Musqle On Cautions: Side Effects and Who Should Ask First
What suits one person may not suit another. Below are the general cautions that go with the ingredients the seller lists, the people who should take advice before using Musqle On, and the signs that mean you should stop.
- Check with a GP or pharmacist if you take medicine, have a health condition, or are pregnant or breastfeeding
- Zinc at 22 mg sits near the 25 mg upper level for supplements, so avoid doubling up
- Not for under-18s, and no replacement for medical advice about tiredness, mood or sexual difficulties

Safety in a nutshell
The zinc and niacin amounts are high enough that you should avoid stacking other products that contain them. Several ingredients are plant extracts that can interact with certain medicines, and we cannot say how this particular combination will behave for you.
This is general information, not medical advice. If you are unsure, show a pharmacist the label, and stop taking the capsules if you feel unwell.
People who should take advice before ordering
Please speak to a GP or pharmacist first if any of the following describes you:
- You are under 18, since the product is not meant for children or teenagers.
- You are pregnant or breastfeeding.
- You use prescribed or over-the-counter medicines, above all blood thinners, diabetes medicine, or blood-pressure or heart tablets.
- You live with a medical condition, especially one affecting the heart, liver, kidneys, prostate or hormones, or you are being treated for one.
- You have surgery planned in the coming weeks.
Ongoing tiredness, low mood or trouble with sex can each have many causes, and some can be treated. A supplement cannot tell you what is behind them, so book a GP appointment if they concern you.

How much zinc and niacin is listed
The seller's table shows 22 mg of zinc. UK and EU advisers regard roughly 25 mg a day from supplements as the upper level, and intakes above it over a long period can disrupt copper absorption. Anyone already taking a multivitamin or another zinc product should check its zinc content before adding this one.
The table also shows 40 mg of niacin. As nicotinic acid, niacin can bring on a harmless but noticeable flush of warmth, redness and tingling across the face and neck. The form is not stated, so be prepared. Talk to a pharmacist first if you have liver disease, gout or stomach ulcers, or you take cholesterol medicine.

Effects on the stomach
Some people get nausea, cramps or loose stools from L-carnitine and citrulline, more so on an empty stomach or with too little water. That is why the seller recommends two large glasses of water ahead of a main meal. If the capsules upset you, stop and ask a pharmacist, and do not change the dose yourself.
The seller adds that the capsules may be opened and mixed into water. Should you do that, follow the pack's directions, bearing in mind that the taste and the speed at which you drink it may change.

Plant extracts and your medicines
Pine bark, grape skin, maca and saffron are plant-derived entries, and we are not aware of authorised health claims for any of them. Each carries general cautions. Pine bark and grape skin extracts may influence blood clotting or blood sugar in some people, which is relevant to anyone on blood thinners or diabetes medicine. The 10 mg of saffron extract is a small amount, but people sensitive to related plants may still react.
If you are allergic to any ingredient, do not take the product. Since the seller's pages list different formulas, compare the label on your pack with the table in our ingredients guide before the first dose.

Signs to stop and seek help
Stop taking Musqle On and get medical advice if you notice a rash, swelling, trouble breathing, chest pain, a racing or irregular heartbeat, severe stomach pain, yellow skin or eyes, or any symptom that worries you. In an emergency, ring 999. A suspected problem with a food supplement can also be reported to your local trading standards office or the Food Standards Agency.
Store the pack as directed and out of children's reach, and never go over the stated dose. For the wider picture, see the main guide.
