Common Questions

Why does Strengthener Plus contain both zinc and copper?

Long-term zinc supplementation can reduce copper status. Strengthener Plus includes copper glycinate to help maintain a healthy zinc-copper balance.*

What forms of zinc are used in Strengthener Plus?

Strengthener Plus provides zinc from zinc picolinate and zinc citrate. These are used instead of lower-quality forms such as zinc oxide and are selected for their absorption and utilization.*

How do MSM and silica support hair, skin, and nails?

MSM provides sulfur used in structural tissues, while silica helps support collagen and the structural integrity of hair, skin, nails, bones, and connective tissue.* Strengthener Plus uses bamboo extract standardized to 70% silica.

How should I take Strengthener Plus?

Women: take 1 capsule up to 2 times daily. Men: take 1 capsule up to 3 times daily. Take with food.

Bioactive zinc formula for structural, immune and thyroid support.*

How It Works

Strengthener Plus™ is a special zinc formulation with important cofactor nutrients, including MSM sulfur, copper, B6, and bamboo extract (providing silica). The forms of zinc we use, picolinate and citrate, are the primary forms utilized by the GI tract for easy absorption, and are superior to zinc oxide or zinc gluconate. Zinc is an important mineral for immune health. Zinc is needed for the integrity and strength of various body structures, such as bones and nails (white spots on the nails may reflect a lack of zinc).* Mild acne may respond to zinc supplementation.*

Hair, skin, nails:  MSM sulfur is a helpful mineral for hair strength and skin. It works synergistically with zinc in these areas. In fact, zinc is required for MSM sulfur to work properly in the formation of healthy body structures. Strengthener Plus also contains copper and silica, which help to strengthen the collagen and bone structure. Silica is also the main component of the hair shaft. These nutrients can help to keep hair from falling out and strengthen skin.*

Stress, immune support:  Zinc, like MSM Sulfur, is active in hundreds of enzymes in human metabolism. Zinc is easily lost in sweat (during exercise) and is used in greater amounts under stress. Zinc is required for optimal function of the immune system. Zinc and sulfur work together to form the three-dimensional structure of antibodies, important immune system troops.*

Alcohol, toxins:  Zinc has also been shown to help reduce damage from alcohol consumption. It may be wise to supplement zinc if consuming any alcohol when trying to get pregnant.* Zinc, sulfur, and copper have been shown to help the body clear toxins, including heavy metals.*

Sex drive:  Sex drive in men or women is directly related to low levels of testosterone. Zinc supplementation has been shown to increase testosterone production and therefore improve sex drive. Men generally need 50-75mg of zinc per day, women need 25 - 50mg.*

Thyroid support:  Zinc is a co-factor mineral that needs to be adequate for thyroid hormone to perform at an optimal pace. A lack of zinc is known to reduce the activity of TRH (thyroid releasing hormone in the hypothalamus), in turn tending to depress thyroid hormone levels. Zinc participates in the conversion of T4 to T3, and zinc is needed to bind active thyroid hormone to the DNA of cells. Zinc is needed for immunity, sex drive, and maintaining leptin status while on a diet. It is lost in sweat and by stress. Our Strengthener Plus formula contains zinc in its most biologically active forms.* 

Copper and zinc balance: Supplementing with zinc over extended periods of time can develop a copper deficiency. This is another important reason that copper, in the high quality form copper glycinate, is included in this formula.

Good source of Zinc. Recommended supplement

I highly recommend this zinc supplement! It’s a high-quality source of zinc, enhanced with beneficial co-factors like Vitamin B6, Copper, and MSM Sulfur for better absorption and effectiveness.After just a few days of taking it, I noticed a reduction in inflammation and improvements in my skin and hair health. Zinc is one of the most common mineral deficiencies, and this product delivers noticeable benefits quickly.Capsule size is good and easy to swallow. Also does not have any smell or after taste.The inclusion of copper is especially important, as it balances zinc intake and prevents mineral imbalance.If you're looking for a good bioavailable, well-formulated zinc supplement, this is an excellent choice.

