Pure Encapsulations Ascorbic Acid

Heavy training blocks and travel both put real demand on your immune system, and vitamin C needs are easy to underestimate until you're fighting off whatever's going around mid-season. 

Ascorbic Acid delivers pure vitamin C in two formats: 1,000mg capsules for simple daily dosing, or a 1,400mg-per-scoop powder for those who want to adjust their dose without swallowing multiple pills.

Steady Immune Support During Heavy Training – High-dose vitamin C gives your immune system extra backup exactly when travel, training load, and packed schedules make you more susceptible to catching whatever's going around.

Collagen and Tissue Repair Support – Vitamin C is required for collagen synthesis, the connective tissue your joints, tendons, and skin rely on to keep up with repeated training stress.

Antioxidant Defense Against Training-Induced Oxidative Stress – Hard efforts generate free radicals as a natural byproduct of exertion, and vitamin C is one of your body's primary tools for neutralizing them before they add to recovery demands.

Vitamin C is a water-soluble antioxidant your body can't produce or store on its own, so it needs to come from diet or supplementation daily. It supports normal immune cell function, collagen formation, and iron absorption. The capsule delivers 1,000mg of ascorbic acid per serving, while the powder delivers 1,400mg per scoop with no other ingredients added.

How to Use Ascorbic Acid

Capsules: Take 1 capsule, 1 to 4 times daily, with meals, or as directed by a healthcare professional.

Powder: Take 1 scoop daily, with a meal, or as directed by a healthcare professional. Some people prefer starting with a smaller amount, around 1/4 to 1/2 scoop, and adjusting from there.

High-dose vitamin C can increase urinary oxalate, so if you have a history of calcium oxalate kidney stones or kidney disease, talk to your physician before use. Vitamin C also enhances iron absorption, which may not be appropriate if you have hemochromatosis or another iron overload condition, and it can interact with certain ADHD/narcolepsy medications and blood-thinning medications. If you're pregnant, breastfeeding, or taking any medication, consult your physician before use.
