It’s ‘pointless’ Taking Supplements Your Body Doesn’t Need

Can the wrong diet cause hair loss? Two Nutrient Deficiencies That Cause Hair Loss

Unless you are deficient in a certain nutrient, it’s “pointless” taking a supplement, Lambert said because, “the body will only take what it needs.”

Many people opt for multivitamin tablets, which can be counterproductive because the vitamins and minerals compete and it’s too much for the body to use in one go, Lambert said.

“It can really disrupt your digestive system,” she said.

Lambert said she often sees clients who are struggling with stomach cramps and think they have IBS, but once they stopping taking their multivitamin, the problem goes away.

Vitamin D And Hair Loss

A new study from India found that 86 percent of men with androgenetic alopecia had low vitamin D levels.

Some scientists are finding that low levels of vitamin D are linked to higher death rates from Coronavirus .

Vitamin D deficiency has been blamed for hair loss in select cases. Usually, this type of hair loss is temporary. Some researchers believe that vitamin D supplementation can reverse hair fall and lead to hair regrowth in select cases.

The role of vitamins and minerals in hair loss is important. During the past decade, vitamin D has been in the news more so than any other vitamin. Its deficiency has been touted as the reason for dozens of human health problems. These include rickets, osteoporosis, teeth loss, depression, cancer, high blood pressure and multiple sclerosis.


For most such health related problems, there is insufficient evidence that a vitamin D deficiency caused the condition in the first place. Nor is there concrete evidence that vitamin D supplementation causes any significant improvements in most such health problems.

Having said that, there are some conditions where prolonged vitamin D deficiency has been proven to have a strong causative effect.

And there exist a number of other conditions where there is some evidence of the importance of a sufficient intake of vitamin D. After all, most plants and animals need direct sunshine in order to thrive.

The Benefits Of Vitamin A For Your Hair

The body needs Vitamin A, period! Your bodys cells require Vitamin A for growth. Since hair is actually the fastest growing tissue in the body, it needs a lot of help from vitamins, minerals, and nutrients to do so.

Taking Too Much Vitamin C Can Cause Digestive Issues

Overdoing water-soluble vitamins is less dangerous than overdoing fat-soluble ones, but overdosing on vitamin C, for example, while rare, can still cause nausea, diarrhea, and stomach cramps, according to Lambert.

Vitamin C has many benefits, including keeping the immune system healthy, but most people don’t need a supplement if they’re eating a decent amount of fruit and vegetables, she said.

An orange or a cup of strawberries, chopped red pepper, or broccoli provides the recommended daily 65-90 milligrams of vitamin C, according to the Mayo Clinic.

A post shared by RHIANNON LAMBERT BSc MSc RNutr

Lambert and other experts recommend a “food first” approach to nutrition, because it’s easier for your body to absorb vitamins from food, rather than in supplement form.

Some capsules don’t disintegrate quickly enough for the body to use the nutrients, especially if the coating is shiny or waxy, she said.

Do Hair Vitamins Genuinely Work

Best Vitamins For Hair Loss Review

Growing and maintaining overall hair health is complicated, as many internal and external factors influence the process. Despite this, many swear by hair vitamins and supplements to help support hair health throughout the day.

Essentially, hair supplements work by producing keratin and supporting the internal structural structure of hair, like cysteine, proline, threonine, and arginine, which are amino acids. In most processes throughout the body, keratin production is impacted by free radicals and oxidative stress-both, which are alleviated or mitigated by antioxidants.

The real question here is, do they truly work? Well, there is no clear answer. While essential nutrients and bioactive could support the synthesis and protection of hair, there arent many clinical studies taking into account healthy populations. Research on hair supplements for the average person is scarce, with most published studies dealing with people with various nutrient deficiencies. It is also difficult to track how much they influence hair growth since their mechanism is more about creating optimal conditions for hair health.

Furthermore, the effectiveness of supplements depends in part on the formulation. However, customer reports can still be considered valid: Peer-reviewed publications are ideal, but many customer reports are also worth considering.

So We Really Have Two Separate Kinds Of Vitamin D3 That Perform Two Functions Simultaneously

And the less modified calcifedioloperates more in the fat and muscle cells regulating metabolism and heat production.

So if you have excess body fat, taking too much vitamin D3 will keep you from being able to burn it off.

And even if youre skinny, too much vitamin D3 will still lower your general metabolism, making you tired.

Role In The Skin Muscle And Bone

More collagen in the skin increases its elasticity and water content, which prevents both dry skin and wrinkles. Well-hydrated skin is more likely to withstand the usual wear and tear it experiences as people go about their day, is less likely to experience issues like acne breakouts, and helps the skin keep its structure.

Because collagen is also an integral part of muscle tissue, it also helps with protecting joints and vulnerable internal organs from impacts. Studies have suggested that collagen deposits in the cartilage can help trigger a loop that stimulates the bone to produce more collagen. This can help treat chronic conditions like joint pain.

Collagen may also help prevent or reduce the symptoms of osteoporosis, especially with older patients. Because collagen makes up so much of the bones in the body, researchers have suggested that older individuals can greatly benefit from collagen supplements. In particular, clinical trials that have combined collagen supplements with calcium have shown promising results.

Vitamin D And Hair Growth

Vitamin D is a fat-soluble vitamin made in the skin. When your skin comes into contact with the suns UV light, it becomes activated and travels to the liver and kidneys. It then undergoes further chemical reactions to produce its final active form. This nutrient helps control calcium and phosphorous levels in the blood, regulates the immune system, and exerts anti-inflammatory properties.

Hair follicle cells contain receptors for vitamin D, making it important in hair growth. People with genetic mutation of this receptor, like those with type II rickets, have very little to no hair growth on their bodies.

Evidence suggests that vitamin D deficiency is linked to alopecia areata, an autoimmune form of hair loss. A meta-analysis found that the average vitamin D level in alopecia areata patients is significantly lower compared to people without this type of hair loss. Additionally, alopecia areata patients were more likely to be vitamin D deficient.

This study did not find a significant link between vitamin D levels and the severity of hair loss. However, a more recent test in 45 adults found a negative correlation between vitamin D levels and the severity of alopecia areata. Another study showed the same results in 50 individuals with androgenic alopecia , with a correlation between vitamin D deficiency and the severity of the disease in these patients, as well.
