First time using AltRed? Here is what to expect.
AltRed helps you break through that training plateau, whether you’re increasing your weekly mileage or pushing the pace. Unlike other products that may act as fuel (providing carbs, electrolytes, sugar, etc.), AltRed increases your performance by allowing your aerobic system to function optimally (improves blood flow &
oxygenation, raises lactate threshold, etc.). This allows you to sustain an activity for longer. Most people don’t feel a difference until they reach their limit and are able to keep going. Others recognize how they feel fresher and less sore during recovery.
What is AltRed?

We take a different (better) approach to our beet sports supplement. AltRed is a beetroot extract but with 25% unleashed betalains. Think nitric oxide without the nitrates. The unleashed betalains help your body create its own type of nitric oxide called HbNO. HbNO lasts 10,000 times longer in your body. This allows you to sustain an activity for longer. Anti-inflammatory benefits for recovery. Oh, and there is no sugar (for real!).

What does "unleashed betalains" mean?¬†Betalains are a unique nutrient in beets with sports performance and recovery benefits. However, we like to say that they‚Äôre found in beets, but you can‚Äôt really get them from beets. That‚Äôs where our extraction process comes in. We ‚Äėunleash‚Äô the betalains from the plant matrix making them significantly more absorbable in your body (over 1,000% more bioavailable)!

Betalain-Rich Concentrate Supplementation Improves Exercise Performance and Recovery in Competitive Triathletes (University of California, Davis)

  • The study examined the effects of a betalain-rich concentrate (BRC) on triathlete performance and recovery.
  • 22 triathletes participated in the study, which involved a week of either BRC or placebo supplementation.
  • After the week, participants performed a cycling and running trial.
  • The study found that those who took BRC ran faster in a 10-km trial.
  • Despite running faster, BRC participants didn't experience increased heart rate or perceived exertion.
  • BRC participants also ran faster in a 5-km trial held 24 hours after the 10-km trial.
  • BRC supplementation resulted in less increase in creatine kinase, a muscle damage marker.
  • Participants reported less fatigue increase after 24 hours with BRC.
  • The study concluded that BRC improved performance and recovery in triathletes.

Betalain-Rich Concentrate Supplementation Improves Exercise Performance in Competitive Runners (University of California, Davis)

  • The study aimed to investigate the effects of a betalain-rich concentrate (BRC) on performance and exercise-related muscle damage.
  • The study involved 13 competitive male runners who completed two trials (BRC and control) separated by seven days.
  • Each trial was preceded by six days of supplementation with 100 mg of BRC or a control substance.
  • On the seventh day, exercise trials began 150 minutes after supplementation with 50 mg BRC or control and consisted of 30 minutes of treadmill running followed by a 5-km time trial (TT).
  • During exercise at the same intensity, BRC resulted in a 3% lower heart rate, a 15% lower rate of perceived exertion (RPE), and a 14% lower blood lactate concentration compared to the control.
  • The 5-km TT duration was faster in 10 of the 13 subjects, and RPE was lower with the BRC treatment compared to the control.
  • Despite the improved performance, lactate dehydrogenase, a marker of muscle damage, increased less from baseline to immediately and 30 min after the 5-km TT with the BRC treatment.
  • The study concluded that BRC supplementation improved 5-km performance time in male competitive runners.

Is AltRed vegan?

AltRed ingredients and its capsule are vegan-friendly. It is not derived from and does not contain animal products, and is suitable for vegetarian and vegan diets. 

    Does AltRed contain oxalates?

    Does AltRed contain caffeine or any other stimulants?

    Does AltRed contain nitrates?

    AltRed does not contain dietary nitrates. They are removed during our betalains extraction process. 

    Wait... what? The unleashed betalains in AltRed help your body create its own type of nitric oxide called nitrosylated hemoglobin or NOHb (Also written as HbNO). NOHb lasts 10,000 times longer in your body. This allows you to sustain an activity for longer. You aren't going to feel a rush or tingle. Most people don’t actually notice a difference until they reach their limit and are able to keep going. Others recognize how they feel fresher and less sore during recovery.

    Does AltRed contain sugar?
    AltRed does not contain sugar (for real!). Sugar is removed during our betalains extraction process. Beets on their own have a lot of sugar. The typical beet supplement is 30% sugar! AltRed gives you all the benefits of beets without all that sugar or gastro distress. ūüöĹ

    Beeturia is the passing of red or pink urine after eating beetroots, beetroot extract, or beetroot pigments. The color is caused by the excretion of betalain pigments.
