My Harvey Nutrition Vitamin D3 & Vitamin K2 Testosterone Booster Review First Look

I was running out of supplements this week and after a slight break in training and then going back at it all guns blazing and not warming up left me with what felt like a broken neck.

No matter how much I got my bird to massage my neck with her boobs, it still aches now.

However, I may just keep saying it aches for much longer to drag that little number out…

However, I needed some more testosterone boosting supplements. I do not want to see a depletion of my natural testosterone levels anytime soon.

What a reduction in testosterone means is:

Loss of muscle mass
Loss of strength
Increased risk of osteoporosis
A change in mood and outlook on life
Irratibility
Increase of fat mass
Cardiovascular health risks
Reduced energy levels
Loss of libido

There are some way to combat this, and resistance training or weightlifting is helpful, particularly if compound exercises are employed, hence my love for them.

You can also incorporate a testosterone booster supplement in to your lifestyle as I did when I started to notice the beginnings of a change when I hit 32 years of age.

Seeing as I am interested in weight lifting and trying to increase my strength it is of a double concern that my testosterone levels are maintained at a high level.

As such, I normally use TestoFuel because it contains nine proven ingredients that are able to stimulate more testosterone production.

However, this time, I wanted to see what else is available to maximize my results and workload.

Ingredients

Vitamin D

D3 is a great Testosterone boosting vitamin that must be taken advantage of to trigger further production of Testosterone in your body.

However, there are two types of Vitamin D. There’s calciferol (vitamin D₂) and cholecalciferol (vitamin D₃) – we are only interested in cholecalciferol which is D3; this is the type our skin synthesizes from the sun and becomes a hormone which results in the increases in our testosterone.

Research by the US Library of Medicine has shown that testosterone productions are increased with Vitamin D3 supplementation. [1]

There’s a plenty of articles I have written covering the benefits of D3 you can read about, here, here and here.

Vitamin K2

K2 has been shown to help maintain plasma and testes levels of testosterone. [2]

Dose

The daily dose is 1 tablet per day which is not the best dosing strategy.

It is recommended that we have at least 4 tablets spread evenly across the day, as per the best testosterone booster on the market.

This way your body has a constant trickle of the ingredients to work with in order to stimulate testosterone and to ensure that if you get a large hit of ingredients it isn’t wasted if your body doesn’t require them.

A daily serving is a fairly robust and strong 5,000iu of D3 and 100mcg of K2. This is better than what is included in the better products such as Prime Male.

Effects & Benefits

In this testosterone booster supplement there’s just two ingredients.

Both of them are effective at helping to raise testosterone levels.

They are both offered in high, beneficial doses too.

D3 and K2 is often found in the best testosterone boosters.

Negatives

The problem with this supplement is not the actual ingredients included but what it omits.

That said, this is not really marketed a sa testosterone booster but more of a vitamin supplement.

So, while this is a great product to have, for maximum effects you will need to take additional vitamins and mineral.

The premium and effective testosterone boosters such as TestoFuel contain 9 proven ingredients, a larger daily dose and has enough pills to provide a constant trickle of ingredients.

This makes products like TestoFuel more convenient and overall, better value.

My Harvey Nutrition Vitamin D3 & Vitamin K2 Testosterone Booster Review Conclusion

As already mentioned I use TestoFuel which includes 9 effective and proven testosterone boosting ingredients….it is not on it’s own though, you can check out other competent testosterone boosters, here.

For me, TestoFuel has provided some great, noticeable results. Mainly my strength and muscular definition has increased.

Not only that, I feel much better overall.

Additionally, when I used it as a post cycle therapy (PCT) after a cycle of prohormones it pulled me out of the lull of decreased natural testosterone levels which was killing my libido…and my confidence

This does provide a massive 5,000iu of D3 and much higher levels of K2 than found in even the leading testosterone booster supplements.

So, if you wish to use this product and you want to increase your testosterone levels to their maximum potential, you should at least find a D-Aspartic Acid supplement and a ZMA supplement too.

Combined, these will offer a well rounded profile of vitamins and minerals that will help stimulate more testosterone.

Take a look at what works to maximize your workouts.

D3 & K2 Rivals

Let’s see what other best rated natural testosterone booster supplements are pitched against Harvey Nutrion.

Prime Male

It is hard not to make a good case for Prime Male because it is so effective due to its large number of proven and distinctly well regarded ingredient profile.

Prime Male has been proven to help increase natural testosterone levels and is backed by some great figures from the world of sport and film.

Developed with the older man in mind, it is still useful for all ages, and women.