Anxious to report the effects on seasonal allergies

100 capsules, recommended women take 1-2 a day so there is about 1.5 month supply. Men take 2 a day.I ordered this for the methysulfonylmethane (MSM Sulfur) that is said to help reduce the effects of seasonal allergies. I am anxious to see if that is factual, will update after usage. This is the main ingredient listed.The bamboo extract is an added benefit, boasting healthy for hair, skin and nails. Second main ingredient.The capsules are average size, smaller than a paperclip. Should not have any problems swallowing.

Nice supplement--more than just zinc.

These capsules are supposed to help support stronger hair, skin , nails and bone. I could use some help with all of the above, so I was eager to try them. What I like about this supplement is that it's not just straight zinc. It also contains copper, vitamin B6, MSM and silica (from bamboo extract). All of these work together. The capsules are large but I have no trouble swallowing them as long as I take them with enough water. I take one each day after breakfast. I've had no stomach upset. It's far too soon to notice any results but I trust that these ingredients should help.

Nothing not to love

I have noticed my nails seeming a little bit thinner and feel like my hair has been a little slower to grow lately and maybe thinner as well. So I am excited to try something that might help with that. It's obviously not been long enough to give definitive proof one way or the other on results but the ingredients look good! The package was well sealed, in fact I had to break through the inner layer because I couldn't peel it off. Not complaining, would rather that than find it not fully sealed. Pills were all tightly packed. No open capsules in the bottle. They are not small, but they're far from the largest supplement I've seen. If your plan is to open them and put them in a smoothie or something, know there is a very slight bitter taste and just a tad sour like vitamin c. Though it would most likely would not be noticed in a smoothie.I love that all the stuff is in one capsule. I admit, when I see that a supplements serving size is two, it is always a bit of a let down. So bonus!

Nice product, I've used it for several years.

I have ordered this for several years 4 bottles at a time. The last time most of it was expired before I finished the first bottle and the same thing will happen again. I called the first time and was told the product was still good even though it would be a year before I would finish them. It is not my intention to buy almost expired supplements so will be looking for an alternative product.

Hi - We intentionally use short expiration windows on our products to ensure they are as fresh as possible. This usually is between 15 and 24 months after production. The Strengthener Plus currently has over 9 months remaining on the best by date, which is within the normal sell date. Obviously, there is a different dynamic when ordering large quantities of a product at once. We totally understand that you may not want to keep these bottles if you will not consume them before November. Please contact us, and we are happy to return the bottles and let you know when the next batch arrives.

Contains Zinc for Hair

I certainly need help for my hair as I’ve had a lot of hair loss and I’ve read that zinc is pretty important for hair. My diet has been horrible, so I’m hoping this will help. Easy to take. There are 100 capsules and you only need one a day so it will last you 100 days.

Great product!

These vitamins are a combination of ones that I already take to boost my immunity. These are easy to swallow and come in a well-sealed container. I highly recommend them.

Wellness Resources Strengthener Plus Supplements

Took a bit longer to get here than is usual but it came well packaged and I like it’s made in the USA. I primarily chose this supplement for its zinc and MSM content, aiming to support my hair and nails (I've noticed my skin becoming drier than usual and my nails developing ridges) while also giving my immune system a bit of a boost. The capsules are easy to swallow and haven't caused any side effects such as stomach upset. While it's too early to comment on long-term results, my experience so far has been positive. According to the directions, women should take "one capsule, up to two times per day," while men can take "one capsule, up to three times per day." So this bottle will last a little over 1 1/2 months for women and a little less for men.

Great supplement for Hair, Skin, and Nails

I got these supplements because I read zinc is important to skin, nail and hair health. It has other stuff in it too like b6, bamboo silica, copper and MSM. I'm trying to get my hair healthy and full again.So far these supplements seem good. No bad taste or aftertaste. I will keep taking them and see what happens. It can't hurt.They're currently $18.99 at the time of this review. I think that's pretty fair since you get multiple ingredients in 1 pill. You get 100 capsules. A serving is 2 capsules.. so 50 days worth. A little under 2 months. I wish they made it 120 capsules so you'd get the full 2 months.I will say it takes generally 6 weeks to see results from these type of things. So after 1 bottle you can see if it's worthing for you.

