Himmense BOOST vs Numan Testosterone Support: Which Formula Is Right for You? (2026 UK Comparison)

Quick verdict. Numan Testosterone Support is a well-marketed, affordable everyday supplement from a UK telehealth brand you probably already know for hair loss and weight loss meds. The formula is 11 basic vitamins and minerals plus a few generic botanical extracts, at moderate doses, for £28/month (£14 on subscription). It's a competent, entry-level option. BOOST contains 19 active ingredients (including 6 evidence-backed patented extracts like KSM-66®, Tesnor®, PrimaVie® and Testofen®), is made in the UK, and is dosed at one capsule a day. Numan is the entry-level pick. BOOST is the specialist-formula pick.

The choice you're actually making

You're not just comparing two supplements. You're choosing between two very different brand strategies.

Numan is a UK men's telehealth brand. Their core business is prescription treatments — hair loss (finasteride), erectile dysfunction (sildenafil, tadalafil), weight loss (Mounjaro, Wegovy) and TRT — dispensed through a CQC-regulated online clinic. Their supplement range is a low-cost add-on to that ecosystem. Testosterone Support is priced at £28 single-purchase, dropping to £14 on subscription, which puts it firmly in the "entry-level everyday supplement" bracket. The strategy is scale and brand recognition, not specialist formulation.

Himmense BOOST leads with an evidence-backed formula. 19 active ingredients, six of them patented and clinically-trialled extracts, made in the UK, dosed at one capsule a day. It's a specialist testosterone formula built by a nutritionist, not a companion product to a telehealth prescription business.

Both approaches sell supplements. Only one is built purely around the formula.

The cost question

This is where Numan wins on the headline — and it needs to be acknowledged upfront.

Numan's subscription price is £14/month. That's their pitch: a testosterone-support supplement for less than the price of two coffees a week. It's a genuinely competitive number, and the low-friction telehealth checkout doesn't hurt.

BOOST's best-value price is £26.24/month on the 12-month subscription — nearly double.

The question isn't whether Numan is cheaper. It clearly is. The question is what you're actually getting for the £12/month difference.

The telehealth-companion question

Numan's supplement range doesn't exist in isolation. It's part of a broader men's health ecosystem that includes prescription treatments for hair loss, ED, weight loss and — notably — TRT. If you're already a Numan customer for one of those, adding Testosterone Support to your basket is a one-click habit. If you're not, you may be receiving marketing designed to pull you into the ecosystem.

That's a legitimate model — Numan is CQC-regulated and their clinical service is real. But it does mean the supplement doesn't have to be a "hero product." It's an add-on. The formulation reflects that: 11 mostly-generic ingredients, no patented clinically-trialled extracts, no BioPerine bioavailability enhancer, no Magnesium Bisglycinate, and a low 100 IU dose of Vitamin D3 (the UK-recommended winter dose is 10μg / 400 IU — 4× higher).

BOOST is the opposite of a companion product. It's a specialist formula built to be the primary testosterone supplement, not the fourth item in a basket.

Where the formulas overlap

Both Numan Testosterone Support and Himmense BOOST include:

• Maca Root — for sexual desire, libido and stamina
• Tribulus Terrestris — traditionally used for libido and reproductive health
• Panax Ginseng — but at very different qualities. BOOST uses 100mg standardised to 50% ginsenosides — Numan uses a generic form without a stated standardisation
• Zinc — direct contributor to normal testosterone. BOOST uses Zinc Citrate (good bioavailability)
• Selenium — antioxidant support for Leydig cells and sperm
• Vitamin D3 — but at very different doses (BOOST 25μg vs Numan 2.5μg). Numan's dose is a quarter of the NHS-recommended UK winter dose
• Vitamin B6 — supports hormone regulation and testosterone production

The overlap is sensible on paper. In practice, extract standardisation, mineral form, and dose all determine whether an ingredient works — and this is where the two products diverge most.

