Thank you for the query.
Vitamin B12 is needed for two major functions - to maintain the nerve integrity and to produce red blood cells. Deficiency of vitamin B12 may lead to neuropathy (tingling and numbness) and megaloblastic anemia (anemia where the size of red blood cell is more). Deficiency of vitamin B12 can be treated orally (Mehtylcobalamine 500 my tablets) or with vitamin B12 injections. Non vegetarian food are rich in vitamin B12.
Vitamin D is needed to assist in the absorption of calcium. Vitamin D3 can be treated with injection or tablets (a course is prescribed). Combination of vitamin D and calcium tablets are available. Vitamin D3 is needed to maintain bone integrity. A level be low 20 is deficient and between 20-30 is considered insufficient. Symptoms of vitamin D3 deficiency are generalised - fatigue, weakness and aches/pain. Exposure to good quality sunlight is needed to produce adequate Vitamin D. To know the exact dosage and course of these medications please contact your physician/or any other physician in this forum

A deficiency of vitamin B12 can lead to anemia. A mild deficiency may cause no symptoms. But if untreated, it may progress and cause symptoms which can weekness, tiredness, or lightheadedness
Heart palpitations and shortness of breath.
If you have pernicious anemia or a problem with its absorption, you'll need to replace vitamin B12 by injection initially and�then continued injections, high doses of an oral replacement, or nasal therapy for life.
If the issue is that you don't eat animal products, you can change your diet to include vitamin B12-fortified grains, a supplement or B12 injections, or a high-dose oral vitamin B12 if you are deficient.
VITAMIN D3 DEFICIENCY Symptoms of bone pain and muscle weakness can mean you have a vitamin D deficiency. However, for many people, the symptoms are subtle. Yet, even without symptoms, too little vitamin D can pose health risks. Low blood levels of the vitamin have been associated with the following:
1.Increased risk of death of cardio vascular disease. 2.Cognitive impairment in older adults.
