I have read conflicting views on whether a vegan diet is healthy and without supplements its not.

Vitamin B12
We need B12 to maintain healthy nerve cells, produce DNA – the body’s genetic material – and it works closely with folic acid to make red blood cells. It also helps iron to work better in the body and is essential for a healthy immune system as well as helping to regulate mood. It really is an important vitamin!Vitamin D
We need vitamin D for healthy bones, teeth, muscles and other essential functions. Known as the sunshine vitamin, it’s made through the action of sunlight on skin. UK levels of vitamin D deficiency are high, particularly among people with darker skin and for everyone during the winter months. In spring and summer, most people in the UK can make enough through daily exposure to sunlight for five to 25 minutes – this short timespan minimises the risks of sunburn and skin cancer. The lighter your skin, the less exposure you require and ‘little and often’ is the best approach for most people.Calcium
A healthy vegan diet, rich in wholegrain foods, pulses, nuts and seeds, will cover your needs for this mineral. The best sources include tofu (made with calcium sulphate), fortified vegan breakfast cereal, plant-based milks fortified with calcium, dried figs, kale, sesame seeds and tahini, tempeh, wholemeal bread, baked beans, butternut squash, nuts (particularly almonds and Brazil nuts), spring greens and watercress. While spinach, chard and beet greens do contain calcium, they also contain a substance called oxalate, which blocks calcium absorption. Calcium is more available from low-oxalate green vegetables such as kale, broccoli and bok choy. The calcium they contain is absorbed about twice as well as the calcium in cow’s milk, plus they contain fibre, folate, iron and antioxidants, which you won’t find in a pint of milk!Iodine
We need iodine for healthy thyroid function and to help regulate how energy is produced and used in our bodies. The dairy industry likes to warn how vegans miss out on iodine by shunning cow’s milk. The truth is that iodine is not naturally found in dairy milk but comes from supplements fed to cattle and iodine-containing disinfectants that are used to clean teats and udders.Omega-3s
Our bodies can’t produce essential omega-3 fats so we need some in our diet. They are a part of our cell membranes and affect cell functions throughout the entire body. They help us produce hormones and control inflammation and may lower the risk of heart disease. One or two teaspoons of flaxseed oil daily, or a handful of walnuts and a tablespoon of ground flaxseeds, can provide all you need but if you want to take a vegan supplement, look for EPA/DHA on the label and choose one produced from algae – the same place that fish get their omega-3s from.https://viva.org.uk/health/health-articles/do-vegans-need-supplements/
