Four things that stop you losing a payment
A deferral costs the whole visit, and almost all of them come down to iron, protein or hydration. These are the cheapest ways to keep yourself eligible.
Nature Made Iron 65 mg Tablets
Under $25
Low hematocrit is the most common reason a donation gets turned away, and a deferral costs you the whole visit. This is the cheapest insurance against losing a payment.

Optimum Nutrition Gold Standard Whey
Under $50
Plasma is mostly protein, and low protein is the second most common deferral. A scoop a day is far cheaper than a wasted trip.

Ultima Replenisher Electrolyte Packets
Under $25
Hydration is what decides whether the draw runs fast or you sit there for an hour. Electrolytes work better than plain water for this.

Compression Arm Sleeves
Under $25
Wearing one after the draw is the simplest thing that reduces bruising, which is what makes frequent donors stop.
