Immune Support: 3 Supplements You Aren't Taking BUT Should Consider! (Vitamin D-3, Vitamin B-12 and Echinacea Extract)

Sometimes we all need a little help keeping our immune system at its peak performance. Our bodies are constantly fighting off germs and bacteria that we come into contact with, and factors such as stress, diet, and sleep can all affect our body's ability to keep us healthy. Below are some supplements that can help support your body's immune system, keeping you happy and healthy. 


What is Vitamin D3 and why is it necessary?

Sometimes called the “sunshine vitamin”, vitamin D3 is naturally produced by your body when you are exposed to sunlight. Responsible for regulating the absorption of calcium and phosphorus, and plays a key role in maintaining normal function of the body’s immune system, improving your body’s defense against certain diseases.

Vitamin D is also important for normal growth and development of teeth and bones, may play a role in mood regulation and hinder symptoms of depression.

When combined with a calcium supplement, may even help suppress appetite and aid with weight loss.

Who may have lower levels of vitamin D?

Some of the factors that may affect your body’s ability to produce enough vitamin D on its own include: 

  • Lack of exposure to sunlight (either by not spending enough time outside, being in an area with high pollution, or large buildings that block sunlight)
  • Using sunscreens
  • Having darker skin (higher levels of melanin reduce the amount of vitamin D your body is able to absorb)
Signs of vitamin D deficiency include:
  • Tiredness
  • Muscle/ bone aches and pains
  • A general sense of not feeling well
  • Stress/hairline fractures in bones (especially in legs, hips, and pelvis)

What is the recommended amount of vitamin D?

The daily recommended intake provided by the Institute of Food and Agriculture Sciences is approximately 600 to 800 IU (international units) per day. 

Can you take too much vitamin D?

Although uncommon, vitamin D levels can reach toxic levels by taking excessive amounts of vitamin D3 over an extended period of time.

Reaching dangerous levels of vitamin D is not possible through diet and sun exposure alone, however, vitamin D is stored in body fat and released slowly into the bloodstream, and for those who reach toxic levels of vitamin D, it may last months after you stop taking the supplement.
