Yes, you can safely take vitamin C and D together, as they complement each other for immune support, bone health, and wound healing, and don't interfere with each other's absorption, but it's best to take D with a meal containing fat and C on an empty stomach or with water for best absorption, and always follow dosage guidelines.
Taking vitamin C and D together is generally safe if you stay within the recommended doses. Vitamin C and D supplements may support your immune health and strengthen your bones. Higher vitamin C or D doses can cause side effects like nausea or diarrhea.
Vitamin C supports your baby's growth and helps your body absorb iron. Pregnant women need 85 mg of vitamin C daily – more than before pregnancy. You'll most likely get enough vitamin C through your diet and a prenatal vitamin; there's no need for extra supplements.
Vitamin A, C, and E
These three “antioxidant” vitamins for acid reflux protect and strengthen the esophageal lining. One study showed that those with higher intake of vitamins A, C, and E had a significantly lower risk of GERD.

The Role of Vitamin D
Furthermore, some research suggests that vitamin D deficiency may be linked to an increased risk and severity of osteoarthritis, a common cause of joint pain. Ensuring adequate vitamin D levels through sunlight exposure, diet, or supplementation can be a crucial step in managing joint discomfort.
Taking too much vitamin C can cause diarrhea, nausea, and stomach cramps. In people with a condition called hemochromatosis, which causes the body to store too much iron, high doses of vitamin C could worsen iron overload and damage body tissues.
Vitamin C has low toxicity and is not believed to cause serious adverse effects at high intakes [8]. The most common complaints are diarrhea, nausea, abdominal cramps, and other gastrointestinal disturbances due to the osmotic effect of unabsorbed vitamin C in the gastrointestinal tract [4,8].
Do not take vitamin C at night before bed, as its stimulating properties can cause excitability and insomnia. Take vitamin C after meals, as this timing allows for better absorption through the stomach and intestines. Taking it before meals may lead to excretion and reduced effectiveness.
Vitamin C supplementation is contraindicated in blood disorders like thalassemia, G6PD deficiency, sickle cell disease, and hemochromatosis. Avoid taking supplements immediately before or following angioplasty.
Good sources of vitamin C
Research shows vitamin C supplementation is associated with shorter time to pregnancy. As for vitamin C's impact on male fertility, The Nutrition and Food Security Research Center found that taking vitamin C with vitamin E improved the number, motility, and sometimes DNA quality of sperm.
Research shows that daily vitamin C supplements may help reduce the severity and duration of the common cold but that they do not prevent it altogether. Daily vitamin D supplements have been found to protect against acute respiratory infections, in particular for patients who are deficient in vitamin D.
This meta-analysis of 20 RCTs demonstrated that vitamin D supplementation significantly alleviates depressive symptoms, with an overall standardized mean difference (SMD) of -0.36 (95% CI: -0.52 to -0.20, p < 0.00001), supporting its role as a viable adjunctive therapy for depression.
Some vitamins that should not be taken together, or have dosage limitations, include vitamin C with vitamin B-12, vitamin A supplement with vitamin A-rich foods, folic acid (vitamin B9) and vitamin B12, and vitamin E with vitamin K.

4.6 Bacterial microbiome affecting lower GI tract dynamics may indirectly trigger GERD. The microbiome may induce reflux by affecting the lower GI tract dynamics, which in turn affects emptying. Lower GI pressure plays an important role in the pathogenesis of GERD.
GERD can put you at increased risk for serious health complications, including esophagitis, or inflammation of your esophagus. It can also increase your risk for a rare disorder called Barrett's esophagus.
With a vitamin C content of 2,300 to 3,150 mg per 100g of pulp, Kakadu plum (Terminalia ferdinandiana; also known as gubinge or billygoat plum) is very likely the fruit with the highest content of vitamin C.
Serious side effects from too much vitamin C are very rare, because the body cannot store the vitamin. However, amounts greater than 2,000 mg/day are not recommended. Doses this high can lead to stomach upset and diarrhea, and, although rarely, kidney stones.
Taking more than 2000 mg daily is possibly unsafe and may cause kidney stones and severe diarrhea. In people who have had a kidney stone, taking amounts greater than 1000 mg daily increases the risk of getting more kidney stones. When applied to the skin: Vitamin C is likely safe for most people.
Studies show that too much vitamin A can contribute to hair loss, as can too much selenium, although more studies are needed to establish the latter relationship. Alopecia areata (AA) occurs when the immune system attacks the hair follicle. Studies have shown a relationship between AA and low vitamin D levels.
Vitamin C might react with the following:
