Ready to dive in? Let’s tee up!
How to Write About Testosterone Supplements
If you’re getting ready to write up your T-booster dietary supplement, here are some words of advice for you — straight from a professional testosterone supplements copywriter!
The first is, you can’t treat testosterone supplements like other categories. Similar to supplements for cholesterol, for libido, and weight loss, testosterone is one of those very sensitive categories that requires special care.
It’s ironic; “testosterone booster” is in itself a risky name for a supplement. Because it implies that simply taking the pill will raise one’s testosterone levels. That’s exactly the kind of language you should probably be avoiding if you wish to minimize risk.
You’ll also want to avoid mentions of testosterone replacement therapy (TRT) because that is in a medical sphere, which must be kept completely separate from supplements.
The same goes for “alternative treatments” and marketing claims related to erectile function (as well as erectile dysfunction). Only prescription drugs can treat doctor-diagnosed, blood test verified testosterone problems.
Testosterone supplements claiming to treat low testosterone are asking for trouble!
This risk is amplified if a testosterone boosting supplement wades into the dangerous waters of erectile function claims. Just consider how popular drugs for erectile dysfunction are, how powerful the Big Pharma companies that produce them are, and ask yourself: “Do I really want to poke that bear?” It’s not worth it!
Now, if you want to keep your testosterone boosting supplement claims clean and conservative, you would use a different style of language. Some examples of safer claims include:
- Helps to support healthy testosterone levels
- Helps maintain testosterone production
- Supports testosterone production
- Supplies important nutrients for testosterone synthesis
- Natural testosterone support
Sexy? Not really. Vague? Most definitely. But if you want to sell natural testosterone boosters on Amazon and remain in the good graces of the FDA and FTC, this is the tone you should aim for.
What to say: Testosterone, Test or T?
Great question. How should we refer to testosterone in supplement content? As a testosterone supplements copywriter, I have worked with quite a few companies in this space, all of which had different takes on terminology.
One especially popular online testosterone supplement insisted on using “T” only in their content. I don’t agree with this.
Whether you say “testosterone,” “test” (which is more sports nutrition oriented), or simply “T”, the Food and Drug Administration knows what you are talking about.
My advice: Use a mix of all these terms to cover all of the SEO permutations that will draw organic traffic to your site.

Testosterone Supplement Copywriting Examples
In this section, I will start sharing some of the good stuff!
I will begin with some content marketing: A testosterone booster index. This is an example of educational content in the t-booster space. In it, I list many of today’s most popular test boosters.
But instead of just empty marketing words, this content is helpful: It gives consumers at-a-glance education on what these herbs, vitamins, minerals and other common ingredients are, how they work, and what they do.
The kicker: each claim is linked to a credible research source (the numbered references are listed at the bottom of this article).
As I alluded to earlier in this article, evidence is critical when it comes to the more sensitive and risky categories in the nutritional supplement space — so sharing this research is one of the key factors for building trust with your consumers while paying respect to the FDA, FTC, Amazon and other important bodies that are interwoven in supplement sales. Samples follow:
Testosterone Booster Index – Sample of Supplement Content Writing
T-booster supplements may supply a single ingredient or multiple ingredients. Single-ingredient products can deliver a higher dosage of individual supplement components per capsule, but mega-dosing is often a bad idea with T-booster compounds. Individual supplements can also get expensive if you want more than one nutrient in your T-boosting regimen.
More popular are T-booster complexes, which blend many vitamins, minerals and botanicals into one product. In complexes, some ingredients directly boost testosterone levels; others may work indirectly or even address other aspects of men’s vitality.
In general, the idea is that these ingredients will combine to help men conquer common low-T symptoms like fatigue, lost sex drive, weight gain, brain fog and more.
Complexes can be a cost-effective way to get several T-boosters and related compounds in one supplement. But the best formulas – and this might be the real secret – are made to be synergistic. This means ingredients’ individual effects are magnified by others in the formula, making the compounds more powerful combined than when taken alone.
Ingredients in T-booster supplements:
Horny Goat Weed: This flowering Asian plant got its name when a farmer noticed that his goats had more sex after eating it. Horny Goat Weed supplies an active ingredient called icariin that was shown in early animal research to raise blood T-levels.(1) This T-boosting activity might contribute to Horny Goat Weed’s more widely known reputation as a natural “sex enhancer.”
