The Best Manganese Supplements You Don’t Want to Miss (and Where to Buy Them)

I’ve always been mindful of getting the right nutrients, but I never paid much attention to manganese—until I realized how important it is for bone health, metabolism, and antioxidant support.

Although eating a balanced diet helps, I found that some people, including myself, may need a little extra boost, especially if their diet lacks manganese-rich foods or if they have certain health conditions.

But here’s the problem: not all manganese supplements are created equal.

Some are poorly absorbed, while others contain additives that are not necessary.

I’ve spent time researching, testing, and comparing different options to find the ones that actually work.

In this guide, I’ll share my top four picks—supplements that I’ve either tried myself or thoroughly reviewed based on quality, absorption, and customer feedback.

If you’re looking for a reliable manganese supplement to support your health, you’re in the right place.

Here, I’ll share why manganese matters, my journey with it, and top 4 supplement picks that I’ve tried and tested.

So, let’s quickly jump into my top four recommendations!

Why Manganese Is a Big Deal

Manganese is a mineral your body needs in small amounts to help regulate blood sugar, strengthen the bones, and fight off stress in your cells.

It works by supporting enzymes that help process glucose and then protects your body from damage caused by oxidative stress.

Who can benefit from manganese?

  • If you experience sugar cravings
  • Have stiff joints and weak bones
  • Feel tired in the afternoons
  • Or are concerned about prediabetes

What Research Says. Several studies have investigated the relationship between manganese and bone health, and glucose metabolism. Here are a few examples:

1. Manganese Deficiency and Toxicity: Effects on Carbohydrate Metabolism in Rats.

  • This study found that both manganese deficiency and toxicity can disrupt carbohydrate metabolism. Rats with manganese deficiency could not produce enough insulin, and they had abnormal glucose tolerance, while those with manganese toxicity experienced rapid changes in blood glucose and insulin levels. [1]

2. The Link between Trace Metal Elements and Glucose Metabolism: Evidence from Zinc, Copper, Iron, and Manganese-Mediated Metabolic Regulation.

  • This study shows how important manganese is in glucose metabolism, noting that both deficiency and high levels can interfere with glucose homeostasis. Manganese is essential for insulin production and secretion, and taking its supplements has been found to improve glucose intolerance in diabetic models. [2] 

3. U-Shaped Association between Plasma Manganese Levels and Type 2 Diabetes

  • This study observed a U-shaped relationship between plasma manganese levels and type 2 diabetes risk, suggesting that both low and high levels of manganese could lead to an increased risk of developing the disease. This means that it’s important to keep manganese levels just right to help with glucose metabolism in the body. [3]

Manganese and Bone Health. Research points to Mn as being really important for bone formation and remodeling. Here are some few examples:

1. Bone Remodeling. Manganese is thought to influence osteoblast (bone-forming cells) and osteoclast (bone-resorbing cells) activity. Studies suggest Mn can modulate the expression of genes involved in bone formation and resorption.

  • While a definitive human study directly linking manganese intake to gene expression changes in bone cells is lacking, research using cell cultures and animal models supports this. For example, studies have investigated the role of Mn in the differentiation of mesenchymal stem cells into osteoblasts. [4]

2. Oxidative Stress: Mn-containing enzymes, like superoxide dismutase (MnSOD), protect cells from oxidative damage. Oxidative stress is implicated in bone diseases like osteoporosis. MnSOD in bone mitochondria may protect osteoclasts from oxidative damage.

  • This link is supported by studies showing the importance of MnSOD in mitochondrial function and its role in reducing reactive oxygen species. Oxidative stress is indeed a key factor in osteoporosis development. [5] 

3. Mineralization. Manganese may be involved in bone mineralization. A study investigated the relationship between blood manganese levels and bone mineral density (BMD) and bone mineral content (BMC) in adults. The study found a significant inverse relationship between higher blood manganese levels and lower BMD/BMC, mainly in the femoral neck and total body.

  • This study found that women, especially those between 50 and 70 years old, were more likely to have weaker bones if they had high levels of manganese in their blood. This suggests that high blood manganese levels might increase the risk of osteoporosis, which is a condition where bones become weak and brittle. The researchers say more studies are needed to figure out how much manganese is safe to eat without harming our bones.

4. Clinical Studies. Human studies are limited. Some have investigated Mn supplementation on bone mineral density (BMD) in postmenopausal women with mixed results. Some studies suggest that combining calcium (Ca), zinc (Zn), copper, and manganese (Mn) is more effective than calcium alone in preventing spinal bone loss. But, other studies have reported no significant effect of manganese supplementation on BMD. [6] [7]

These studies all point to the idea that having the right amount of manganese in is crucial for glucose metabolism and keeping your bones strong, and may influence the risk of developing type 2 diabetes.

My Journey with Manganese Supplements

A few years ago, in my early 30s, I started noticing some frustrating changes in my body.

My energy levels were fluctuating wildly—some days, I’d feel fine, but other days, I’d crash by mid-afternoon.

My joints felt stiff, and my bones became weaker, in the mornings, making simple things like getting out of bed or going for a walk uncomfortable.

The biggest shock came when a routine blood test showed that my blood sugar is creeping into the pre-diabetic range.

That moment hit me hard. I knew I had to take action. I started researching ways to naturally support my blood glucose and bone health.

That’s when I found manganese.

At first, I didn’t think much of it—it’s not a mineral you hear about often.

But the more I read, the more it made sense. Manganese is a trace mineral that strengthen bones and helps regulate how the body processes sugar. It seemed like exactly what I needed.

After talking to my doctor, I decided to try a manganese supplement. I won’t pretend it was an overnight miracle, but after a few months, I’ve seen some changes.

  • The stiffness in my joints started easing up. I remember waking up one morning, stretching, and realizing I wasn’t as sore as usual. That was the first sign something was working.
  • My energy felt more stable throughout the day. I no longer had those crashes where I’d struggle to keep my eyes open.
  • The biggest breakthrough came when I went back for another blood test. My doctor looked at my results and smiled—my blood sugar levels had improved, moving me out of the pre-diabetic range.

That moment reassured me that I was on the right track. Of course, I didn’t rely on manganese alone. I also made changes to my diet and stayed more active.

But I truly believe manganese gave me that extra boost, supporting my body in ways I didn’t even realize I needed.

Now, it’s a regular part of my wellness routine, helping me stay active, energized, and in control of my blood sugar.

If you’re struggling with energy swings, stiff joints, or blood sugar issues, I’d say it’s worth looking into. For me, this simple addition made all the difference.

Good value, nice to get a decent amount of the mineral in one tablet. I take it every 2 days to help with physical frailty linked to joint hypermobility. Just why the tablets are so large for such a tiny amount (0.02g) I don't understand... this suggests a lot of fillers. They would be easier to take if smaller.

One happy customer said:

According to tests, I have low manganese and anemia (and it can be not only due to low iron, but also due to low manganese), and in complexes it is usually in small dosages. I'm glad I found it in this dosage, because... This is not a popular supplement, but it is extremely important.

One reviewer said:

I Got it for my shoulder tendonitis! Dr. Berg described it for shoulder tendonitis. I took my first pill today. will update my results after a month. nice small packaging and good pill size.
