00:00 Introduction
01:02 Zinc's Roles In The Body
03:21 Why Zinc Deficiency Is Common
06:39 Zinc Supplementation
08:05 Zinc Dosage
09:16 Zinc Supplement Forms
Zinc is one of the most important trace minerals in the body. Unfortunately, zinc deficiency is very common today and can lead to wide-ranging problems. In this video, I want to talk about what exactly zinc is, its roles in the body and how to get enough of it, which means we will talk about zinc supplementation at the end of this video.
Let’s start by discussing what zinc is and why we need it.
Zinc is an essential dietary mineral, meaning we need to get it from food and cannot produce it ourselves. Unlike the macro minerals, for example magnesium or calcium, which the body needs a lot of every day, zinc is a trace mineral, meaning the body needs only a fairly small amount of it. The RDA for adult women is 8 milligrams of zinc per day, while adult men need 11 milligrams per day. That doesn’t mean zinc is less important than other nutrients however. In fact, it is involved in many bodily functions. The most important of which are:
Immune function:
A stronger immune system is probably what zinc is best known for. That’s because it is necessary for immune cell function and cell signaling. It can also have antioxidative properties meaning it reduces oxidative stress and can eliminate free radicals in the body, similar to vitamin c. For example, one study showed that an intake of around 80 mg per day of zinc can reduce the length of the common cold by up to a third.
Growth
Next. To its importance for the immune system, zinc is also vital for the normal growth and development of the reproductive organs and brain. Research has linked zinc deficiency decreased growth,, impaired memory, learning disabilities, and poor attention span. In turn, zinc supplementation produced very significant positive effects on both height and weight measures of children. And the effect was even greater among children who already suffered from stunted growth or were underweight.
Hormone Balance
Zinc is needed for steroid hormone synthesis, being a well-known catalyst for testosterone manufacture. In fact, testosterone is often called the male mineral because it is so important for male hormone health and of all the body parts, the prostate contains the highest concentrations. That said, women also benefit from it because it supports the production of luteinizing hormone, which spurs ovulation and helps with the hormone production needed to support pregnancy.
Skin Support
Your skin also holds a relatively high amount of about 5% of your total zinc. The reason for this is that it plays critical roles in collagen synthesis, and proper wound healing. Its antinflammatory properties also make it an important agent in the treatment for acne, burns, and other skin problems.
As you can see zinc is critical to health, and in summary its most important functions are:
- To support a strong immune system
- To enable growth and a healthy hormone balance
- and to act as an antinflammatory agent for example in the skin
If your body doesn’t have enough zinc, all of these aspects of your health suffer. Now, depending what source you read, some will claim that zinc deficiency is only a problem in the developing world and not in the developed world. From my experience, this is not true. In fact, I would go so far as to say zinc is one of the most deficient minerals in many people and it’s getting worse over time. The reason studies aren’t picking up this trend is because most institutions still rely on blood tests for mineral testing, when in fact you need to do a tissue analysis to spot a deficiency reliably. I know I say this a lot in my videos, but trust me when I say blood tests are very misleading. The come back fine in 90% of the cases even when people are already developing serious deficiencies. Your best option is a properly done hair analysis, which I will explain in more detail in a different video. Just as a side note, many websites will tell you that a clear and simple sign of zinc deficiency are small white spots on the fingernails. This is true, however I have found that many people without these spots also have a zinc deficiency, so please don’t rely on it.
The reason for the zinc deficiency epidemic is similar to that of magnesium, where food processing strips most of it away. That means you are left with very few quality sources of zinc. The best sources are red meats, such as lamb and beef. Chicken, turkey, eggs and fish also contain some.
