Why TESTO CORE™ Exists
The daily nutritional gap most British men do not know they have
The Real Story
After 35, most British men notice a gradual shift. Not dramatic. Not sudden.
Less energy by mid-afternoon. Slower recovery after training. Heavier mornings than they used to be.
This is not weakness. It is a gap — a daily nutritional gap that a busy diet and limited UK sunlight quietly open over time.
Zinc. Magnesium. Vitamin D3. Selenium. The four minerals and vitamins with GB government-authorised claims directly relevant to men's normal physiology. Most British men are not getting adequate daily amounts of all four.
TESTO CORE™ is built to close that gap. Two scoops. 23 active ingredients. 10,000mg of formula that no capsule bottle on the market can carry.
The Numbers Inside Your Tub
What you get with every scoop
"The amino acid and antioxidant foundation"
Why Citrulline — Not Just Arginine
Significant amounts are broken down by the enzyme arginase in the digestive tract and liver before reaching the bloodstream. This limits how much actually arrives at the blood vessels where it is needed.
Citrulline bypasses arginase. It travels to the kidneys and converts into L-Arginine, which then reaches the blood vessels. Free Form = 100% citrulline per gram — no filler, no malate weight.
L-Citrulline — Free Form
1,750mg per scoop | 3,500mg daily- Free Form = 100% citrulline per gram — no malate weight, no filler
- Twice-daily dosing across two scoops maintains consistent plasma amino acid levels throughout the day
- Bypasses the arginase enzyme that limits oral L-Arginine absorption — far more reaches the bloodstream
- 3,500mg daily — a serious, visible dose that earns credibility with any informed male consumer
L-Arginine — Free Base
250mg per scoop | 500mg daily- Free-base form = maximum elemental arginine content per gram — no binders
- Works alongside L-Citrulline as part of the combined amino acid complex
- Together with Citrulline = 4,000mg total daily amino acid complex — a meaningful, visible combination
The Antioxidant Protection Layer
Two botanicals and a vitamin that protect the circulation system at the cellular level.
330mg daily. One of the richest plant sources of OPCs (oligomeric proanthocyanidins) — powerful plant-based antioxidants. Included for antioxidant cellular protection and traditional use.
600mg daily. Traditional East Asian botanical — 2,000 years of use in male vitality and wellness practice. Included as a premium traditional adaptogen botanical.
160mg daily. GB Authorised: "Contributes to normal collagen formation for the normal function of blood vessels." Also supports cellular protection from oxidative stress. ✅
Pine Bark Extract Traditional Use
165mg per scoop | 330mg daily | OPC ≥95%- One of the richest natural sources of OPCs — a class of powerful plant-based antioxidants that help neutralise free radicals before they accumulate and damage cells
- At OPC ≥95% standardisation — only the active portion, nothing else. A visible quality marker on the label
- No GB-authorised health claim is made for Pine Bark — included as a premium traditional botanical antioxidant
Vitamin C
80mg per scoop | 160mg daily | 200% NRV- Vitamin C is one of the most essential vitamins in the body — and one your body cannot produce on its own. It must come from diet or supplementation, every day
- In the circulation context, Vitamin C supports normal collagen formation for the normal function of blood vessels — a GB government-authorised claim
- Also acts as a potent antioxidant — protecting cells from the daily accumulation of oxidative stress
- Delivered at 200% NRV — double the daily reference value — across both scoops
✅ "Vitamin C contributes to the protection of cells from oxidative stress."
✅ "Vitamin C contributes to the reduction of tiredness and fatigue."
"Feed the nutritional foundation — naturally"
Three GB Government-Authorised Nutrients for Normal Testosterone
ZINC
15mg daily | 150% NRV
(7.5mg per scoop)
"Contributes to the maintenance of normal testosterone levels in the blood."
MAGNESIUM
36mg elemental daily | ~10% NRV
(from 300mg Magnesium Taurate)
"Contributes to the maintenance of normal testosterone levels in the blood."
VITAMIN D3
50µg daily | 1,000% NRV
(25µg per scoop)
"Contributes to the maintenance of normal testosterone levels in the blood."
WHY ZINC BISGLYCINATE — NOT ZINC OXIDE? Zinc Bisglycinate is amino acid chelated — dramatically superior absorption. Zinc Oxide absorbs at only 4–10%. You are getting substantially more of what the label declares.
