The right supplements don’t replace a strong foundation; they unlock its full potential. For athletes who train with intensity, smart supplementation supports recovery, optimizes output, and protects long-term performance.

At Sur Nutrition, we formulate plant-based supplements with precision. Every ingredient is selected based on published data, third-party testing, and how it performs under real-world training conditions. Whether you need more endurance, better joint mobility, or complete recovery support, we help fill the critical gaps training creates.

Why Should Athletes Take Supplements?

High-intensity exercise taxes every system in the body. Over time, this creates nutrient depletion, slows recovery, and limits adaptation. Supplements help restore balance, supporting performance today and resilience tomorrow.

Sur products are designed to complement a clean diet and high-output training plan. For example, Sur AltRed delivers purified betalains to support oxygen delivery and reduce muscle damage. Sur Joint Support combines FruiteX-B and tart cherry to reduce inflammation and improve joint comfort within seven days. These are just two examples of how data-backed supplementation can give athletes a measurable edge.

Best Supplements for Athletes

The right supplements vary by training goal, but a few core categories apply across endurance, strength, and recovery athletes. Below are five categories where Sur’s plant-based approach stands out.

Beetroot and Betalains

Beetroot is naturally rich in dietary nitrates that support nitric oxide production. This boosts oxygen efficiency, improves blood flow, and can enhance time to fatigue. Sur Organic Beetroot delivers this support in capsule form without the sugar or bloat of juices or powders.

Sur AltRed takes things further by isolating betalains. These antioxidant compounds stabilize nitric oxide and reduce oxidative stress. A 2018 study in the European Journal of Applied Physiology found that betalain supplementation improved running economy and enhanced performance in trained athletes.

Calcium (FruiteX-B)

Calcium plays a foundational role in bone density and muscle contraction. Sur Joint Support uses FruiteX-B, a patented calcium fructoborate shown in clinical studies to reduce joint discomfort in as little as 7 days. It also includes tart cherry extract, which supports strength recovery and natural inflammation control.

This makes it a smart addition for multi-sport athletes, runners, or anyone training at high volume.

Iron

Iron is essential for oxygen transport and energy metabolism. Low iron levels can impair VO₂ max, increase fatigue, and raise resting heart rate. Sur’s Organic Meal Shake includes plant-based iron as part of its whole-food micronutrient profile, supporting daily recovery and endurance.

B Vitamins

B-complex vitamins help the body convert food into energy and support nervous system function. A deficiency can impair aerobic and anaerobic output. Sur’s Organic Meal Shake and fiber-rich plant ingredients like NatureKnit™ offer natural sources of essential B vitamins-including B1, B2, B3, B5, B6, and B9-within a gut-optimized formula that supports digestion and absorption.

Protein

Protein drives muscle repair and recovery. For athletes engaged in regular resistance training or double sessions, adequate protein intake is non-negotiable. Sur’s Organic Meal Shake offers 23 grams of complete plant-based protein, sourced from Puris peas and blended for full amino acid coverage. It digests easily and includes NatureKnit™ for gut support and absorption.
