Vitamin D helps your body absorb calcium and helps to keep your skin and bones healthy. It also plays an important role in your immune system. Vitamin D deficiency is linked to fatigue, bone and muscle pain, as well as getting ill more often than usual.
Advanced iron profile
Your body uses iron to make haemoglobin — a part of red blood cells that carry oxygen around your body. If you don't get enough iron you might develop iron deficiency anaemia, which can affect your fitness performance. Tiredness, shortness of breath, and heart palpitations are signs you might be deficient.
Vitamin B12 (active and total)
Vitamin B12 is essential for a healthy brain and nervous system. It also works closely with folate to make red blood cells — these carry oxygen around your body. If you don't get enough vitamin B12, it can impact your endurance and performance.
Testosterone is a hormone that's essential for women and women. It's important for muscle mass and strength, bone health, and red blood cell production (these transport oxygen around your body).
Your liver plays a key role in digesting and metabolising food. This process helps provide energy for your body to use. If your liver isn't functioning correctly it can affect this process and your fitness levels. Poor liver health can also cause low energy levels.
Folate (vitamin B9)
Folate (vitamin B9) is needed for a healthy liver, healthy skin, hair, and eyes. If you’re deficient it can cause tiredness, pins and needles, heart palpitations, shortness of breath and muscle weakness.
