A 2018 study in humans reported that a supplement containing a combination of magnesium malate and several vitamins caused few digestive side effects. Magnesium citrate

Calcium ascorbate: Calcium ascorbate generally provides 90-110 mg of calcium (890-910 mg of ascorbic acid) per 1,000 mg of calcium ascorbate. Calcium in this form appears to be reasonably well absorbed. The recommended dietary calcium intake for adults is 1,000 to 1,200 mg/day. Total calcium intake should not exceed the UL, which is 2,500 mg/day for adults aged 19-50 years and 2,000 mg/day for adults older than 50 years (see Calcium). Food processing is any method used to turn fresh foods into food products. The procedures used to do this can remove the portions of the plants that often have the highest magnesium content. For example, the process involved in refined grains removes >80% of the magnesium and refining sugar removes all of the Magnesium. The cooking and boiling of produce results in a significant decline of the food's Magnesium content. Reduced Magnesium levels in soil Smoking causes magnesium deficiency due to decreased supply from the diet (lesser appetite) and reduced absorption caused by disturbances in the digestive system functions, as shown in this study on levels of serum iron and magnesium in Sudanese cigarette smokers.

Liposomal Vitamin B

Magnesium Ascorbate is a buffered, non-acidic form of vitamin C (pH of 7.0), which is generally gentler to the stomach when taken away from food than ascorbic acid. Magnesium oxide is also present in some dietary supplements. However, the body does not absorb this form of magnesium well, according to a 2017 analysis. Magnesium taurate The use of herbicides and pesticides also kill off worms and bacteria in the soil. The bacteria in the soil plays an important role in enabling plants to absorb essential minerals. Worms concentrate minerals in their castings in a form that is easy for plants to absorb. All of which is detailed in the research “ The role of soil microorganisms in plant mineral nutrition”.

This is another good form of ascorbate supplementation but it does come with a potential health hazard since it is relatively easy to overdose on potassium which can cause fatal cardiac arrhythmias. Potassium should never be taken on a regular basis unless advised or prescribed by a healthcare practitioner. Other mineral ascorbates Uysal N, et al. (2019). Timeline (bioavailability) of magnesium compounds in hours: Which magnesium compound works best?Nelson E.W., Streiff R.R., Cerda J.J. Comparative bioavailability of folate and vitamin C from a synthetic and a natural source. Am J Clin Nutr. 1975; 28: 1014–1019. Bioavailability refers to how easily a substance is absorbed by the body and refers to the proportion of the administered substance capable of being absorbed along with that available for cellular uptake, use or storage. In short, the amount of magnesium that your tissues can use readily is based on how soluble the magnesium product is and the amount of elemental magnesium that is released. Another factor that affects the absorption of magnesium is the existing magnesium levels of the individual, as magnesium will be less rapidly absorbed if body levels are already adequate and excreted through the urine or stools if given in excess. For example, levels of vitamin C in plasma rapidly fall to half their original concentration during an infection, to levels indicative of a suboptimal status with a risk of deficiency (i.e., ≤50 μmol/L).