Tongkat Ali: Also called “Malaysian Gisnseng” this root has shown anti-estrogen effects in animal research.(2) One animal study also found that tongkat ali raised the testosterone level in the testes after 30 days of supplementation.(3) The evidence supporting in animal studies complements human research that showed tongkat ali may improve semen volume, sperm activity and male potency.(4)
Bulbine Natalensis: A traditional African herb, Bulbine has long been used by the Zulu for libido support. In tribal practices, powdered Bulbine stem would be mixed with milk to make a virility-enhancing drink.(5) Animal research suggests Bulbine might help testicular and blood T-levels, and seems to exhibit anabolic and androgenic activities.(6) Bulbine has been linked to liver risks.
DHEA: Dehydroepiandrosterone (DHEA) is made in the adrenal glands and migrates to the testes. Here, it serves as a raw material for T production. Evidence shows DHEA declines with age: 70-year-old men, who often have low testosterone, have about 80% less DHEA in their blood than younger men.(7) Although DHEA supplementation is somewhat controversial, research shows it boosts and sustains free testosterone circulating in the blood.(8)
Tribulus: An aphrodisiac in ancient Asian traditions, Tribulus terrestris is now popularly used by athletes for lean muscle mass. A spiky plant, tribulus is also reputed to “spike” testosterone levels; however, evidence in this area is early at best. One study found that combining tribulus with androstenedione, chrysin, indole-3-carbinol (I3C), and saw palmetto did appear to boost multiple androgen male sex hormones, including testosterone.(9)
L-DOPA: Also called levodopa, this botanical compound may boost levels of Luteinizing Hormone (LH), which stimulates the testes to make testosterone. One animal study found that a single high-dose serving of L-DOPA significantly raised LH levels after only four hours. Researchers concluded that prolonged high-dose L-DOPA appeared to be associated with sustained blood LH levels.(10)
Mucuna Pruriens: Also known as “velvet bean,” Mucuna is an Ayurvedic plant with seeds that are a rich in levodopa (L-DOPA). In a human study of male subjects with fertility problems, Mucuna supplementation was found to significantly increase testosterone and LH blood levels, while also improving dopamine, adrenaline and noradrenaline status. Researchers observed that Mucuna could help to improve male fertility, since it also enhanced both sperm count and sperm motility.(11)
Oysters: Rich in protein, oysters are also a good source many important minerals, including zinc, selenium, magnesium and iron. Oysters also deliver several B vitamins. Famous for sparking men’s sex drive, oysters have been suggested to be a T-boosting food – a reputation that’s probably backed by their zinc and B-vitamin nutrition.
B Vitamins: Animal research shows low Vitamin B6 levels are tied to low testosterone levels. Scientists have even suggested low B6 intake may actually slow testosterone synthesis.14 B12 is another B-vitamin that may appear in T-boosters for its energy metabolism benefits. B vitamins can be challenging: We need a higher daily intake of them as we grow older, but they also get harder to absorb with age.15 It’s a good idea to supplement with absorption-enhanced forms of B6 and B12 when possible.
Magnesium: This mineral sparks 300+ life-sustaining reactions in the body, including protein synthesis, bone formation, muscle relaxation and testosterone boosting. In one study of male volunteers, researchers found “supplementation with magnesium increases free and total testosterone.”16 It’s worth noting that older men who may be in T decline have a harder time absorbing and retaining magnesium.(17) Bioavailable mineral forms, such as magnesium citrate, may be helpful for these populations.
Zinc: An essential mineral for masculine health, zinc supports prostate function, sperm activity and reproductive potency in men. Zinc is used by the Leydig cells in the testes to produce testosterone. Human clinical trials have found that young men with low zinc intake have lower blood testosterone levels and less semen volume.(18) These study results provide evidence for zinc’s potential role in male virility. Zinc may be depleted in the aging male body, and is a first-line supplement for maintaining testosterone levels.
