Cod liver oil is a potent source of the essential fatty acid, omega-3, alongside vitamins A and D.

Vince Gironda was known for his ‘Hormone Pre-Cursor’ diet, which comprised of a stack of supplements all in favor of boosting testosterone production. 

At the top of the list was vitamin A and vitamin D - 2 components of the NSP Cod Liver Oil formula.

Vitamin A

Vitamin A is a fat-soluble vitamin, meaning it requires fat for transportation around the body. 

Therefore, bodybuilders and fitness enthusiasts on a low-fat diet may find themselves deficient in this particular nutrient. 

As well as helping to enhance immune function, and bone growth, vitamin A may also help enhance muscle growth by aiding testosterone production and protein synthesis. 

Vitamin D

Vitamin D deficiency is the most common nutrient deficiency across the world, and can lead to a myriad of health disorders, such as: - 

• Muscle weakness
• Bone loss
• Depression
• Weakened immune function
• Fatigue

Vitamin D can directly help improve body composition by helping to optimize testosterone level and insulin sensitivity. 

Furthermore, its crucial role in immune function can help to accelerate recovery from training as well as build a tolerance to intense exercise.

Omega-3

Omega-3 fatty acids are essential fatty acids, which the body cannot synthesize and therefore must be consumed in the diet. 

They play an important role in cardiovascular health by lowering triglyceride levels and blood pressure. 

In addition, they also display powerful anti-inflammatory effects and can have a very positive effect on mood. 

They are typically found in fatty fish, such as salmon and mackerel, as well as certain plant sources, including flax and walnuts. 

Sadly, omega-3s are not consumed as frequently as they once were, and in their place is an abundance of the ‘omega-6’ fatty acids, which are predominantly found in vegetable oils. 

Whilst omega-6 fatty acids are also classed as ‘essential’, an imbalance between them and omega-3s can create pro-flammatory conditions, which may harm your health, recovery, and body composition. 

Supplementing with omega-3 may help to overturn this, and create an environment more conducive to shaping your body. 

Research has revealed they may help you experience less muscle soreness and even increased muscle growth by promoting muscle protein synthesis. 

Furthermore, it can help to improve insulin sensitivity and blood sugar control, which can result in enhanced energy levels and accelerated fat loss.