Where BOOST goes further

Six patented, clinically-trialled extracts vs zero

Numan Testosterone Support contains no patented, branded ingredients. BOOST uses six:

• KSM-66® Ashwagandha (300mg, ≥5% withanolides) — proven to raise testosterone (typically 15–17%), improve muscle strength/size, libido, energy, and VO₂ max
• Tesnor® (200mg Cocoa Bean & Pomegranate Peel extract) — shown to increase free testosterone up to 48% and total testosterone up to 25%, plus improvements in sexual function, mood, and physical performance
• Testofen® Fenugreek (600mg, 50% Fenuside™) — clinically shown to increase free testosterone and improve libido, erectile function, energy and body composition
• PrimaVie® Shilajit (300mg, ≥50% fulvic acid) — shown to increase total testosterone up to 20% and free testosterone up to 19%
• ForsLean® Coleus Forskohlii (250mg, 20% forskolin) — associated with increasing testosterone +16.8%, reducing body fat and preserving lean muscle mass
• BioPerine® (5mg Black Pepper extract, 95% piperine) — clinically shown to enhance the bioavailability and absorption of co-administered nutrients by 30–200%

Numan has zero of these. That's the single biggest gap between the two formulas.

A meaningful dose of Vitamin D3

Numan provides 100 IU (2.5μg) of Vitamin D3. The NHS-recommended UK winter dose is 400 IU (10μg). BOOST provides 1,000 IU (25μg) — 10× Numan's dose and enough to help correct the deficiency most UK men have between October and March. This is the difference between a "checkbox" D3 inclusion and a functional one.

Nutrients for testosterone pathways Numan skips

BOOST includes bioactive folate (L-5-MTHF) and B12 (methylcobalamin) — both immediately usable by the body without conversion — to support healthy testosterone pathways via homocysteine regulation. It also includes antioxidants (Vitamin C, Vitamin E) that protect testosterone-producing Leydig cells and sperm from oxidative damage. Numan doesn't include these.

Magnesium (in the right form)

BOOST includes 110mg of Magnesium as Bisglycinate — the highest-bioavailability form. Correcting magnesium deficiency can raise free testosterone by 15–24%. Numan's Testosterone Support doesn't list magnesium at all.

BioPerine® for absorption

BOOST includes BioPerine® to enhance the absorption of co-administered nutrients by 30–200%. Without a piperine enhancer, the actual absorbed dose of any botanical extract is a fraction of the label figure. Numan doesn't include one.

One capsule a day, algae-sourced D3

BOOST: one capsule with food. Numan: two capsules a day. And BOOST sources its D3 from algae rather than the more common lanolin (sheep's wool) — same cholecalciferol, but genuinely vegan.

Made in the UK

Both brands manufacture in the UK. Numan is a UK-registered CQC-regulated telehealth company. BOOST is made in the UK to GMP and HACCP standards in a facility registered with the FSA, MHRA, FDA and the Organic Food Federation.

The pricing question, honestly

On price, Numan wins. There's no way around it. £14/month for a testosterone-support supplement is aggressive, and Numan is the cheaper choice at every tier.

The counter-argument isn't about the price — it's about what a testosterone supplement is actually for. If the goal is to tick a box and add "testosterone support" to a broader Numan basket alongside their prescription products, the cheap-and-convenient option makes sense.

If the goal is to actually move the needle on testosterone, energy, libido and body composition, £12/month more buys you six patented clinically-trialled extracts, a functional dose of D3 (10× Numan's), bioavailable Magnesium Bisglycinate, folate and B12 in their bioactive forms, an absorption-enhancing piperine extract, and half the daily capsule count.

For the price of one coffee a week, that's a meaningful upgrade.

