiveness of blood thinners (warfarin).

Rare

Insomnia, rash, dizziness.

Shilajit

Common

Mild GI discomfort, metallic taste.

Serious

Heavy metal contamination in unprocessed/cheap products (lead, arsenic, mercury). May increase iron absorption — caution with hemochromatosis. May lower blood pressure.

Rare

Allergic reaction, gout flare (increases uric acid in some people).
