Taking high doses of Vitamin C (ascorbic acid) alongside Oestrogel can increase the levels of oestrogen in your bloodstream. This might increase the risk of oestrogen-related side effects, such as breast tenderness, bloating, or nausea. Conversely, if you suddenly stop taking Vitamin C after your body has adjusted to the combination, your oestrogen levels could drop, potentially causing a return of menopause symptoms.

Why this happens
Both Vitamin C and oestrogen (estradiol) compete for the same 'breakdown' process in the body (specifically a process called sulfation). Because the Vitamin C keeps the breakdown enzymes busy, less oestrogen is cleared from your system, leading to higher levels in the blood.
What you should do
You do not need to avoid Vitamin C, but you should avoid taking very high doses (over 1,000mg per day) of Vitamin C supplements. If you are already taking a Vitamin C supplement, try to be consistent with your daily dose rather than starting and stopping it abruptly. If you notice increased breast pain or other side effects, speak to your doctor.

Behandlung und Medikamente
Can I take Clarithromycin and Rosuvastatin together?
Taking these two medicines together can significantly increase the amount of rosuvastatin in your blood. This increases the risk of serious muscle damage (rhabdomyolysis), which can lead to kidney problems. Symptoms to watch for include unexplained muscle pain, tenderness, or weakness, especially if you also feel generally unwell or have a fever.