WHY LICHEN D3 — NOT LANOLIN? Most D3 supplements use lanolin — derived from sheep's wool. TESTO CORE™ uses lichen — 100% plant-based and vegan-suitable. No compromise.
WHY MAGNESIUM TAURATE? 300mg Magnesium Taurate compound delivers 36mg elemental magnesium (~10% NRV). Superior absorption compared to magnesium oxide, which is poorly absorbed and can cause digestive discomfort.
BORON — 6mg daily: Included to support the formula's overall mineral balance alongside Zinc and Copper. No GB-authorised health claim is made for Boron.
COPPER — 2mg daily | 200% NRV: Included to maintain the healthy Zinc:Copper mineral ratio. High zinc intake can deplete copper over time. At 2mg daily, the balance is maintained. This is responsible formulation.
Zinc — Bisglycinate
7.5mg per scoop | 15mg daily | 150% NRV- Your body needs Zinc every day to maintain normal physiological functions — including normal testosterone maintenance
- Zinc deficiency is one of the most common nutritional gaps in adult British men — particularly those who train regularly, eat limited red meat, or follow calorie-restricted diets
- Delivered as Zinc Bisglycinate — the amino acid chelated form with dramatically superior absorption compared to zinc oxide (which absorbs at only 4–10%)
- At 150% NRV — 50% above the standard daily reference value. Your body has more than enough to work with every day
- Also contributes to normal fertility and reproduction, normal protein synthesis, and the normal function of the immune system
✅ "Zinc contributes to normal fertility and reproduction."
✅ "Zinc contributes to the protection of cells from oxidative stress."
✅ "Zinc contributes to the normal function of the immune system."
Vitamin D3 — from Lichen (100% Vegan)
25µg per scoop | 50µg daily | 1,000% NRV- Vitamin D3 is the single most commonly deficient vitamin in the UK adult population — limited sunlight for most of the year means the body cannot produce enough naturally
- Studies consistently show a significant proportion of UK adults have suboptimal Vitamin D levels, particularly in autumn and winter
- For men, Vitamin D3 has a specific and well-documented GB-authorised role in normal testosterone maintenance
- Delivered at 1,000% NRV daily — a meaningful level designed to ensure adequacy for British adults who cannot rely on sunlight alone
- Sourced from lichen — 100% plant-based. Most D3 supplements use lanolin from sheep's wool. This formula does not
✅ "Vitamin D contributes to normal muscle function."
✅ "Vitamin D contributes to the normal function of the immune system."
Magnesium — Taurate
150mg Magnesium Taurate per scoop | 300mg compound daily | 36mg elemental daily | ~10% NRV- Magnesium is one of the most functionally important minerals in daily human nutrition — involved in over 300 biochemical processes
- It plays a specific role in normal muscle function and physical recovery — particularly relevant for active men
- Delivered as Magnesium Taurate — superior absorption compared to magnesium oxide, which is poorly absorbed and frequently causes digestive discomfort
- Note on dose: 300mg Magnesium Taurate compound delivers 36mg elemental magnesium (~10% NRV). This is the accurate elemental figure that appears on the product label
✅ "Magnesium contributes to normal muscle function."
✅ "Magnesium contributes to the reduction of tiredness and fatigue."
The Traditional Botanical Vitality Complex
No GB-authorised health claims are made for these botanicals. They are included for their centuries of traditional use in wellness practice worldwide.
Traditional botanical with centuries of use in male vitality and wellness practice across multiple cultures. Included as part of the premium botanical complex.
Panax ginseng — over 2,000 years of use in Korean and Chinese traditional medicine. One of the most revered traditional botanicals in the world. Also supports the Pathway 4 stress resilience dimension.
The most famous herb in Ayurvedic tradition — used in Indian wellness practice for over 3,000 years. One of the fastest-growing supplement ingredients in the UK market today. Also supports Pathway 4.
Rare Himalayan mineral resin — formed over thousands of years from compressed organic plant matter. Traditional Ayurvedic use. Purified and heavy-metal tested. A high-perceived-value premium ingredient.
Native to the high Andean plateau of Peru. Black variety — the rarest of the three Maca types. Traditional use by Andean communities for over 2,000 years in energy and vitality practice.
