There’s no question that one thing your progress in the gym is determined by is how healthy you are. For example, If you’re battling a cold or other illness, or just lacking in key vitamins and minerals, you won’t have a good workout, let alone make good progress. The health of your immune system is key to how healthy you are. Vitamin C is one of the most important vitamins you can take if you want a healthy immune system. Yet C is a supplement that might be lacking in the average gym rats supplement program. Why take chances with your health? Take 5% Nutrition Core Vitamin C 1000!

What Are The Benefits Of Vitamin C?

The benefits of 5% Nutrition Core Vitamin C 1000 include:

Vitamin C Is A Potent Antioxidant

Antioxidants are compounds that promote better health by fighting free radicals. If you ignore the health of your immune system, you can experience a number of health-related problems. Since C is an antioxidant, it improves the body’s natural ability to fight against free radicals. (1, 2)

C Enhances Your Immune System 

As noted, Vitamin C supports immune system health. Along with its impressive antioxidant benefits, it also promotes the production of white blood cells. The combination of vitamin C’s antioxidant and immune system benefits gives you protection against colds and oyster illnesses. (3)

Vitamin C Supports Collagen Production 

Another important function of Vitamin C is the role it has in collagen synthesis. For those who may not know, collagen is actually the most abundant protein in the body. In fact, collagen is the protein that the body uses for hair, nails, skin, and connective tissue. (4)

It Supports Dopamine Production

Vitamin C is a key component in dopamine production. What is dopamine? It is a neurotransmitter that supports motivation and a positive mood. Let’s be real, both your workout and your day will go better with an elevated mood. Plus, increased motivation will mean you have more desire to work out. (5)

Vitamin C Is Involved In The Production Of Nitric Oxide

Vitamin C is involved in nitric oxide production. It helps increase the activity of the enzyme known as eNOS (endothelial nitric oxide synthase). eNOS is the enzyme that increases the production of nitric oxide. That means more intense pumps and enhanced nutrient delivery to your muscles. (6)

5% Nutrition Core Vitamin C 1000 - Ingredient Profile

5% Nutrition Core Vitamin C 1000 goes far beyond those other “Core” products by including supporting ingredients. Who else but 5% Nutrition does that? Let’s look at this exceptional formula.


One serving (2 capsules) provides:

Vitamin C - 1g

As you may know, Vitamin C is a water-soluble vitamin. The body does not make it so your diet and supplements must supply it daily. 5% Nutrition Core Vitamin C 1000 provides a full gram per serving. (7)

Citrus Bioflavonoids 50% - 10mg

This ingredient occurs naturally in the rind of citrus fruits, rose hips, and black currants. Bioflavonoids enhance the effectiveness of vitamin C and are often included in vitamin C complex products. (8)

Zinc Citrate - 10mg

Zinc is an essential mineral with quite a few impressive benefits. Similar to Vitamin C, Zinc supports the health and function of your immune system. It’s also involved in the metabolism of protein and your body’s natural production of testosterone. These reasons make it an essential part of this advanced Core formula. Clearly, you can see what separates our Core line from the competition. (9)
