Stark Calcium Citrate Powder 270 grams — citrate form of calcium for bones and muscles
Stark Calcium Citrate Powder — calcium in citrate form in powder for daily diet and sports regimen.
Calcium is one of the key minerals involved in the mineralization of bones and teeth, muscle function, and supporting nerve transmission.
Calcium citrate is less dependent on stomach acidity, so it may be a convenient option for regular use, particularly in people with low acidity.
Briefly about the product:
- 1 serving — 3500 mg (1 measuring/teaspoon without a slide).
- Calcium citrate — 3500 mg (of which calcium — 700 mg) per 1 serving.
- Form: powder.
- Packaging: 270 gram polymer jar.
- Nutritional value per 100 g: proteins — 0 g, fats — 0 g, carbohydrates — 0 g.
- Energy value per 100 g: 0 kcal/0 kJ.
- It is recommended to use with the Stark D3-K2-K1 Liquid Extract supplement.
How it works:
- Ionized calcium: After dissolving calcium salt, calcium ions are formed that can be absorbed in the intestines.
- Transcellular pathway: some calcium can be absorbed through intestinal cells with the participation of transport proteins sensitive to vitamin D status.
- Paracellular pathway: with sufficient supply, calcium can be partially absorbed between cells through intercellular contacts.
- Muscle contraction: Calcium is involved in triggering muscle fiber contraction and maintaining normal muscle function.
- Neurotransmission: Calcium is involved in the transmission of signals between nerve cells and neuromuscular synapses.
- Citrate form: may be less dependent on stomach acidity, which is important for the dissolution and subsequent absorption of minerals.
- Synergy with D and magnesium: A combination with vitamin D and magnesium may be appropriate for comprehensive support of calcium metabolism.
The effect of the Stark Calcium Citrate Powder supplement
- Bone tissue: may help maintain bone mineralization when combined with a balanced diet and physical activity.
- Teeth: Helps maintain the structural strength of teeth as a source of calcium.
- Muscles: May help maintain normal muscle function during exercise and an active lifestyle.
- Nervous system: participates in the processes of transmission of nerve impulses.
- Electrolyte balance: may help maintain mineral balance in the diet.
- Performance: can help maintain comfort during regular exercise due to the role of calcium in muscle function.
- Daily diet: may be recommended to increase calcium levels in the diet.
Benefits of the formula
- Calcium citrate: A form of calcium that may be less dependent on reduced stomach acidity.
- Powder form: convenient dosing and the ability to add to water or food.
- Clear portion: 1 serving = 1 measuring/teaspoon without a slide.

Who might be interested?
- Adults who want to increase their calcium intake through their diet.
- For those who train and are looking for mineral support for the musculoskeletal system.
- People with low acidity, when the absorption of some mineral forms may be difficult.
Scientific data
1. Bioavailability of calcium citrate
Source: Sakhaee K. et al. Meta-analysis of calcium bioavailability: a comparison of calcium citrate with calcium carbonate. Am J Ther. 1999. PMID: 11329115.
Briefly: In a meta-analysis, calcium citrate demonstrated higher absorption compared to carbonate (by approximately 22–27%) both in the fasting state and with food.
2. The role of dissolution and acidity in calcium absorption
Source: Shkembi B. et al. Calcium Absorption from Food Products: Food Matrix Effects. Nutrients. 2022;14(1):180. DOI: 10.3390/nu14010180.
Briefly: The review describes that for absorption, calcium must be in ionized form; dissolution of calcium salts occurs in the digestive tract, and different salts may vary depending on environmental conditions and food availability.
3. Calcium combined with vitamin D and bone mineral density
Source: Baeksgaard L. et al. Calcium and vitamin D supplementation increases spinal bone mineral density in healthy, postmenopausal women. Osteoporos Int. 1998. PMID: 9797910.
Briefly: In a randomized, placebo-controlled trial, the combination of calcium and vitamin D was associated with increased bone mineral density compared to placebo.
Composition
Composition per 1 serving (3500 mg): calcium citrate (where calcium is 700 mg) - 3500 mg.