Nettle Urtica: Also known as “stinging nettle,” this traditional European herb is popularly used by mature men to support prostate health, urinary comfort and sexual function. Nettle might be good for the prostate because it blocks aromatase, an enzyme that turns testosterone into estrogen.(19) By blocking this conversion, nettle may help men keep their T-levels up and estrogen down, supporting an ideal manly ratio while assisting with urinary symptoms.
Siberian Ginseng: Also known as eleuthero, Siberian Ginseng is an “adaptogen” herb that strengthens the body’s resistance to stress. Only weak anecdotal evidence suggests Siberian Ginseng may raise T-levels in mice. Eleuthero’s presence in individual supplements and stacks is more likely related to its well-documented benefits for energy, mental sharpness, peak physical performance and stress resistance.(20)
Fenugreek: This ancient Indian spice is one of the oldest cultivated plants in the world. Research has suggested that a standardized fenugreek seed supplement improved sex drive and helped maintain peak blood testosterone levels.(21) Fenugreek has also been suggested to have anabolic muscle mass and stamina-enhancing effects that may help with other goals of testosterone boosting regimens.(22)
Vitamin D: Most Americans fail to get enough of the recommended daily allowance of this important vitamin, famous for supporting immunity and bone density. Paradoxically, we need more vitamin D with age, but it also gets harder to absorb and synthesize as we age. This might mean that many men are missing out on D’s T-boosting benefits: Human clinical research has shown regular D intake raises blood levels of free testosterone, bioactive T and total T.23 Look for the D3 form of the vitamin, which is easier to absorb.
D-Aspartic Acid: Also called DAA, this amino acid influences the production and release of hormones. Animal studies have suggested DAA triggers release of LH and growth hormone from the pituitary gland; in the testes, it promotes the formation and release of testosterone.24 DAA seems to be one of the more effective T-boosters, with a strong human study finding it raised testosterone levels by 160%.25 DAACC, which is the chelated form of DAA, may be easier for the body to absorb and utilize.
Luteolin: An antioxidant flavonoid, luteolin is found in many fruits and vegetables, as well as in Traditional Chinese Medicine herbs. Luteolin may be featured in T- boosters because it blocks the aromatase enzyme that converts testosterone into the female sex hormone, estrogen.26 Like nettle, luteolin helps men optimize T-levels and keep estrogen in check – which may help delay andropause and its related symptoms.
Boron: This mineral, popularly taken for bone strength and joint comfort, may also have testosterone benefits. One study found that boron raises T while significantly reducing estradiol, a female sex hormone related to estrogen. These results led researchers to proclaim it was “the first human study to show an increased level of free testosterone after boron consumption.”(27)
Vitamin K: Known for keeping calcium in the bones and out of the bloodstream, this essential vitamin is also found in the testes, where it promotes testosterone synthesis. Animal research has found that Vitamin K deficiency correlates with low testosterone production.(28) Vitamin K supplements appear to reverse this problem, boosting T-synthesis and helping restore healthy levels.(29) There are several vitamin K forms; K2 is believed to have the highest activity and strongest potency.

Our cultured vitamins and minerals are complexed with absorption-enhancing cofactors that maximize their T support and masculine health benefits.
KSM-66® Ashwagandha, 300 mg
Ashwagandha is an Ayurvedic root herb traditionally used for physical and mental performance enhancement. Its active withanolides may help increase testosterone by:
- Bolstering resistance to the negative impact of stress on testosterone, including by blunting the release of stress hormone cortisol;
- Promoting the synthesis of LH and Follicle-Stimulating Hormone, which trigger T production;
- Providing antioxidant activity that protects serum testosterone as well as protecting the testes that produce T
SPORT T+ KSM-66® has been shown in human clinical research to:
- Increase LH by 34%
- Increase testosterone by 17%
Mucuna Pruriens (15% levodopa), 150 mg
Mucuna Pruriens is a male tonic herb that supplies levodopa (L-DOPA), an effective active ingredient for masculine health and testosterone production:
- L-DOPA stimulates the brain to release gonadotropin-releasing hormone (GnRH);
- GnRH signals the pituitary gland to produce LH;
- LH promotes increased testosterone synthesis in the testes
Mucuna may further support a masculine hormone body-state by acting as a mild inhibitor of the T-diminishing hormone prolactin while optimizing growth hormone. Research suggests Mucuna significantly increases T in men with low sperm count.
