Potensal

Everything you need to know about Potensal

Have you noticed that your energy, drive or recovery are not quite what they were at 30? Testosterone is commonly described as drifting down by roughly 1 to 2% a year after that age, and many men start looking for gentle nutritional support. Potensal is a food supplement in capsule form built around exactly that idea: men's vitality and healthy testosterone balance as the years go by.

Each capsule combines two nutrients with recognised roles, niacin and zinc, with a blend of amino acids and plant extracts. The line-up is L-citrulline, L-carnitine, Mucuna pruriens seed extract, maca root extract, maritime pine bark extract, grape skin extract and saffron stigma extract. Together they add up to 601 mg of declared actives per capsule. The legal manufacturer is not specified by the supplier, so the product is listed here under the Potensal name.

The positioning is straightforward. Zinc contributes to the maintenance of normal testosterone levels in the blood, and niacin contributes to normal energy-yielding metabolism and to the reduction of tiredness and fatigue. The amino acids and botanicals are included because they are studied in relation to blood flow, stamina, mood and antioxidant protection.

Potensal is aimed at adult men who want nutritional support for energy, vitality and active ageing, and who already take care of the basics: a balanced diet, regular physical activity and good sleep. It is one capsule a day, currently priced at £36.65, and it is not a medicine or a treatment for any condition.

What is inside Potensal

Ingredient	Dosage	Role
Vitamin B3 (niacin)	20 mg (125% NRV)	Coenzyme precursor (NAD/NADP) that contributes to normal energy-yielding metabolism, normal functioning of the nervous system, normal psychological function, the maintenance of normal skin and the reduction of tiredness and fatigue.
Zinc (zinc oxide)	11 mg (110% NRV)	Essential trace mineral that contributes to the maintenance of normal testosterone levels in the blood, normal fertility and reproduction, normal macronutrient metabolism, normal immune function, normal cognitive function and the protection of cells from oxidative stress.

L-carnitine	150 mg	Amino-acid derivative that carries long-chain fatty acids into the mitochondria to be used for energy production; studied in relation to fat metabolism, physical and mental fatigue, exercise recovery and sperm quality.
Maritime pine bark extract (Pinus pinaster)	100 mg	Source of proanthocyanidins and other polyphenols studied for antioxidant activity, microcirculation, nitric oxide availability and male sexual function (often researched in combination with L-arginine).
Mucuna pruriens seed extract	100 mg	Tropical legume seed naturally containing L-DOPA, a precursor of dopamine; traditionally used in Ayurveda and studied in relation to male fertility parameters, testosterone levels, stress, mood, motivation and sexual wellbeing.
Maca root extract (Lepidium meyenii)	50 mg	Andean root traditionally used as an adaptogen for vitality, stamina and libido; contains glucosinolates, macamides and polyphenols; studied in relation to sexual desire, energy, mood and semen parameters, without direct effect on circulating testosterone.
Grape skin extract (Vitis vinifera)	15 mg	Source of polyphenols such as resveratrol, anthocyanins and proanthocyanidins, studied for antioxidant activity, cellular ageing, and cardiovascular and metabolic health.
Saffron stigma extract (Crocus sativus)	5 mg	Spice extract containing crocin, crocetin and safranal; studied in relation to mood, stress, sleep quality, sexual function and antioxidant activity.

Key benefits and what to expect

Where does the hormonal link come from? Mostly from zinc. Each capsule supplies 11 mg, or 110% of the nutrient reference value, and zinc contributes to the maintenance of normal testosterone levels in the blood as well as to normal fertility and reproduction. It also supports normal immune function, cognitive function and the maintenance of normal bones, hair, nails and skin.

Everyday energy is the second pillar. Niacin, at 20 mg (125% NRV), contributes to normal energy-yielding metabolism and to the reduction of tiredness and fatigue. It also contributes to the normal functioning of the nervous system and to normal psychological function, which matters when you are trying to stay sharp through a long working day.

Then there are the amino acids. L-citrulline is a precursor of arginine and nitric oxide and is studied in relation to healthy blood flow and physical performance. L-carnitine carries fatty acids into the mitochondria, where they are used as fuel, so it is linked with normal fat metabolism, cellular energy production and recovery after exercise.

