Ultra-clean: How we define clean.

We define clean as containing no silicon dioxide, magnesium stearate, additives, GMOs, harmful chemicals, fillers, flow agents, dyes, colors, artificial sweeteners, artificial flavors, preservatives, or banned substances. We go above and beyond industry standards, omitting all of the added junk, fillers and artificial ingredients found in almost all other supplements on the market that bulk up volume and improve flavor but do nothing to help performance and are generally bad for your health.Our Ingredients

How does PurePump taste?

Taste warning: PurePump is bitter. Intentionally. There's no sucralose, no artificial flavoring, nothing hiding the raw ingredients. If you want a delicious fruity beverage, this isn't it. If you want 15 active ingredients with nothing to hide behind, welcome.

How should I mix PurePump?

How to mix: Less water, shaker bottle, think shot not drink. Mix with juice or lemonade to cut the bitterness. Or just embrace it — there's nothing in there except what's working for you.

15-30 minutes before training. If you get the beta-alanine tingles, you're ready.How much:Full dose (2 scoops / 7.6g): 200mg caffeine, all 15 ingredients at full strength. For most athletes, most of the time.Half dose (1 scoop / 3.8g): 100mg caffeine. For evening training, caffeine-sensitive athletes, or your first week while you assess tolerance.

Do Vitamins | Natural Pre-Workout Supplements

It's what's inside that counts.

Most pre workouts are 12-15g per serving — half of that is artificial sweeteners, dyes, and fillers. PurePump fits 15 branded, third-party tested ingredients into 7.6g because there's nothing else in the container. Every gram is doing something.

CarnoSyn® beta-alanine. Kyowa Hakko L-citrulline. CreaPure® creatine. AjiPure® amino acids. Caffeine from green tea. Eight patented ingredient sources you can look up and verify.

The Do Vitamins Difference

"The Best Pre Workout Supplement"

My husband and I both love this product. We are allergic to coffee and this is the only product we've found that does not contain coffee yet still gives us the energy to power through our workouts.