"Power your cells from the inside out"
CoQ10 Natural Decline — A Normal Part of Ageing
CoQ10 declines naturally from your 30s — this is normal biology. TESTO CORE™ delivers 300mg CoQ10 per day in water-dispersible form. That is 3–6× the dose of most standard CoQ10 supplements on the market.
CoQ10 Ubiquinone — Water-Dispersible
150mg per scoop | 300mg daily- Coenzyme Q10 is a naturally occurring compound found in virtually every cell in the human body — particularly concentrated in tissues that demand the most energy
- Your body's natural CoQ10 production begins declining from as early as your 30s — a normal physiological process
- Standard CoQ10 is fat-soluble and absorbs poorly from a powder format. The water-dispersible form is micro-encapsulated specifically for effective delivery in this powder
- 300mg daily = 3 to 6 times the dose found in most CoQ10 supplements on the UK market. A meaningful, premium contribution
- Traditionally paired with Shilajit in Ayurvedic practice — both are included in this formula at meaningful daily doses
Shilajit Purified Extract Traditional Use
250mg per scoop | 500mg daily | Fulvic Acid ≥50%- Shilajit is a rare, naturally occurring substance found in the rock layers of the Himalayan, Altai and Caucasus mountain ranges — formed over thousands of years from compressed organic plant matter
- Used in Ayurvedic medicine for centuries — traditionally associated with energy, stamina and overall vitality
- At Fulvic Acid ≥50% — this is a concentrated, quality extract. Purified and tested for heavy metals
- 500mg per day — one of the highest daily doses available in a UK powder supplement. A differentiating premium ingredient
Selenium — L-Selenomethionine
50µg per scoop | 100µg daily | 182% NRV- Selenium is an essential trace mineral — your body needs it daily but only in very small amounts. Despite the small dose, its role in the body is significant
- Delivered as L-Selenomethionine — the organic, highly bioavailable form with superior absorption compared to inorganic selenium salts
- At 182% NRV — meaningfully above the full daily reference value
- The spermatogenesis claim is unique to Selenium — it adds a genuinely distinctive and relevant authorised claim for a men's vitality formula
✅ "Selenium contributes to the protection of cells from oxidative stress."
✅ "Selenium contributes to the normal function of the immune system."
The Daily B-Vitamin Energy Complex
16mg | 100% NRV
Energy metabolism ✅
1.4mg | 100% NRV
Hormonal regulation ✅
50µg | 2,000% NRV
Energy + fatigue ✅

10 Keys To Getting the Most From TESTO CORE™
📅 Consistency First
Take both scoops every day without gaps. The adaptogens and micronutrients build to meaningful levels over 8–12 weeks of consistent daily use.
😴 Prioritise Sleep — 7–8 Hours
Sleep is when the body does its most important recovery and maintenance work. The evening scoop's Ashwagandha and Magnesium support the conditions for quality rest.
🏋 Resistance Training — 3 Sessions/Week
Physical training is one of the most powerful natural stimuli for male physiology. TESTO CORE™ provides the nutritional foundation — training provides the signal.
🥩 Eat Healthy Fats Daily
Avocado, eggs, nuts, oily fish and olive oil. D3 and CoQ10 in this formula absorb significantly better when taken alongside meals containing healthy fats.
☀️ Morning Light — 10 Minutes Outside
Natural morning light supports your circadian rhythm — the internal biological clock that governs energy, alertness and sleep quality throughout the day.
🚫 Reduce Alcohol Intake
Alcohol impairs multiple aspects of male physiological health — reducing or eliminating it dramatically improves the environment in which this formula works.
💧 Adequate Hydration — 2.5L Daily
Every biological pathway works more efficiently when the body is well hydrated. The amino acid complex in particular functions in the context of healthy blood volume.
🗓 Plan for 3 Months
Commit to three tubs for the full experience. Micronutrient levels stabilise over 4–6 weeks. Adaptogens require 8–12 weeks of consistent use to deliver their traditional benefits.
🧠 Actively Manage Stress
The formula supports daily resilience from the nutritional side. Practical stress management — exercise, time outdoors, adequate sleep — completes the picture.
🍽 Take With Food
D3 and CoQ10 are fat-soluble — they absorb meaningfully better alongside a meal containing healthy fats. This is especially important for the evening scoop.