The plant extracts round out the formula. Mucuna pruriens is a natural source of L-DOPA, studied in relation to male reproductive health, stress, mood and motivation. Maca is a traditional Andean adaptogen studied in relation to libido, sexual wellbeing and stamina. Saffron is studied in relation to mood, stress and sleep quality.

Finally, maritime pine bark and grape skin are polyphenol sources studied for antioxidant activity and healthy circulation, while zinc also contributes to the protection of cells from oxidative stress. The practical bonus is convenience: one capsule a day with 601 mg of declared actives, to be combined with a balanced diet, regular activity and good sleep.

Possible side effects to be aware of

Most people tolerate a supplement like this well, but it is only fair to say what can happen. Mild digestive discomfort or sensitivity to certain components may occur, as stated by the supplier. Taking the capsule with a meal usually helps, particularly because zinc on an empty stomach can cause nausea or an upset stomach.

Some individual ingredients have their own known quirks. Niacin can cause flushing, meaning warmth, redness or tingling of the skin, mainly at higher intakes, so at 20 mg per capsule it is uncommon. L-carnitine can occasionally cause nausea, stomach discomfort, diarrhoea or a fishy body odour, and L-citrulline may cause mild gastrointestinal discomfort in sensitive people.

Mucuna pruriens contains L-DOPA and can occasionally cause nausea, headache, dizziness, agitation, trouble sleeping or palpitations in sensitive individuals. Maca may cause digestive discomfort, bloating or, rarely, sleep disturbance and restlessness. Allergic reactions are possible in anyone sensitive to an ingredient, including grape, saffron or legumes. If anything feels wrong, stop taking it and speak to a healthcare professional.

Who should avoid it: precautions

Potensal is not recommended for anyone under 18, nor during pregnancy or breastfeeding. It should not be used if you have a known allergy or hypersensitivity to any of the ingredients.

Mucuna pruriens contains L-DOPA, so avoid the product or seek medical advice first if you take antidepressants (MAO inhibitors), antipsychotics or Parkinson's disease medication (levodopa), or if you have a psychiatric disorder, melanoma or a history of skin cancer. Maca contains glucosinolates that may affect the thyroid in sensitive people, so anyone with a thyroid disorder should ask for advice.

If you take regular medication, speak to your doctor before starting. This applies in particular to blood thinners such as warfarin, antidiabetic medication, and blood pressure or erectile dysfunction treatments, including nitrates and PDE5 inhibitors, because L-citrulline, L-carnitine, pine bark and grape extracts may influence blood pressure, clotting or blood sugar. Zinc can also reduce the absorption of some antibiotics (quinolones and tetracyclines), so ask a pharmacist about timing.

Medical advice is also sensible if you have a hormone-sensitive condition such as a prostate disorder or a hormone-dependent cancer, kidney or liver disease, a heart condition or any other pre-existing problem. Stop use and see a doctor if you notice persistent or unusual symptoms. This supplement does not replace a diagnosis or treatment, and low testosterone should always be assessed by a doctor.

How it works

So what is actually going on inside that one capsule? Think of it in three layers. The first is nutritional: zinc contributes to the maintenance of normal testosterone levels in the blood, and niacin takes part in normal energy-yielding metabolism. These are recognised roles for these nutrients, and they are the foundation of the formula.

The second layer is the amino acids. L-citrulline is converted in the body into L-arginine, a precursor of nitric oxide, which is why it is studied in relation to blood flow and exercise performance. L-carnitine has a different job: it carries long-chain fatty acids into the mitochondria, the cell's power stations, so they can be used for energy. That is why it is looked at in relation to fatigue and recovery.

The third layer is plant extracts. Mucuna pruriens naturally contains L-DOPA, a precursor of dopamine, and is studied for mood, motivation and male reproductive health. Maca is a traditional Andean adaptogen studied for libido and stamina, though it has no direct effect on circulating testosterone. Pine bark, grape skin and saffron bring polyphenols and other compounds studied for antioxidant activity, circulation, mood and sleep. Research on these botanicals is ongoing, and results vary between individuals.
