Why We Don’t Include Calcium in Our Electrolyte Formula

In creating SALZ Hydration, we carefully selected ingredients that offer maximum hydration and support for active lifestyles. One common electrolyte found in other hydration products is calcium, but we intentionally chose to leave it out. Here’s why.
The Importance of Calcium in the Body
Calcium is crucial for several bodily functions:
- Bone Health: Most of our body’s calcium is stored in the bones and teeth, supporting structure and strength.
- Muscle Function: Calcium helps muscles contract and release properly.
- Nerve Function: It plays a role in nerve transmission, allowing for effective communication between cells.
Since calcium is vital, it’s easy to assume that it should be a part of every supplement. However, calcium requirements are often met through diet, and supplementing it—especially through tablets or powders—can introduce unnecessary risks.
The Risk of Calcium Supplementation on Cardiovascular Health
Studies, including a 2017 review in Endocrinology and Metabolism (Seoul) by Ian R. Reid et al., indicate that calcium supplementation may have unexpected effects on cardiovascular health. The study concludes that increased serum calcium levels from supplements can be a risk factor for vascular diseases. When calcium is supplemented, it causes a temporary spike in serum calcium levels. Over time, these repeated spikes have been associated with an increased risk of cardiovascular issues, such as:
- Artery calcification: Excess circulating calcium can lead to calcium deposits in the arteries, which may reduce arterial flexibility and increase heart disease risk.
- Kidney strain: The kidneys work to filter out excess calcium from the bloodstream. Supplementing calcium puts extra pressure on kidney function, especially in those with pre-existing kidney conditions.
For those consuming balanced diets with sufficient calcium, these risks may outweigh the benefits. In cases of bone health concerns or osteoporosis, it’s often best to consult a healthcare professional who can suggest safe, alternative options, such as vitamin D or magnesium, for bone support.
How Diets Naturally Affect Calcium Levels
Most individuals obtain adequate calcium through their diets, especially when they consume a varied, whole-food diet. Here’s how different diets impact calcium intake:
- Whole-Food Diets: Typically include calcium-rich foods like leafy greens, nuts, seeds, and dairy, offering a natural and bioavailable form of calcium.
- Dairy-Free and Vegan Diets: While avoiding dairy, vegans and some vegetarians can rely on leafy greens (like kale and collard greens), almonds, sesame seeds, and calcium-fortified products.
- Keto and Low-Carb Diets: Can still be high in calcium by incorporating low-carb greens, cheeses, and nuts, meeting daily needs without supplementation.
While some diets naturally provide less calcium (such as those avoiding dairy or specific vegetables), many foods are naturally rich in bioavailable calcium, reducing the need for added calcium in supplements.
Foods Naturally High in Bioavailable Calcium
There are many foods with bioavailable calcium that don’t carry the risks associated with supplements:
- Leafy Greens: Kale, collard greens, and broccoli are great sources of calcium with high absorption rates.
- Nuts and Seeds: Almonds, chia seeds, and sesame seeds provide calcium along with healthy fats.
- Dairy Products: Milk, cheese, and yogurt are well-known sources of calcium, especially useful in a non-dairy-restricted diet.
- Calcium-Fortified Foods: Many plant-based milks and juices are fortified with calcium, making them excellent options for those on dairy-free diets.
Who Should Consider Calcium Supplementation?
While most individuals get enough calcium from diet alone, some may need to supplement:
- Postmenopausal Women: At higher risk for osteoporosis and may benefit from monitored calcium intake.
- Strict Vegans: Those without access to fortified products or diverse greens might need additional calcium.
- Individuals with Absorption Issues: People with gastrointestinal conditions may not absorb calcium well from food.
If supplementation is necessary, it’s important to work with a healthcare provider to balance calcium intake with other bone-supporting nutrients, like magnesium and vitamin D.
Why SALZ Hydration Skips the Calcium
Our electrolyte formula is carefully crafted to support active lifestyles, high-intensity training, and hydration without unnecessary risks. We chose not to include calcium in our blend because:
- Dietary Availability: Most people can meet their calcium needs through whole foods.
- Health Risks: The cardiovascular risks linked to calcium supplementation aren’t worth the potential benefits in a hydration supplement.
Instead, we focus on sodium, potassium, and magnesium—minerals crucial for hydration, muscle function, and nerve transmission. Our high-sodium formula is designed specifically for those who sweat a lot in hot climates like Thailand, providing a pure and effective electrolyte balance without unnecessary additives or risks.
By sticking to only essential electrolytes, SALZ Hydration offers a clean, targeted hydration solution that supports performance and recovery, especially in Thailand’s challenging climate.
