Take three grams of glycine before bed. It's the cheapest thing that touches sleep.

GlyNAC

Buy glycine and NAC separately. A branded GlyNAC tub holds nothing else.

Vitality · Supplement · members

Glutamate

Cook with MSG. It takes the salt out of the dish and your head's fine.

Metabolism · Supplement · members

Glucosamine Sulfate

Buy crystalline glucosamine sulfate for your knees, or skip glucosamine entirely.

Strength · Supplement · members

Glucoraphanin

Buy the sprout extract with its enzyme, or you're swallowing an inert powder.

Vitality · Supplement · members

Gastrodin

Buy it for headaches. It won't sharpen your thinking or fix your sleep.

Focus · Supplement · members

GLA

Skip primrose and borage oil unless you've got arthritis or diabetic nerve pain.

Defense · Supplement · members

GABA

Stop paying for calm in a gummy. Blood pressure is what GABA actually moves.

Calm · Supplement · members

Folate

Check your B12 before you touch a folate pill.

Vitality · Supplement · members

Fisetin

Skip fisetin. The lifespan number everyone quotes came out of aged mice, not men.

Ferulic Acid

Buy it inside a vitamin C serum, never on its own.

Ferrous Bisglycinate

Test ferritin before you touch iron. No number, no tablet.