Who Numan is right for

Choose Numan Testosterone Support if:

• You're already a Numan customer for another product (hair loss, ED, weight loss) and want a convenient add-on
• £14/month subscription is your absolute ceiling
• You're looking for a low-commitment starter supplement to see how you feel
• The specific inclusion of KSM-66®, Testofen®, PrimaVie® or Tesnor® isn't important to you
• You're getting Vitamin D3 elsewhere (Numan's 100 IU dose alone won't correct UK winter deficiency)

Who BOOST is right for

Choose BOOST if:

• You want an evidence-backed formula built around six patented, clinically-trialled extracts
• You'd prefer one capsule a day rather than two
• You want to target the symptoms of low testosterone — sexual function, libido, fertility, stress resilience, energy, mood, and overall performance — not just tick a "T-support" box
• You want a functional 1,000 IU dose of Vitamin D3, not a token 100 IU
• You want the highest-bioavailability forms of minerals (Magnesium Bisglycinate) and vitamins (bioactive folate and B12)
• You want an absorption-enhancing piperine extract to maximise the value of every other ingredient
• You want a fully vegan formula (including algae-sourced D3)
• You want UK-made, UK-registered, tested to UK food-law standards

Frequently asked questions

Is Himmense BOOST better than Numan Testosterone Support?
Based on formulation — BOOST is meaningfully more comprehensive: six patented, clinically-trialled extracts vs zero, 10× the Vitamin D3, functional magnesium in bioavailable form, and a piperine absorption enhancer. On price alone, Numan is cheaper. "Better" depends on which of those matters most to you.

Why is Numan so much cheaper?
Because it's an add-on product for a telehealth business, not a specialist testosterone formula. Numan's core revenue comes from prescription treatments (finasteride, sildenafil, weight loss meds). The supplement is priced to be a low-friction basket-addition, not a hero product. Cheap ingredients (no patented extracts, low D3 dose, no BioPerine or Bisglycinate Magnesium) keep it affordable.

Is Numan's 100 IU of Vitamin D3 enough?
No — not for most UK men, most of the year. The NHS specifically recommends 10μg (400 IU) daily during autumn and winter for all adults, and testosterone-relevant research typically uses doses of 25–50μg (1,000–2,000 IU) to correct deficiency. Numan's 100 IU is a quarter of the NHS baseline recommendation and roughly a tenth of the dose associated with T-level improvements. BOOST provides 1,000 IU (25μg).

Can I take BOOST and Numan Testosterone Support together?
Don't. There's overlap on Zinc, Selenium, B6, D3, and the botanical actives (Maca, Tribulus, Ginseng). Stacking would push several nutrients above evidence-based recommended intakes for no additional benefit. Pick one.

Is Numan Testosterone Support vegan?
Publicly listed as vegetarian on retailer platforms. BOOST is fully vegan (including algae-sourced Vitamin D3).

How long until I notice anything?
Most men start noticing changes (energy, sleep, recovery, sometimes libido) in 2–6 weeks. Strength and body composition effects take 8–12 weeks. Both products recommend at least three months of consistent use.

What makes a "patented" ingredient different from the generic version? A patented branded ingredient — like KSM-66® Ashwagandha or PrimaVie® Shilajit — is a standardised extract produced to a consistent specification, with its own peer-reviewed human clinical trials. A generic version of the same plant can have wildly varying active compounds, inconsistent purity, and often no clinical research behind it. You're paying for clinical certainty, not just the plant name.

The honest call

Numan Testosterone Support is a competent, affordable entry-level supplement from a well-run UK telehealth brand. If price is the decisive factor and you're happy with a checkbox-level testosterone formula, it's a reasonable pick — particularly if you're already inside the Numan ecosystem for another product.

But there's a real gap between "Testosterone Support" as a low-cost add-on and a specialist formula built around six patented, clinically-trialled extracts. For £12/month more (£26.24 vs £14.00 on best-value), BOOST gives you a formula that includes KSM-66®, Tesnor®, Testofen®, PrimaVie®, ForsLean® and BioPerine® — each with its own published human clinical trials — plus a functional 1,000 IU of Vitamin D3, Magnesium Bisglycinate, bioactive folate and B12, and the discipline of one capsule a day.

For most men, BOOST is the more complete, more convenient, and better-value choice in 2026.
