Supplement

Yohimbine

Take it for erections and bin the fat-burner claim. Never on top of a stimulant.

Xylitol

Chew it for your teeth. Don't sweeten your whole day with it.

Looks · Supplement · members

Whey vs. Casein

Buy the cheaper tub. Daily protein total builds the muscle, the label barely counts.

Strength · Supplement · members

Whey Protein Isolate

Drink whey to hit your protein number. The lifting is what turns it into muscle.

Strength · Supplement · members

Whey Protein Concentrate vs. Isolate

Buy the concentrate. The isolate premium buys less lactose, not more muscle.

Strength · Supplement · members

Wellmune

Run Wellmune through winter or a hard training block, then stop.

Defense · Supplement · members

Vitamin K2 (MK-4 & MK-7)

Don't buy the D3-plus-K2 bundle. Those trials ran in postmenopausal women.

Vitality · Supplement · members

Vitamin K1

Eat the greens, skip the K1 capsule. Your body needs it, your cupboard doesn't.

Vitality · Supplement · members

Vitamin D

Take 2000 IU daily. Never a once-a-year megadose, never 10,000 a day.

Defense · Supplement

Vitamin C

Take it every day or don't bother. Starting once your throat hurts does nothing.

Defense · Supplement

Vitamin B6

Add up the B6 in everything you take. High doses numb your hands and feet.

Vitality · Supplement · members

Vitamin B12

Skip the energy shot. Get tested, and ask for methylmalonic acid, not just B12.
