Premium sodium bicarbonate supplementation with the Big-name-brand-equivalent alginate hydrogel system — at a fraction of the price.
Larger corporations pioneered the alginate hydrogel delivery system. We've built the same formulation — at a price every athlete can afford.
Choose the format that works for you — whether you're heading to a race or want something portable for training.
Prices exclude shipping and tax. International shipping available. Discount codes applied at checkout.
A young brand with a clear mission: make elite-level sodium bicarbonate supplementation accessible to every athlete — not just those who can afford bigger brands.
MyCarb was built on a simple observation: the science behind sodium bicarbonate supplementation is undeniable, but the leading delivery system — Bigger companies alginate hydrogel — was priced out of reach for most athletes.
We're a young, lean operation. Products are currently packaged in-house and will scale after takeoff. That keeps our costs low and our prices fair.
Our signed athlete Harrison Jamison (400m: 48.77, 100m: 11.24, 200m: 22.17) represents exactly who MyCarb is for — serious athletes chasing serious times, without a professional-team budget.
Two-sachet system. No shortcuts, no fillers. Just the same alginate-based delivery that makes the bigger company's product work — at a fair price.
We're raising initial investment through Kickstarter and GoFundMe to get production off the ground. Every backer helps us scale from in-house packaging to a proper production line.
Note: All product renders are AI-generated due to budget constraints — we're 16 and building this from the ground up. The renders represent our exact desired design and product vision.
Sodium bicarbonate is one of the most studied ergogenic aids in sports science. Here's what the evidence says — and why delivery method matters.
| Parameter | Recommendation | Notes |
|---|---|---|
| Dose | 0.3g per kg body mass | 0.2–0.4g/kg range; 0.3g is most evidence-backed |
| Timing | 90–240 min pre-exercise | Individual variance; test in training first |
| Format | Alginate hydrogel system | Significantly lower GI distress vs capsules |
| Consumption | Swallow whole — do NOT chew | Chewing breaks the protective gel matrix |
| Best for | High-intensity efforts >1 min | 400m–1500m, cycling TTs, rowing, team sports |
| Hydration | Normal pre-competition hydration | Elevated thirst is normal following SB ingestion |

Individual tolerance varies — start low and see how your body responds. Not a substitute for professional advice.
Take the pre-event dose 90–240 minutes before your event. Individual tolerance varies — start low and see how your body responds, and always test your full race-day plan in training first. This is a reference plan, not medical advice; check with a sports nutritionist if you're unsure.
Enter three recent race times and MyCarb projects your six-month trajectory two ways: standard training alone, and standard training paired with sodium bicarbonate supplementation. Built on training-progression science, not promises.
Provide your details and three recent race results for a single event. Times are auto-detected in any common format — 48.31, 1:53.22, or 1:24:18.
Explore illustrative six-month projections across every event MyCarb models. Select any combination of events to compare on one chart, by percentage or absolute improvement.
MyCarb's predictor combines your own performance trend with general sports-science assumptions about training progression and supplementation response. It is a planning tool, not a promise.
Your three most recent race times establish a personal trend line. A consistent, steady improvement produces a more confident baseline than results that swing up and down — the model treats erratic results more cautiously.
Improvement potential differs by event. Short, largely anaerobic efforts have less room for six-month gains, while middle-distance and endurance events — where pacing, buffering capacity and aerobic economy matter more — are modelled with proportionally greater, but still conservative, headroom.
Gains are never modelled as a straight line. Both projections follow a saturating curve: faster early progress, with each additional month contributing a little less than the one before, matching how real training adaptations behave.
The supplemented line adds a modest, event-weighted buffering benefit on top of the training-only curve. Individual responses to sodium bicarbonate vary with dose, timing, gut tolerance and event demands — the model intentionally stays on the cautious side of published ranges.