Simple complex

This is an average dose of zinc, good for maintaining levels. It has copper in it as well which would be great but zinc and copper fight for absorption in the body so absorption effects would be questionable. I actually mostly ordered these because I liked the added msm. Overall it’s a simple complex with a few good nutrients for immune and skin health

Not A Bad Choice

I took this supplement in its entirety before my review. I stopped taking my normal one and took this one instead. I usually don't have to listed to the directions and take with food but I did with this one. Other than that there were no adverse side effects. If you take 2 per day it will last a little under 2 months. That is an average price point for this type of supplement. I do like the original supplement I take better and would not switch.

Zinc Important and Beneficial

I like and believe it is important that it is Made in the U.S.A. Zinc is often prescribed by a doctor. Zinc is found throughout the body. The body doesn't store excess zinc, so it must be obtained from the diet. It's needed for immune function, wound healing, blood clotting, thyroid function, and much more. It also plays a key role in maintaining vision and might have effects against viruses.SAFE: When taken by mouth: Zinc is likely safe when used in amounts no greater than 40 mg daily. It is possibly safe when taken in larger doses, especially when used only for a short period of time. But taking doses higher than 40 mg daily might decrease how much copper the body absorbs. Taking very high doses of zinc is likely unsafe and might cause stomach pain, vomiting, and many other problems. Single doses of 10-30 grams of zinc can be fatal.It is also contains Bamboo extract which offers numerous health benefits that have been studied and demonstrated over the years.Additionally, if you have a pre-existing medical condition or are currently taking medications, it’s crucial to consult with your doctor before incorporating bamboo extract into your routine. Most importantly: I strongly believe it’s essential to consult your doctor before taking any supplements, as they can impact your health and how certain medications are metabolized in the liver. It’s always wise to speak with your physician or pharmacist before adding supplements to your routine. You can even bring the bottle with you and ask for a professional medical opinion.

Gender specific

I use supplements to help close the gap between modern nutrition levels in our food and the levels that were there when I was young. But, in my opinion, the supplement industry has both some of the highest integrity companies, and some of the lowest. So I try and give a detailed enough review to help you know the company and product better so you can determine for yourself whether or not you want to try this one out.Unfortunately, Amazon puts their sticker right on the bottle's label so I can't read all the information there.If used as directed it will last 50-100 days for women (1-2 capsules per day) and 33-100 days for men (1-3 capsules per day).The capsules are easy to swallow with water.I like my supplements to say organic, non-GMO, GMP-certified, 3rd-party tested, and made in the USA. This says none of those. The product page says batch tested (but does not indicated if it's by a third party), manufactured in the USA, and has a GMP stamp.I look into the supplement companies I use because I've come across so many questionable ones. The bottle has their phone number, and the product page says family-owned since 1985. Their wellnessresources site is functional and informative. I like when a company doesn't just put generic statements about quality and health, but (like this one) includes specific details about who they are and what practices they follow.I seem to take longer than most to see results when starting a new supplement, but I like the ingredients, including the absence of fillers and flow agents that many companies say they need to use, while the manufacturers of the highest quality supplements that I am aware of refuse to.Not a bad price, especially if it lasts 2-3 months.Thank you for reading, I hope it was helpful.

A Decent Supplement for Hair, Skin, and Overall Wellness

Please note that I am not a doctor and am not giving any medical advise. I only share my personal observations.I picked up Wellness Resources Strengthener Plus mainly for the zinc and MSM content, hoping it would support my hair and nails while also giving my immune system a little boost. I’ve tried various supplements in the past, but I liked that this one includes bamboo extract (which is supposed to be good for hair strength) along with vitamin B6 and sulfur-based MSM.After taking it consistently for a few weeks, I can’t say I noticed any overnight transformations, but I do feel like my nails are growing a bit stronger, and my skin seems less prone to dryness. My hair feels the same so far, though I know these things usually take time to show noticeable results. The formula is easy on the stomach, which is a big plus because some zinc supplements can be rough if taken without food. I usually take it with breakfast, and I haven’t had any issues.The capsules themselves are a standard size—not too big or difficult to swallow. There’s no weird aftertaste, and I haven’t experienced any negative side effects. It’s hard to say if it’s making a huge difference, but I do feel like it’s a solid addition to my routine, especially during colder months when I try to be extra mindful of my immune health.Overall, it seems like a good supplement with well-thought-out ingredients. It’s not a miracle pill, but if you’re looking for a combination of zinc, MSM, and bamboo in one place, this is a decent option to try. I’ll keep taking it and see if the benefits become more noticeable over time.