SPORT T+ Mucuna Pruriens is strong. Velvet bean seeds are 4.2% levodopa; SPORT T+ Mucuna Pruriens is 15% levodopa. One SPORT T+ serving supplies levodopa equivalent to 8.6 g of velvet bean.
D-Aspartic Acid Calcium Chelate (D-AA-CC), 300 mg
D-Aspartic Acid Calcium Chelate (D-AA-CC) is an amino acid that regulates sex hormones throughout the endocrine system. It supports testosterone production by:
- Helping pituitary gland produce growth hormone; LH and growth hormone;
- Supporting gonadotropin-releasing hormone (GnRH), LH and Follicle Stimulating Hormone (FSH);
- LH and FSH signal for increased production of testosterone
SPORT T+ D-AA-CC complexes DAA molecules with calcium chelate for enhanced absorption and easier digestion.
Luteolin (from orange fruit extract), 30 mg
Luteolin is a botanical antioxidant that promotes ideal testosterone levels by blocking aromatase, an enzyme that converts T into estrogen. This bioactivity is helpful for:
- Stacking with D-AA-CC: Luteolin limits D-AA-CC’s female hormone activity while allowing its male hormone activity to work to the fullest effect
- Men over 30: Luteolin helps regulate aromatase’s testosterone-to-estrogen conversion rate, which increases as men grow older and is linked to age-related T decline
Take SPORT T+ in conjunction with strength training and sport nutrition supplements to support healthy testosterone production and peak athletic performance.
SPORT T+ helps keep more testosterone circulating for a longer time. Take it to upgrade your male testosterone activity, muscle strength and full masculine power.
Who should take SPORT T+?
SPORT T+ is designed to be taken by men, only. This formula can help men of all ages, including the aging male, who may suspect they have T deficiency and are seeking to safely and naturally raise testosterone levels. SPORT T+ may assist with the secondary benefits of a more masculine hormonal status, including physical strength, muscle mass and recovery, helping to increase energy, weight management, body fat metabolism, sexual function and virility.
How do I take SPORT T+?
Take 2-4 capsules daily. For best results, take 1-2 capsules with your first meal of the day or before your workout, and then 1-2 capsules with your second meal or after your workout. For best results, SPORT T+ should be taken as part of an overall fitness regimen including strength training and cardiovascular exercise. These activities work in conjunction with SPORT T+ to raise testosterone levels higher than with supplementing alone.
Why does SPORT T+ not supply fenugreek?
Fenugreek is one of the common ingredients in natural testosterone boosters and virility supplements, and evidence suggests it may effectively support healthy T levels in men with testosterone deficiency. Part of the reason it works is by blocking 5-alpha-reductase that converts T into another hormone called Dihydrotestosterone (DHT), thereby sustaining circulating T levels. The problem: DHT is another important male sex hormone that works together with T. Fenugreek benefits for testosterone are offset by its potential to reduce masculine DHT.
SPORT T+’s 300 mg of DAA seems low compared to other testosterone boosters. Why is this?
A recent study suggested DAA is only effective for a short period of time at high doses at 1500 mg – 3000 mg, and can actually reduce testosterone at excessively high 6000 mg doses. SPORT T+’s conservative 300 mg dose of DAA as enhanced potency D-AA-CC is intended to maintain your testosterone level to promote endocrine system signaling over time, thereby eliminating the need for cycling.
Is SPORT T+ safe?
Like all our supplements, SPORT T+ is designed to be safe for daily use and long term health. SPORT T+ achieves clean health benefits and testosterone boosting results by using pure, potent ingredients that are dosed appropriately and in line with clinical research. Free of GMOs, gluten, soy, colorants, preservatives and other additives found in low-quality over the counter supplements, SPORT T+ is safe and beneficial for raising serum T, even with long-term use.
Is SPORT T+ legal?
Yes. SPORT T+ is a safe, natural and legal form of T supplementation. This is important because some testosterone boosters are not legal in all countries, while others may be banned by professional, amateur and collegiate SPORTs organizations. SPORT T+ ingredients are legal all over the world, and are tested for banned substances that may be present in other testosterone supplements.
